Who it is for
Credit control and finance teams that chase late invoices and want the account history and the next reminder in one place.
Accounts receivable and collections follow-up from chat
Overview
Billabex brings an accounts receivable workflow into ChatGPT. Finance staff can pull up invoices, credit notes and their allocations, customer accounts and contacts, outstanding and overdue balances, and the email traffic tied to each account.
Actions go beyond reading. The app finds unpaid invoices and customers who have gone quiet, opens full communication histories, updates billing and contact records, pauses or restarts automated reminder sequences, drafts scheduled messages, and sends personalised payment reminders. Tasks raised by the Billabex agent can be answered in the same conversation.
Bundled skills cover aged receivables analysis, daily briefings, risk identification, and follow-up email preparation. The developer's example prompts are written in French.
Credit control and finance teams that chase late invoices and want the account history and the next reminder in one place.
Both halves of collections are here: reading the receivables ledger and actually sending or rescheduling the reminder emails.
Availability
Billabex is listed in the ChatGPT apps directory only. Billabex has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Billabex, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
