"The Govt. of Israel - Ministry of Defense Mission in New York (www.goimod.com) has purchased QBProfessor's custom software (OpCenter) to automate a complex procedure in QuickBooks. We were very satisfied with QBProfessor's performance and the fact that they delivered the software long before the purchase order dealine.
Based on our experience, I am happy to recommend QBProfessor as a vendor for adding or changing functionality in complex software such as QuickBooks."
