FixKit AI

Home / Use case

Take payments (cards or crypto)

“How do I get paid for the thing I built?”

Card processors, merchant-of-record services that handle sales tax for you, and self-hosted crypto.

Fix it yourself in 3 steps

  1. Pick the simplest option that matches what you sell.
  2. Start with a hosted payment link — no checkout code needed.
  3. Test with a small real payment before you announce it.

Copy this prompt

I sell [product] for [price]. Recommend the simplest way to take payments for this, set up a hosted payment link, and give me a checklist to test it with a small real payment. Stop before going live.

Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
