BILLY is the #1 solution for freelancers and self-employed professionals in Belgium, designed to help them create and manage their business smoothly and without mistakes. It brings together all the advanced features they need, such as accounting support, human assistance, intuitive mobile apps, compliant invoicing, Peppol-ready billing, photo-based expense reporting and much more.

Because BILLY develops its own application in-house, the solution is fully tailored to the real needs of self-employed professionals. When looking for a partner for Peppol, BILLY wanted a solution that was reliable and easy to integrate.

On the recommendation of developers, BILLY discovered Digiteal. The choice was straightforward: Digiteal’s expertise and support allowed BILLY to offer fully integrated Peppol e-invoicing to its customers.

Challenges

BILLY needed to prepare freelancers for mandatory B2B e-invoicing while ensuring simplicity from day one.

The team identified four main challenges:

1Finding a Peppol Access Point with a clear offer (both technically and commercially)

2Making sure the solution was easy to integrate with BILLY’s own platform

3Partnering with a local provider who truly understands the Belgian context and requirements

4Ensuring transparent and predictable pricing for long-term sustainability.

Solution

Digiteal stood out immediately thanks to its clarity and hands-on support.

Developer-to-developer integration
BILLY’s technical team particularly appreciated that discussions with Digiteal were concrete, with a true developer vocabulary (API, payloads, implementation…). This made the onboarding straightforward and efficient.
Training and guidance
Digiteal provided a clear introduction that helped BILLY to understand what to implement and how to use it effectively.
Easy API integration
The Digiteal Peppol API was quickly integrated into BILLY’s solution. Self-employed professionals now have the possibility to send and receive compliant invoices through Peppol directly from their familiar BILLY environment.
