You can use QuickBooks compatible envelopes. Below is one I found online. You can also search online for the better deals yourself.

You can also customize the shipping label on the check if needed from the check layout screen

3. Another option: You can print a check, test and purchase the envelope in Office Depot.


Thank you.

Looking for window envelopes for business checks printed with ezPaycheck software. The standard ones I've seen so far reveal private info on the check (in the memo section). Hope you can help me find a window envelope to display vendor addresses (to whom check is made out).
