Accountant asked us to journal off some old inv. and payments that are sitting on the expenses account. I have done it, how do I match the journal against the bill or chq

Hello there, @Kellydd.

I'd be happy to help you match old transactions in QuickBooks Online. If the old expense transactions have been posted to the Accounts Payable or Accounts Receivable, you can create a Pay bill or Receive payment transaction. However, if it's not, then you don't need to create another transactions aside from the Journal Entry. I'd suggest reaching back to your accountant to make sure that your books are accurate.

Here's how to match the Journal Entry (J.E) to a Bill:

1. Select the + New button and choose Pay Bills.
2. Check the box beside the Vendor's name. The credit amount will automatically appear under the Open Balance column.
3. Verify the details and select Save and close.

I've also added these steps on how to add customer's credit to Invoices in case you want to match your J.E with it.

1. Click the + New button and select Receive payments.
2. Enter the details, and check the boxes beside the Outstanding transactions and Credits sections that you want to include.
3. Once done, select Save and close.

This is how it looks like:
