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 — or you're just starting out as a freelancer and looking for the best option for your new business.
In this article, we compare the most widely used e-invoicing software for Peppol in Belgium, based on what truly matters for freelancers and small businesses: price, ease of use, and features.
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:
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.
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.
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. This protects you against invoice fraud — a real risk now that e-invoicing is mandatory.
💡 Tip: read here how to register on the Peppol network.
Starting out as a self-employed person in Belgium comes with costs (KBO registration, first social contributions, and so on) — not to mention taxes.
Fortunately, free e-invoicing software exists (or free versions of paid tools) that let you send and receive unlimited Peppol invoices with no cap.
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.
To save you the search, here's an overview of the 7 best e-invoicing tools in Belgium.
💡 Tip: check our comparison table to see at a glance which tools offer a free version.
Accountable is the best choice for freelancers who want everything in one place. The software combines Peppol invoicing with bookkeeping (tracking income and expenses), VAT returns, tax returns, client listings, social contributions, and even a free business current account.
Best for: sole traders, secondary-occupation freelancers, small limited companies, and freelancers.
What you get:
Price: free (unlimited Peppol, limited business expenses and bank accounts); paid plans from €1.50/month for starters, €9.90/month for other freelancers.
Downside: less suitable if you also need a full CRM or project management tool.
Billit is built around exchanging and processing invoices, and integrates well with accounting packages.
Best for: businesses that think invoicing-first, with their own accountant.
What you get:
Price: per document (invoice, credit note, receipt). At high volumes this can get expensive — check your expected number of documents per month before subscribing.
Downside: no VAT return or tax support. As a freelancer, you'll need a separate tool or accountant alongside it.
Teamleader Focus is a comprehensive business tool with Peppol functionality. If you manage lots of clients, track projects, and convert quotes into invoices, this is a powerful option. Teamleader One is the smaller sibling, letting you create and send quotes and invoices via Peppol.
Best for:
What you get:
Price: from €99/year (Teamleader One) to higher rates for Focus. No free version.
Downside: overkill for the average freelancer or sole trader who doesn't need a CRM. No support for Belgian VAT returns or tax returns.
Dexxter is accounting software for sole traders that also lets you send and receive Peppol e-invoices.
Best for: starters and secondary-occupation freelancers (sole traders) who want to manage their own bookkeeping.
What you get:
Price: paid subscription, from €180/year. No free version.
Downside: not suitable for limited companies, which can be restrictive as your business grows.
Yuki is primarily an accounting platform for accountancy firms. If your accountant uses Yuki, it's a logical choice for collaboration. Peppol is supported.
Best for: business owners who handle everything through their accountant.
Price: via subscription, typically through your accountant's firm.
Downside: the interface is dated and not intuitive if you want to work independently. Not built for freelancers managing their own bookkeeping.
With Onfact you can quickly create and send quotes and invoices via Peppol.
Best for: freelancers who simply want to send invoices, with no extra features.
Price: paid subscription, from €15/month.
Downside: no VAT return, no bookkeeping module, no tax support. You'll always need something else alongside it.
Lucy is a Belgian platform focused entirely on e-invoicing via Peppol. You receive and send invoices, manage a digital inbox, and forward documents to your accountant or accounting package.
Best for: business owners who work with an accountant and have a separate accounting tool.
What you get:
Price: paid subscription, from €4/month to €15/month depending on your needs.
Downside: no VAT return, no expense tracking, no tax support. As a freelancer, you'll always need a separate accounting tool alongside it.
If you're a freelancer or small business owner who wants to manage your bookkeeping (at least partially) yourself, Accountable is the most complete choice.
Not just because Peppol is fully and freely built in, but because you can also handle your VAT return, business expenses, and tax return all in one place — four things you'd otherwise need four separate tools for.
If you prefer working with an accountancy firm and just want invoices to come in correctly, Billit or Yuki may be a better fit.
If you're an SME with multiple staff members, projects, and client management needs, Teamleader Focus is worth considering — though it's more expensive and not an all-in-one for tax matters.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful…my accountant and tax advisor are good, but never so comprehensive and accurate. Combined with the AI I never feel alone with Accountable

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answer to most of the basic questions, specific scenarios need counsel from a human which your team performs beautifully.
