How to use it

  1. Open the MakeInvoice GPT.
  2. Describe the document type, buyer, items, quantities, prices, currency, dates, and notes.
  3. Open the MakeInvoice.ai draft link returned by GPT.
  4. Review, edit, sign or stamp, then export the PDF from MakeInvoice.ai.

Example prompt

Create a proforma invoice draft for Harbor Foods, one design service, quantity 1, rate 450 USD.

For multi-line documents, include each item description, quantity, and unit price so the GPT can create a cleaner draft.

Custom connector setup

If you are configuring your own GPT Action or connector, use this MCP endpoint:

https://makeinvoice.ai/mcp

The GPT app already uses the MakeInvoice draft-link workflow. Use the endpoint directly only when you are building a custom setup.

Boundaries

  • Do not treat the draft as legally, tax, customs, or payment verified.
  • Do not include passwords, card numbers, or private banking credentials.
  • Always review the draft in MakeInvoice.ai before sending the exported PDF.
