Open Mobile provides mobile telecommunications services throughout Puerto Rico, with 18 stores, several towers, hundreds of employees, a thousand vendors and tens of thousands of customers. It has direct relationships with cell phone suppliers such as Samsung and Apple.

Open Mobile had used a United Kingdom-based system originally installed by its predecessor, Cedar Financials, but switched to Acumatica Cloud ERP because it delivered requisition management with approvals and budget control as well as all required ERP workflows for a fraction of what they would have paid for the other products.

ERP Solution

When considering their options for upgrading Open Mobile looked at Oracle eBusiness Suite and Microsoft Dynamics, as well as Acumatica. Their local partner, Bob Bolte, Owner of New Day Technology (NDT) reports that Open Mobile chose Acumatica because it delivered requisition management with approvals and budget control as well as all required ERP workflows for a fraction of what they would have paid for the other products. Diaz had concerns about control, but an Acumatica technical manager convinced him: “He said we would be in control. We would be given the option to upgrade, and could choose to upgrade or not. That was a key factor in the decision.

Another factor was that we can do the hosting; if we don’t like it, we can change.” The CFO, Federico Grosso, says, “Acumatica was a fully integrated, cost-effective ERP solution. Our business objective was to increase efficiency in key processes: improve the requisition workflow; purchasing and Accounts Payable efficiency; automate the expense report process, and improve financial reporting.”

Benefits for Open Mobile

Acumatica will help Open Mobile in several ways, according to Grosso: “It will place us in a position to improve accounting processes and efficiencies… and financial reporting and analysis. We can spend less time extracting data and more on analysis. It will increase the integrity of our data. Before, we had to have an analyst working no less than two or three hours full-time on the report. Now, you can click a button and get it yourself.”

Grosso adds, “The fact that you can access the workflow from any place on any device is great. I recently understood the full benefit of this capability when I was away from the office, in the middle of a congressional hearing. Someone sent an email saying, ‘I need an approval, it’s urgent.’ I pulled out my phone, logged on to Acumatica and was able to approve the request. I said, ‘This is amazing.’

This is twenty-first century technology and it really will make a difference.” For the CFO, having a reliable ERP system is critical: “It’s crucial to have data integrity, and crucial that we have in-house knowledge and support. Acumatica was one of the best projects we did at Open Mobile; on-time, on-budget. We’re very happy here.”
