Reading the ARO Gaps Among Your Shops

Your locations don't have an ARO problem. They have a consistency issue.

If you run more than one shop, you have a number you probably don't look at often enough: the distance between your highest-ARO location and your lowest. That spread isn't a meaningless number. It's a diagnosis — and it's usually pointing at something you can fix this quarter.

Seeing one shop consistently post a higher average repair order (ARO)the average dollar amount per repair order — while another lags behind, month after month, tells you something useful and fixable — that the two shops aren't actually running the same playbook.

When identified, an ARO gap points directly at where revenue is leaking and which location can improve its bottom line. Here's how to read it, and how to close that gap.

What ARO by location actually measures

ARO is your total sales divided by your car count. On its own, a single shop's ARO tells you how much revenue you capture per vehicle. Compared across locations, ARO becomes a relative measure. It shows you which shops are upselling the customers they already have, and which ones are letting opportunities walk out the door.

That distinction matters because car count and ARO are different levers. A location can be busy and still underperform on ARO. When two of your shops see roughly the same number of vehicles but post meaningfully different ARO, the busier-but-lower shop isn't short on demand — it's short on execution somewhere between check-in and checkout.

Why the same brand produces different numbers

When you standardize on one brand, one sign, and one set of prices, you'd expect performance to converge. It usually doesn't, and the reasons tend to fall into three buckets.

1. Inspections aren't consistent

The digital vehicle inspection is where most ARO is won or lost. A location that completes thorough inspections on nearly every car — with photos and clear findings — surfaces more legitimate work and gives customers a reason to say yes. A location that treats the DVI as optional, or rushes it, never puts that work in front of the customer in the first place. Shops that consistently attach more photos and findings to their inspections tend to post a higher ARO than shops that don't, because customers can see the work rather than just hear about it.

2. Estimating and pricing drift shop to shop

If one location prices a job from an up-to-date matrix and another builds estimates by memory or old habits, you'll see the difference in ARO. The same brake job, quoted two ways, produces two different repair orders. Multiply that across every ticket, every day, at every location, and small pricing inconsistencies become a large revenue gap.

3. Workflow and presentation vary by advisor

How work gets presented — whether declined jobs are captured for follow-up, if good/better/best options are offered, and the customer sees the inspection before the phone call — all of it moves ARO. When those steps live in one advisor's head instead of in a standard workflow, they leave when that advisor does.

How to compare ARO across multiple locations

A useful ARO comparison starts with removing the excuses you can measure. Before you conclude a location is simply in a weaker market, line the shops up on the metrics that feed ARO. When you compare ARO across multiple locations, look at five things:

What to compare across locations

  • Inspection completion rate: what percentage of cars get a full digital vehicle inspection (DVI) at each location.
  • Photos and findings per inspection: whether the shop shows customers the work or just describes it to them.
  • Close ratio: of the work presented, how much the customer approves.
  • Declined jobs recovered: whether declined work is followed up over time or lost.
  • Real-time reporting: whether you can see all of the above per location, side by side, without building a spreadsheet.

Those five inputs are what separate a high-ARO location from a low-ARO one. Walk them in order, per shop:

  • Inspection completion rate — what percentage of cars actually get a full DVI at each location?
  • Photos and findings per inspection — is the low-ARO shop showing customers the work, or just telling them about it?
  • Close ratio — of the work presented, how much gets approved? A low close ratio points at presentation, not demand.
  • Declined jobs — is the shop recovering declined work over time, or letting it disappear?

When you put those side by side, the ARO gap almost always resolves into a specific, coachable behavior at a specific location — not a vague "that store just isn't as good." The lowest-ARO shop with the weakest inspection numbers is usually your single, fastest opportunity because you're not trying to create demand — you're converting cars you already have.

You can't coach a gap you can't see

The hard part for most multi-shop operators isn't knowing that consistency matters — it's seeing the gap in the first place. When each location's numbers live in a separate system, a spreadsheet, or a manager's weekly recap, the comparison is always late and never quite apples-to-apples. By the time you notice a location has slipped, you've lost a quarter.

This is where running every shop on one platform changes the math. Tekmetric gives multi-shop operators multi-location control and real-time visibility: a portfolio-wide dashboard and shop-level reporting that track revenue, ARO, car count, and technician productivity across multiple locations at once. Instead of assembling the picture after the fact, you can see which location is drifting while there's still time to coach it.

"Now I can look at everybody at a glance. I can be in a different state, different city and know exactly what's going on in each location all the time. That's not something I had before."
— Leroy Ingram, Ooroo Auto Care (MSO)

Visibility is only half of it. The same platform lets you standardize the inputs that drive ARO — DVIs, canned and Smart Jobs, pricing matrices, and discounts — across every shop, so your best location's playbook becomes every location's default rather than a secret one store happens to know.

"Seeing [a newly acquired shop] take the shift from what they've always used to Tekmetric and then grow profitability in the same four walls has been phenomenal. Some of them are just exponential."
— Matt Schwab, Clutch Automotive (MSO)

Turning the gap into a plan

Once you can see the gap and its causes, closing it is a matter of focus. A few takeaways:

  • Start with your lowest-ARO, lowest-inspection location. It's the biggest lever to pull and the fastest move to make because the demand is already there.
  • Fix one input at a time. Get DVI completion up first; inconsistent inspections are the most common root cause of a lagging ARO.
  • Make your best shop the template. Standardize its workflows, pricing, and inspection process, then apply them everywhere instead of hoping each store reinvents them.
  • Watch the gap, not just the average. A rising portfolio average can hide one location sliding backward. The spread between best and worst is the number that tells you whether your standards are actually holding.

The gaps among your best and worst shops isn't a verdict on your locations. It's a map. It shows you exactly where the next dollar of ARO is hiding.

More articles

When it comes to starting a business, you have a lot to consider.

How are you going to make sales?

Are your operations in order?

How will you approach legal, HR, and marketing?

But it’s important to not forget about one key part to getting your business off the ground: funding.

You’ll want to be well-versed in what to look for in a potential partnership whether you’re in the startup phase, the expansion phase, or even in a plateau phase.

By better preparing now, you’ll set your company up for future success.

Recently, Prasanth shared his thoughts about different kinds of funding with Texas CEO Magazine. You can read the full piece here, or check out some of the highlights below.

Determine The Right Equity Path For Your Business

The first step for any business owner should always consist of researching and selecting the right method of funding for your company. Once you’re confident in your company’s business model, your company’s current state, and any future aspirations for your company, you’ll want to determine the right equity path that can take your company where you want it to go.

1. Venture Capital

Venture capital is a more traditional route and is optimal for new entrepreneurs. If you have an idea for a potential business venture but aren’t sure exactly what to do with it just yet, venture capital could help you secure funding so that you can bring your ideas to fruition.

With venture capital, your partner will purchase a significant portion of the company, and in turn will offer support and guidance to nurture your company’s growth

2. Growth Equity

If your company has already excelled in the starting phases and needs another boost to continue expanding, you’ll want to consider growth equity—otherwise known as “rocket fuel.” Growth equity tends to be founder-centric and offers more autonomy and room to remain true to your company’s original core values and business model.

3. Private Equity

Companies that have reached the later stages of their business’ lifecycle may opt for private equity.

This route can be a good contender for companies that are at risk of going under due to lack of profits. Private equity can give your company the boost needed to prevent it from closing up shop.

Whoever you choose to partner with will take a large portion of your company’s ownership and will make significant changes to the company. However, the private equity route tends to yield bigger checks.

What Did Tekmetric Do For Funding?

Prasanth knows how important the right funding for your company is.

Prior to 2021, Tekmetric was in the startup and the small business stage, so the initial funding from friends and family was an avenue that worked out really well at the time

After 2021, Tekmetric started to expand exponentially. Tekmetric’s Co-CEOs and Co-Founders Prasanth and Sunil Patel realized that more growth could be possible if they changed from their personal network funding to the growth equity route.

Growth equity provided funding for additional initiatives, such as marketing, product research, and hiring. In turn, Tekmetric was able to pursue the vision that Prasanth and Sunil had outlined during the company’s beginning stage.

Find The Right Partner

You’ll want to be intentional about choosing any of your partnerships as a business owner, especially when it comes to finding the right funding partnerships.

The partner you decide to go with will help determine what your business’ tone and future will be like.

As you’re determining the right partnerships for you, ask yourself 5 questions:

  • Is the partner aligned with my business goals?
  • Do I trust this partner with my team and my business?
  • What will my relationship with this partner look like?
  • How much day-to-day involvement in my company does this partner expect?
  • Does this partner provide a reasonable amount of funding to support my goals?

No matter what equity direction you take, you’ll want to find a partnership dynamic that works for you, your business, and your team. As you’re choosing the right partner, remain transparent about any goals and expectations you have in mind for your company.

You won’t want to choose a partner solely based on numbers. The partnership will be a long-term business relationship—a marriage of sorts—and you should treat the partnership with thoughtfulness and respect.

What Did Tekmetric Do For Funding Partnerships?

At Tekmetric, Prasanth and Sunil knew whichever partner they selected to provide funding would play a significant role in the company’s future, and would have a strong impact on Tekmetric’s overall tone, goals, and growth.

At the time Prasanth and Sunil started looking for partners, Tekmetric was a well-established name throughout the auto repair industry, so they wanted a partner that would work alongside them, not just someone who would give them money and stay at a distance.

Eventually, Tekmetric found the right partner—one who is not only sensitive to the company’s needs but also the needs of Tekmetric’s customers.

Tek-Tip: Always ensure your partnerships are a two-way street.

As an auto repair shop management system, Tekmetric has long realized the importance of mutually beneficial partnerships. We’ve established partnerships along the way with companies like Mechanic Advisor and Advance Auto Parts Pro Solutions to help us better meet our customers’ needs.  In fact, Tekmetric has more than 30 industry partners (and counting) to ensure the most seamless possible experience.

Remain True To Your Business Yourself

No matter the equity path you choose to go or the partnerships you choose to take, you’ll want to stay true to your business’ core values and who you are as a business owner.

Rather than cutting corners, you can opt for the best possible solutions.

Prasanth said it best: financial support and equity can be confusing, and it’s easy to get lost in the numbers and forget why you started your business in the first place. However, the right partner will make all the difference.

After all, if you are putting significant time and effort into your idea, your company, and your team, you should expect a partner who supports your continued success long into the future.

In today’s competitive auto repair landscape, service advisors play a crucial role in customer satisfaction and shop success. Managing customer inquiries, collaborating with technicians for repair estimates and maintaining the shop’s schedule are all keys to successful service writing. However, there is one secret weapon that can take your work to the next level: data. 

Understanding the importance of data can take your customer service from good to excellent, allowing you to serve more customers in less time – without sacrificing quality. By harnessing data, you’ll be better equipped to enhance your customer experience, optimize your workflow and ultimately elevate your expertise as a data-driven service writer.

1. Leverage Your Shop Dashboard to Enhance Customer Experience 

By strategically leveraging digital tools, service writers can use data and analytics to provide a better customer experience. Service writers can shape a customer’s entire experience with the shop simply by monitoring and adjusting to accessible data on their shop dashboard through Tekmetric. Using the shop dashboard, you can control the customer’s repair experience, serving as an intermediary between the technician and the vehicle owner, as well as ensuring the work is completed efficiently and effectively.

For example, you can push repair orders (ROs) forward for your customer by ordering parts in the “parts needed” category. Or, you can build stronger customer relationships while creating opportunities for additional work by checking in with vehicle owners who previously declined jobs, but may need them now. By using the data at your fingertips, you can make decisions in real-time that support your customers and ensure their happiness with the repair. Happier customers lead to more money for the shop – and for your commission.

2. Optimize Your Workflow with Data-Driven Tools

Like waiters in a restaurant, service writers are the “face” of the shop, and often they are the first experience a customer has with the business. Because of this, it’s crucial you have a smooth workflow that keeps you open for customer interaction rather than stuck behind a computer screen. Fortunately, there are tools you can leverage to reduce your manual tasks and keep you free to focus on the more complex, relationship-driven parts of your job.

For example, Tekmetric’s Smart Jobs feature can automate job creation, allowing you to focus less on manual data entry and more on customer interactions. Within one or two clicks, Smart Jobs allows you to build the order, find parts and finalize the estimate without ever leaving Tekmetric. By automating the job creation process, you free yourself up to spend more time speaking to the customer about their needs, concerns and questions without compromising the RO’s accuracy.

3. Utilize Digital Tools to Elevate Your Expertise as a Data-Driven Service Writer

When you learn how to leverage data in your day-to-day role, not only can you better serve your customers and optimize your workflow, but you can become a stronger service writer overall. Data is not just a set of numbers on a screen – it is a tool that can elevate your expertise, setting you up for success both within the shop and throughout your career.

One tool that supports your development as a service writer in addition to the shop dashboard and Smart Jobs is the digital vehicle inspection (DVI). Because only 25% of shops use DVIs, leveraging this digital tool correctly can truly differentiate your shop from others around you. The DVI is more than just a list of repairs; it provides information that can help you provide better service. For example, your interactions with customers might prove that including several images and videos of necessary repairs can help customers better understand what’s happening with their vehicle. If you see on a DVI that images were not included, you can connect with the technician to add them before sending the DVI to the vehicle owner.

You can also go the extra mile to anticipate customer questions and clarify any confusing details with the technician before sending the DVI to the customer. This helps you prepare for customer interactions while gaining more expertise from your technicians. As you grow more in your role, you can utilize different tools like the DVI to perform at a higher level, making you better at advising and growing in your expertise as the shop’s “voice.”

Your Secret Weapon to Successful Service Writing

In a customer-facing role, one of the best ways to elevate your role as a service writer is to use data and analytics. As technology continues to improve, you can leverage your shop’s reports through Tekmetric or its integration to gain a greater pulse of shop dynamics. By using data to drive your role as a service writer, you can improve the customer experience, contribute to a more efficient workflow and grow professionally in your role as a service writer.
