Does Your Belgian Shop Have to Receive E-Invoices Too?

If your Belgian shop has to send structured e-invoices, its suppliers have to send them to you. Belgium's business-to-business e-invoicing obligation has applied since 1 January 2026 and it is symmetrical — it describes invoices between businesses, not invoices leaving your business. So the shop needs two things: to be reachable on the Peppol network, which means its enterprise number published under identifier scheme 0208, and to be able to handle what arrives, which means a structured XML document rather than a PDF. Those are different jobs, and doing one does not do the other.

This page is for the owner or store manager of a Belgian shop that already understands the sending side. If you have not settled that yet, whether your Belgian shop has to send e-invoices at all is the page to read first; this one is its other half.

Does my Belgian business have to receive e-invoices?

In practice, yes — and the reason is worth understanding rather than memorising.

The Belgian obligation is written about supplies between businesses. Every invoice has two parties, so the same rule that makes you issue a structured invoice to a business customer makes your suppliers issue structured invoices to you. The sending duty is theirs. The consequence lands on you, because an invoice that cannot be delivered is an invoice that does not reach your books, and the payment terms keep running while everybody works out why.

There is no separate "receiving registration deadline" to diarise. There is a network that either resolves your company or does not, and from 1 January 2026 a growing share of your suppliers are obliged to try.

A PDF by email is not the fallback. Belgium does not accept one as a business-to-business invoice — the point is made in full on the sending side of this rule and it cuts the same way inbound. A supplier who emails you a PDF has not complied, and your accepting it does not repair their position or yours.

What does "reachable" actually mean?

It means one record exists, in one place, saying that documents for your enterprise number go to your provider.

Peppol delivers on a four-corner model: your supplier's access point has to discover where to send before it can send. That discovery is a lookup of your participant identifier in a service metadata publisher — an SMP, the network's address book. If your company has a record there, the lookup resolves and the document is delivered. If it does not, the send fails at the first step, and the supplier sees an error rather than you seeing an invoice.

Two specifics decide whether that lookup works.

The identifier is your enterprise number, under scheme 0208. Not the VAT number, and not a company name. Registering a Belgian participant under the wrong scheme is a breach of the Belgian rule rather than a matter of taste, and why scheme 0208 is not optional covers the check digit and what the failure looks like at lookup.

Nothing registers you by default any more. Until the end of 2025 Belgian companies were reachable more or less automatically, because BOSA pre-registered them. That stopped: Hermes was decommissioned on 31 December 2025, so a Belgian company with no service provider is now genuinely unreachable. This is the single most common reason a Belgian business believes it is receiving e-invoices and is not.

Who registers my shop, and do I already have it?

Check before you buy anything, because you may already be done.

If you run one of our storefront apps, you are registered. Setting up the WooCommerce plugin or the Wix app registers your store as a Peppol participant as part of set-up — the same registration serves sending and receiving, because they are two capabilities on one participant record rather than two separate arrangements. Both apps are free for the first fifty e-invoices a month. If your shop is on either platform, the receiving half of the Belgian rule is already handled, and the useful next step is to confirm your enterprise number is the one on the record.

If you do not run a storefront app, registration is the product you want on its own. A business can be reachable on Peppol without having any shop software at all — that is GoRoute's Peppol registration service, at $29 a month, which publishes your company in our SMP and gives you a live check proving the lookup resolves. It is the right answer for a wholesaler, a service business or a company whose selling happens somewhere other than a website.

It is the wrong answer if you are already installing the WooCommerce or Wix app, and we would rather say so here than sell you the same capability twice. Who registers you on Peppol sets out the general division of labour between you, your provider and the Peppol authority, in whatever country you are in.

What arrives, and what do I do with it?

A structured XML document — Peppol BIS Billing 3.0, which is UBL 2.1 aligned to the European semantic standard EN 16931.

This is where the second job starts, and where a shop that ticked the registration box can still end up stuck. The arriving file is built to be read by software. Opening it in a browser is technically possible and practically useless, and a business that receives forty of them a month with no handling arrangement has swapped a manageable pile of PDFs for an unmanageable pile of XML.

So what you want from your access point is both halves at once:

• The structured document, delivered wherever your accounting system can consume it, so the invoice becomes a payable without anybody retyping it. Retyping a structured invoice by hand is the one outcome that makes the whole regime a cost rather than a saving.
• A human-readable rendering of the same document, for whoever approves the payment. The legal invoice is the structured file; the rendering is a view of it, and it is what your purchasing manager should actually be looking at.
• A validation result you can see. A document that fails the Belgian rules should be visible as a failure with a reason, not a silence.
• The document kept. Retention is the received file, not a printout of it.

GoRoute is itself the certified Peppol access point — POP000991 — so the lookup record, the delivery, the validation and the acknowledgement are one service with one place to ask when a document has not turned up. That matters more inbound than outbound: when your own invoice fails you find out from your own system, but when a supplier's invoice fails you often find out from a reminder letter.

Who answers my supplier, and what do they hear?

Your access point answers, automatically, and it answers a narrower question than people assume.

Peppol acknowledgement is technical. When the document reaches your provider and validates, the sender's provider is told it arrived. Nobody in your business has to do anything for that to happen, which is the design working correctly — the network is telling the supplier that delivery succeeded.

What that answer does not say is that you accept the invoice. Approval, query and dispute remain ordinary commercial conversations conducted the way they always were. A delivered invoice you disagree with is a delivered invoice you disagree with, and the correction travels as a credit note from the supplier rather than as a rejection from you.

What if my supplier is the one who is not ready?

That is now the likelier problem, and it is a conversation rather than a technical task.

Your side is a lookup record, done once. Your suppliers' side is their own software, their own provider and their own timetable, and a supplier who has not started will not be fixed by anything you configure. What you can do is remove every excuse on your own side: be reachable, publish your enterprise number on your purchase orders and remittance details, and tell suppliers who email PDFs that you can receive properly and that Belgium does not accept the PDF.

How a supplier sets up their own sending is outside this page deliberately. It depends on their platform, and pointing them at the sending-side guide or Belgium's country page is more useful than anything we could generalise here.

What this page does not cover

Penalty amounts. What non-compliance costs in Belgium has its own page, and the figures are not restated here, because a number quoted second-hand in the wrong place is how a wrong number spreads.

Any country but Belgium. The receiving position differs elsewhere — Germany's obligation to receive arrived on a different date and accepts a different set of formats. Do not read the Belgian answer across.

How your supplier's own software is set up. Their platform, their provider, their decision.

What to do next

Look up your own enterprise number before a supplier does it for you. Either it resolves or it does not, and that single check tells you whether the receiving side of the Belgian rule is already handled or has never been started.

If your shop is on WooCommerce or Wix, install the app and the registration comes with it: the WordPress.org plugin listing and the Wix App Market listing. If you want to be reachable without a storefront app, that is Peppol registration at $29 a month. Recorded walkthroughs are on tutorials, the document types, statuses and identifier formats are in the developer documentation, and the Belgian regime in full is on our Belgium page.
