Definition
Fixed operations, or fixed ops, are the departments of a car dealership that service and repair vehicles rather than sell them: service, parts and, where the store has one, the collision center or body shop. Their revenue includes customer-pay repairs, warranty work paid by the automaker, parts sales and internal work such as reconditioning used cars.

What it means for a dealership
The term sets these departments apart from variable operations, the vehicle sales side, whose results swing with the market. Fixed ops income tends to be steadier because vehicles on the road keep needing maintenance and repairs. Many dealers track service absorption: the share of the store’s overhead that fixed ops gross profit covers.
Service is also where loyalty is won or lost. Every repair order is a chance to keep an owner coming back and, later, to sell them their next vehicle. That makes the service phone line a revenue line. Missed calls, slow appointment availability and long waits can push owners to independent shops.
Common fixes include more advisors or BDC agents on the phones, online scheduling and AI voice assistants that answer after hours and during overflow. Whatever the mix, measure how many service calls get answered and how many turn into booked appointments.
