Another Option is to use Vendor Name: Other and put the Vendor name in the memo field. You can also use Misc Restaurant, Misc Electronics, etc and put the name in the memo or address field in Quickbooks.

I add the vendor's name somewhere on the expense just in case I need to locate a receipt or another person has to do the accounting, etc.

I have received a past due bill from a vendor mailed to me up to 1 1/2 years after the office visit. I was able to search Quickbooks for the Dentists Name and use that to verify the bill was already paid.
