#9 Double Window Check Envelopes, Made in USA, 500 Pack | Ready-Seal Security Tinted Envelopes for QuickBooks, Sage 100, Blackbaud Checks, Self-Sealing Laser-Compatible, Quicken

We use a proprietary software system for churches (widely used in the US). We were told (of course) that only their envelopes would fit their checks. After buying one box for about $120 after shipping I determined never to do that again. I spent quite a bit of time measuring and comparing different alternatives, and decided to take a shot with these - I figured with "guaranteed to fit" I couldn't lose. I had previously had great luck with different #10 double-window envelopes from Amazon. These are excellent! Well made and they appear to be sturdy enough. The adhesive works very well, I have not had to reinforce it. I was most concerned about the window placement - would they fit properly without a lot of fiddling and re-positioning the print fields? They fit our checks perfectly with no drama. The window placement is about perfect. In fact, better than the "proprietary" models, these don't reveal anything on the memo line, but the addresses are perfectly visible. As others have noted, they are just large enough to also accommodate return correspondence such as a tri-fold letter-size invoice copy. Not so large that the check floats around, obscuring the address. I am very happy with these and I am spreading the word to others!

These envelopes worked perfectly! The perfect fit for my checks

Great value for the price when compared to what the accounting software company wanted me to use which was more than triple the price. The adhesive releases easily if you forgot to add something to the envelope. My hope is that the adhesive turns more "tough" once the envelopes go to the post office. If anyone knows the answer, please let me know.

Envelopes are wide enough to enclose QuickBooks checks without having to fold them down AND they’re self sealing!

I’ve had trouble finding envelopes that fit our quickbooks checks. Too expensive from intuit. These are perfect!

Perfect for paychecks!

I've been through more check envelopes than I care to think about - these are the best for the price so far that work with Sage 100 checks. Flip and seal is convenient but I've noted the durability of the seal for any I've tried has been questionable and comes off fairly easily, including these. Size of the envelopes is great - I can include a check with stub and 2 standard pieces of paper max. No issues with address and return address being covered. Also, good security as our checking info is concealed. Overall, would definitely recommend.

I returned these envelopes. The "sticky" flap was not sticky enough to securely seal the envelope.

We have purchased other envelopes from different suppliers but the windows never seem to line up properly with the address information on our cheques or they show too much information, like the cheque amount. The windows in these envelopes line up perfectly with the addresses and aren't too large that they show extra information.

These were a competitive price for staples. Will buy again!

les fenêtres arrivent parfaitement avec l'alignement des écritures de mes chèques SAGE50

Not sure if it is the envelope or the quickbooks program.. I run to move everything to line up with the windows

Quickbooks cheques do not properly fit in these envelopes. The bottom window is 1 line too low and it shows the address plus notes that are written on the cheque below the address. Very disappointed. Would not buy again.
