Common questions

Demo FAQ

It's the real app. Same code, same routes, same database engine. The only difference is your workspace is flagged as a demo so you can reset it whenever.
No. The demo uses sandbox credentials, so nothing real moves. Use Visa 4242 4242 4242 4242 with any future expiry to simulate a successful charge.
Yes. The demo workspace accepts CSV, OFX, and QBO imports just like a real workspace. Or skip the demo data entirely and start fresh.
Indefinite. Your demo workspace doesn't auto-expire. If you want to convert it into a paid workspace later, all your work carries over.
Yes. Invite up to 3 teammates into the demo workspace from Settings → Team. Roles work the same as production.
Because if our app is good, you'll convert. If it's not, charging you a dollar to find out is a tax on honesty. We'd rather you actually try it.
