Can banking data be imported if company setup was effective 18/7 but info exists prior from Feb?

You can import bank data past your start date, siddiqa.chiboo.

You'll want to check with your bank first if they can provide a copy of the bank transactions. If they do, you can import the transactions using .CSV file.

There's a format you need to follow to import the data successfully. You can check this article to know more about the formatting: https://community.intuit.com/articles/1773099.

1. Click Banking on the left pane.

3. Select File upload.
4. Select Browse and choose the file.
5. Click Next.
6. Follow onscreen instruction.
