Assign an Expense account to a vendor

Hello. I am trying to find where or how I can assign payments to a vendor to a specific expense, such as Advertising, Telephone Expense, etc. All payments seem to go to General Expense. Anyone know how to do this.

Hello Paul.
You can assign payments to vendor creating a bill and they register it's payment.

But i think you're mentionning the category from reports. At the bottom on an invoice, you have an option "Recurring and more.."

From there, you can change and create categories for your bills and invoices.

Hope this helps you.

Thanks,
