Why Do You Need This Module?

The Challenge

Only the invoice or debit note itself as PDF attachment will be included when Odoo sends via PEPPOL. If additional documents are needed, they must be sent separately via email or other channels.

The Problem

Workflow fragmentation, manual processes across multiple channels, compliance gaps from missing documentation, and customer confusion from correlating documents from different sources.

The Solution

This module enables sending and receiving multiple attachments through PEPPOL. All supporting documents are embedded directly in the UBL XML according to BIS Billing 3.0 standards.

Key Features

Outbound Documents

  • Simple Checkbox Interface: Mark and upload attachments to send via PEPPOL
  • Integrated Send Wizard: Manage attachments directly in the invoice send dialog
  • Automatic Embedding: Attachments are Base64-encoded into UBL XML
  • File Validation: Real-time size checks with configurable maximum file size
  • Multiple Files: Send multiple supporting documents as needed

Inbound Documents

  • Automatic Import: Attachments from received invoices are imported automatically
  • Format Support: Handles PDF, JPEG, PNG, XLSX, ODS, CSV
  • Seamless Attachment: Files are automatically linked to invoice records
  • Standards Compliant: Follows PEPPOL BIS Billing 3.0 specifications

Bidirectional

Not only handle sending, this module supports both sending and receiving attachments through PEPPOL network.

Standards Compliant

Fully compliant with PEPPOL BIS Billing 3.0 and UBL 2.1 standards. Works seamlessly with any PEPPOL access point.

Automatic

Just add attachments at the sending dialog. Receiving attachments is completely automatic. No complex configuration required.

Installation & Configuration

1

Prerequisites

Ensure PEPPOL is already installed and configured: Accounting → Configuration → PEPPOL Electronic Document Invoicing

2

Install the Module

Go to Apps, search for "PEPPOL with multiple attachments", and click Install
✔

Done - Start Sending Attachments!

No additional configuration needed. Create an invoice, add attachments, and select them for PEPPOL transmission.
Pro Tip: The 2MB file size limit is a best practice for PEPPOL network performance. We recommend consulting your PEPPOL access point provider if you need to send larger files.

Test Your PEPPOL Setup

After configuring PEPPOL Electronic Invoicing, you can verify the complete send/receive workflow by sending an e-invoice to your own company. This is an effective way to test both outbound transmission and inbound document reception, including the multi-attachment feature provided by this module.

Prerequisite: Your company must be registered as a PEPPOL Participant with a valid PEPPOL Endpoint ID (e.g., EAS 0208 for Belgian enterprises, EAS 9925 for Austrian enterprises). The PEPPOL registration must be completed and verified by Odoo before testing.
1

Create a Customer Partner for Your Own Company

Navigate to Contacts and create a new Partner representing your own company as a Customer. Configure the same PEPPOL Endpoint ID (Participant ID) that your company uses for receiving e-invoices via the PEPPOL network.

2

Create a Customer Invoice with Attachments

Go to Accounting → Customers → Invoices and create a new Customer Invoice for the Partner you just created. Confirm the invoice to post it.

3

Send via PEPPOL with Attachments

Click Send & Print and select PEPPOL as the sending method. In the send dialog, add the attachments you want for PEPPOL transmission. The e-invoice with embedded attachments will be sent through Odoo to the PEPPOL network.

4

Waiting

Waiting Odoo's cron job works and receiving e-invoice from PEPPOL network, by default the cron job will run every 4 hours, you can change the interval in the cron job settings at Settings → Technical → Scheduled Actions → PEPPOL: retrieve new documents.

✔

Test Complete - PEPPOL Workflow Verified!

Navigate to Accounting → Vendors → Bills. You should see the e-invoice you just sent, imported as a Vendor Bill with all attachments automatically linked. If the Vendor Bill contains all attachments you sent, your PEPPOL configuration is working correctly. Both outbound transmission and inbound document import with multi-attachment support are fully operational.

Frequently Asked Questions

Does this work with all PEPPOL access point providers?

Yes! This module follows the standard PEPPOL BIS Billing 3.0 specification and works with any compliant access point provider.

Are the attachments transferred through PEPPOL network?

Yes! This module enables Odoo to send attachments through PEPPOL network, which means all documents are transmitted via the PEPPOL infrastructure only.

Can I send multiple attachments with one invoice?

Yes, you can send as many attachments as needed in theory. All the attachments will be embedded in a single E-Invoice file. In practice, different PEPPOL access point providers have different limits. According to our experience, 10MB total is widely accepted.

What happens if my attachment is larger than the maximum file size limit?

The system will show a validation error and prevent sending until you reduce the file size or uncheck that attachment. You can configure the maximum file size in settings.

Will recipients without this module receive my attachments?

Yes! Attachments are embedded in the standard UBL XML. Any PEPPOL-compliant system can receive and process them (though they may need their own import functionality based on the PEPPOL specification).

Does this affect regular email invoice sending?

No, this only affects PEPPOL transmissions. Regular email sending in Odoo works as usual with standard attachment handling.

Can I receive multiple attachments within one invoice?

Yes! This module enables Odoo to receive multiple attachments within one invoice based on the PEPPOL specification. The attachments will be retrieved automatically and linked as attachments in Odoo.
