How do I write a check to a customer. Quickbooks won't let me set them up as a vendor and I can't produce a check from the customer file?

I'll help you write a check, DebbieZ.

When creating a check for your customer, you don't need to add them as a vendor. Let's go to the + New menu to record the transaction.

Here's how:

1. Go to the + New menu.
2. Select Check.
3. On the Payee field, scroll down to select the customer's name.
4. Add the other necessary details.
5. Once done, click on Save and close.
   
   

I've also added this article that'll help you track and manage your expenses in QuickBooks Online: Vendor Transactions.
