Postage $aver is perfect for small businesses, nonprofits, churches, community newspapers, political candidates or most anyone who needs to prepare bulk mailings. And it's great for print shops and shipping centers who serve those mailers. Use it for cards, envelopes, tri-folds, booklets ... you name it!

To get bulk postage rates, you have to sort your mail into specific trays or sacks according to complicated USPS rules. You also have to prepare detailed postal paperwork. And, even a simple bulk mailing can have eight or more different postage rates to calculate and apply correctly.


Prints an easy-to-follow instruction sheet for each mailing, telling you which zip codes go in which tray or sack in plain language, not postal-speak;

Prints your addresses on popular label formats or directly on your mail piece, sorted in order by tray or by bundle and sack, with barcodes, optional endorsement lines and "Or Current Resident" lines, as applicable.

Automatically computes the lowest applicable postage rates, including USPS nonprofit rates, and fills out and prints the required postage statement and mailing reports;

Automatically prints the required barcoded tray or sack tags on standard business card sheet stock.

Sorts your mailing list file in tray/sack order and adds barcodes and endorsement lines, if you'd rather print your addresses with a mail merge or variable data press.

Postage $aver Pro and Lite are user-friendly. Both versions work with all standard spreadsheet and database formats, including Excel, csv, Access, dBase, Filemaker Pro, and most others, so you save time and money and don't have to re-enter your list.
