What are the measurements from the top and side of the envelope? Thank you!** A: This envelope is designed for "checks" not for 8.5" x 11" sheet, the dimensions is: envelope size 8 11/16 3 5/8 "top window" 3 1/2 by 7/8 2 3/8 from bottom and 3/8 from left, "bottom window" 3 1/2 by 7/8 3/4 from bottom and 7/8 from left **Q: Are there other brands of voucher checks (besides Intuit) that work well with these envelopes?** A: Are you talking about the actual checks or the software you use to print the checks? I get my checks through Nebs or Deluxe, but use QuickBooks software and these envelopes work perfectly. **Q: which envelopes are made for invoices ??** A: These envelopes are made for Quickbooks checks and do not fit the invoices. I use a #10 business envelope with a left side window. 4 1/8 in X 9 ½ in. I haven’t researched if there is a double left side window envelope for invoices. Hope this helps. It seems like supplies from QB are very expensive. I would see if you can research QB to see if there is an envelope and then see if you can get them from Amazon. Much better price. Kathy Roberts **Q: How many checks will fit in one envelope?** A: I only use this for business checks with stub. This fits perfectly in the envelope. ## Customer Reviews ### ⭐⭐⭐⭐⭐ No issues *by E***C on September 17, 2025* Good product.
