Why Your Auto Repair Shop’s ARO Isn’t Growing (and How to Fix It)

Average repair order (ARO) — the average amount an auto shop's customers spend per visit — is a crucial indicator of your shop's financial performance. A high ARO indicates technicians are effectively diagnosing and flagging needed repairs. It also reflects the skill of your service advisors, who present technicians' recommendations and build customer relationships that lead to the "yes."

If you're struggling with an ARO plateau, the problem probably isn't your customer count or a variable cost issue. A stalled ARO usually indicates missed opportunities between the bay doors and your service counter, where customers decide whether to proceed with the suggested repairs.

This guide will help you understand ARO through a customer acquisition and retention lens. You'll learn how to build key skills in your team and implement the procedures that boost repair order value.

What Is Average Repair Order (ARO)?

A shop's average automotive repair order is its total revenue, including parts and labor, divided by the total number of orders. It's a key profitability metric because it shows how well you're leveraging the customers that walk through your door. 

Increasing your ARO doesn't raise your fixed costs and can help you cope with rising variable costs. And with the national average price per part up 6.6% year-over-year and labor up 3.1%, according to a 2025 report, increasing your ARO is more important than ever. 

The most common ARO range nationwide is $500–$749, according to the most recent publicly available data from PartsTech. The second most common range is $250 to $499. 

Whether that's "good" for your shop depends on your service mix, location, and shop size. Some shops may fall within the lower range and be doing well for their area. It's more important to look at whether your number is trending upward. If it's not, the first step ist o ask why.

Common Reasons Your ARO Isn't Growing

Before addressing your average repair order value, you need to identify what's holding it back. Typical culprits include:

• Inconsistent inspection processes: Unless you conduct a multipoint inspection on every vehicle, service needs go unnoticed, leaving money on the table.
• Weak service recommendations: To maximize conversions, service advisors need to present findings confidently and persuasively.
• Lack of follow-up on declines: If your shop doesn't contact customers to recommend previously declined work, you risk losing them to the competition when they need it.
• Low customer trust: When you don't have established trusting relationships with customers, they're more likely to decline suggested work.
• No upsell or add-on strategy: The most reliable way to break an ARO plateau is with a consistent approach to presenting services.

Once you've identified what's holding you back, you can start to develop a strategy. For most shops, the fix is rooted in customer communication.

How to Increase Average Order Value

The best way to increase your average repair order value is to implement a complete, end-to-end cross-selling and upselling system. It should be persuasive but not pushy, and rooted in a great customer experience.

Make Multi-Point Inspections Non-Negotiable

In a market where 41% of vehicles are overdue for critical maintenance, you don't want to miss any opportunity to identify needed repairs. That's why it's so important to standardize the multipoint vehicle inspection for every car, every service, every time. 

A multipoint inspection can turn a $30 oil change into a $500 brake job, simply by providing a legitimate repair need for service advisors to suggest. It's the foundation of ARO growth, and it's easier than ever to conduct and track, thanks to digital vehicle inspections (DVIs).

DVIs let your technicians easily document and photograph the targets of needed repairs. Those photos can significantly increase approval rates, with one DVI provider claiming a 45% increase in client ARO.

Train Service Advisors to Upsell and Cross-Sell

If your goal is to increase the value of your repair orders, ensure your advisors have strong customer communication skills. There's a fine line between informing a customer of what they need and pressuring them, and many service advisors can easily cross it.

The best approach is to walk customers through the results of their inspection, with driver-focused language and clear communication.

Have them explain why the repair is necessary, emphasizing safety and peace of mind.

Send Vehicle Service Reminders Via Text or Email

Keeping your service pipeline full is the first step to a higher ARO. You can't run a multipoint inspection or explain needed repairs if a customer forgets to bring their car in, and vehicle service reminders help to solve that problem. 

Scheduling software makes it easy to send engaging reminders, and your staff doesn't need to spend hours on the phone. Optimize Digital Marketing has partnered with AutoOps to offer convenient booking management, which sends reminder messages based on customers' vehicle histories. 

AutoOps makes it easy to reduce no-shows with appointment reminders. Clickable CTAs let customers schedule appointments directly from the text (SMS) message or email, so they don't have to pick up the phone. They appreciate the convenience, which boosts satisfaction and aids customer retention.

Follow Up on Declined Services

As a maintenance professional, you know the risks of deferred car maintenance. You understand that saying no to a brake pad replacement can increase the customer's repair costs at best, and cause an accident at worst. You've seen a seemingly small component cause a system failure.

Even if customers understand those consequences in theory, sticker shock can make them say
"no" when they're standing at the counter. Following up on that declined work is a valuable way to remind them of the importance of those fixes.

It's also one of the simplest and lowest-effort ways to grow your ARO.

The first step is to record the declined recommendation in your scheduling software. You'll need compelling text messages or emails that will automatically send after a set period, encouraging the customer to get those repairs taken care of. Be positive and supportive, but remind them that timeliness is important.

Not all customers will respond to the first message. It helps to text them with a second, and even a third, follow-up, with a link to schedule an appointment. This SMS marketing tactic is immediate and convenient enough to overcome objections.

Bundle Value-Added Services

Bundled service packages are a tried-and-true strategy in auto repair. They improve operational efficiency, boost your ARO, and make maintenance more convenient for your customers.

The options go far beyond the standard oil change and tire rotation. Get creative and think of what would benefit customers in different scenarios. Possibilities include:

• Safety bundles: Brake inspection, tire rotation, battery test, and fluid level check
• Winter prep bundle: Oil change, tire swap, battery check, wiper blade replacement, and antifreeze fill
• Pre-road trip bundle: Heat and A/C inspection, tire rotation, fluid and belt check, and battery test

Customer-centric presentation is everything. You want car owners to see these bundles as convenient time-savers, not sales pitches.

Emphasize the importance of routine maintenance and the benefits of getting everything done at once. When customers feel the package is in their best interest, it's great for customer retention and repeat business. 

Track ARO and Adjust Accordingly

ARO is one of a shop's most important performance metrics. If you don't already, you'll want to start reviewing it alongside other key performance indicators (KPIs), including car count and gross profit.

Tracking ARO helps you to separate profitability from volume. It prevents you from making common mistakes, such as assuming more service activity makes you more profitable. More cars may not mean more revenue, but ARO dials into how customers are truly spending.

A detailed ARO analysis can also tell you which advisors, timeframes, and service bays are doing well or underperforming. If you're looking to build a successful automotive strategy in 2026, you don't want to miss incorporating it.
