About Cumula 3 Group


Our Values

Cumula 3 Group was formed in early 2014 by a team of industry veterans with a desire and passion to provide NetSuite solutions with the customer first and foremost in mind. 
This passion fueled with a little caffeine has enabled Cumula 3 Group to become one of the leading 5-Star NetSuite Solution Providers providing end-to-end NetSuite software and services.  

We Are All About You

We know that without you there is no Cumula 3 Group. In fact, we're big fans of "The Golden Rule".  It's what drives all of our decisions here at Cumula 3 Group.  We treat all of our employees, partners and customers like we would want to be treated. 

We Lead By Example

When Cumula 3 Group formed just a few short years ago we knew we had assembled an amazing team and had a great vision for how NetSuite consulting should be done but had no idea to the heights we would grow in just four short years.  The industry recognized Cumula 3 Group as a 5-Star NetSuite Solution Provider, the high distinction in the industry.


We Are Focused

NetSuite is all we do! This laser focus enables us to bring a level of depth and expertise that is difficult to match in an industry crowded with consulting firms that represent a multitude of platforms and products. 


We Are Local

Cumula 3 Group's growth has enabled us to attract and hire talent from all across the US. We have strategically hired to provide our customers a regional presence in SoCal, NorCal, Mid-West, Southeast and Northeast.


Leadership Team

The management team and staff at Cumula 3 Group includes MBA's, CPA's, software developers, management consultants and more. We have the skills and passion to deliver high quality professional services to help you improve and automate your business processes.
