14 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
  • Flip and seal flap is quick and easy to use without any need to lick or moisten the glue 
  • 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!

    Key Features:

    • #8 double window envelope
    • Dimensions: 3 5/8 inches X 8 11/16 inches
    • Security lining
    • 24lb white wove paper
    • Package quantity: 500 Count


    • This envelope is equipped with a flip and seal closure, does not require moistening, but cannot be used in a bulk mail machine. For envelopes that can be used in a mail machine, you’ll want to use a gummed seal envelope.
    • This envelope should be stored in a dry, clean environment, as the latex glue on the flap will deteriorate when exposed to dust or moisture. The glue will also break down over time, so for best results, expect the self-sealing glue to bear a standard shelf life of about 12 months from purchase.
    • This envelope is not suitable for printing in a laser printer, as the heat will melt or warp the windows.
    • While this envelope will work with QuickBooks checks, it is NOT designed for sending QuickBooks invoices, as information will not line up properly in the windows. Please click here for envelopes suited for mailing QuickBooks invoices.

      Best envelopes for Quickbooks

      These are my new favorite envelopes for my Quickbook checks. They have a smaller address window that prevents information on the check memo line from showing.
