ABS started as a simple accounting and software consulting firm.  Today, we have made a name for ourselves as an industry leader in accounting software solutions serving over 1,800 companies and organizations worldwide.  We have grown to keep up with the changing technological environment, all while continuing to offer exceptional service, support, and products. We are a team of programmers, accounting professionals, and support personnel with a goal to help make accounting financials work for you – and to make it easier and faster in the process. 

Every product we choose to support or develop is conceived to overcome practical, real world hurdles our clients encounter in their daily operations. 

The digital age has changed the way business and accounting are done - we’re a far cry from the pencils and notebooks we started with.  But our mission has remained the same: Provide exceptional service and support while helping non-profits and small businesses find the right solution.
