Hi there, SooSacks.

To do this, you can either use a Bill or an Expense transaction. A bill is used when you pay the supplier on a later time. Use expense when you pay your supplier right away.

Also, there's a way to enter a new vendor who is already your customer. You can add other characters to their name to make it slightly different.

For example, if the customer's name is Abbie Marge, you can enter the supplier's name as Abbie V Marge. This way, QBO will let you have a vendor and customer with the same person.

I've added a sample screenshots for you:

Customer:

Vendor:
