Accounting Software Window Envelopes

These envelopes measure 3-9/16 by 8-3/4 inches and feature a double poly window layout designed for accounting software output. The white sulphite stock is SFI certified with 92% brightness and a vellum finish. A blue Wesco inside tint adds document security. Two side seams sit under the windows and a remoistening seal closes the flap.

Suits high-volume statement mailing

Offices that print cheques or invoices from accounting packages will match the fixed window positions. The 500-count box supports regular batch runs. Buyers who need a different window size or a single-window format should look at other envelope styles. Custom branding or non-standard paper weights are not covered by this product.

Simple load-and-print workflow

The envelopes feed from the box into standard laser or inkjet trays without adjustment. Moistening the flap activates the seal for hand or machine closing. Misaligned printer settings can shift content outside the window openings. Static buildup on the poly film may cause occasional double feeds in high-speed printers.

Questions about this item

What printer do I need to print on these 500 envelopes?

Any desktop laser or inkjet printer that accepts 3-9/16 by 8-3/4 inch media and feeds envelopes from a manual or dedicated tray will work.

Will the double poly windows jam in my older laser printer?

The poly film tolerates standard laser fuser heat, but test a few sheets first because some legacy models with tight paper paths can catch the window edges.

How can I confirm the windows line up with my accounting software output?

Print a test page on plain paper, hold it behind one envelope, and verify the top window shows data at 7/8 by 3-1/2 inches and the bottom window at 15/16 by 3-1/2 inches.
