The Claeys & Engels challenge: when complexity delays invoicing
For law firms, the focus is rightly on expertise and clients. But internal and external complexity often makes timely and accurate invoicing a challenge.
At Claeys & Engels, this led to a number of structural challenges:

The Claeys & Engels solution: AAA’s carefree combination
Claeys & Engels was not looking for extra internal staff, but for peace of mind, structure, and clarity. The solution came via AAA’s Combi-solution: managed services supported by smart software.
1. Managed Services: structure and ownership
AAA took active charge of the follow-up on invoicing and disputes. That meant:
- Human follow-up of outstanding and disputed invoices
- Correct prioritization: not automatically treating everything as a “dispute”
- Active communication and follow-up instead of stagnation
- Relieving the burden on lawyers and assistants
- Focus back on core business: legal services
Ownership was restored to a process that had been neglected for years.
2. Software: automation & visualization
AAA’s software provided speed, insight, and transparency:
- Rapid visualization of outstanding and disputed amounts
- Clear distinction between genuine disputes and administrative feedback
- Real-time dashboards for finance and management
- Support for structured follow-up
- Fewer manual errors and less dependency on specific individuals
The combination worked: people ensured follow-up, while software provided oversight and acceleration.
Measurable financial impact

Stronger treasury and financial health
Thanks to the released liquidity, Claeys & Engels’ treasury received a clear boost.
The financial position became so strong that external bank credit lines could be terminated, leading to additional financial gains by avoiding interest costs.
At the same time, AAA’s software ensured that Claeys & Engels is now fully Peppol-proof and can work efficiently with self-billing within the lawyers’ organization.
“For us, AAA is not just a supplier, but a true business partner that brings structure, transparency, and lasting impact.”
