Submission of a compliant electronic invoice as part of a public procurement or a concession contract
Last update
From 18 March 2023, within the context of a public procurement or concession contract, all economic operators must, with some exceptions, issue and submit their invoices in the form of compliant electronic invoices.
As a reminder, public procurement legislation considers as a public contract any contract concluded in writing:
- between an economic operator and a public sector body; and
- which has as its object the execution of works, the supply of products or the provision of services.
Thus, it is also a public contract in the case of:
- contracts which only concern small amounts, for example EUR 1,000 or even less; or
- contracts concluded via:
- a negotiated (direct) procedure between a public sector body and an economic operator without a public tender process; or
- any other procedure that would put different economic operators in competition.
Economic operators can send their electronic invoices:
- via Peppol (Pan European Public Procurement OnLine); or
- if they are not or not yet connected to Peppol, by using one of the 2 types of online forms available on MyGuichet.lu, namely:
- a form which allows to manually enter in the fields of the form the elements of an invoice and then to transmit these data; or
- a form, described below, that allows you to upload an already compliant electronic invoice and then to transmit it.
Other transmission channels than Peppol or MyGuichet.lu are not permitted. It is therefore not permitted, for example, to send compliant electronic invoices via email.
Who is concerned?
Economic operators concerned
Any economic operator that issues and wishes to submit invoices to a contracting authority or entity in the context of a public contract or a concession contract.
Exclusions
By way of derogation, the requirement to issue electronic invoices does not apply to public procurement contracts entered into:
- for the purpose of development cooperation;
- by diplomatic missions or consulates;
- as part of Luxembourg’s participation in international fairs and exhibitions held abroad; or
- as part of State visits, official visits or working trips abroad.
Prerequisites
The MyGuichet.lu platform is a useful option for economic operators that have no access – or do not yet have access – to the Peppol delivery network.
On the other hand, economic operators that already have an account with the Peppol network can use it to issue and submit their electronic invoices directly.
Preliminary steps
To submit electronic invoices through MyGuichet.lu, the economic operator must have a MyGuichet.lu business eSpace.
How to create a business eSpace on MyGuichet.lu
There are 2 possible scenarios:
- The person submitting the application is a new user of MyGuichet.lu. They must:
- first register on MyGuichet.lu; and
- then create a business eSpace.
- The person submitting the application already has a private eSpace on MyGuichet.lu. They can directly create a business eSpace without having to register again.
Further information as well as tutorials in relation with the business eSpace are available in our dedicated help page.
Note: any person can create a business eSpace. All necessary information is available on the help section on MyGuichet.lu mentioned above.
Deadlines
In the framework of a public procurement or concession contract, the obligation for economic operators to issue and transmit compliant electronic invoices via one of the authorised channels (Peppol or MyGuichet.lu) applies to all economic operators since 18 March 2023.
In addition, the obligation for public sector bodies to receive and process compliant electronic invoices applies:
- to central contracting authorities, e.g. ministries, since 18 April 2019; and
- to sub-central contracting authorities, e.g. communes, and contracting entities since 18 April 2020.
In addition, all public sector bodies have been required to be connected to the Peppol network since 18 December 2021 so that they can receive compliant electronic invoices via Peppol.
How to proceed
Filing of an XML document
The procedure can be completed with or without authentication.
Procedure with authentication
The economic operator, or their agent, who submits the request with authentication must have:
- a business eSpace on MyGuichet.lu;
- a LuxTrust product (e.g. Token, Smartcard or Signing Stick); or
- an electronic identity card (eID); or
- a digital ID issued by another EU country (eIDAS).
Note: it is preferable to use the procedure with authentication as it has several advantages over the procedure without authentication, namely
- the possibility of using the form's pre-filling functions with data already recorded in the business eSpace;
- the possibility of receiving the various acknowledgement sheets and confirmations directly in the business eSpace.
Procedure without authentication
The economic operator, or their agent, who submits the request without authentication needs a one-time access code (token) for each invoice.
The token must be requested in advance from the public sector body with which the public contract or concession contract has been concluded (contracting authorities or entities or concession authority).
Note: this procedure without authentication is intended for economic operators who have no means of authenticating themselves on MyGuichet.lu.
Entering the information
After entering the following information:
- the identity of the economic operator;
- the government administration department to which the invoice is addressed;
the person concerned can file the invoice by uploading, through MyGuichet.lu, a compliant electronic invoice – that is, an invoice compliant with the most recent version of the European standard on electronic invoicing which outlines the semantic data model for an electronic invoice, and with one of the syntaxes on the most recent list published by the European Commission.
The user will then receive confirmation of the submission of their compliant electronic invoice to the back office that distributes electronic invoices to public-sector bodies and, once the back office has processed the invoice:
- if the uploaded electronic invoice is compliant with the European standard, and is passed on to the final recipient: a message informing them that the electronic invoice has been successfully forwarded to the final recipient;
- if the submitted invoice is not compliant with the European standard and/or if it cannot be forwarded to the final recipient for whatever reason: an error message.
The filing party will then receive a forwarding acknowledgement sheet, which simply proves that the invoice has been submitted to the competent administrative authority.
Note: the invoice will be forwarded to the government administration department in question only once it has been validated.
Mandatory documents
In the case of a procedure without authentication, it is mandatory to attach the order form.
In addition and whatever the procedure used, the economic operator may attach to their application :
- plans;
- timesheets;
- other documents that explain the content of the invoice; or
- any other document that they consider appropriate.
Attachments can only be submitted in PDF format and cannot exceed a maximum size of 15 MB.
Financial aid
As part of the introduction of the requirement to submit electronic invoices for B2G (Business-to-Government) transactions, small and very small enterprises may be entitled, under certain conditions, to:
- financial aid for digitalisation under the SME Packages - Digital scheme; and
- personalised assistance:
- from the House of Entrepreneurship;
- from the eHandwierk services at the Chamber of Skilled Trades and Crafts.
