Customer Success Story: Andy Gump

Andy Gump is a family-owned and operated business that has provided temporary site services such as sanitation, power, and fencing to Southern California for over sixty years. In this service-based industry, keeping customers happy is a critical goal, and delivering the highest quality of service at this level of scale requires true excellence in logistics supported by mission-critical software applications. To solve this challenge, the company required an ERP solution that could be customized to work seamlessly within their business processes.

“There really is no great software built specifically for our industry, so we have to heavily modify most of the solutions we work with,” said Tariq Batarseh, Andy Gump’s ERP Administrator.

The company had been developing custom business processes on their old ERP system for over eight years, constantly modifying as business requirements changed. To identify an ERP solution that required less effort from internal resources, Andy Gump turned to Western Computer based on the strong technical expertise and ERP knowledge demonstrated by the Western Computer team.

Batarseh and his team worked with Western Computer to implement Microsoft Dynamics NAV as the core ERP solution. NAV provided the capabilities Andy Gump needed to manage complex business processes along with the flexibility to customize the software to meet the company’s unique needs. With NAV in place and by leveraging the consulting services offered by Western Computer, Andy Gump was able to easily modify existing workflows within NAV and quickly build a proprietary servicing module.

“This is the beauty of the NAV platform,” said Batarseh. “You can make it do whatever you want it to do.”

The NAV ERP platform makes driver dispatch and routing more efficient and enables the company to deliver high-quality service at a lower cost. The solution also allows users to access information and customize views. In addition, Andy Gump benefits from mobile capabilities that streamline data flows into the ERP system and permits end users to run reports on the data from any device

“There is a strong team at Western Computer that supports us,” says Batarseh. “It’s a true blessing. From top to bottom, Western Computer demonstrates that they care about their customers.”


Andy Gump Temporary Site Services is a Southern California success story with a five-decade history. Now welcoming the third generation into the business, our family-owned company still reflects the core values of our founder, Massena “Andy” Gump.

Since the 1950’s, Californians have become accustomed to seeing their portable restrooms at various construction and event sites across the region with the sign, “Another Andy Gump” on the front door. They have become not only the most recognized names in their industry, but they have also been innovators from the very beginning with many of their best ideas coming directly from customer suggestions. Andy has always said, “we’re here to help people, not just to sell a service.” With that motivation in mind, Andy Gump is well-poised to continue to maintain both their strong reputation and their business growth.
