As you know, you can import expenses into Bonsai automatically by connecting your bank account. We used to pull expenses for the past 3 months from your bank, by default.
You can also specify the time period for which you want your expenses to be synced to Bonsai from your bank account, with our new improvement :)
Go to Accounting -> Expenses -> click 'Import Expenses' to land on the bank connection page.
Then once you connect your bank account, we ask you to select the time frame of the expenses you want to import, as shown below. The options are 3, 6, or 12 months.
Are you unable to connect your bank account? Please check this article to know about the possible reasons.
