Do I have to create a Supplier / Payee code for every single Bill/ Expense even though it might occur only once or twice? This would make the supplier list very long.

Hi there, naas-ideon-gmail.

Welcome to the QuickBooks Community. Please know that we aim to deliver customer satisfaction at all times that's why we address an issue as soon as possible. That said, may I ask for further details on what are you referring to Supplier/Payee code for every single Bill/ Expense? are you trying to create an entry number or tax code? I appreciate any extra details so I can suggest an accurate solution.

For now, I'm adding this article to see steps on how you can run a specific report that will reflect all payments made to suppliers: Run a report with supplier totals.

Keep in touch if you need any more assistance with this, or if there's something else I can do for you. I've got your back, aas-ideon-gmail. Have a good day and keep safe!
