Hi @catie-winrod,
Welcome to the Community!
Let me walk you through on how to add attachments in QuickBooks Online. Here's how:
- From the left menu, select Expenses, then Vendors.
- Choose the desired vendor, then Vendor Details.
- At the bottom left of the page, select Attachments.
- Browse and select the file you want to attach, then select Open.
Once you've attached the file, you'll need to manually update the vendor profile information.
Let me know if you have other concerns. I'd be glad to help.
