About Sheet & Flow
Sheet & Flow makes practical spreadsheets and n8n automations for landlords, freelancers and small teams, plus free tutorials that show how they work.
How products are tested
- Spreadsheets are recalculated in a spreadsheet engine and every result is checked against a separate calculation. A spreadsheet only ships with zero formula errors.
- n8n workflows are imported and run in a real n8n 2.x install against test services. That includes the failure cases: bad tokens, sites going down and coming back, duplicate errors.
- The Self-Hosting Kit was tested by building a real stack, backing it up, deleting all of its data, and restoring it, including onto a fresh server.
Use of AI
We use AI assistance to build products and write content. Everything is tested before it's published, and each tutorial says what was tested. If you find a mistake, open an issue on GitHub and we'll fix it. Questions about a purchase? Reply to your Gumroad receipt email.
Not advice
Tax, accounting and real estate content is general education. It isn't professional advice. Talk to a qualified professional about your situation.
