Good day, @sandra.bowers.
For now, the option to add a supplier's bank details is unavailable in QuickBooks Online. I can see how ideal to have this kind of feature in the Online product.
As a workaround, you can add their banking info in the Notes section on their profile. Here's how:
- Go to the Expenditures menu and select Suppliers.
- Click the name of the supplier, then select Edit.
- Go to the Notes and attachments section and add their bank details in the Notes field.
- Select Save.
Another option is to find an app that helps us in handling information. We can look for a third-party app by going to this link: https://apps.intuit.com/app/apps/home
Please let me know if you have other questions. I'll be around to assist you. Hope you're well and safe!
