E-invoicing and Peppol: what really changes in your order-to-cash?

If you supply to multiple countries, chances are e-invoicing is coming your way. Belgium is making structured business-to-business e-invoicing mandatory from 2026, Germany is phasing it in, and at the European level it's heading the same way. Most of what's written about it is about VAT and accounting. What almost nobody covers is what it does to your chain. That's exactly where the work sits for a wholesaler. Note: this is a practical explanation, not tax advice. Have your accountant confirm the exact obligations and dates for your situation.
What e-invoicing is (and isn't)
Emailing a PDF is not e-invoicing. An e-invoice is an invoice as structured data, which your customer's system can read and process directly without anyone retyping. Peppol is the network these invoices are often exchanged over, a kind of universal plug between administrations.
The difference with a PDF is fundamental. A PDF is a picture a human reads. An e-invoice is data a system reads. That makes processing faster and more error-free, but it also sets harder requirements on what you send.
The real impact is upstream
Because an e-invoice is read directly, it has to be correct at line level. Article codes, quantities, prices, and VAT must be right, because there's no longer a person in between fixing a small mistake. An error you used to solve by phone now becomes a rejected invoice.
And that's exactly why this is a chain topic, not an accounting topic. An invoice is only as good as the order and the master data it comes from. If your article data is wrong, or your codes don't match the customer's, that now falls over mercilessly on the invoice side.
Getting your data right at the source
The temptation is to park e-invoicing as a small project at accounting: add a connector and done. That only works if your data is already right. If it isn't, you move the problem to the end of the chain, where it's more expensive to solve.
The durable approach is to get the invoice data right at the source: clean article and customer data, and order processing that captures the right codes and prices from the start. Then the correct e-invoice rolls out on its own, instead of you having to repair it afterwards.
Does this work with what we already have?
Yes. We connect to your existing ERP and accounting package, such as Business Central, SAP, Exact, and Odoo, and make the order-to-cash flow airtight: from order to packing slip to invoice, with the right data at every step.
You also don't have to wait until everything is perfect. We assess the current state of your data, determine the minimum to start, and improve the rest as it runs. So you're ready in time without grinding to a halt for half a year.
E-invoicing isn't an accounting chore, it's a chain topic. An e-invoice is only as good as the order and the data it comes from. Get your invoice data right at the source and you not only meet the new requirements, but process your whole order-to-cash faster and more error-free. Have your accountant confirm the exact dates for your markets.
Frequently asked questions
Is an emailed PDF invoice enough?
For the new obligations, usually not. They require a structured e-invoice that the recipient's system can read directly, often via the Peppol network. Have your accountant confirm what applies to your markets.
What if our article data isn't perfect?
Then this is exactly the moment to tackle it at the source. An e-invoice is read directly, so errors in codes or prices fall over mercilessly. We clean the data as we set up the order-to-cash flow.
How quickly can we be ready for this?
A focused engagement typically runs 4 to 8 weeks from strategy to go-live. We start with a short strategy phase to determine what comes first, so you comply in time without overturning everything at once.
