TESTIMONIALS

What others are saying

"They've been there for us"

"We've used AccountMate for years for our General Ledger and Accounts Payables system. We were also using a propriety printing order system and they were somehow able to integrate the Accounting order data into the printing system, which saved us so much duplicate work."

- Vince M., Co-Owner, TEAM Concept Printing, Carol Stream IL

"Know their stuff"

"They really come through for us when we need them. We needed a lot of custom reports so we can track the profitability of different inventory items and they were able to get them done, usually same day."

- Danny F., Owner, Fox Outdoor Products, Melrose Park, IL

"Never looked back"

"We had problems with another vendor so even though they were physically closer, we left then for Chicago Business and have never really looked back. They're really dependable when we need a customization or special report done.

- Denise W., Doric Products, Marshall, IL
