A repair order is the backbone of every job in your shop. When the workflow is consistent, cars move through the bays faster, customers know what they are paying for, and technicians spend less time asking questions. When it is not, work gets started without approval, parts arrive late, and invoices do not match what the customer expected. This guide walks through each stage of the repair order life cycle and what should happen at each one.
What are the stages of a repair order?
A repair order typically moves through eleven stages: check-in, concern, inspection, estimate, authorization, parts, labor, quality control, invoice, pickup and follow-up. Not every job needs every stage in full, but skipping one is where most disputes, delays and comebacks start. Using the same sequence for every vehicle makes the process teachable and measurable.
| Stage | Main owner | Output |
|---|---|---|
| 1. Check-in | Service advisor | Customer, vehicle, mileage, VIN, condition notes |
| 2. Concern (the first C) | Service advisor | The customer’s complaint in their own words |
| 3. Inspection and diagnosis | Technician | Cause, findings, photos, recommendations |
| 4. Estimate | Service advisor | Priced lines for parts and labor |
| 5. Authorization | Customer | Recorded approval of specific lines |
| 6. Parts | Parts person or advisor | Parts ordered, received and allocated |
| 7. Labor and correction | Technician | Work done, time recorded, correction notes |
| 8. Quality control | Lead tech or foreman | Checklist passed, road test where needed |
| 9. Invoice | Service advisor | Final invoice matching approvals |
| 10. Pickup | Service advisor | Explanation, payment, keys returned |
| 11. Follow-up | Service advisor | Satisfaction check, declined-work reminders |
What should happen at check-in?
At check-in, capture the customer, the vehicle and its condition accurately before anything else. Confirm contact details, record mileage, decode or verify the VIN, note existing damage, and agree on how the customer wants to be contacted for approvals. A clean check-in prevents most of the confusion that shows up later in the job.
A practical check-in checklist:
- Confirm the customer’s name, phone and preferred contact method.
- Record odometer mileage and fuel level.
- Capture the VIN and check the decoded year, make and model match the car in front of you. VIN lookup does this in AutoShop POS.
- Walk around the vehicle and note visible damage, ideally with photos.
- Pull up vehicle history to see past work and open recommendations.
- Agree on a promised time and whether the customer is waiting or leaving the car.
How do you write the 3 Cs: concern, cause and correction?
Write the concern in the customer’s words at check-in, the cause in the technician’s words after diagnosis, and the correction once the repair is done. Each repair line should have all three. Together they explain why the work was needed, which builds customer trust and helps with warranty claims and future diagnosis.
Concern
Record what the customer experiences, not your guess at the fault. Ask when it happens, how often, and under what conditions. “Squeal from front when braking, worse in the morning” is far more useful than “check brakes”.
Cause
The technician records what testing or inspection found. Be specific: “Front pads at 2 mm, wear indicators contacting rotors” tells the customer and the next technician exactly what was wrong.
Correction
Record what was done: “Replaced front pads and rotors, cleaned and lubricated slides, road tested, no noise.” If the correction differs from the original estimate, note why.
How should the inspection and estimate stages work?
The technician inspects and diagnoses, records findings with photos and notes, and flags each item by urgency. The advisor then turns those findings into a priced estimate with separate lines for each repair. Keeping inspection and estimating as two distinct steps stops work from starting before anything has been priced or approved.
Good practice for the estimate:
- One repair per line, each with its own parts and labor, so the customer can approve some and decline others.
- Urgency labels such as safety, soon and maintenance.
- Photos attached to the lines they support.
- Diagnostic time shown separately if it is being charged.
Estimates in AutoShop POS are built from the same lines that later become the invoice, so nothing has to be retyped. For more on getting estimates accepted, see how to get more estimates approved.
Why does authorization need to be recorded?
Recording authorization protects the shop and the customer. It shows exactly which lines were approved, for how much, when and by whom. If there is a dispute at pickup, a dated record of approval settles it quickly. Some jurisdictions also have rules about written estimates and consent for auto repair, so check what applies to you.
What to capture for every approval:
- The lines approved and the lines declined.
- The approved total.
- The date and time.
- The method: signature, written message, or phone call noted by the advisor.
- Who gave the approval, if not the vehicle owner.
Declined lines should not disappear. Save them on the vehicle as recommendations so they can be raised again later.
How do parts and labor stages fit together?
Order parts as soon as the lines are approved, then schedule labor around parts arrival. A technician who starts a job and then waits for a part loses billable time and ties up a bay. Allocating received parts to the repair order and recording labor time against each line keeps the job moving and the costs visible.
Parts
- Check stock first, then order what is missing.
- Note the supplier, cost and expected arrival on the line.
- When parts arrive, check them against the order before the technician starts.
Labor
- Assign each line to a technician.
- Record time on and off the job, even roughly, to measure efficiency.
- Add correction notes before closing each line.
What does a good quality-control check include?
A quality-control check confirms the work was done correctly and the car is ready to go back to the customer. It should follow a written checklist: approved lines completed, fluids and fasteners checked, warning lights cleared, no tools or debris left behind, and a road test where the repair affects driving. It is the cheapest way to prevent comebacks.
| QC item | Example check |
|---|---|
| Approved work complete | Every approved line has a correction note |
| Fasteners and torque | Wheels and critical fasteners torqued to specification |
| Fluids | Levels checked, no leaks under the vehicle |
| Warning lights | Codes cleared and dash checked after restart |
| Road test | Driven where the repair affects brakes, steering or drivability |
| Cleanliness | Seat covers and floor mats removed, no grease on interior |
How do invoice, pickup and follow-up close the loop?
The invoice should match the approved lines exactly, with any changes already approved and recorded. At pickup, explain what was done, show the old parts if the customer wants them, and remind them of any declined work. A follow-up message a few days later checks satisfaction and keeps the next visit in view.
At the invoice and pickup stage:
- Compare the invoice with the approvals before printing or sending.
- Explain the work in plain language using the correction notes.
- Take payment and record the method.
- Hand over keys and paperwork, including warranty terms.
- Mention declined recommendations and when they should be looked at again.
Parts and labor invoicing turns the approved estimate into the invoice, and the declined lines stay attached to the vehicle for follow-up.
How do you know the workflow is working?
Track a few simple measures each month and look for trends. If cars sit waiting for approval or parts, the bottleneck is visible. If comebacks rise, look at quality control. A consistent workflow is what makes these numbers meaningful in the first place.
Useful measures:
- Time from check-in to estimate sent.
- Time from estimate sent to authorization.
- Share of estimate value approved.
- Repair orders reopened as comebacks.
- Declined recommendations later approved.
A repair order workflow does not need to be complicated, but it does need to be the same every time. Write it down, train every advisor and technician on it, and let your work orders system enforce the order of the steps.
