Frequently asked questions

When does a spreadsheet stop being the right tool?+

Three signals: (1) multiple people writing concurrently with frequent conflicts; (2) business-stopping risk if the file is corrupted or deleted; (3) audit trail required for compliance. Any one of these usually pushes you out of spreadsheet territory.

Is low-code (Airtable, Retool, Bubble) always cheaper than custom?+

Upfront, yes. Over 3 years, often not. Low-code costs $20–80/user/month and the platform lock-in is real. If you have 20+ users for 3+ years, custom software's TCO often wins.

What if a SaaS already covers 80% of my workflow?+

Buy the SaaS, automate the 20% gap. Don't build what you can buy in the standard case. The exception is when that 20% is the part that differentiates your business — then custom is worth it.

Can I run the decision tree for multiple workflows separately?+

Yes — and you should. Different workflows in the same business often land on different verdicts. Run one workflow at a time.
