A driver calls from the shoulder of an interstate. Everyone is fine, the van is drivable, and the other driver's insurance card is a photo on your driver's phone. What happens in the next two hours decides whether that vehicle is back on route in nine days or twenty-six.

Collision work is not mechanical work with different parts. It runs a different sequence, generates different paperwork, and offers its own distinct ways to lose two weeks. A fleet collision repair service exists to run that sequence so your team is not learning it one accident at a time.

Scope note: comparing repair vendors in general, and picking an individual shop, are covered in their own articles on the ServiceUp blog. This one is the collision-specific workflow.

The first two hours

Everything downstream depends on what gets captured at the scene. Put this list on a card in every vehicle.

• Photos: all four corners of your vehicle, the damage close up, the other vehicle's damage, both plates, the scene wide enough to show lane position, and the other driver's insurance card and license.
• The police report number and the responding agency. Not the report itself, which takes days. The number.
• The other driver's name, phone, insurer, and policy number, read back and confirmed out loud.
• Witness names and phone numbers, which are the only thing at the scene you genuinely cannot get later.
• Whether the vehicle is drivable, and whether any airbag deployed. Both change the next decision.

Airbag deployment means the vehicle goes on a truck regardless of how it looks, and it means a much longer parts list than the exterior suggests.

Triage, and the total loss question

Two decisions come before any shop touches the vehicle.

First, drivable or not. A drivable unit with cosmetic damage can keep working while it waits for a shop slot, provided it is safe and legal in your jurisdiction. A non-drivable unit needs its tow destination chosen right now, because vehicles towed to whichever yard was closest accrue storage charges and then have to be towed a second time.

Second, repair or total loss. Insurers apply a total loss threshold, and that threshold is fixed by state law in some states and by carrier policy in others, so it varies. What does not vary is the arithmetic you should run yourself: estimated repair cost plus expected supplements plus rental or spare cost for the repair duration, set against actual cash value plus the cost and the lead time of replacing the unit. On an upfitted van the replacement side is worse than it first looks, because shelving, racks, and partitions have to be transferred or rebuilt and that has its own lead time.

Make that call early. A vehicle that gets torn down, waits on a supplement, and is then declared a total loss has burned three weeks for nothing.

Subrogation, and the money you are owed

When the other party is at fault, subrogation is how your carrier recovers what it paid and how you get your deductible back. It is also where fleets quietly lose money, because the follow-up has no owner.

• Open the claim with the at-fault carrier the same day, not after your repair is finished.
• Keep the loss-of-use claim alive. Rental or spare-unit cost during the repair is recoverable in many at-fault situations and is almost never claimed unless somebody asks for it.
• Hold the documentation your carrier will need: police report number, scene photos, the repair estimate, the final invoice, and dated proof of the rental or the spare.
• Track diminished value where your jurisdiction allows it, particularly on newer units you intend to remarket.
• Give one person the recovery list and thirty protected minutes a week. That is usually the entire program.

Parts, supplements, and where the calendar actually goes

Collision cycle time is mostly waiting, and the waiting comes from three places.

Parts sourcing is the first. OEM (original equipment manufacturer) parts fit and carry manufacturer coverage, and they cost more and sometimes take longer to arrive. Aftermarket parts are cheaper with generally better availability, and fit quality varies by part and by supplier. Recycled assemblies can be the fastest option on an older unit, especially for doors, bumpers, and lamp assemblies, and they arrive with whatever history they arrived with. Decide your parts policy by vehicle age and give it to the shop in writing, because a shop that has to ask you part by part is a shop not working on your vehicle while it waits for an answer.

Supplements are the second. The first estimate is written from what is visible, and teardown finds the rest. Supplements are normal. The damage they do is procedural, because each one restarts an approval cycle, and if your approval takes two days then every supplement costs two days of calendar time and zero hours of technician time.

Sublet is the third. Glass, alignment, ADAS (advanced driver assistance systems) calibration, and sometimes mechanical work go out to a second business with its own schedule. Ask at approval which operations will be sublet and what each one adds to the date.

Put numbers on your own approvals. Twelve collision repairs a year averaging 1.5 supplements each is 18 approval cycles. At two days per cycle that is 36 vehicle-days of pure waiting. At four hours per cycle it is roughly nine. The repair work is identical in both versions.

ADAS recalibration after structural work

This is the step fleets miss most often, and it carries the most liability.

Forward cameras, radar units, blind spot sensors, and parking sensors are mounted to structure, glass, and bumper covers. Any repair that moves what they are mounted to, or changes ride height or alignment, can put them outside specification even when nothing looks wrong. A windshield replacement on a van with a camera behind the glass requires calibration. So does a bumper cover replacement on a unit with radar behind it, structural work anywhere near a sensor, and in many cases a four-wheel alignment.

Three documents belong on the invoice, and you should hold the vehicle until you have them.

• A pre-repair scan recording what was stored before work began.
• A post-repair scan recording that nothing is stored now.
• A calibration report for every system calibrated, static or dynamic, naming the procedure used.

A driver assistance system that was repaired but never calibrated will still appear to work. It will brake late, or read the lane a foot off center. That is a vehicle you are about to put a driver in.

Questions fleets ask after an accident

Does a small dent really need a body shop?

Not always. A cosmetic dent with no paint break and no sensor nearby can wait for a scheduled PDR (paintless dent repair) visit while the van keeps working. A dent in a bumper cover on a unit with parking or radar sensors behind it is a different job, because the sensor mounting is part of the damage whether or not you can see it.

Do I have to use the insurer's recommended shop?

No. A direct repair program shop is often faster on approvals because the carrier already trusts their estimates, which is a real advantage. You still have to confirm they are certified for your platform and can calibrate what your vehicle carries. Upfitted fleet vans are not the volume work most carrier programs are built around.

How long should a collision repair take?

It depends on damage severity, parts availability, and how fast you approve. Two of those three are yours. Ask the shop for an ECD (estimated completion date) at approval and for a proactive call when it moves, and treat a missed date with no call as a shop problem rather than a parts problem.

What happens to upfit equipment and telematics during the repair?

Ask before the vehicle goes in. Shelving, partitions, ladder racks, and telematics units often have to come out for structural or panel work, and putting them back is a separate labor line that gets forgotten. Confirm who does it and that it appears on the estimate.

What to do Monday morning

1. Print the scene checklist above and put a copy in every vehicle. It costs nothing and it has the highest return of anything here.
2. Name the person who approves collision estimates, name their backup, and give both names to your shops.
3. Set an internal approval target of four business hours and start measuring against it.
4. Pull your last three collision invoices and check for a pre-repair scan, a post-repair scan, and calibration reports. If they are missing, ask the shop why.
5. Give one person ownership of subrogation and loss-of-use recovery, with a standing weekly slot on the calendar.

ServiceUp is the agentic repair platform for modern fleets, and collision is where the workflow earns its keep. A repair can be opened by a driver texting a VIN (vehicle identification number) or scanning a QR code from the roadside, and from there agents handle shop routing, estimate and supplement review against your policies, approvals, status, and payment to the shop. Fleets running repairs through the platform see 32% faster cycle times and 21% lower repair costs. More at serviceup.com/fleets.
