Submitting purchase invoices by email

How to submit purchase invoices by email to eConnect for automatic conversion and delivery.

Do you receive invoices by email or post? By forwarding them to your personal eConnect email address, they are automatically processed and delivered to your accounting software. It doesn't matter whether it's a PDF, image or XML file, eConnect processes everything.

Your personal email address

Once your organization is activated on the platform, you receive your own email address for purchase invoices:

<chamber-of-commerce-number>@inkoopfacturen.econnect.eu

This address is available immediately; you don't need to request or activate it separately. The default settings are not always aligned with your specific wishes, so always check that the address is properly configured, or create a new address via the Email Receiver where you can set up the settings exactly to your liking.

Custom address per supplier

Besides the standard KVK address, you can create a specific email address per supplier via the Email Receiver. The platform generates a unique address on the domain trust.econnect.eu with a random sequence of characters, for example:

[email protected]

Per address you determine which domain or email address may submit, which document type is created, and whether XML invoices are automatically forwarded. This offers more control than the standard KVK address and is available from the Basic subscription.

If you use the PSB (Procurement Service Bus), you can also receive invoices via email for processing. The extended Email Receiver functionality (whitelist management, classification, administration detection) is not yet available there, but basic processing of email attachments works.

How does it work?

When you send an email with an invoice attachment to your purchase invoices address, the following happens:

  1. Classification: the system checks each attachment and automatically determines whether it is an invoice, packing slip, attachment or other document.
  2. Processing: invoices are converted into a validated e-invoice. PDF invoices go through the IDR (Intelligent Document Recogniser) for OCR recognition. XML invoices are validated directly.
  3. Attachment linking: other documents in the same email (specifications, packing slips) are automatically attached to the invoice.
  4. Delivery: the processed invoice appears in your Inbox and is automatically forwarded to your linked accounting software.

Most invoices are processed within a few minutes. Read more about processing times.

Supported formats and limits

eConnect processes PDFs, XML invoices (all e-invoice formats), images (JPEG, PNG, BMP) and hybrid formats like ZUGFeRD/Factur-X. The maximum email size is 35 MB with a maximum of 50 attachments. Always send one invoice per file.

For a complete overview of all requirements and limits, see requirements for submitting invoices.

Email forwarding

You can also forward emails with invoices from your own mailbox. Keep the following in mind:

  • Use the forward function of your email client, not the redirect function.
  • Exclude the domains everbinding.nl and econnect.eu from automatic forwarding to prevent loops.
  • Only forward emails that actually contain an invoice attachment.
Error messages

If something goes wrong during submission, you will receive an error message by email at the address from which you sent the invoice. Common causes include an oversized file, an unreadable PDF, or an XML file that does not meet the required standard.
