Keep the stack short.

You already have hosting. These are the other pieces. This page is written as recommendations, not a deal dump — add an affiliate URL later if you actually use the tool. Disclose it.

Sell the files

  • Lemon Squeezy

    Merchant of record. Handles VAT. Best default if you do not want to think about tax.

  • Gumroad

    Fastest to first sale. Fine until international VAT becomes annoying.

Find the site

  • Google Search Console

    The only analytics that matter for this model. Look monthly, change one title.

  • Umami or Plausible

    If you want counts without a cookie banner. Optional.

Directories, once

  • Indie Hackers Tools

    People here already buy small software and templates.

  • AlternativeTo, Sidebar, There is an AI for that

    Submit the calculators, not the shop. The shop rides along.

How it all fits together is in the playbook. Desk is where checkout URLs go.
