Case Study: Direct Energy Solar achieves real-time inventory control and a 5-month go-live with Rootstock

Direct Energy Solar - Customer Case Study

Direct Energy Solar (formerly Astrum Solar) is a fast‑growing full‑service solar provider that joined the Direct Energy family in 2014. Faced with complex manufacturing, field service and inventory challenges—and monthly inventory adjustments near 5%—the company decided to run its entire business on the Salesforce platform but needed a robust, native ERP that understood manufacturing intricacies.

They selected Rootstock Software, a 100% native Salesforce ERP, and moved from pilot to go‑live in five months. Rootstock now manages purchasing, work orders, field service, BOMs and real‑time inventory; monthly inventory adjustments dropped to under $10,000 and the platform has supported more than 2,000% growth while delivering faster, more reliable implementations.
