Peppol & Dokapi: E-Invoicing Ready Out of the Box

Diagram of the Peppol network with interconnected Access Points

What Peppol actually changes

As of 2026, every B2B invoice between Belgian taxable persons must travel through the Peppol network in UBL format. For many companies, it's the first time they're required to adopt a standardized exchange protocol.

Peppol is not an email channel with a PDF attached. It is a network of Access Points where each participant is identifiable (via their company number) and where documents travel in a structured, signed, timestamped format (UBL 2.1). The buyer no longer receives an attachment to retype: they receive data that flows straight into their accounting software.

Sending: a single checkbox

On every finalized sales invoice, a "Send via Peppol" button appears if the recipient is identified on the network. Behind the scenes, we generate compliant UBL, hand it to Dokapi, which forwards it to the recipient's Access Point, and we store the delivery receipt on the invoice. If Peppol is unreachable, we retry automatically — no user intervention needed.

Ingestion: the real surprise

The most impressive part is receiving. Every inbound Peppol document lands in Espero-Soft as a pre-filled purchase invoice: supplier matched via their company number, VAT lines extracted, totals checked. The user just validates — or corrects if they want to enrich the record.

No more retyping from a PDF. No more amount typos.

Admin page: inspect and replay

We also shipped a dedicated admin page listing all inbound Peppol documents, their processing status and any errors. A "Replay" button re-runs the ingestion of a document if something went wrong. Everything is auditable, everything is reproducible.

Security and traceability

Every inbound or outbound document keeps:

  • its unique Peppol identifier (UUID);
  • the hash of the original UBL file;
  • issuance and reception timestamps;
  • the Access Point signature from Dokapi.

In case of an audit, the history can be reconstructed to the minute.

Why Dokapi?

Dokapi is a Peppol-certified Access Point, operated in Belgium. Two reasons for us: data sovereignty (documents never leave the EU) and support availability (we have a technical contact for edge cases).

Enabling Peppol on your account

Activation takes under ten minutes: enter your Belgian company number (BCE/KBO) in invoicing settings, accept the Peppol registration terms via Dokapi, and confirm that you are published in the directory. From that point on, your outbound invoices can be sent via Peppol, and inbound invoices start landing in your purchase journal.
