No AI? No problem. Everything works from the DueChat web app, and the email chase runs on its own.
Even when your AI is closed, the follow-up still goes out.
Every invoice gets a polite 7 / 14 / 30-day email ladder, signed with your name. Your AI can pause, resume or send one early — but it doesn’t have to remember.

DueChat is the accounts-receivable tool your AI uses. It keeps your invoices, clients and payments, and gives Claude, ChatGPT and Cursor safe tools to find who owes you, draft invoices and chase payment. It also sends polite 7/14/30-day email reminders on its own. Money goes to your Stripe or bank.
In the DueChat app, open AI agents and create a scoped API key (dc_mcp_…). Add DueChat as a Streamable HTTP MCP server in Claude or Cursor with that key, or use it in ChatGPT connectors. Custom GPTs can import our OpenAPI schema. Connection is by API key today — there's no one-click sign-in yet. Full steps are on the MCP page.
Sending an invoice, sending a reminder and marking paid all return a preview first — nothing goes to a client until you confirm. Keys are scoped (read / write / send) and revocable, totals are calculated on DueChat's server rather than by the model, and every tool call is written to an audit log you can review.
No. Everything works from the DueChat web app, and the 7/14/30 email chase runs automatically whether or not an AI is connected. The AI is a faster way in, not a requirement.
No. DueChat chases by email only — reminders go out in your name, and client replies go to your own inbox. There are no phone or voice calls.
Free covers 3 invoices a month, resets monthly, with no card to start — AI access included. Pro is €12/month or €120/year after a 30-day trial, with unlimited invoices and AI use. On Free, DueChat takes 1.5% of Stripe-collected payments; Pro has no DueChat fee.
If your client pays through the Stripe link, DueChat detects it and stops reminders automatically. If they pay another way, mark the invoice paid — from the web app or by asking your AI (you'll confirm first) — and reminders stop.
