Thanks for dropping by, Abdishirdoonwars. I can guide you on how to add accounts payable (AP) in QuickBooks Online (QBO).

When you make a bill in a different currency, the system creates an AP account with that foreign currency. We can start by creating a dummy bill using your vendor's currency to achieve your goal. Follow the steps:

1. Sign in to your QBO account.
2. Click the +New icon, and then Bill.
3. Select the vendor's name with the foreign currency. If you haven't added yet, learn how to set up a vendor from this article: Add a supplier in QuickBooks Online.
4. Enter the details, then save the transaction.

After this, let's review your AP accounts by going to the Chart of Accounts located in the Settings. You'll be able to find the dummy bill there and delete it if needed:

1. Open the transaction.
2. Select Delete from the More button.
3. Hit Yes to confirm the action.

Furthermore, if you don't plan to use an account anymore, you can make it inactive. You can refer to this article: Make an account inactive on your chart of accounts in QuickBooks Online.

Let me know in the comments if you have additional queries while following the steps on adding an accounts payable. I'll be glad to work with you again.
