2. Choose the Chart of Accounts tab.
3. Select the New button. 
4. From the Account Type drop-down, choose Bank.
5. Pick the appropriate category from the Detail Type section.
6. Enter a term that will identify the account in the Name field.
7. Fill in the remaining fields.
8. Click the Save and Close button. 

Once completed, you can now import your bank transactions using a CSV file. Here's how:

2. Select Import Data.
3. Choose Bank Data.
4. Click the Browse button. 
5. Navigate to where you saved the bank file.
6. Follow the on-screen instructions from there to map and import your data.
