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.

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.

Discovery and status tools are free; paid MCP calls require explicit buyer wallet authorization. The separate standalone Base-only HTTP APIs include USDC Verify (0.02), Match (0.03), Evidence PDF (0.05), and four DeepSeek-only web operations: Fetch (0.01), Search (0.02), Extract (0.02), Extract + Analyze (0.03 USDC).
