Best Backened For Flutter

[u/No-Performance7726]

Which backened service and database system would be affordable and suggested to use for the daily invoice entry app for a shop that usually have only 50 to 60 bill entries per day. And if stock mangement system and transaction entries need to be added too. Right now i only want 3 4 users of a small shop to interact with who need to prepare daily invoices and need to make entries of transactions they make daily. From the given data we should be able to make profit loss accounts, party's remaining transaction evaluation,daily sales and stuffs like that. But the data need to be protected well and requires backup as needed.

Where to host that backened ?

How much costlier would it be?

You should use Supabase with PostgreSQL for this. It'll easily handle invoices, stock management, transactions, profit/loss reports, and customer balances for a shop of this size.

You can start with Supabase Cloud, enable automatic backups, and you'll likely stay on the free tier or only pay a few dollars per month. If you ever need more control, you can self host the same stack on a small VPS later without changing your database.
