About Us


CheckBuilderPro™, BatchBuilder™ and The CheckPrintshop™ are products of Knappster Solutions LLC™, a limited liability company, started in 2004 by Marty Knapp. We are located in Blaine Washington - about 90 miles north of Seattle. Our main focus is check printing software and supplies through our two web sites: Here at www.CheckBuilderPro.com and our sister site: www.TheCheckPrintshop.com.

For years we used a popular Windows-based check printing software program to print our checks. But being primarily Mac users, we kept hoping that someone would come out with a Macintosh version. After years of looking and waiting, we finally put together our own for in-house use. It was pretty basic but it did the job.

Wondering if there were enough other Mac users out there who would be interested in check printing software, we took the plunge and spent some time polishing it and adding lots of user-friendly features. We released "CheckBuilderPro" in the Fall of 2010 and have been making improvements to it ever since.

Originally, CheckBuilderPro just printed blank checks to use in other programs like Quickbooks. Now it's also able to print completed checks with payee and amount, has a check register, can print reports and allows you to reconcile your bank statement. With the addition of the BatchBuilder add-on module, it can also take a data feed from a spreadsheet file and automatically print checks for each payee.

The CheckPrintshop came about as the result of requests from digital print shops. They wanted additional features to allow them more latitude in designing and printing checks for their customers. Rather than tack these on to CheckBuilderPro, we started with a blank slate and created the software for this specific market.

We work very hard at customer support and find great satisfaction in happy customers. Here's a typical response to our tech support:

“I can’t thank you enough for your response. I have never had anyone respond so quickly and generously” —George Paige

Marty's first computer was a Mac SE/30 and right away he took an interest in writing software. The first program he wrote was a computerized rolodex. He's made the dubious claim that it actually worked . . .

In his "spare time" Marty builds custom electric guitars and enjoys camping in his vintage Airstream trailer.
