# 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.

Homepages, help articles, blog articles and the four legal pages per published language are also
served as Markdown: drop the trailing slash and append `.md`, or send `Accept: text/markdown`
to the canonical URL. Pages with a Markdown variant announce it through a `rel="alternate"`
link of type `text/markdown`; other marketing pages do not have one.
A path that does not exist answers 404; send `Accept: application/json` to receive it as RFC 9457
Problem Details (`application/problem+json`) with a `code` and a `resolution`.
