# Billabex

Billabex is a B2B accounts-receivable SaaS. Invoices arrive through several channels at once
(billing connectors, manual entry, the public API, the MCP server), and an AI agent then runs the
follow-up with the debtor on behalf of the client organization: it reopens the conversation,
works out what is blocking payment, adapts tone and channel per account, and escalates to a human
only when a decision is needed. It operates upstream of litigation.

Billabex opère en amont du contentieux : l'agent relance, comprend ce qui bloque le paiement et
fait avancer le dossier jusqu'au règlement, sans dégrader la relation client.
