3 Ways to Maximize Auto Repair Shop Profitability

Every vehicle that rolls into your shop is an opportunity to protect a customer's family, uncover real problems before they become roadside emergencies, and build the kind of trust that earns repeat business—but only if your team catches what matters every time.

A consistent inspection process is how shops do that. And when you pair it with the right tools, it pays off: Tekmetric shops using Digital Vehicle Inspections (DVIs) average $741 per repair order, compared to $612 without them.

Below, you'll find a downloadable 100-point vehicle inspection checklist, a breakdown of what every technician should check, and an overview of how digital vehicle inspections can sharpen your workflow.

What are digital vehicle inspections (DVIs)?

Paper inspection checklists worked for decades, but they come with real costs: illegible handwriting, lost sheets, no documentation, and frustrating back-and-forth among the technician, service advisor, and customer.

Digital Vehicle Inspections change that. With Tekmetric, your technicians perform the inspection on a tablet or phone, attach photos and videos of anything that needs attention, and send a vehicle health report straight to the customer's phone.

Here's what that looks like in practice: A technician notices worn brake pads on a 2019 Toyota Highlander. Instead of writing a note the customer may not understand, the technician snaps a photo of the worn pad next to a new one, records a short video, and marks the task red for immediate attention. The service advisor builds the estimate and texts it to the customer. Whether they're an in-store customer in the waiting room or at work across town, the customer approves the job with a digital signature.

Why car inspections matter

Every car owner is counting on your team to catch what they can't see. A consistent inspection process gives your technicians a repeatable way to do exactly that on every repair order, every time.

Inspections also drive revenue. When you document a vehicle's condition clearly with photos and notes, customers understand exactly what their car needs and why. They approve more of the work they genuinely need when they can see the evidence.

Build customer trust with digital vehicle inspections

A great inspection process isn't about checking boxes. It's about giving every vehicle owner a clear, honest picture of their car's condition so they can make informed decisions about their safety and their budget. When your shop pairs a thorough inspection process with a digital tool like Tekmetric's DVI, you give your team the speed and consistency they need and your customers the transparency they want.

Considered the “gold standard” in security compliance, this certification is awarded in accordance with the American Institute of Certified Public Accountants (AICPA) standards for SOC for Service Organizations, also known as SSAE 18.

As one of the first auto repair shop management systems to achieve SOC 2 compliance, Tekmetric is well-positioned to continue safeguarding sensitive information for both auto repair shops and their valued customers.

Maximizing Auto Repair Shop Customer Service: A Guide to Selling Maintenance Work

Training service advisors how to properly sell maintenance work can create more loyal customers.

Drivers typically come in with an expectation of what's wrong with their car, which can make it tricky to sell maintenance work. Drivers might think you're trying to squeeze more money out of them, or may simply have a set budget in their mind and don’t plan on spending extra.

In reality, you're simply trying to go above and beyond and provide them the best service possible. So how do you show that, and which tools will help you transform the way you sell maintenance?

Here’s how to build customer trust while staying true to your auto repair shop’s mission of providing optimal maintenance recommendations.

Why Selling Maintenance Work Can Be a Challenge for Auto Repair Shop Customer Service

According to a survey conducted by AAA, 76% of U.S. drivers said that recommending unnecessary services was the top reason they do not trust auto repair shops. The survey also points out that ⅔ of U.S. drivers have managed to find an auto repair shop that they trust. Whether it’s an independent auto repair shop, or a chain repair shop, trust needs to be at the forefront of the customer experience.

Service advisors may be hesitant to sell maintenance work and only focus on the problem at hand because they don’t want to come off as pushy. But not recommending maintenance work can be a disservice to customers who deserve to know about any and all issues with their vehicle, not just the ones they’ve noticed themselves.

Add a Maintenance-Focused Inspection and Sales Process to Your Auto Repair Shop Customer Service Routine

When it comes to selling routine vehicle maintenance work, it’s important to remember that routine check ups will make a big difference on customer’s cars. Similar to the human body, cars are complex systems. Just like the body has a heart, nervous system, and organs, cars have the engine, the vehicle bus, and the control unit. If one problem is ignored, that could lead to more issues, possibly more serious than the last. For example, if a driver puts off replacing their brakes, it could damage the car’s rotors, which in turn, could lead to loss of braking power. This gets us back to one of the most important benefits of selling maintenance work: it helps your customers stay safe and get as many miles out of their car as possible.

Benefits to Selling Maintenance Work

1. Regular maintenance makes your customers’ lives easier. It prevents your customers from ending up on the side of the road and prolongs their vehicles’ lifespans.
2. Customers save money. Maintenance work can prevent car issues from getting out-of-hand, which may lead to spending more on larger repairs in the future. And who doesn’t want to address maintenance work before it becomes a much larger expense?
3. Providing maintenance inspections helps shops sell more work, which usually means higher ROs and a more profitable repair shop. Also, because maintenance work helps your customers’ vehicles last longer, they’re less likely to buy a new car, which they’ll probably get repaired at the dealership during the first few years.
4. Maintenance inspections help you queue up more work for the future. Even if they decline the maintenance work, you now have a relationship. You can track those declined jobs, and the service advisor and technician can save time figuring out what all might be wrong with the vehicle and resell that work.
5. Customers trust you more. When you provide reliable insights into your customer’s vehicles, your like their go-to car whisperer—a trustworthy person who reminds them to check stuff out on their vehicle before anything bad happens

Maintenance by Mileage

Shop owners, we recommend training your service advisors to check customer mileage at each visit and tracking it in your shop's auto repair shop customer service notes. By keeping track of customer mileage on each vehicle, you’ll be able to recommend maintenance work based on how many miles it has been since their last visit.

Mileage aside, a thorough digital vehicle inspection of all vehicle’s essential components should be performed regularly.
