BigChange

BigChange provides field service management software for plumbing, HVAC, electrical, and facilities maintenance companies with strong van-stock inventory capabilities. Each engineer's vehicle becomes a tracked stock location, with parts allocated per job, returns processed automatically, and replenishment triggered as inventory depletes. Mobile apps let technicians scan barcodes, request parts, and document inventory consumed on each work order. Integration with accounting systems closes the loop on parts billing and cost-of-goods reporting.
