I want to make sure that I can address your concerns correctly, userdrblyne.

We can still update the details of your creditors/suppliers in QuickBooks Online. Here's how to do it:

1. Click Expenses on the left menu and go to the Suppliers/Vendors tab.
2. Click on the creditor's profile and select Edit.
3. Update the Display name as and other necessary details.
4. Click Save.

Note that your creditors will use the Accounts Payable when creating bills. Here's a link that might help you in the future: What is the difference between bills, cheques, and expenses?

If I didn't get your concern correctly, please provide us additional information. This would help us know where we can start and how to correct the details. Thank you in advance and have a great day!
