Using data-driven intelligence to enhance your automotive service repair business.

Estimating shouldn’t slow your shop down. Yet for many automotive service centres and repair shops, building estimates remains one of the biggest workflow bottlenecks. Technicians wait for approved work before they can begin repairs, while service advisors become buried in administrative tasks instead of helping customers. The result is longer wait times, delayed decisions and a less efficient repair process.

Even a few extra minutes spent building each estimate can add up throughout the day, impacting productivity, profitability and overall shop performance. In many ways, the speed and accuracy of a shop’s estimating process determines the pace for everything that follows.

Common estimating challenges include:

       •      Hours lost building estimates, many of which never convert into sold work

       •      Incorrect labor operations, parts selections or pricing that impact profitability

       •      Missed opportunities to recommend related services or maintenance items

       •      Delayed approvals that keep technicians waiting and bays under-utilized

       •      Inconsistent estimating processes across the service team

In short, estimating can become the very thing that prevents shops from getting work done efficiently.

“Accurate estimating starts with precise data. It requires intelligence rooted in validated automotive information and a deep understanding of how repairs are actually performed in today’s shops.”

Why Data-Driven Intelligence Matters

Accurate estimating starts with precise data. It requires intelligence rooted in validated automotive information and a deep understanding of how repairs are actually performed in today’s shops. That’s where OneFlow Estimator stands apart.

Powered by the Snap-on Digital Engine, OneFlow Estimator applies Snap-on’s proprietary repair intelligence to help shops quickly identify the right labour, parts and related services for each vehicle—reducing manual effort, improving estimate consistency and helping work move forward faster.

OneFlow Estimator replaces guesswork with data-driven intelligence, automatically matching parts, labour, and related services to each quote. The benefits extend far beyond speed. OneFlow helps service writers create accurate, profitable estimates with greater confidence.

Available as an option within the Mitchell 1 Manager SE shop management system, OneFlow Estimator is integrated with OneFlow Inspections to create a connected workflow where digital vehicle inspection findings flow directly into estimates.

The Data Behind Smarter Estimates

The Snap-on Digital Engine brings together multiple sources of automotive repair intelligence, including:

       •      3.3 billion validated repair records

       •      5 million Mitchell 1 labour times

       •      3.5 million OEM parts records

       •      Approximately 470 vehicle-specific repair jobs per VIN

       •      More than 500,000 real-world searchable terms

This matters because estimating isn’t just about generating a list of parts. It’s about understanding the labour operations technicians perform, the parts commonly replaced together, and the maintenance services recommended at specific intervals.

Together, these data assets create a smarter way to build estimates that help shops operate with greater speed, accuracy and confidence.

They also help address three of the biggest estimating challenges shops face every day: the time spent manually building estimates, the profitability lost to incorrect parts and labour selections and missed jobs hiding in plain sight.

Faster Searches. Smarter Results

OneFlow Estimator allows users to search naturally, using the same terminology they would use in everyday conversation.

Instead of navigating through complex menus or remembering exact part descriptions, service advisors can simply type phrases such as:

       •      “Front brake pads”

       •      “30K service”

       •      “Water pump replacement”

OneFlow Estimator then auto-populates the relevant repair information and assembles the estimate using VIN-specific intelligence.

The system can identify and suggest:

       •      Labour times

       •      OEM parts

       •      Related parts

       •      Maintenance services

       •      Fluids

       •      Canned jobs

It can also automatically add recommended labour operations, parts and related services directly into the estimate, reducing manual effort and helping service advisors create more complete, accurate recommendations.

The result is a streamlined estimating process that reduces guesswork, improves consistency and helps shops build estimates faster.

From inspections to approvals

Building an estimate is only part of the process. Shops also need a clear path to customer approval.

The tight integration between OneFlow Estimator and OneFlow Inspections creates a connected workflow where digital vehicle inspection findings flow directly into estimates.

Photos, videos and inspection notes support recommendations, giving vehicle owners greater visibility into needed repairs and helping service advisors communicate more effectively.

When customers better understand the “why” behind a recommendation, approval decisions can happen faster, enabling technicians to get working sooner and returning vehicles back to the road more quickly.

Together, OneFlow Estimator and OneFlow Inspections help shops move seamlessly from inspections through approvals, keeping work flowing and vehicles moving through the repair process.

Estimating, Solved

Ever since Glenn Mitchell—founder of the Mitchell Manuals—introduced the industry’s first Estimator Guide in 1958, estimating has been a fundamental part of automotive repair. While the tools have evolved from printed guides to data-driven solutions, the goal remains the same: helping shops build accurate estimates faster and keep work moving through the shop.

OneFlow Estimator builds on that legacy by combining decades of real-world data with integrated vehicle inspections. The result is less manual effort, greater estimate accuracy and a more efficient process from inspection through approval.

With OneFlow Estimator, shops will spend less time estimating, reduce costly parts and labor errors, and uncover profitable opportunities that might otherwise go unnoticed. The payoff is a faster, more connected workflow that helps keep vehicles moving and profitability on track.
