FAQ

Questions we hear

Straight answers to what people ask before they hire us.

Do we need Google Workspace?
It helps, since AppSheet works best with Google Sheets and Drive. We can also connect other data.
When should we move off AppSheet?
When you need complex logic or many outside users. We will tell you when that time comes.
Can you fix an AppSheet app we built?
Yes. We review it, fix the issues and tidy the data.
How does pricing work?
Every project is different, so we price it to your spec. Book a free call, and we send a custom proposal with a clear price.
Do you work in our time zone?
For US clients we commit to 4 hours of overlap with US business hours. We agree the meeting times at the start.
Do we own the code and data?
Yes. Your code, accounts, keys and data stay under your control. Nothing is shared across clients.
