Accountable lets you create, send, and receive invoices via Peppol, the European e-invoicing network, directly from the app. Whether you need to comply with Belgium's B2B e-invoicing rules or simply want a professional invoicing tool, this guide covers everything you need to get started.
Below you will find how to activate Peppol, send and receive invoices, explore the invoicing features, and choose the right plan.
1. What is Peppol?
Peppol (Pan-European Public Procurement Online) is a secure network that lets businesses send and receive structured e-invoices in a standardised format.
In Belgium:
Peppol was already mandatory for invoices to public sector clients.
Since January 2026, it is mandatory for B2B invoicing between Belgian companies.
Peppol is not an email or a PDF. It is a machine-readable document sent through a certified access point. Using Peppol helps ensure:
Legal compliance
Faster processing
Fewer errors and disputes
2. How do you activate Peppol in Accountable?
Accountable is a certified Peppol access point, which means you can send and receive Peppol invoices directly from the app, without any third-party tools.
There are a few steps to complete first:
You need to verify your identity and confirm your company details. This is a legal requirement to prevent fraud on the Peppol network.
In Accountable, go to More > Settings > Peppol and follow the steps:
Fill in your enterprise number (if not already provided)
Upload a valid proof of identity (eID or passport)
Wait for confirmation
Once verified, your business is officially registered on the Peppol network.
For more detail on the registration process, see how to register on the Peppol network.
Did you know that since Accountable is a certified Peppol access point, your subscription fee is 120% deductible ? It will be the case until end of 2027.
3. How do you send an invoice via Peppol?
Once your registration is approved, sending a Peppol invoice works almost the same way as sending a regular invoice:
Create an invoice as usual in Accountable.
Select a client that has a known Peppol address.
Accountable will automatically detect if this client can receive Peppol invoices.
Choose "Send via Peppol" instead of email or PDF.
The invoice is sent directly to their accounting system through the network.

3a. How do you send imported invoices via Peppol?
If you already have invoices in PDF form, you can also import them into Accountable and send them via Peppol. Here is how it works:
Go to Revenue in Accountable.
Click Import invoice to bring in your own invoice file (PDF).
Fill in the required details (client, amounts, invoice date, etc.), then mark the invoice as "Not sent".
When you are ready, choose "Save and prepare to send" and make sure "Send the invoice via Peppol" is selected.
Make sure your client is registered on the Peppol network for the Peppol option to work.
This lets you continue using your existing invoices, even if they were not created in Accountable, while still benefiting from Peppol delivery.

4. How do you receive an invoice via Peppol?
Once your business is registered, you can also receive structured e-invoices from suppliers that use Peppol.
How it works in Accountable:
The supplier sends the invoice through the Peppol network using your registered enterprise number.
The invoice arrives directly in Accountable and is added to your expenses. A small Peppol logo appears next to it.
You receive an email notification confirming that an invoice arrived via Peppol.
This removes the need to forward emails or scan PDFs. The invoice data is already structured, making it straightforward to process or export.
5. What can you do with Accountable's invoicing tools?
Even if you are not using Accountable for bookkeeping or taxes, the invoicing features are designed to be simple and complete:
Create and send professional invoices
Fully customise layout (logo, notes, terms and conditions)
Send invoices via email, Peppol, or PDF download
Track payment status and send reminders
Issue credit notes when needed
Automate recurring invoices
Work in multiple languages and currencies
You can also export your invoices for your accountant, or download them in bulk.
6. What else can you do in Accountable?
You can start with invoicing only. When you are ready to do more, Accountable also lets you:
Connect your bank account to track payments
Scan and manage business expenses
Follow your VAT and tax situation in real time
Prepare and submit your VAT returns
Export all your data or collaborate with your accountant
You can enable these features whenever you are ready, with no obligation.
