ONEFLOW ESTIMATOR: MAJOR BENEFITS
Estimating is one of the biggest challenges shops face in their daily workflow. The time it takes service advisors to build estimates creates a major bottleneck – slowing down operations and delaying revenue. Instead of moving work forward, estimating often gets in the way of getting work done, including:
- Time – Hours lost building estimates, many of which never get approved
- Accuracy – Incorrect parts, labor, and pricing erode profitability
- Potential – Missed opportunities for upsells and related services
OneFlow Estimator eliminates bottlenecks in the shop. It unifies the industry’s most powerful proprietary data into a single, intelligent estimating experience – turning a time-consuming, error-prone task into a faster, more confident step in the workflow.
Automatically matches labor, parts, fluids, and related jobs to eliminate guesswork and missed opportunities. Users can search using natural language ("front brake pads" or "30K service") to get results. This ensures a smooth, end-to-end process – eliminating re-entry, reducing errors and keeping work moving.
Produces estimates based on real repair data, not assumptions, delivering VIN-specific accuracy based on how vehicles are actually repaired in real shops. Built by the company that pioneered shop estimating – powered by the Snap-on Digital Engine and decades of Mitchell 1 expertise – OneFlow Estimating delivers the fastest, most accurate estimating experience in auto shop management.
Delivers clear, accurate, and transparent estimates customers can trust. Consistent, data-driven pricing removes uncertainty and builds confidence at every step – helping service advisors explain recommendations more effectively. This drives faster approvals and stronger customer relationships.
Shop professionals stay connected from inspection to estimate and approvals with OneFlow Estimator + Inspections. The mobile-friendly process enables technicians to capture photos, videos and technician notes on mobile devices that flow directly into the Manager SE Job View suite – triggering faster estimates from service advisers. This helps you build clear, accurate estimates faster, eliminate re-entry, and deliver a more transparent experience that expedites customer approvals.
