Thanks for posting your concern in the Community space. I can help you create a payment for the vendor.
There are some options you can choose to set up a payment for your vendor. You can enter and pay bills for the amount which you wish to be paid later, or create a Check if you want to immediately pay for it.
Here's how to enter bills:
Go to the Plus icon.
Under Vendors, select Bill.
Fill in all necessary information. Choose a term that will indicate and specify when the vendor expects payment.
