BudgetSheet is free to use and try for up to 15 days with one bank account connection. There are no feature restrictions.
If you need to link more than one bank or credit account or need more time, you need to upgrade to BudgetSheet Pro.
Extensions > BudgetSheet > Upgrade to Pro...
Pricing for BudgetSheet Pro is $8/month or $79/year (18% savings).
If you already have a license key, you can enter it into the current sheet to unlock that spreadsheet for BudgetSheet Pro use also.
Extensions > BudgetSheet > Upgrade to Pro... on a spreadsheet that you have already upgraded to Pro
BudgetSheet Pro account limits and restrictions are per license key, not per spreadsheet. A single purchase can be used across multiple spreadsheets as long as you are still within the limits.
Upgrading can be done via the BudgetSheet menu in your budget spreadsheet:
This will display the user account page, which will have a button to upgrade to BudgetSheet Pro.
Clicking on the Upgrade to Pro button will open the payment sidebar:
After upgrading, you may want to link more bank and credit accounts now via the menu:
Extensions > BudgetSheet > Link New Bank Account....
Google Sheets + Bank Transactions. Full control to budget your own way with your own data in your own spreadsheet.
