24 reviews

  • Perfectly fits QuickBooks checks or other computer printed checks without displaying check amounts or memos in the address windows
  • Our unique double window design has been formatted specifically to suit QuickBooks checks without your having to adjust the settings in your software
  • Peel and seal flap makes it simple to close without having to lick or moisten the glue
  • Low profile flap and slightly wider-than-standard design creates a wide opening for easy and quick envelope stuffing of tri-fold, voucher, and 3-per-page check paper
  • Dark security tint lining keeps your important documents securely concealed throughout transit


It can be so difficult to find envelopes that fit QuickBooks checks perfectly. Some will show the recipient's address, but not the sender's address; while others will hide parts of the addresses. Worst of all, many standard envelopes will reveal parts of the check that should always remain concealed, such as check amount or memo line. So much for security! However, our no. 8 windowed check envelopes have been designed specifically to work with QuickBooks checks out of the box.

Our unique bottom window design is formatted so that your check amounts and memos will always be hidden, and both window locations are positioned perfectly to line up with the return and recipient addresses – with no need to adjust the formatting from your software. Just print your checks, insert, peel and seal, and mail!

Perfect for QB checks!

I had trouble finding envelopes that would work with QuickBooks checks. These work perfectly covering up the important info on the checks, and the price was the best I could find. And, fast, free delivery was great!

Double window security check envelopes

The envelopes are just what I needed, but I ordered two boxes of 500 envelopes and only received one box so far. (?)

Perfectly placed windows

I do not use QuickBooks, but Sage. I have been looking for an envelope that fit my checks exactly when I folded them. I had to move 4 lines to left, 1.5 spaces, and they fit perfectly! That's what I wanted, and now when I'm stuffing envelopes, I smile every time I flip it around and see the addresses perfectly placed in the windows. I'm VERY happy with these envelopes.
