vendor who is also a customer
I have a vendor from which I purchase equipment and I also sell their equipment and receive commissions (customer account). In lieu of a commission check how do I use a credit to pay for the equipment.

When a customer is also a vendor, use a barter bank account to pay the vendor. You can find information about barter accounts in your QB help. You can look in the frequently asked questions section of the community forum, too.
