Harper + human expertise
Whether you work with a consultant, manage the process internally or have not started yet, Harper is the strong card: human expertise and automation without compromise.
You pay a significant fee, but your R&D funding is not always actively steered and the added value can feel unclear.

Keep the expertise, improve the steering
A cumbersome Belspo interface, manual encoding, no timesheet integration and a higher risk if your file is reviewed.

Maximize recovery, secure the file
You may be eligible, but nothing is structured yet: no clear estimate, no process and no file ready.
