Since the start of this year (2026), e-invoicing via Peppol has been mandatory for all VAT-liable Belgian self-employed people who invoice other businesses (B2B). You may already have a tool but wonder whether it’s the right choice \u2014 or you’re just starting out as a freelancer and looking for the best option for your new business.<\/strong><\/p>\n\n\n\n

What to look for when choosing Peppol software<\/h2>\n\n\n\n

There’s no one-size-fits-all answer when it comes to the best e-invoicing software for your business. Ask yourself these 3 questions before making a choice:<\/p>\n\n\n\n

1. Is Peppol registration included?<\/h3>\n\n\n\n

To send and receive Peppol invoices, you need to register on the Peppol network once. Opt for a tool that offers this registration for free.<\/strong><\/p>\n\n\n\n

Also pay attention to how the registration works. The best tools handle this through a KYC (Know Your Customer) process with identity verification via itsme or eID.<\/p>\n\n\n\n

That might sound like an extra step, but it’s actually an advantage: by verifying your identity, no one can register on the Peppol network in your name and send invoices as if they came from you.<\/strong> This protects you against invoice fraud \u2014 a real risk now that e-invoicing is mandatory.<\/p>\n\n\n\n

2. Is there a free version available?<\/h3>\n\n\n\n

Starting out as a self-employed person in Belgium comes with costs (KBO registration, first social contributions, and so on) \u2014 not to mention taxes.<\/p>\n\n\n\n

Fortunately, free e-invoicing software exists<\/strong> (or free versions of paid tools) that let you send and receive unlimited Peppol invoices with no cap.<\/strong><\/p>\n\n\n\n

3. Does the software do more than just invoicing?<\/h3>\n\n\n\n

Some tools let you send e-invoices via Peppol, and that’s it. But as a freelancer, you also need to handle VAT returns, business expenses, and your tax return. Software that integrates all of this saves you a significant amount of time and money on extra subscriptions.<\/p>\n\n\n\n
