As a self-employed person, whether you are a sole trader or run a company, you can choose from plenty of accounting software. That is great, but it does not make choosing any easier. Should the tool connect to your bank account? Prepare your VAT return? Send Peppol invoices? And do you need an accountant, or would you rather do everything yourself?

On this page we set out the key criteria and compare four tools that self-employed people often consider: Accountable, Dexxter, Billit and Yuki.

An honest note upfront: Accountable is our own app. We therefore compare on points you can check yourself, and we also tell you when another tool is a better fit.

What should you look for when choosing accounting software?

Every self-employed person and every business has its own needs. That is why there is no single answer to the question "what is the best accounting software?". These six questions will get you well on your way:

1. Do you want to do your bookkeeping yourself, or with an accountant?

If you are a sole trader with fairly simple bookkeeping, you can in principle handle it yourself with the right software. If you have a company, working with an accountant is usually advisable.

Some tools are built for self-employed people who go it alone, others for accounting firms. That determines whether the interface and features suit you.

2. Can you connect your bank account?

A bank connection pulls in your transactions automatically, so you do not have to enter them by hand. Check how many accounts you can connect. Bonus points if you can also open a business account in the same app.

3. Does the tool help you file your VAT return and tax return?

Many tools stop at creating invoices and uploading business expenses. As a self-employed person, you also have to deal with your VAT return, your social contributions and your tax return. Accounting software that integrates all of this saves you extra subscriptions or a higher bill from your accountant.

4. Is e-invoicing via Peppol included?

Since the start of 2026, Peppol has been mandatory for VAT-registered self-employed people who invoice other businesses. It is therefore essential that the tool you choose supports e-invoicing via the Peppol network, preferably with no limit on the number of invoices.

💡Read more about the differences between Peppol tools in our comparison of the best e-invoicing software for Peppol.

5. How easy is it to work with your accountant in the software?

If you work with an accountant or bookkeeper, you want to be able to give them access or export your data to their own software.

6. What does it really cost?

Do not look only at the free trial or the entry price. Check whether there is a free version, whether you pay per document, and which features are only included in a more expensive plan. That way you avoid surprises later.

Think about the future of your business too: you may be self-employed on the side now and a certain tool suits that well, but if your business takes off, the move to full-time self-employment or a company can come quickly. Choose accounting software that grows with you.

1. Accountable: everything in one app for the self-employed

Accountable combines Peppol invoicing, bookkeeping, VAT returns, help with your tax return, the calculation of your social contributions and a free business account in a single app.

You can see at any moment how much tax, social contributions and VAT you have to pay, and when. An AI Tax Advisor answers questions about your tax situation, including outside office hours. Your accountant gets free access to your data, or can export your records to their own software via Accountable for Accountants.

The free plan includes unlimited Peppol invoicing and a 100% free business account. Paid plans start from €9.90 per month and offer more features, such as filing your tax returns through the app, a tax guarantee of up to €10,000 and legal expenses insurance.

The tool suits sole traders on the side and in their main occupation (including student entrepreneurs), as well as small companies.

Accountable is less suitable if you also need a full CRM or project management tool, or an integration with your web shop (e.g. Shopify).

2. Dexxter: simple bookkeeping for sole traders

Dexxter is accounting software for sole traders, with Peppol e-invoicing, VAT returns and filing reminders.

It is a good choice for starters, side-business owners and student entrepreneurs who want to do their own bookkeeping and prefer a clear annual price (from €220). There is no free version and the software is not suitable for companies, which can be limiting if your business grows.

3. Billit: invoicing first

Billit is built around exchanging and processing invoices and integrates well with accounting firms. Handy if you already have an accountant and mainly want to streamline your invoices.

You will still need a separate tool or an accountant for your VAT return and taxes. Because you pay per document, it is worth working out your expected volume.

4. Yuki: built for working with your accountant

Yuki is primarily an accounting platform for accountancy firms. If your accountant already works with Yuki, it is a logical choice. If you want to take your bookkeeping into your own hands, you get no help with your VAT or tax return: your accountant handles those obligations.

Which accounting software should you choose in 2026?

  • You want to do your own bookkeeping, with banking, VAT and taxes in one app: Accountable is the most complete choice.
  • You are a sole trader and simply want a straightforward programme with a fixed annual price: Dexxter is a solid option.
  • You have an accountant and mainly want to process your invoices: Billit is a good fit.
  • Your accountant already works with Yuki: stay with Yuki.

Frequently asked questions (FAQ)

What is the best accounting software for a self-employed person in Belgium?

It depends on your situation. If you want to manage everything yourself (bookkeeping, banking, VAT and taxes), an all-in-one app such as Accountable is the most complete choice. If you work entirely through an accountant, what matters most is that you both use the same software.

Can I do my own accounting as a sole trader in Belgium?

Yes, in principle. A sole trader usually has fairly simple bookkeeping and is not required to work with an accountant. Good software, such as Accountable, follows the tax rules for you and reminds you of your deadlines. We are nevertheless convinced that an accountant adds value, and we recommend getting support if you are in doubt or need personalised tax advice.

Is accounting software tax deductible?

Yes, the costs are business expenses. For e-invoicing software (including Accountable), you can even deduct 120% of the costs until 2027.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful. 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 answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
