Hi wasayali-hotmail,
Welcome to Community! QuickBooks Online provides a vast number of reports, that can be customized to best suit your business needs. Although there currently isn't a way to include currencies on the Accounts Payable Summary Report, I'd be happy to provide you with an alternative option!
To review the supplier amounts, open balances and currency, I suggest the Accounts Payable Aging Detail report. This can be finely tuned with the customization options you're looking for. Here's how;
1. Open Reports from the left menu
2. Enter Accounts Payable Aging Detail, in the search field
3. Hit Customize
4. Select the Report Period
5. Click on Rows/Columns to expand the view
6. Checkmark all areas that you would like to see on the report
7. Open the Filter
8. Add additional options as you see necessary
9. Hit Run Report
If you would like to see additional customization options on the Accounts Payable Summary Report, please don't hesitate to submit a suggestion to our Development Team. Your feedback is always welcome, as we continue to improve and expand our content in QuickBooks Online.
Feel free to reach back out with other questions. We would be glad to help!
