Gordon Hertzman has worked with CompuBooks since 2010 to help address specialized QuickBooks challenges through the integration of customized solutions.

As great as it is, QuickBooks “out of the box” does not always meet clients’ unique business requirements, and Gordon’s custom-tailored solutions affords QuickBooks the missing “fit.” With Gordon’s help, in some cases, customers avoided having to use an expensive “non-QuickBooks” system to meet their needs. In other cases, Gordon’s solutions gave clients enhanced reporting and the magical gift of time: their data loaded in minutes rather than days.

With a strong business background founded in an MBA and many years spent “client-side,” Gordon speaks good “business.” This will make it easier to keep your systems initiative on track and aligned with your business goals.

When you talk, he listens. When you “order a cheeseburger, he won’t bring you a hot dog.”
