Sending and receiving via Peppol, alongside your software.

Your invoices come in wherever you are, on your laptop or your phone. No more full folders and no pile waiting until you find the time.
We see those documents arrive as soon as you send them through. If something is missing or does not add up, we ask about it as soon as possible, not months later when you have long forgotten what it was about.
Figures are only useful if you see them in time. That way you know where you stand at any point in the year, not just after the close.
This is how your bookkeeping works at FinexpertWe work with both, because they solve different problems. Which one suits you depends on how you invoice today and which software you already use.
Yuki brings documents, bookkeeping, communication and financial insight together. You submit receipts digitally, follow your figures and keep questions attached to the right document.

Lucy sends and receives Peppol invoices independently of your accounting package. You can keep your existing way of working and still set up a simple, controlled invoice flow.
Not sure which one suits you? Get in touch and we will look together at which of the two simplifies your work most.
Peppol is a European network along which invoices travel directly from one accounting package to another. Not a pdf in a mailbox, but a structured file that your client's software can read straight away.
Since 1 January 2026 this is mandatory for every Belgian VAT-registered business that invoices other businesses. Towards public authorities the rule has applied for longer. If you work exclusively for private customers, it does not apply to your outgoing invoices.
The tolerance period of early 2026 has now passed. Anyone not yet compliant risks a fine of up to 5,000 euros.
Finexpert arranges your registration, checks your invoice details and tests with you whether sending and receiving work as they should.
Before we start, we agree clearly on documents, contact moments and responsibilities.
Then we first get you in order. We register you on the network, check that your invoices contain the right data and test together whether sending and receiving work. You do not have to figure it out yourself.
No. We look at how you invoice today, which software you use and how much you want to follow up yourself. Then we suggest one.
Not necessarily. Lucy works alongside your existing software and forwards your invoices to the bookkeeping. If Yuki fits better, we first look at which data we can take over.
With Yuki you track your documents, outstanding invoices and results digitally. What exactly you see, we agree in advance.
Absolutely. The software takes over work, not people. For questions about your documents, your figures or practical arrangements, you simply call your account manager.
We look at how you invoice today and how you submit documents. Then we set up together the way of working that fits your business.
