There is no verified benchmark, and a borrowed one will mislead you. Work it out: add up the minutes one repair order needs at each step when it is done properly, subtract lunch, meetings, phone calls and slack from the advisor's day, weight for your mix of waiters and drop-offs, and divide. Then test the morning rush separately.
Why There Is No Magic Number
Ask around and you will hear a confident number of repair orders an advisor "should" write in a day. We looked for a source and did not find one. NADA Data 2025 reports 16,252 repair orders per average franchised dealership for the year, but it does not report how many service advisors those dealerships employ, so no national ratio can be computed from it. The figures in circulation are rules of thumb handed from one manager to the next.
They also describe different jobs. An advisor in an express lane writing oil changes for waiting customers and an advisor handling diagnostic drop-offs, warranty questions and insurance work are doing different amounts of work per ticket. One count cannot be right for both.
So use a method. It is the same one set out for phone rooms in how many BDC agents a dealership needs: count the work in minutes, count the minutes a person really has, and divide.
Step 1: Minutes per Repair Order, Done Properly
List every step the advisor performs on one repair order and time it. Time the version you want, not the version that happens on a bad Monday. If a proper walkaround takes four minutes, write four, even if today it gets one.
Every figure in this table is an assumption chosen to show the method. None is a benchmark. Stand in the lane with a stopwatch for ten repair orders of each kind and replace them.
| Step | Drop-off, repair or diagnosis (assumed minutes) | Waiter, maintenance (assumed minutes) |
|---|---|---|
| Review the appointment and history before arrival | 2 | 2 |
| Greeting and walkaround | 5 | 4 |
| Write-up, estimate, authorization, promise time | 7 | 4 |
| Dispatch and technician questions | 3 | 1 |
| Review the inspection and build the estimate | 6 | 3 |
| Present findings, record approvals and declines | 7 | 4 |
| Status updates | 4 | 1 |
| Review and close the repair order | 4 | 3 |
| Delivery: explain the work performed | 5 | 3 |
| Notes and next appointment | 2 | 2 |
| Total | 45 | 27 |
The steps are the ones in the service advisor skills checklist. If your total looks high, decide which step you would delete, and ask whether your customers would agree.
Step 2: The Minutes an Advisor Actually Has
A scheduled shift is not capacity. Start with the shift and subtract what is not repair order work. Again, these are assumptions.
- Time at work: 9 hours, or 540 minutes.
- Lunch and breaks: 45 minutes. That leaves 495.
- Huddle, warranty paperwork, chasing parts, the open repair order list: 45 minutes. That leaves 450.
- Phone calls that are not about today's repair orders (appointment requests, price questions, callers transferred from the switchboard): assume 20 calls at 3 minutes each, 60 minutes. That leaves 390.
- Slack. An advisor cannot be scheduled to the minute, because customers arrive early, technicians have questions and the unexpected happens daily. Assume 15% of the remaining time stays unassigned. 390 x 0.85 = 331.5 minutes.
The slack percentage is a management choice. Less slack means more tickets and more waiting. The service advisor time management guide covers how to use those minutes better. This page is about how many there are.
Step 3: Weight for Mix and Divide
Suppose 60% of this advisor's repair orders are waiters in for maintenance and 40% are drop-offs (an assumption; pull your own split from the scheduler).
Weighted minutes per repair order: (0.60 x 27) + (0.40 x 45) = 16.2 + 18 = 34.2 minutes.
Capacity: 331.5 / 34.2 = 9.7. On these assumptions, this advisor can do about ten repair orders a day properly.
Now change one input at a time, holding the rest.
| Change (all figures assumed) | Arithmetic | Repair orders a day |
|---|---|---|
| Base case | 331.5 / 34.2 | 9.7 |
| Someone else takes the 20 phone calls | (450 x 0.85) / 34.2 = 382.5 / 34.2 | 11.2 |
| All drop-offs, no waiters | 331.5 / 45 | 7.4 |
| All maintenance waiters | 331.5 / 27 | 12.3 |
Same advisor, same shift, and the answer runs from about seven to about twelve. That spread is why no single number travels between stores.
Run it backward as well. If this advisor is in fact writing 16 a day, each repair order is getting 331.5 / 16 = 20.7 minutes against the 34.2 it needs. About 13.5 minutes per ticket are going missing. The question is which steps they came out of.
Test the Morning Rush Separately
Daily capacity can look fine while the first ninety minutes are impossible, because most drop-offs want the same early slots. In the example, greeting, walkaround and write-up take 12 minutes for a drop-off (5 plus 7). One advisor can therefore write five drop-offs an hour and no more. If the scheduler lets customers book that advisor every 10 minutes, the sixth customer of the hour is waiting before anyone has done anything wrong, and by 8:30 the walkaround has been dropped to catch up.
Space appointments by write-up time per advisor, not by the shop's hours available. It is the cheapest fix on this page, and it also shortens the line described in how to reduce customer wait time.
Signs an Advisor Is Over Capacity
An overloaded advisor still writes every repair order, because the customer is standing there. The minutes come out of the steps with no customer in front of them.
- Inspections completed but not presented. The form is done and nobody called. This is usually the first step to go.
- No status updates. Customers call in to ask, which adds calls and makes it worse.
- The walkaround disappears after the first half hour.
- One-line repair orders rise on busy days and fall on quiet ones.
- Callers wait. In a CDK Global survey of more than 2,500 service customers (April 2025), 64% booked their appointment by phone, those put on hold waited 8.2 minutes on average, and customers put on hold gave Net Promoter scores nearly 20 points lower than average. In Pied Piper's 2026 Service Scheduling Effectiveness study (6,538 service requests, 33 brands), callers took 66 seconds to reach a service advisor at the average dealership, and 16% could not schedule by phone at all.
The tell is the pattern by day. If an advisor does these steps on a slow Wednesday and drops them on Monday, the skill is there and the minutes are not. Reading an advisor's numbers shows how to separate the two.
What to Do When the Math Does Not Work
Four fixes, each aimed at a different line of the arithmetic.
- An express lane. Move quick maintenance to a dedicated lane with its own writer. The main-shop advisors are left with fewer, heavier tickets, so their count per day falls while the time per ticket finally matches the work.
- Take the phones off the advisors. In the example, 20 calls cost an hour, worth about one and a half repair orders a day. A service BDC, or an outside call center for scheduling and overflow, gives that hour back. The trade-offs are in train the advisors or take the phones off them. Pinnacle sells both routes, through its service BDC training and its outsourced call center for dealerships, so weigh our view accordingly.
- An assistant advisor. Someone to handle status updates, closing and the cashier handoff shortens several rows of the table at once, and it is how many stores grow their next advisor. See hire an experienced advisor or train a new one.
- Appointment spacing. As above. It costs nothing.
Training comes after those, not in place of them. Time management is one of the six fundamentals in Pinnacle's service advisor training, and better habits do recover minutes. But no course adds two hours to a day that is short by two hours. Fix the load first, then train. The Service Advisor Training Resource Center covers what to do next.
Frequently Asked Questions
How many repair orders a day is too many for a service advisor?
Too many is the point at which steps start disappearing: inspections go unpresented, status calls stop and walkarounds are skipped. That point depends on your mix of work and on phone load, so it differs by store and by lane. Time your own steps, do the arithmetic, and compare the result with what each advisor is writing.
Is there an industry standard for repair orders per service advisor?
Not one we could verify at a primary source. NADA's annual data reports repair orders per dealership but not advisor headcount. The figures you hear at meetings are rules of thumb from particular stores with a particular mix. Use them as conversation starters and rely on your own timing.
Should service advisors answer the service phone?
Advisors should take calls about cars they are working on. Appointment requests and general questions can be handled by someone else, and each such call an advisor takes comes out of write-up, presentation or update time. Count a week of calls by type before deciding, because the answer depends on your volume.
Does adding an advisor always fix an overloaded service lane?
No. If the shortage is only in the morning rush, spacing appointments may fix it for nothing. If phones are the drain, moving the calls is cheaper than a salary. And if technicians are the constraint, another advisor will sell work the shop cannot produce. Find which line of the arithmetic is short first.
Summary
There is no verified number of repair orders an advisor should write, because the work per ticket varies too much. Time each step done properly, subtract lunch, meetings, calls and slack from the shift, weight for your mix, and divide. Test the morning rush on its own. When the count an advisor writes is well above what the arithmetic allows, the missing minutes are coming out of inspections and updates, and the fix is the load: an express lane, the phones, an assistant, or appointment spacing. Then train.
