The problem

Freelancers and small businesses face on average 30 to 60 days of payment delay on their invoices, and most have neither the time nor the tools to follow up effectively. Existing solutions are either too expensive (classic recovery agencies, 15–25% commission) or too rudimentary (Word template + copy-paste). Nobody offers clean escalation on unpaid invoices with automatic follow-up then Electronic Registered Letter with legal value.


The solution

Ethical debt-recovery SaaS, designed for French freelancers and SMBs. Multi-sheet Excel invoice import, automatic client deduplication, 3-level escalation pipeline: friendly reminder, formal follow-up, formal notice. AI-assisted generation of follow-up emails calibrated by tone (humble vs corporate per segment). Electronic Registered Letter sending via MySendingBox integration (legal value). Tracking dashboard, real-time statuses, accounting export.
