The Tekmetric Shop Index allows auto repair shops to benchmark themselves against thousands of Tekmetric shops nationwide


Most shop owners have a feel for how their business is doing. They know the slow weeks, the strong months, and whether the bays stayed full. What they often don't have is a good way to compare those numbers against anyone else.

That gap is where opportunity hides — and it's exactly what the Tekmetric Shop Index is built to close.

The Tekmetric Shop Index is a free benchmarking tool that lets you enter your shop's key metrics and instantly see how you stack up against more than 10,000 auto repair shops nationwide. No Tekmetric account is required. No commitments either. It's just an honest look at where your shop stands on the four numbers that matter most.

Top-performing shops track these metrics religiously — and they know exactly where they stand relative to the industry. Here's what each one means, why it matters, and how your numbers compare.

1. Average Repair Order (ARO)

ARO is the average dollar amount of each repair order — total revenue divided by the number of cars you serviced. It's one of the most direct measures of how well your shop is selling and completing work.

A low ARO isn't always a bad sign on its own. But if your car count is healthy and your ARO is lagging, you could be leaving approved work on the table, underquoting, or missing opportunities to present needed repairs. A high ARO, on the other hand, means customers are approving more of the work their vehicles need.

ARO is also the metric most directly tied to your digital vehicle inspection process. Shops that complete digital vehicle inspections (DVIs) consistently — and share them with customers — tend to see higher approval rates and stronger AROs.

2. Car Count

Car count measures how many vehicles you service in a given period. It's the volume side of the revenue equation. ARO tells you how much you make per car; car count tells you how many cars you're making it on.

Both numbers matter. You can have a strong ARO and still struggle to grow revenue if car count is stagnant. And you can have a strong car count but a weak ARO if jobs aren't being sold thoroughly. Top shops keep an eye on both.

Car count breaks down further into new customers and returning customers — a distinction that matters when you're trying to understand whether your growth is coming from acquisition or retention.

"Customers can review inspection results, check estimates, and approve repairs with just a click. Everything is integrated, making our workflow way smoother than before."  — Verified Tekmetric User, G2

3. Parts Margin

Parts margin is the percentage of profit you're earning on the parts you sell. It's calculated as (retail price minus cost) divided by retail price.

This one is easy to overlook, especially if your shop has been using the same parts pricing for years. But small differences in parts margin have a compounding effect across hundreds of repair orders. If your parts pricing isn't keeping up with cost increases from your suppliers, your margin erodes quietly.

Top shops use tiered parts matrices that automatically adjust markup based on part cost ranges, protecting margin without requiring manual pricing decisions on every job.

"We were stuck at a certain level. … Once we made the switch, it just opened doors — payments, parts ordering, inventory — it all became more streamlined."  — Tim Lanier, Lanier Auto Group, Tekmetric Customer

4. Effective Labor Rate

Effective labor rate is the actual dollar amount your shop earns per labor hour — not your posted rate, but what you actually collect after discounts, flat-rate work, and packaged pricing.

A shop might post a $140/hour labor rate but collect significantly less per hour because of how jobs are built, discounted, or packaged. Tracking effective labor rate surfaces that gap and gives you something concrete to address.

This metric also helps you evaluate how well your labor matrix is working or whether you need one.

"I value its cloud-based agility and the way its real-time shop management board eliminates the bottleneck at the service desk … handling parts tracking and labor margins seamlessly."  — Verified Tekmetric User, G2

➡ See how your effective labor rate compares →

So Where Does Your Shop Stand?

These four metrics are the foundation of shop performance analysis. But knowing what they are is only half of it. The other half is knowing how your numbers compare — not to a theoretical ideal, but to real shops in the real industry.

That's what the Tekmetric Shop Index is built to show you. It's a free benchmarking tool that lets you enter your shop's numbers and instantly see how you compare to shops across the country on ARO, car count, parts margin, and effective labor rate. No Tekmetric account is required.

"With the implementation of Tekmetric we have seen a dramatic increase in business and positive feedback from customers."  — Verified Shop Owner using Tekmetric, G2

You can't improve what you don't measure. And you can't prioritize improvements without knowing where the gaps actually are.

Shops use digital vehicle inspections because they solve a trust problem. A customer who cannot see a worn brake pad has to take the service advisor's word for it, and many will not. A DVI replaces a conversation with concrete proof of an issue. That changes the conversation at the counter, and it is why DVIs tie directly to improving your average repair order (ARO), approval rates, and customer satisfaction. Shops also call this a digital multi-point inspection, or simply a digital inspection. The format varies, but the idea is the same: build customer trust by documenting the vehicle's condition in a way the customer can see.

What is a digital vehicle inspection?

A digital vehicle inspection (DVI) is a vehicle inspection performed on a phone or tablet instead of a paper form. The technician walks the car, checks each item on a standardized list, and documents what they find with photos, videos, and notes. Each finding gets a condition rating, usually green for good, yellow for needing attention soon, and red for needing immediate attention. The finished report is sent to the customer by text or email, where they can see exactly what the technician saw and approve or decline the recommended work.

‍

How do you perform a digital vehicle inspection?

Top-performing auto repair shops use a standard workflow for every vehicle, and DVIs are a big part of that.

Here is the process from check-in to approval.

1. The inspection is assigned at check-in

When the service advisor builds the repair order, an inspection template is attached to it. Many shops set a default inspection that is added to every repair order automatically, so nothing depends on someone remembering to add it. The template lists inspection groups, such as brakes, tires, fluids, and exterior, and the individual tasks under each one.

2. The technician performs the inspection on a mobile device

The technician opens the inspection on a phone or tablet in the bay. If they are using Tekmetric digital vehicle inspections, they rate the condition, take photos or a short video, and add a note explaining what they found. Photo markups, such as circling a crack or pointing to a leak, help the customer understand what they are looking at. Because the device is already in the technician's hand, there is no walk back to a shared computer and no paper form to transcribe later.

3. Findings become recommendations

When the inspection is complete, the service advisor reviews the findings and builds the estimate. Inside Tekmetric, inspection tasks are linked to canned jobs, so marking a task yellow or red can automatically add the matching job, with parts and labor, to the repair order. The service advisor adjusts as needed and attaches the inspection report to the estimate.

4. The customer receives the report and estimate

The customer gets a text or email with a link to the inspection report. They see the color-coded list, open the photos and videos, and read the technician's notes. Some systems also attach short educational animations that explain what a component does and why it fails.

5. The customer approves or declines each job

From the same link, the customer approves or declines each recommended job and signs digitally. The service advisor is notified, and approved work moves to the technician. Declined jobs are saved on the vehicle record so the shop can follow up later, rather than losing the recommendation in a filing cabinet.

Which parts of the car should be inspected with a DVI?

A DVI should cover the systems that affect safety, reliability, and performance. Most shops run a core inspection of 20-to-50 points on every vehicle and add specialized templates for specific services such as brakes, alignments, or pre-purchase checks.

Here is a practical list of what a standard multi-point DVI covers or check out our free template.

1. Tires and brakes 

Tread depth on all four tires, tire pressure, brakes, uneven wear patterns, sidewall damage, and the condition of the spare. Tread depth photos with a gauge in frame are among the most persuasive images a shop can send.

2. Fluids 

Engine oil level and condition, coolant, transmission fluid, power steering fluid, brake fluid, and washer fluid.

3. Battery and electrical

Battery test results, headlights, terminal corrosion, cable condition, and alternator output.

4. Belts and hoses 

Cracks, glazing, fraying, and soft or bulging hoses.

5. Suspension and steering 

Shocks and struts for leaks, ball joints and tie rods for play, bushings for cracking, and any abnormal noises noted during the road test. Video is especially useful here because play in a component is hard to capture in a still photo.

6. Exhaust and underbody 

Leaks, rust, hanging components, and heat shield damage.

7. Filters 

Engine air filter and cabin air filter.

8. Exterior and interior

Body damage, wiper blades, warning lights on the dash, and anything unusual the customer should know about. Documenting pre-existing damage at check-in also protects the shop.

Benefits of digital vehicle inspections

The benefits of a DVI show up in four places a shop already measures: average repair order, approval rate, customer satisfaction, and the time it takes to get a vehicle from check-in to payment.

Higher ARO

When customers can see the worn part, they approve the work more often. The inspection also surfaces recommendations a verbal walkthrough would skip, so the estimate reflects what the vehicle actually needs.

Faster approvals 

A photo answers the question the customer would otherwise call back to ask. Fewer "let me think about it" conversations means less time with a vehicle sitting on the lift waiting for a decision.

More trust and better reviews 

The DVI shows the customer what is fine as well as what needs attention. That transparency is what customers mention when they leave a review, and it is the difference between a shop they tried once and a shop they come back to.

A record of every recommendation 

Declined work does not disappear. It stays on the vehicle history, where the service advisor can bring it back up at the next visit or follow up automatically. Over a year, that is a meaningful source of returning car count.

Consistency across technicians and locations 

Every technician works the same template, so the customer gets the same inspection regardless of who is in the bay. For multi-location shops, that consistency is what makes inspection completion and ARO comparable across stores.

How Tekmetric can help

Tekmetric is the all-in-one auto repair platform, and digital vehicle inspections are built into it rather than added through a separate app. When all of that lives in one system, there is no syncing, no re-entry, and nothing to get lost between tools. Tekmetric shops average $612 per repair order, $741 when using Digital Vehicle Inspections, and around $800 when adding MotoVisuals videos to those inspections. 

Here is what shops get with Tekmetric DVI.

Inspections from the mobile app 

Technicians perform the inspection, take and mark up photos, record videos, and add findings from their phone or tablet without leaving the bay. The same app scans VINs and license plates to speed up check-in.

Custom and default inspection templates 

Build inspections with the groups, tasks, and findings your shop uses, and set a default inspection that is added to every new repair order automatically. Multi-location shops can standardize one template across every location.

Color-coded findings 

Green, yellow, and red ratings tell customers at a glance what is fine, what to watch, and what needs attention now.

Canned jobs linked to inspection tasks 

Map canned jobs to inspection tasks so the right job, with parts and labor, is added to the repair order when a finding is marked. Service advisors spend less time rebuilding the same estimate.

Digital authorization 

Customers review the inspection, approve or decline each job, and sign from their phone. Service advisors get notified when a customer views the inspection or estimate.

Declined jobs saved for follow-up 

Work that is recommended but not approved stays on the vehicle record as a future opportunity, and Tekmetric Marketing can automate the follow-up.

Inspection history 

Every inspection is stored with the vehicle, so service advisors can show a customer what was found last visit and what has changed.

DVI Quick Capture 

DVI Quick Capture (in early access) lets a technician capture photos, video, and audio notes during the walk-around while Tekmetric assigns the media to the right inspection tasks and writes the findings in customer-friendly language. The technician reviews and accepts or edits every finding before the inspection is complete.

Key takeaways

A digital vehicle inspection documents a vehicle's condition with photos, videos, and notes, then puts that evidence in the customer's hands so they can approve work with confidence. It works best when it is standardized, performed on every vehicle, and built into the same system that runs the repair order.
