How Much Revenue Is Sitting in Your Service Department’s Forgotten Follow-Ups?

Every service advisor knows how this goes.

A customer declines a brake job. A part has to be ordered. A vehicle needs to come back next Tuesday. Someone asks you to give them a call next week once they’ve checked their budget.

You make a note. You mean to get to it.

Then the drive gets busy. The phone won’t stop ringing, three customers walk in at once, a tech needs an approval, parts are delayed, and another RO needs your attention right now. That follow-up slides further and further down the list.

The opportunity didn’t disappear. Nobody followed up.

So how much money is actually sitting behind those forgotten follow-ups? There’s no single magic number — no credible study says “every missed follow-up costs exactly $X.” But recent dealership data gives us a pretty clear picture of how big the opportunity really is.

There’s More on Every Repair Order Than What Gets Approved

A repair order holds a lot more than the work the customer signs off on that day. During a visit, a customer might decline:

• Brake work
• Tires
• Maintenance
• Suspension repairs
• Fluid services
• Recommended inspections
• Other repairs the technician found

A “no” today isn’t a “no” forever. Most of the time it means not yet. The opportunity is still open — the only question is whether someone remembers to bring it back up.

Customers Decline a Lot of Recommended Work

Industry data cited from the 2025 Carlisle & Company Fixed Operations study reports that service advisors recommend roughly $847 in additional services per repair order, and that customers decline about 62% of those recommendations.

That works out to around $525 in declined work per RO.

Treat that as an industry benchmark, not a promise for your store. But look at what it means at scale. A dealership writing 2,500 repair orders a month would see:

2,500 ROs × $525 = about $1.31 million in declined recommended work passing through the service lane every month.

That doesn’t mean the store is losing $1.31 million. Some customers will come back and approve the work. Some of it isn’t urgent. Some customers will say no for good, and some will get it done somewhere else.

The point is simple: a huge amount of potential service revenue starts life as a declined recommendation. What happens next depends on follow-up.

What Happens When Nobody Calls the Customer Back?

A declined repair can go a few different ways. The customer might call back on their own. They might book it later. They might take it to an independent shop down the street. Or they might just forget about it until something breaks.

You can’t control all of that. But if nobody follows up, you’ve handed the next step over to chance.

And that’s a shame, because the hard part is already done. The technician found the issue. The advisor explained it. The RO has all the details. The only missing piece is the follow-up.

Customers Don’t Always Come Back on Their Own

Customer retention is the other half of the story.

J.D. Power’s 2025 U.S. Customer Service Index found that communication is one of the key drivers of the service experience — including keeping customers informed about their vehicle’s status and contacting them after the visit.

The same study found that 12% of repairs weren’t fixed right the first time. Among those customers, only 50% said they returned or planned to return to the dealership, while 5% went to an aftermarket shop to get it sorted out.

Not every communication miss costs you a customer. But how you communicate is tied directly to how customers feel about your service department — and whether they come back. Follow-up is one of the few parts of that experience you fully control.

What One Lost Service Customer Is Really Worth

A 2026 Cox Automotive study, as reported by Kimoby, found that dealerships leave about $12,000 on the table for every lost service customer.

That number matters because a customer isn’t one repair order. They’re years of oil changes, tires, brakes and repairs.

If someone declines a $700 repair today, the stakes aren’t just $700. If that customer quietly stops coming back, you lose every visit that would have followed.

That’s why follow-up shouldn’t only be about “Did we sell the repair?” It should also be about “Did we keep the relationship going?”

Communication vs. Silence: The Revenue Gap

A 2026 Kimoby analysis looked at 871 dealerships, 16.8 million repair orders and $5.5 billion in customer-pay revenue over the 12 months ending February 2026.

Repair orders that included a digital conversation with the customer averaged $455.08 in customer pay. Repair orders without one averaged $291.12. That’s a gap of $163.96 per RO.

An honest caveat: the report itself calls this a correlation, not proof that communication alone drove the higher numbers. Bigger, more complex jobs naturally create more back-and-forth.

Still, a difference that size is hard to ignore. Communication matters.

The Real Gap: Nobody Tracks What Happens After the RO

Most dealership systems are great at recording what already happened. The RO was opened. The vehicle was inspected. The estimate was built. The work was approved or declined. The RO was closed.

But what about tomorrow?

• The customer who said, “Let me think about it.”
• The car that needs to come back when the part lands.
• The customer who’s expecting an update tomorrow afternoon.
• The declined brake job you should bring up again next month.

Those are future actions. And future actions are exactly where things get lost.

Your Spreadsheet Isn’t the Problem. It Just Can’t Tap You on the Shoulder.

Plenty of advisors keep a spreadsheet for all of this, and honestly, it can work. It’s flexible. You can log RO numbers, customer names, notes and dates however you like.

But a spreadsheet is still just a list. You have to open it. You have to read it. You have to figure out what needs to happen next — and remember to check it in the first place.

When the drive is slammed, “go check the list” is the first thing to get skipped.

The issue isn’t that your spreadsheet is messy. It’s that it doesn’t remind you of anything.

What a Good Follow-Up System Should Actually Do

A useful follow-up system should make the next step obvious. At a glance, it should tell you:

• Which ROs need attention right now
• Which customers are due for an update
• Which customers declined recommended work
• Which vehicles are waiting on parts
• Which vehicles need to come back
• Which follow-ups are due today
• Which ROs are done and can be archived

No digging through yesterday’s sticky notes. You just see what needs to happen next.

Where ROQFLOW Fits In

ROQFLOW was built for exactly this problem.

Scan it. Log it. Let it do the rest.

Instead of treating an RO as something that just gets opened and closed, ROQFLOW helps you keep track of everything that happens around it:

• Repair orders
• Waiters
• Customer updates
• Manual follow-ups
• Automatic reminders
• Vehicles coming back when parts arrive
• Carry-over work when you’re off shift
• Shared ROs across your department

It works on your desktop and your phone, and stays in sync between the two. It doesn’t replace the systems your dealership already uses — it gives you a better way to keep track of the work that still needs to happen.

A Forgotten Follow-Up Is More Than a Forgotten Task

Behind every missed follow-up there’s usually something real: a declined repair, a customer who needs to come back, a car waiting on a part, a customer waiting on a call, a future repair, or a relationship that needs a little attention.

Not every one of those turns into revenue. But every one of them deserves a next step.

And the more ROs you write, the harder it gets to keep all of those next steps straight in your head.

The Question Every Service Department Should Ask

Don’t ask, “How much do forgotten follow-ups cost us?” There’s no universal answer.

Ask this instead:

How much potential service revenue is sitting in our declined work, returning vehicles and open follow-ups right now — and how much of it are we actually working?

That one you can answer. Pull your last 30 days and look at:

1. How many customers declined work?
2. How many need to come back?
3. How many vehicles are waiting on parts?
4. How many customers were supposed to get a follow-up?
5. How many actually did?

Then look at what happened afterward. That’s where your real number starts to show up.

A Simpler Way to Follow Up

You don’t need another complicated process. You need something that makes the next step hard to miss:

1. Capture the RO.
2. Track what happens next.
3. Set the reminder.
4. Make the call.
5. Archive it when it’s done.

A busy service drive doesn’t have to mean lost opportunities.

Frequently Asked Questions

How much declined work is on an average repair order? Industry data cited from the 2025 Carlisle & Company Fixed Operations study puts it at roughly $525 per RO — about $847 in recommended services, with around 62% declined.

How much is a lost service customer worth to a dealership? A 2026 Cox Automotive study, as reported by Kimoby, estimates dealerships leave about $12,000 on the table for every service customer they lose.

What’s the best way for service advisors to track follow-ups? Use a system that shows you what’s due instead of one you have to remember to check. Every follow-up should have a date, a reminder and a clear next step, so nothing depends on memory alone.

The Bottom Line

There’s no credible universal number for how much dealerships lose to forgotten follow-ups specifically. But the data makes one thing clear: a lot of revenue lives in the work that happens after the first repair order — declined repairs, returning vehicles, future service and customer retention.

The money isn’t always lost because the customer said no.

Sometimes it’s lost because nobody asked again.
