What PM Attendant does

PM Attendant is a sub-brand of ISI Software, a privately-held US company founded in 2001 and headquartered in Edmond, Oklahoma, that sells vertically-specialized oil change management software to automotive service operators. The product suite is built around LubeSoft Express (the comprehensive core platform for multi-location operators) and PM Attendant (a daily-operations companion focused on customer relationships), supplemented by Bay Timer (real-time bay and wait-time tracking via ultrasonic sensors and TV displays), Merchant Processing (integrated ISI Pay payment processing), Marketing (customer engagement campaigns), and Hardware (operator-tailored equipment).

The underlying technology combines a workflow-management software layer with proprietary ultrasonic sensor hardware for vehicle detection in service bays and an integrated payments stack powered by Fullsteam Operations LLC in the US and FS Payments Canada Ltd in Canada. The platform centralizes customer profiles, service histories, inventory, scheduling, and live dashboards, with mobile-accessible reporting and customizable invoicing. ISI is designated a CARFAX Premium Partner (2026), positioning the platform within the broader automotive service data ecosystem.

ISI Software generates revenue through three streams: recurring software subscriptions for its modules (quote-based, not publicly priced), transaction fees on integrated payment processing, and hardware sales to oil change operators. Go-to-market is sales-led and demo-driven via direct channels, targeting everything from single-site operators to multi-location franchisees (with Oilex Operating LLC, a multi-unit Grease Monkey franchisee, as a named enterprise reference). The company serves the US and Canada, maintains a 1-10 employee headcount, and emphasizes direct, in-house customer support with no outsourced call centers.
