Hi there, @efish123.

I'm here to assist you with your query about paying a vendor using Bill Pay.

When you pay a vendor using QuickBooks Bill Pay, the vendor does receive information regarding what that payment applies to, specifically their invoice number. When making a payment, you are prompted to enter the necessary information that would show to your vendor after paying.

By entering the bill number, you are providing the vendor with the necessary information regarding what the payment is for. This helps both you and the vendor keep track of which invoices have been paid and ensures accurate record-keeping.

Moreover, you can also learn how your vendors are notified when you schedule a bill payment.
