MAJOR BENEFITS
Estimating is one of the biggest challenges shops face in their daily workflow. The time required for service advisors to build estimates creates a major bottleneck – slowing 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.
Produce estimates based on real repair data – not assumptions – with VIN-specific accuracy grounded in how vehicles are actually repaired in real shops. Built by the company that pioneered shop estimating and powered by the Snap-on Digital Engine, OneFlow Estimator delivers the fastest, most accurate estimating experience in auto shop management.
OneFlow Estimator connects inspections → estimates → approvals → invoices in one seamless workflow. Driven by the Job View suite in Manager SE, OneFlow Estimator + Inspections keeps information flowing automatically at every stage – eliminating re-entry, reducing errors, and keeping every job moving with speed, accuracy and full visibility.
OneFlow Estimator automatically matches labor, parts, fluids and related jobs – uncovering every opportunity and helping you build complete, accurate estimates in seconds.
Accelerate approvals by delivering clear, accurate and transparent estimates that customers can trust. Consistent, data-driven pricing removes uncertainty and builds confidence at every step – helping service advisors explain digital inspection findings more effectively and build stronger customer relationships.
Accelerate digital vehicle inspections (DVIs) with advanced service writing tools powered by the Job View suite. Inspection findings convert directly into estimates, while Job View containers group work into clear, easy-to-understand subtotals that help customers review, approve faster and say yes with confidence.
