Save Time Sending Invoices with our Quickbooks Invoice Envelopes
Quickly and easily send hundreds of business invoices or statements with our wide envelope design and our easy to use peel and seal flap.
- Our Peel and Seal flap with low profile window design creates a wide opening so you can quickly stuff several invoices into the envelope. These 2 window envelopes prevent invoices from getting stuck during stuffing
- Once sealed, no adhesive is exposed so you do not have to worry about the envelope sticking to other mail
Business mail will be completely secure during transit
It can be so difficult to find envelopes that create a strong lasting seal thus forcing you to waste time using glue sticks or tape to close the envelopes. Our invoice envelopes are designed to immediately create a strong seal so you do not have to worry about your contents being exposed to others.
Unlike flip and seal envelopes that are messy and even after sealing can still stick to other mail, our peel and seal design quickly seals with no mess and the envelope will not stick to your other business mail
Security with a Professional Look
It can be frustrating to purchase envelopes only to find them flimsy enough to have you worried about their durability during transit. Our envelopes are made of 24 LB White wove paper that will provide a professional look from the box all the way to your destination
