1. Benefits

The invoice and credit note provides simple support for complex invoicing, where there is a need for credit note in addition to an invoice. Other potential benefits are, among others:

Can be mandated as a basis for national or regional eInvoicing initiatives.
Procurement agencies can use them as basis for moving all invoices into electronic form. The flexibility of the specifications allows the buyers to automate processing of invoices gradually, based on different sets of identifiers or references, based on a cost/benefit approach.
SME can offer their trading partners the option of exchanging standardised documents in a uniform way and thereby move all invoices/credit notes into electronic form.
Large companies can implement these transactions as standardised documents for general operations and implement custom designed bi-lateral connections for large trading partners.
Supports customers with need for more complex interactions.
Can be used as basis for restructuring of in-house processes of invoices.
Significant saving can be realised by the procuring agency by automating and streamlining in-house processing. The accounting can be automated significantly, approval processes simplified and streamlined, payment scheduled timely and auditing automated.

2. Parties and roles

The diagram below shows the roles involved in the invoice and credit note transactions. The customer and invoice receiver is the same entity, as is the supplier and the invoice sender.

2.1. Parties

Customer: The customer is the legal person or organisation who is in demand of a product or service. Examples of customer roles: buyer, consignee, debtor, contracting authority.
Supplier: The supplier is the legal person or organisation who provides a product or service.

2.2. Roles

Creditor: One to whom a debt is owe. The party that claims the payment and is responsible for resolving billing issues and arranging settlement. The party that sends the invoice or credit note. Also known as invoice issuer, accounts receivable or seller.
Debtor: One who owes debt. The party responsible for making settlement relating to a purchase. The party that receives the invoice or credit note. Also known as invoicee, accounts payable, or buyer.

3. Business processes

3.1. General invoicing process

The invoicing process includes issuing and sending the invoice and the credit note from the supplier to the customer and the reception and handling of the same at the customer’s site.

The invoicing process is shown in this work flow:

A supplier issues and sends an invoice to a customer. The invoice refers to one order and a specification of delivered goods and services.

An invoice may also refer to a contract or a frame agreement. The invoice may specify articles (goods and services) with article number or article description.

The customer receives the invoice and processes it in the invoice control system leading to one of the following results:
1. The customer fully approves the invoice, posts it in the accounting system and passes it on to be paid.
2. The customer completely rejects the invoice, contacts the supplier and requests a credit note.
3. The customer disputes parts of the invoice, contacts the supplier and requests a credit note and a new invoice.

The diagram below shows the basic invoicing process with the use of this Peppol BIS profile. This process assumes that both the invoice and the credit note are exchanged electronically.

This profile covers the following invoice processes:

P1	Invoicing of deliveries of goods and services against purchase orders, based on a contract
P2	Invoicing deliveries of goods and services based on a contract
P3	Invoicing the delivery of an incidental purchase order
P4	Pre-payment
P5	Spot payment
P6	Payment in advance of delivery
P7	Invoices with references to a despatch advice
P8	Invoices with references to a despatch advice and a receiving advice
P9	Credit notes or invoices with negative amounts, issued for a variety of reasons including the return of empty packaging

4. Invoice functionality

An invoice may support functions related to a number of related (internal) business processes. This Peppol BIS shall support the following functions:

Accounting
Invoice verification against the contract, the purchase order and the goods and service delivered
VAT reporting
Auditing
Payment

In the following chapters an assessment is made of what information is needed for each of the functions listed above and whether it is in scope or out of scope for this Peppol BIS.

Please also see Invoice and credit note business requirements for further details.

Explicit support for the following functions (but not limited to) is out of scope:

Inventory management
Delivery processes
Customs clearance
Marketing
Reporting

4.1. Accounting

Recording a business transaction into the financial accounts of an organization is one of the main objectives of the invoice. According to financial accounting best practice and VAT rules every Taxable person shall keep accounts in sufficient detail for VAT to be applied and its application checked by the tax authorities. For that reason, an invoice shall provide for the information at document and line level that enables booking on both the debit and the credit side.

Detailed requirements for supporing accounting functionality can be found at Accounting requirements

4.2. Invoice verification

This process forms part of the Buyer’s internal business controls. The invoice shall refer to an authentic commercial transaction. Support for invoice verification is a key function of an invoice. The invoice should provide sufficient information to look up relevant existing documentation, electronic or paper, for example, and as applicable:

the relevant purchase order
the contract
the call for tenders, that was the basis for the contract
the Buyer’s reference
the confirmed receipt of the goods or services
delivery information

An invoice should also contain sufficient information that allows the received invoice to be transferred to a responsible authority, person or department, for verification and approval.

Detailed requirements for supporing accounting functionality can be found at Invoice verification requirements

4.3. Auditing

Companies audit themselves as means of internal control or they may be audited by external parties as part of a legal obligation. Accounting is a regular, ongoing process whereas an audit is a separate review process to ensure that the accounting has been carried out correctly. The auditing process places certain information requirements on an invoice. These requirements are mainly related to enable verification of authenticity and integrity of the accounting transaction.

Invoices, conformant to this Peppol BIS support the auditing process by providing sufficient information for:

identification of the relevant Buyer and Seller
identification of the products and services traded, including description, value and quantity
information for connecting the invoice to its payment
information for connecting the invoice to relevant documents such as a contract and a purchase order

Detailed requirements for supporing accounting functionality can be found at Auditing requirements

4.4. VAT Reporting

The invoice is used to carry VAT related information from the Seller to the Buyer to enable the Buyer and Seller to correctly handle VAT booking and reporting. An invoice should contain sufficient information to enable the Buyer and any auditor to determine whether the invoice is correct from a VAT point of view.

The invoice shall allow the determination of the VAT regime, the calculation and description of the tax, in accordance with the Directive 2006/112/EC and subsequent amendments.

Detailed requirements for supporing accounting functionality can be found at VAT reporting requirements

4.5. Payment

An invoice represents a claim for payment. The issuance of an invoice may take place either before or after the payment is carried out. When an invoice is issued before payment it represents a request to the Buyer to pay, in which case the invoice commonly contains information that enables the Buyer, in the role of a debtor, to correctly initiate the transfer of the payment, unless that information is already agreed in prior contracts or by means of payment instructions separately lodged with the Buyer.

If an invoice is issued after payment, such as when the order process included payment instructions or when paying with a credit card, online or telephonic purchases, the invoice may contain information about the payment made in order to facilitate invoice to payment reconciliation on the Buyer side. An invoice may be partially paid before issuing such as when a pre-payment is made to confirm an order.

Invoices, conformant with this specification should identify the means of payment for settlement of the invoice and clearly state what payment amount is requested. They should provide necessary details to support bank transfers in accordance with the Single Euro Payments Area (SEPA) for payments in Euro and the relevant national payment practices for other currencies. Payments by means of Credit Transfer, Direct debit, and Payment Card are in scope.

Detailed requirements for supporing accounting functionality can be found at Payment requirements

4.6. Negative invoices and credit notes

In line with requirements of EN 16931 this BIS supports negative grand totals in order to open up for a wider spectrum of invoicing processes.

Examples of such processes are

Preliminary (estimated) consumption invoice that is balanced out in a later meter-based invoice;
Pre-payment (with or without VAT) is settled through a final invoice; and
Some user communities prefer to use negative invoice rather than credit note when correcting transactions.

This has the following implications on the transaction format:

The invoice (now with “negative invoice capacity”) can function as an alternative to the credit note. Invoice-generating systems may implement either option, while invoice-receiving systems have to support both of them.
The transaction format for credit note has to be designed to accommodate for negative grand total, as well; this is because an entire negative invoice may have to be balanced out by means of a credit note.

Attention is drawn to the intrinsic differences between credit note and negative invoice when it comes to convey crediting information.

6. Semantic datatypes

Semantic data types are used to bridge the gap between the semantic concepts expressed by the information elements defined in the semantic model from EN 16931 and the technical implementation. The semantic data types define the allowed value domain for the content, and any additional information components (attributes) needed in order to ensure its precise interpretation.

The details of the technical implementation can be found in [Detailed UBL message guideline]

6.1. Primitive types

Semantic data type content may be of the following primitive types. These primitive types were taken from ISO 15000-5:2014, Annex A.

Primitive type	Definition
Binary	A set of finite-length sequences of binary digits.
Date	Time point representing a calendar day on a time scale consisting of an origin and a succession of calendar ISO 8601:2004.
Decimal	A subset of the real numbers, which can be represented by decimal numerals.
String	A finite sequence of characters.

Decimal

A subset of the real numbers, which can be represented by decimal numerals.

String

A finite sequence of characters.

6.2. Semantic data types

The different semantic data types are described in the tables below, where various features such as attributes, format, and decimals as well as the basic type are defined for each semantic data type. They are based on ISO 15000-5:2014.

When used in an instance of an invoice, each data element will contain data. In the below tables this is identified as the “content”. Whenever a business term is used this term shall always have content and therefore the content is always mandatory.

6.2.1. Amount

An amount states a numerical monetary value. The currency of the amount is defined as a separate business term.

Amount is floating up to two fraction digits.

7. Value added tax (VAT)

The chapters below describe the different VAT informations that can be provided in a Peppol invoice or credit note.

Please also see VAT category codes for details on the VAT category code list, and Calculation of VAT for detailed explanation and example on how to perform the calculations for VAT Breakdown.

7.1. Line VAT Information

Each invoice line shall have the invoiced item VAT category code (BT-151), and for all VAT categories except "Not subject to VAT" (O), the VAT rate shall be provided.

7.2. Document level allowance or charge

Each document level charge or allowance must have the Document level allowance or charge VAT category code (BT-95 and BT-102), and for all VAT categories except "Not subject to VAT" (O), the VAT rate shall be provided.

7.3. VAT Breakdown

One VAT Breakdown shall be provided for each distinct combination of VAT category code and VAT rate found in either the line VAT information or the Document level allowance or charges. For some VAT categories, the VAT rate shall be zero, and hence the rate is not needed in order to group the VAT Breakdown for these.

Please note that for the VAT rate, only significant decimals should be considered, i.e any difference in trailing zeros should not result in different VAT breakdowns.

Example 1. Example

Invoice line 1 has category code = S and VAT rate = 25
Invoice line 2 has category code = S and VAT rate = 25.00
This should result in only one VAT Breakdown.

7.4. Invoice total VAT amount

The invoice total VAT amount (BT-110) is the sum of all VAT Category VAT amounts (BT-117)

8. Rounding

To minimize the risk of differences due to rounding, the following rules apply:

All document level amounts shall be rounded to two decimals for accounting
Invoice line net amount shall be rounded to two decimals
Results from calculations involving already rounded amounts are not subject to rounding, like payable amounts and total amounts included VAT.

Please also see Calculation for details on how to calculate the different amounts.

9.1.2. Element for rounding amount, the PayableRoundingAmount

It is possible to round the expected payable amount.

The element cac:LegalMonetaryTotal/cbc:PayableRoundingAmount is used for this purpose and is specified on the header level. This value shall be added to the value in cac:LegalMonetaryTotal/cbc:PayableAmount.

Example: Amount 999.81 rounded to 1000. PayableRounding Amount = 0.19

9.2. Calculation on line level

9.2.1. Item net price (BT-146)

If gross price and discount exist, the Item net price has to equal with the item gross price less the item price discount.

Calculation formula:

\$"Item net price" = "Item gross price (BT-148)" - "Item price discount (BT-147)"\$

UBL example of item net price

<cac:Price>
    <cbc:PriceAmount currencyID="EUR">410</cbc:PriceAmount>(3)
    <cbc:BaseQuantity unitCode="C62">1</cbc:BaseQuantity>
    <cac:AllowanceCharge>
        <cbc:ChargeIndicator>false</cbc:ChargeIndicator>
        <cbc:Amount currencyID="EUR">40</cbc:Amount>(2)
        <cbc:BaseAmount currencyID="EUR">450</cbc:BaseAmount>(1)
    </cac:AllowanceCharge>
</cac:Price>

1	Item gross price
2	Item price discount
3	\$"Item price net amount" = "Item gross price" - "Item price discount"\$

9.2.2. Invoice line net amount (BT-131)

The invoice line net amount (BT-131) is as the name implies the net amount without VAT, and inclusive of line level allowance and charges.

The formula for calculating the invoice line net amount is:

\$"Item line net amount" = (("Item net price (BT-146)" div "Item price base quantity (BT-149)")\$
\$times ("Invoiced Quantity (BT-129)")\$
\$+ "Invoice line charge amount (BT-141)" - "Invoice line allowance amount (BT-136)"\$

As the line net amount must be rounded to two decimals, please note that the different parts of the calculation must be rounded separately.
I.e the result of \$"Item line net amount" = (("Item net price (BT-146)" div "Item price base quantity (BT-149)") times ("Invoiced Quantity (BT-129)")\$ must be rounded to two decimals, and the allowance/charge amounts are also rounded separately.

UBL example of invoice line net amount where no line allowance/charge exist

<cbc:InvoicedQuantity unitCode="C62">10</cbc:InvoicedQuantity>(3)
<cbc:LineExtensionAmount currencyID="EUR">1000.00</cbc:LineExtensionAmount>(4)

<!-- Code omitted for clarity-->

<cac:Price>
    <cbc:PriceAmount currencyID="EUR">200</cbc:PriceAmount>(1)
    <cbc:BaseQuantity unitCode="C62">2</cbc:BaseQuantity>(2)
</cac:Price>

1	Item net price
2	Item price base quantity
3	Invoiced quantity
4	\$"Invoice line net amount" = (("Item net price" div "Item price base quantity") times ("Invoiced Quantity")\$

UBL example of invoice line net amount where line allowance and charge exist

</cac:AllowanceCharge>

<!-- Code omitted for clarity-->

<cac:Price>
    <cbc:PriceAmount currencyID="EUR">100</cbc:PriceAmount>(1)
</cac:Price>

1	Item net price
2	Line charge amounts
3	Line allowance amount
4	Invoiced quantity
5	\$"Invoice line net amount" = ("Item net price" times "Invoiced Quantity") + "line charge amount" - "line allowance amount"\$

9.3. Calculation of allowance/charge amount

Allowance and charge on document- and line level consists of elements carrying information on the allowance/charge base amount and the allowance/charge percentage. These are, if present in the invoice instance, used for calculating the allowance/charge amount.

If base amount is present, the percentage shall also be present, and if percentage is present, the base amount shall also be present, and the calculation of the amount shall be:

\$"Amount" = "Base amount" times ("Percentage" div 100)\$

UBL example of calculations of allowances and charges where base amount and percentage exist

<cac:AllowanceCharge>
    <cbc:ChargeIndicator>true</cbc:ChargeIndicator>
    <cbc:AllowanceChargeReasonCode>CG</cbc:AllowanceChargeReasonCode>
    <cbc:AllowanceChargeReason>Cleaning</cbc:AllowanceChargeReason>

        </cac:TaxScheme>
    </cac:TaxCategory>
</cac:AllowanceCharge>

1	Base amount, to be used with the percentage to calculate the amount
2	Charge percentage
3	\$"Base amount" times ("Percentage" div 100) = "Amount"\$

        </cac:TaxScheme>
    </cac:TaxCategory>
</cac:AllowanceCharge>

1	Amount of allowance without calculations based on base amount and percentage

9.4. Calculation of VAT

One VAT Breakdown shall be provided for each distinct combination of VAT category code and VAT rate found in either the line VAT information or the Document level allowance or charges.

For each distinct combination of VAT category code and VAT rate the calculations are:

\$"VAT category taxable amount (BT-116)" = sum("Invoice line net amounts (BT-131)")\$
\$+ "Document level charge amount (BT-99)" - "Document level allowance amount (BT-92)"\$

\$"VAT category tax amount (BT-117)" = "VAT category taxable amount (BT-116)" times ("VAT rate (BT-119)" div 100)\$

For VAT Breakdown where the VAT Category is "Not subject to VAT" (O), the VAT category tax amount shall be zero.

10.3. References

Support for invoice verification is a key function of an invoice. The invoice should provide sufficient information to look up relevant existing documentation, electronic or paper.

Any reference element should contain valid information, if you do not have a reference, the element should not be present in the instance document.

The invoice and credit note transactions supports the following references to existing documentation:

10.3.1. Purchase order and sales order reference

The purchase order is conditional. If order reference exist, use that, else use Buyer reference (see Buyer reference).

The customer will issue an order with a unique order number. This unique purchase order number should be supplied as the order reference on the invoice.

If order reference is stated at header level, the order reference element on line level can be used to state the order line numbers.

A sales order is issued by the seller, confirming the sale of specified products.

In the invoice, both a purchase order and a sales order reference can be given, but be aware that an invoice instance cannot have a sales order reference, without the corresponding purchase order reference.

UBL example or order and sales order reference

<cac:OrderReference>
    <cbc:ID>o-998877</cbc:ID>(1)
    <cbc:SalesOrderID>so-12343</cbc:SalesOrderID>(2)
</cac:OrderReference>

1	Purchase order reference
2	Sales order reference

10.3.2. Buyer reference

The buyer reference, known as Your ref, is conditional. An invoice shall have either the buyer reference or the order reference (see Purchase order and sales order reference)

The element is used for the reference of who ordered the products/services. Example being the name of the person ordering, employee number or a code identifying this person or department/group. Your ref is often used for internal routing at recipient, and hence it is important to fill this element with the correct values according to the need of the recipient.

If neither buyer reference nor a reference to an order is supplied by the customer, the name of the person ordering or appointed for the customer can be supplied in buyer reference if known by the supplier.

When reference is provided by the customer, the correct element shall contain the provided reference.

UBL example of buyer reference

<cbc:BuyerReference>0150abc</cbc:BuyerReference>

10.3.3. Invoiced object identifier

The invoiced object identifier is the identifier for an object on which the invoice is based, given by the Seller. Examples may be a subscription number, telephone number, meter point, vehicle, person etc., as applicable.

If it is not clear to the receiver what scheme is used for the identifier, a conditional scheme identifier should be used, that shall be chosen from the Invoiced object identifier scheme.

The invoiced object reference is provided by using the element cac:AdditionalDocumentReference with the document type code = 130

UBL example of invoiced object identifier

<cac:AdditionalDocumentReference>
    <cbc:ID schemeID="ABT">DR35141</cbc:ID>(1)
    <cbc:DocumentTypeCode>130</cbc:DocumentTypeCode>(2)
</cac:AdditionalDocumentReference>

1	Scheme identifier from UN/CEFACT 1153 code list
2	Document type code shall be ´130´ to indicate Invoiced object

10.3.4. Contract reference

To reference or match an invoice to a purchase contract, the contract number could be specified like this:

UBL example of contract reference

<cac:ContractDocumentReference>
    <cbc:ID>framework no 1</cbc:ID>
</cac:ContractDocumentReference>

10.3.5. Despatch and receipt advice references

To reference or match an invoice to a despatch or receipt advice use the following elements:

UBL example of despatch and receipt advice

<cac:DespatchDocumentReference>
    <cbc:ID>despadv-3</cbc:ID>(1)
</cac:DespatchDocumentReference>
<cac:ReceiptDocumentReference>
    <cbc:ID>resadv-1</cbc:ID>(2)
</cac:ReceiptDocumentReference>

1	Despatch advice
2	Receipt advice

10.3.6. Tender reference

To identify the call for tender or lot the invoice relates to, use the 'OriginatorDocumentReference'. The identifier is, in most cases, the Procurement Procedure Identifier.

UBL example of tender reference

<cac:OriginatorDocumentReference>
    <cbc:ID>ppid-123</cbc:ID>
</cac:OriginatorDocumentReference>

10.3.7. Project reference

The project reference is optional to use, and is sent in an invoice in the element cac:ProjectReference/cbc:ID. In a credit note, this element does not exist, and project reference is sent by using the element cac:AdditionalDocumentReference[cbc:DocumentTypeCode='50']/cbc:ID.

NOTE: When sending the project reference, only the cbc:ID and the cbc:DocumentTypeCode are allowed in the cac:AdditionalDocumentReference element.

UBL example of proejct reference in an invoice

<cac:ProjectReference>
    <cbc:ID>project333</cbc:ID>
</cac:ProjectReference>

UBL example of project reference in a credit note

<cac:AdditionalDocumentReference>

    <cbc:DocumentTypeCode>50</cbc:DocumentTypeCode>(1)
</cac:AdditionalDocumentReference>

1	Code 50 indicating this is a project reference
2	The project reference identifier

10.4. Preceding invoice references

A credit note or negative invoice can refer to one or more initial invoice(s). This is done in the business group BG-3 Preceding invoice reference, providing the invoice number and issue date. The issue date shall be provided in case the preceding invoice reference is not unique.

In case correction applies to a large number of invoices, the invoicing period (BG-14), as necessary combined with a clarifying invoice note (BT-22), may instead be be given at document level.

UBL example of preceding invoice information

<cac:BillingReference>
    <cac:InvoiceDocumentReference>
        <cbc:ID>123</cbc:ID>(1)
        <cbc:IssueDate>2017-10-20</cbc:IssueDate>(2)
    </cac:InvoiceDocumentReference>
</cac:BillingReference>
<cac:BillingReference>(3)
    <cac:InvoiceDocumentReference>
        <cbc:ID>124</cbc:ID>
    </cac:InvoiceDocumentReference>
</cac:BillingReference>

1	The identifier is mandatory if `cac:BillingReference` is provided
2	Issue date shall be filled if the invoice reference is not unique
3	Repeat the `cac:BillingReference` to add several preceding invoice references

Applies to the line level and is included in the calculation of the line amount.

Several allowances and charges may be supplied
Specification of VAT for allowances and charges shall not be specified, as the VAT category stated for the invoice line itself, applies also to the allowances or charges of that line.
The sum of all allowances and charges on the line level shall be taken into account, subtracted or added, when calculating the line extension amount . These line level allowances and charges shall not be calculated into the header level elements.

The line level Price element

A way to inform the buyer how the price is set. Is also relevant if the seller or buyer want to post the allowance in their accounting systems. The price itself shall always be the net price, i.e. the base amount reduced with a discount (allowance).

Only one occurence of allowance (discount) is allowed.
Specification of VAT for allowance shall not be specified
Allowance related to Price shall not be part of any other calculations.
Allowance related to Price may specify amount and the base amount.

Further details of the calculation of allowance/charge amount, can be found in Calculation of allowance/charge amount

10.6. VAT accounting currency

Article 230 of Directive 2006/112/EC states:

The amounts which appear on the invoice may be expressed in any currency, provided that the amount of VAT payable is expressed in the national currency of the Member State in which the supply of goods or services takes place, using the conversion mechanism laid down in Article 91.

If the invoice currency is different from the national currency, this is expressed in the invoice by stating the national currency in the element VAT accounting currency (BT-6), and the amount of VAT payable in national currency is stated in the element Invoice total VAT amount in accounting currency (BT-111). The exchange rate to use for calculating is described in Article 91 of Directive 2006/112/EC. The exchange rate is not specified in the invoice instance, and hence this calculation is not validated.

11. Code lists

The following chapters give an overview of the restricted set of codes that is used in this Peppol BIS. For most codes the restriction is only to add a dated reference of the code list, but for the Invoice Type Code a subset of valid values have been established.

11.1. Code lists for coded elements

11.1.1. Code list for invoice type code (BT-3)

The following sub-chapters give an overview of the restricted set of invoice type codes (BT-3) that is used in this Peppol BIS Billing.

The table indicates the name and description of each code, as well as a column "Synonym with" to indicate how this invoice type can be processed if the recipient does not have a separate process/work flow for this code, and as you will see, all invoice types valid in this profile can be processed as a commercial invoice (380) and all credit note types as Commercial credit note (381). Some recipients might have separate processes or work flows for some of these types, and can then use these processes.

The table also gives information on what message type is to be used in the UBL syntax for the different codes.

12. Peppol Identifiers

Peppol has defined a Peppol Policy for identifiers, policy 8 that specifies how to use identifiers in both its transport infrastructure and within the documents exchanged across that infrastructure. It also introduces principles for any identifiers used in the Peppol environment. The policies that apply to this BIS are the following:

12.1. Profiles and messages

All messages contains Business process type (BT-23, ProfileID in UBL) and Specification identifier (BT-24, CustomizationID in UBL). Business process type identifies what business process a given message is part of, and Specification identifier identifies the kind of message and the rules applied.

Profiles are connected to one business process, and may contain multiple document types. Valid document instances shall contain corresponding Business process type and Specification identifier.

Specification identifier is a string without spaces. The list below contains spaces in Specification identifier to make them easier to read. Make sure to remove any spaces before use.

12.2. Profile 01 - Billing

In the table below you will find the values to be used as the specification identifier (BT-24) and the business process type (BT-23) for this profile

Type Element cbc:CustomizationID Element cbc:ProfileID

Invoice and credit note

urn:cen.eu:en16931:2017#
compliant#urn:fdc:peppol.eu:2017:poacc:billing:3.0

urn:fdc:peppol.eu:2017:poacc:billing:01:1.0

UBL example of profile identifier

<cbc:CustomizationID>urn:cen.eu:en16931:2017#compliant#urn:fdc:peppol.eu:2017:poacc:billing:3.0</cbc:CustomizationID>
<cbc:ProfileID>urn:fdc:peppol.eu:2017:poacc:billing:01:1.0</cbc:ProfileID>

13. UBL schemas and namespaces

The XML schemas used are

UBL Invoice 2.1 with the target namespace urn:oasis:names:specification:ubl:schema:xsd:Invoice-2
UBL CreditNote 2.1 with the target namespace urn:oasis:names:specification:ubl:schema:xsd:CreditNote-2

14. Validation

To optimize the flexibility in the validation process, each Peppol document is validated in different stages with shifting focus in every stage. The diagram below illustrates the different stages.

14.1. Validation Principles

Stages in the validation process:

Validation of syntax

For example:

Check well-formedness
Tag names and attributes shall be correctly written and follow the UBL 2.1 sequence
All UBL 2.1 mandatory elements shall be present.
The element’s contents shall be according to the element’s type definition.

Validation against EN 16931

To verify that the instance message is compliant to the european standard, like:

Valid codes for currencies, countries, tax etc.
Mandatory elements according to EN 16931.
Logical correlations between information element, i.e. that start date is lower than or equal to end date, calculations give the correct result etc.

CIUS - General rules

General rule that applies to all invoices and are triggered by the existence of one or more specific business term(s).

Example rule text
An invoice shall have a buyers reference or an order reference
Context that triggers the rule
Existence of either Buyer reference (BT-10) OR Purchased order reference (BT-13)

CIUS - Country qualified validation rules

Applies only for invoices issued in a specific country. The rule is triggered by the given country code of the seller (BT-40).

Example rule text
When the Seller is Swedish, the Legal Registration Number shall be numeric with 10 digits.
Context that triggers the rule
Existence of Seller/Address/CountryCode=‘SE’ AND existence of Seller/LegalRegistrationNumber

15. Transaction validation rules

15.1. Peppol transaction business rules

The following rules have been defined by OpenPeppol in addition to the rules adopted from EN 16931. These rules apply in all profiles that use this transaction specification.

Please also see Restrictions on EN16931 for further details on the restrictions imposed by these rules.

A.3. Restrictions on the supported processes

Chapter 5.2 in the EN 16931 defines the business processes supported by the EN 16931.

This Core Invoice Usage Specification (CIUS) has made restrictions to not explicitly support the following business processes:

P10 - Corrective invoicing: The process as descibed for corrective invoicing was seen as unclear as to the differentiating between a corrective invoice and a credit note, and this process was set to be out of scope.
P11 - Partial and final invoicing: Due to the fact that partial and final invoices does not require all information that is mandated, this process is out of scope for this Peppol BIS.
P12 - Self billing: Directive 2006/112/EC (Article 224) requires a specific process to be observed, involving prior agreement and a procedure where the supplier is to accept each invoice. Self-billing requires a specific set-up due to the requirements for prior agreement and procedure for the acceptance of each self-bill. Specific milestones have to be observed at time of setting it up as well as in the operation of self-billing.

A.4. Known Issues for profile 01 - Billing

BT-ID

Business Term

Known Issue

Work Around

BT-60, BT-90

Payee identifier with cardinality, Bank assigned creditor identifier

In the EN 16931 data model BT-60 and BT-90 are business terms that are defined independently of each other. Both map onto PayeeParty/PartyIdentification/ID. However, the cardinalities stated in the syntax block simultaneous use of the BT-60 and BT-90 identifiers. This situation might arise if the payment provision is to be based on factored SEPA direct debit.

None

Appendix B: Cross Industry Invoice

This Peppol BIS supports the optional use of the UN/CEFACT XML Cross Industry Invoice, D16B (CII), meaning that receivers of invoices can register in the SMP to receive CII invoices alongside the mandatory UBL version.

All invoice instances expressed in CII shall be compliant to the restrictions and rules made by this BIS, and hence a CII instance document, shall be validated against the Peppol specific rules, just as the UBL instance documents.

Specification identifier (BT-24) and business process type (BT-23) are the same in a CII instance as for the UBL instance, see Profile 01 - Billing

Appendix C: National rules

The following rules have been defined by Peppol Authorities in addition to the rules for Peppol BIS in general. These rules are affected based on the country of the seller, and will not affect invoices issued in other countries. They apply in all profiles that use this transaction specification.

National rules are provided by each country’s Peppol Authority, and if you need any changes or additions to these rules, please contact your Peppol Authority.
