Actually, as posted in other threads, you CAN do a check for someone that is NOT a vendor.
I have done it multiple times over the years.
Click +New
Check
Leaving the Payee blank, go to the Mailing Address. Type in Name (and address, if needed) of person receiving the check.
Date
Check No.
Then, under Category Details, put in pertinent information and Save or print, from there.
I also have, listed as a "vendor", General Vendors.
So, instead of an actual name of a vendor, it is actually just General vendors. I can use that as a "General", not an every day vendor, kind of place to post these not often used "vendors". The accountant says that is a good way to do it, to make them a little easier to find, if need be.
When I use that "General Vendor", I change the name in the address field to whomever it is that Im posting or writing the check for.
