The 3 best e-invoicing services compared for 2026

The deadline of January 1, 2026 is approaching quickly. All Belgian companies must be able to send and receive electronic invoices via the Peppol network. For many entrepreneurs, the question arises: which e-invoicing software is the best choice for my company?

The offerings are overwhelming, and not every solution is equally suitable for Belgian SMEs. Some tools are too complex, others lack essential features, and yet others are unaffordable for smaller enterprises. In this comparison, we lay out the three best e-invoicing services for you, so that you can make an informed choice.

We look not only at features and prices, but especially at usability, reliability, and how well the software aligns with Belgian legislation. The best software is one that allows you to start today and be ready for 2026 tomorrow.

Why the right e-invoicing software is crucial for the deadline

The choice of e-invoicing software is not a minor matter. This is not just a tool you add on: it becomes the heart of your invoicing and payment process. A wrong choice can lead to time loss, frustration, and in the worst case, fines for not being compliant in time.

The right choice must not only be an affordable invoicing software but must also meet several critical requirements.

Firstly: full Peppol certification. Without correct connection to the Peppol network, you cannot send valid e-invoices. Always check whether the provider is a recognized Access Point Provider or collaborates with a certified party.

Secondly: seamless integration with your current workflow. If the new software does not connect with your accounting system or bank account, you’re creating more work instead of less. You want automation, not extra administrative steps. Look for solutions that connect directly with popular Belgian accounting packages.

Thirdly: support for multiple invoice formats. The reality is that in 2026, you will not only receive Peppol invoices. Foreign suppliers will still send PDFs, or paper invoices. Restaurants and parking garages will continue to use receipts, even after January. The best software can process all formats and automatically convert to the correct format, so you do not have to do manual work.

Fourthly: ease of use and speed. As an entrepreneur, you do not have time for complicated software that requires weeks of training. You want a solution that works intuitively and delivers results immediately. Time savings equate to cost savings, especially for SMEs where every minute counts.

Finally: reliable customer support in Dutch. When you have questions or experience technical problems, you want to be helped quickly by someone who understands the Belgian context. Software without good support is a risk you should not take.

The best e-invoicing services for SMEs in Belgium: our top 3

1. Cashfeed: AI solution for SME invoicing

Cashfeed positions itself as the most advanced and user-friendly e-invoicing solution for Belgian SMEs. The software combines artificial intelligence (AI) with full Peppol integration, which makes all the difference.

What makes Cashfeed unique is the complete automation of your invoicing workflow. While other solutions focus on sending e-invoices, Cashfeed goes further. The AI automatically finds all incoming invoices in your inbox, regardless of the format. PDF, XML via Peppol, or even scanned paper invoices and receipts: everything is recognized, processed, and prepared for approval.

The OCR technology of Cashfeed is market-leading. Even poorly scanned or rotated invoices are flawlessly read. Amounts, suppliers, due dates: everything is automatically extracted and placed in the correct field. This saves a tremendous amount of time and eliminates typos that can occur with manual input.

The payment process is equally simple: with one click you pay invoices, and the reconciliation (matching) with your bank account happens automatically. You no longer need to manually match or double-check. Cashfeed clearly shows which invoices have been paid, which are still outstanding, and where any issues lie.

For SMEs, the time savings are spectacular. Users report that they work five to ten times faster than before. Processing an invoice that previously took five minutes now takes only thirty seconds. For companies that process dozens of invoices per month, this saves hours.

The software starts in less than two minutes, without a credit card or complex installation. You can immediately start sending Peppol invoices and automating your incoming invoice management. The user interface is in Dutch, intuitive, and built with the Belgian user in mind.

Cashfeed integrates seamlessly with popular Belgian accounting packages and works perfectly with external accountants. Your accountant gains direct access to all documents and can approve, advise, or ask questions online. This eliminates the back-and-forth of sending documents and greatly improves collaboration.

The pricing is transparent and fair. There are no hidden costs, and you only pay for what you use. For SMEs and the self-employed, there is an affordable package that includes all essential features, including full Peppol connectivity.

2. Billit: a known choice

Billit is a well-established name in the Belgian market and is used by many entrepreneurs for invoicing and accounting. The software has been around for years and has built a solid reputation.

The strength of Billit lies in its wide functionality. It is not just e-invoicing software, but a complete invoicing and accounting package. You can create quotes, draft invoices, record expenses, and generate reports. For entrepreneurs who want everything in one tool, Billit offers a comprehensive solution.

Billit has recently added Peppol support to be ready for 2026. You can send e-invoices via the network and also receive them. The implementation is functional, although it mainly focuses on sending invoices and less on automatically processing incoming documents.

The user interface is clear and logically structured. If you are used to creating and sending invoices yourself, Billit offers a familiar workflow. The learning curve is reasonable: within a few hours you will be familiar with the software.

An advantage of Billit is the connection with various Belgian banks and accounting programs. You can import transactions and link invoices to payments. This saves time in administration and provides a better overview of your cash flow.

The prices of Billit are on average higher than some competitors, but you get more functionality. There are various packages available, from basic to premium, depending on the number of users and features you need.

A point of attention with Billit is that the focus is primarily on traditional invoicing workflows. The AI-driven automation and advanced OCR features offered by, for example, Cashfeed are limited. You will need to do more manual work when processing incoming invoices.

3. Dexter: focus on sole proprietors

Dexter specifically targets sole proprietors, freelancers, and very small businesses. The software is intentionally kept simple and meets basic needs without unnecessary bells and whistles.

The user experience of Dexter is pleasantly minimalist. You are not overloaded with features you do not need. Creating, sending invoices and a simple overview of payments: this is what Dexter excels at. For someone just starting or sending few invoices, this does not feel overwhelming.

Dexter has also implemented Peppol support for the upcoming obligation{
