FAQ
Do I need a paid AppSheet plan?
You can build and test for free. When your team starts using it, AppSheet needs a Core licence for each user, which Google Workspace Business plans include. I'll tell you upfront what you need.
Who owns the app?
You do. It's built in your own Google account and Workspace, and I hand over full documentation.
Can you fix or speed up an app someone else built?
Yes. I review it, fix slow syncs, broken bots and security filters, and explain what changed.
Can clients or vendors log in and see only their own data?
Yes. I set up security filters and user roles so each person sees only their own records.
Will it work on mobile and offline?
Yes. AppSheet apps run on Android, iPhone and desktop, and can capture data offline and sync later.
Can it send emails, PDFs or reminders automatically?
Yes. Automation bots send emails, generate PDFs such as invoices or reports, and run scheduled reminders.
What if my needs grow later?
The app is built so you can add tables, views and bots without rebuilding it. I also offer monthly support.
Not sure which package fits?
Send me a short description of your process and I'll recommend one before you order.

Working with Harsh was great. We had a rather large, rather complicated project in mind that Harsh took great care in understanding our desired outcome and working with us in adjusting/adding details as we went. We already have other projects lined up that we are excited to see his work on.
