What is Peppol?
Peppol (Pan-European Public Procurement Online) is the international standard for electronic invoicing (e-invoicing) and ordering. The secure Peppol network enables electronic messages to be exchanged between organisations worldwide in a standardised, secure, and efficient way.
Why do I need this connection?
An increasing number of (semi-)government bodies and organisations set requirements for how invoices must be submitted. Electronic invoicing via the Peppol network is often mandatory. With the connection between MICE and Peppol, you can easily comply with these requirements without changing your way of working.
By sending invoices directly from MICE via the Peppol network, you avoid extra steps such as manual exports, email attachments, or separate invoicing systems. This makes the process efficient and clear, and reduces the risk of errors.
How do I activate the connection?
All you need to do is activate the Peppol integration in MICE. The technical work has already been taken care of, so you do not need to create a separate Peppol account or choose an external partner (e.g. Peppol Service Provider).
Follow these steps to activate the Peppol integration:
Go to ‘Setup’ (from the main menu).
Click ‘Integrations > Links' in the setup menu.
Navigate to the Peppol section and click the ‘Connect’ button.
A window with information will appear. Read this carefully and then click ‘Confirm’ to activate the integration.✅
Points of attention⚠️
To ensure that invoices from MICE are successfully sent via the Peppol network, it is crucial that certain details (see table below) are entered correctly and in the required format in MICE.
Please note: The Peppol network is very strict. Special characters such as dots in a VAT number often cause a registration or invoice to be rejected.
Data | Format instruction | Example |
Country | Use the two-letter country code (ISO country code). | DE |
Chamber of Commerce number | Enter only the 8 digits, without spaces or dots. | 12345678 |
VAT number | Start with the country code, followed by the number without spaces or punctuation. | DE123456789 |
Check your billing details
It is important that the country, Chamber of Commerce number and VAT number are entered correctly in your billing details (as shown in the format in the table above).
Navigate to Setup > Settings > Billing (or click here).
Check client details
It is important that the country, Chamber of Commerce number and VAT number are entered correctly in the client details of the organisation receiving your invoice (as shown in the table above).
Navigate to the event > Click on the three dots to the right of the organisation > Edit customer.
Sending an invoice from MICE via the Peppol network
In MICE, it is very easy to send an invoice via the Peppol network. When sending the invoice, click the “via Peppol” button and the rest will be processed automatically.
Please note: Before submitting an invoice via the Peppol network, carefully check that the billing details for your organisation and the client have been entered in the correct format. See the points of attention above
Follow these steps to send an existing invoice via the Peppol network:
Open in MICE the invoice you want to send via Peppol.
Click the ‘Send’ button at the top of the invoice (do not worry, the invoice will not be sent yet).
Click the ‘via Peppol’ button at the bottom of the window.
The invoice has been sent via the Peppol network.✅
Confirmation of sending
To the right of the invoice you will find the ‘history’, which contains all actions related to the invoice. This shows that the invoice has been sent via Peppol.
Sending failed?
If the identification or registration of an invoice with Peppol fails (for example due to incorrect company details), you will almost immediately see an error message on the screen. If necessary, take a screenshot of the message and send it via chat to the MICE support team.
📅 Tolerance period in Belgium
Belgium will introduce mandatory e-invoicing for Business-to-Business (B2B) transactions as of 1 January 2026. To allow everyone sufficient time for a smooth transition, as certain practical issues may arise, the Belgian government has introduced a tolerance period of three months (until 31 March 2026 inclusive). During this period, no sanctions will be imposed for infringements resulting from the new e-invoicing obligation, provided that you can demonstrate that you have worked in a timely and reasonable manner on implementing e-invoicing. This means that technical or system-related challenges in the initial phase will not immediately result in a fine, as long as you are making progress towards full Peppol compliance.

FAQ
Can I also receive invoices from Peppol in MICE?
No. You can receive invoices from Peppol in only one tool, as you manage incoming invoices in one central place. The most obvious tool for this is your accounting software. To prevent issues, we have blocked the option to receive invoices in MICE. If you need more information about receiving invoices via Peppol, we recommend contacting the support department of your accounting software.
Do I need my own Peppol account?
No, as a MICE user you do not need to have your own Peppol account. Once you activate the connection in MICE, you can immediately send invoices via the network to your clients.
Does my client need a Peppol account?
Yes. The recipient of the invoice (your client) must be registered on the Peppol network in order to receive the invoice in this way.
Do I need to be connected to a Peppol Service Provider?
No, you do not need to engage an external partner or provider. MICE Operations has already arranged this for you. We use a certified provider (4CEE B.V.) to connect your account directly to the Peppol network.
