Create, send and track invoices from a conversation in Claude, ChatGPT or any MCP client that supports OAuth. Draft an invoice from one sentence or from last month's invoice for the same client, finalize it, email it to your client and send payment reminders for overdue ones. See revenue by month and by client, download PDFs and e-invoices (ZUGFeRD, XRechnung), and export DATEV packages for your tax advisor. Invoices follow the tax rules of 25 countries, including reverse charge and the small-business VAT exemption. New invoices are drafts, and nothing is emailed until you ask. Pay per invoice with no subscription: the first invoice is free.
