I was having QuickBooks issues and mistakenly called QuickBooks for help. I wish I would have called JCS first!!!! David was extremely helpful and I highly recommend JCS!! I will NEVER call QuickBooks support again, JCS will be my first and only call :)

Hands Down 5+ stars. Our company suffered poor support and lack of training for several years... We consulted multiple specialists before being referred to JCS. No contest - JCS took the time to actually understand our struggles and made recommendations based on our business needs. A few meetings later, JCS recommended moving from Sage 50 to Intuit QuickBooks Enterprise. This was without a doubt a very large project - not only were we doing a data conversion, we also had several areas in our Sage 50 that werent being utilized properly and couldnt be transferred in addition to poorly trained staff from prior years of bad habits. With strict time restraints, JCS worked diligently over the Christmas Holiday while our offices were closed to ensure our business could operate upon our return in the new year. Their approach and diligent timeline was completely mapped out. We didnt fear for a moment that we forgot something or didnt remember a step - they had all bases covered.2 months later we are ecstatic to say JCS was able to not only perform this challenging project but also train our staff effectively through the process. Waste no more precious time to find the best consultants - JCS is your solution.

I have worked with JCS since 1995. They are knowledgeable in their understanding of accounting software and very professional. They have provided our staff with training and keep us posted on any updates or developments.

JCS Consultants completely understand Sage 100 and have helped me multiple times with issues and questions I have had.
