PEPPOL with multiple attachments
Send and Receive Supporting Documents Through PEPPOL Network
Extend PEPPOL invoice and debit notes with supporting documents! This module enables Odoo to send and receive multiple attachments through the PEPPOL network, allowing you to send delivery notes, certificates, product specifications, and other supporting documents directly embedded in your PEPPOL invoices and debit notes according to BIS Billing 3.0 standards.
The Problem We Solve
Only the invoice or debit note itself as PDF attachment will be included, when Odoo sends invoice or debit note via PEPPOL. If additional documents are needed, there are several challenges:
- Workflow Fragmentation: Supporting documents must be sent separately via email or other channels
- Manual Processes: Staff waste time managing documents across multiple channels
- Compliance Gaps: Missing documentation can cause regulatory issues
- Customer Confusion: Recipients must correlate documents from different sources
- Incomplete Records: No automatic attachment of received supporting documents
- Professional Image: Fragmented communication appears unprofessional
Key Features
Outbound Documents
- Simple Checkbox Interface: Mark and upload attachments to send via PEPPOL. PEPPOL supports following file formats: PDF, JPEG, PNG, XLSX, ODS, CSV
- 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. You can configure the maximum file size in settings.
- Multiple Files: Send multiple supporting documents as needed
Inbound Documents
- Automatic Import: Attachments from received invoices or debit notes are imported automatically and linked as attachments in Odoo
- Format Support: Handles PDF, JPEG, PNG, XLSX, ODS, CSV, which are supported by PEPPOL
- Seamless Attachment: Files are automatically linked to invoice or debit note records
- Standards Compliant: Follows PEPPOL BIS Billing 3.0 specifications

Frequently Asked Questions
Q: Does this work with all PEPPOL access point providers?
A: Yes! This module follows the standard PEPPOL BIS Billing 3.0 specification and works with any compliant access point provider.
Q: Can I send multiple attachments with one invoice?
A: Yes, you can send as many attachments as needed in theory. All the attachments will be embedded in an E-Invoice file lonely. In practice, different PEPPOL access point providers have different limits on the size of the E-Invoice file. According to our experience, 10MB total will be widely accepted. We recommend you to consult your PEPPOL access point provider in your country if you need to send larger files.
Q: What happens if my attachment is larger than my maximum file size limit?
A: 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 by yourself.
Q: Will recipients without this module receive my attachments?
A: 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).
Q: Does this affect regular email invoice sending?
A: No, this only affects PEPPOL transmissions. Regular email sending in Odoo works as usual with standard attachment handling.
