Your tech drives fifty minutes across town with a windshield strapped in the rack. He pulls into the customer's driveway, walks up to the car, and sees a rain sensor gel pad behind the mirror. The glass on the van does not have the bracket for it. The job is dead before he opens the toolbox, and the whole morning is gone.
Every mobile auto glass operation knows that drive. The failure did not happen in the driveway. It happened on the phone, days earlier, when nobody asked the one question that would have caught it.
The dead run is the number that should scare you
A missed call costs you a job you never had. A wasted trip costs you a job you already booked, plus the fuel, plus the tech hours, plus the slot you could have sold to someone else, plus a customer who now has to take a second morning off work and is deciding whether you are worth it.
Shops track their close rate obsessively and their dead-run rate almost never. That is backwards. On a mobile route, the trip is the expensive part. Cutting a bad job before the van rolls is worth more than adding a good one to the end of the day.
Almost every dead run traces back to an intake gap. The dispatcher had a name, a phone number, and "cracked windshield on a Honda." That is not enough information to load a van.
The intake that decides whether the trip works
Exact vehicle, down to the trim
"2019 Honda CR-V" is where most intake stops, and it is not sufficient. Trim level changes glass part numbers on a huge share of the market. So does build date on models that changed mid-year.
Get the VIN if you can. A customer standing in their driveway can read it off the base of the windshield or the door jamb sticker in under a minute, and it collapses the entire guessing game. If the caller cannot get to the car, take year, make, model, and trim, then flag the order for a second confirmation before the glass gets pulled.
Sensors, cameras, and anything bonded to the glass
This is the question that saves the most trips, and it is the one dispatchers forget.
Ask what is behind the mirror. Ask whether the car has lane keeping, automatic emergency braking, or adaptive cruise, because a forward-facing camera mounted to the windshield means the job includes recalibration. That changes the part, the labor time, and often whether the job can be done mobile at all, since some OEM procedures call for a controlled indoor setting with specific floor and lighting conditions and a target board at a measured distance.
The same goes for a rain sensor, a heated wiper park area, a heads-up display, an acoustic interlayer, or a defrost grid. Each one changes the part number. None of them are visible from a phone call unless somebody asks.
Recalibration requirements vary by manufacturer and by system, and there is no universal rule you can apply across a lot. What you can do is find out on the call whether the vehicle has the hardware, so the job gets scoped correctly instead of discovered in a driveway.
Damage location and size
Where the break sits and how big it is decides whether this is a resin repair or a full replacement, and those are different jobs with different parts on the van.
Have the caller describe the damage against landmarks: how far from the edge, whether it sits in the driver's line of sight, whether it is a single chip or a crack that has already started to run. Ask them to compare the size to a coin. A dollar bill's width is a useful reference for crack length. Photos texted in before the appointment are better than any verbal description, and most customers will send them if you ask.
Where the vehicle will be parked
Urethane adhesive needs the right conditions to cure. Rain, cold, and high humidity all work against a mobile install, and a windshield set in the wrong conditions is a comeback waiting to happen.
So ask where the car will be sitting. A covered garage, a carport, a driveway, or a street spot under a tree are four different jobs. A garage lets you work through weather that would otherwise cancel the day. A street spot in a downpour is a reschedule, and you want to know that before the van leaves.
Safe drive-away time depends on the adhesive system and the conditions on the day, so use the manufacturer's spec for whatever you run rather than a number you half-remember. The scheduling point is simpler: the customer needs to leave the car alone for a stretch after the install, and if they have to be at work in forty minutes, you have a problem.
Insurance or cash
Insurance jobs need the carrier, the policy number, the deductible, and often a claim opened before the tech arrives. Cash jobs need a quote the customer has actually agreed to.
Sorting this on the booking call keeps the tech from becoming a billing department in someone's driveway. It also flags the jobs that will stall, since a claim that has not been approved is a trip you should not take yet.
Whether the customer will be present
Plenty of mobile glass work happens in an office parking lot while the customer is at their desk. That is fine, and it is often the easiest job of the day. It only works if you know in advance.
Confirm who will be there, whether the keys will be available, whether the vehicle will be unlocked, and whether the tech needs a gate code or a parking pass to reach the car. Confirm that the car will actually be in the spot the customer described, which sounds obvious right up until the tech is circling an office lot with a windshield in the rack.

Routing is a load-out problem before it is a map problem
Mobile glass routing is unusual because the van's inventory has to match the day's stops. Sequencing addresses is the easy half. Each job needs its specific part on board, so the route gets locked once the glass is loaded, and a same-day add-on is only possible if the part happens to be in the rack or the shop is on the way.
Practically, that pushes most shops toward batching by zone and by glass availability together, and toward holding a slot or two open for the chip repairs that need no special part. Repairs are the flexible currency in a mobile day. Replacements are the fixed cost.
Weather sits on top of all of it. A morning of rain reshuffles every uncovered stop, and the calls that follow are a customer service problem as much as a scheduling one. Shops that call ahead and move the job themselves keep the customer. Shops that let the tech show up and turn around lose them.
The phone problem underneath all of this
Here is the structural bind. The person best qualified to run this intake is the person who knows glass, and that person is driving between stops or has a windshield half-set in a urethane bead. He cannot pick up. Meanwhile the caller with a spreading crack is working down a list of shops, and the second one on the list answers.
So the booking calls land while nobody is free to take them, and the ones that do get taken get taken fast and thin, because the tech has ten seconds and grease on his hands. Thin intake is how dead runs get scheduled.
Shops solve this in different ways. Some hire a dispatcher, some use an answering service, some route to a partner shop during install windows. An AI voice receptionist like Answara sits in the same slot: it answers while the tech is driving or installing, and it runs the intake checklist every time, so dispatch gets the VIN, the sensor answers, the parking situation, and the insurance details instead of a name and a callback number.
Whatever picks up the phone, the test is the same. Does the note that reaches dispatch contain enough to load the van correctly? If it does not, the trip is a coin flip.
FAQ
What is the single most valuable question on an auto glass booking call?
Ask for the VIN. It resolves year, make, model, trim, and build details in one field, and it eliminates most part-number guesswork before the glass is ever pulled from the rack.
How do you know if a job needs ADAS recalibration?
Find out on the call whether the vehicle has a forward-facing camera or sensor mounted to the windshield, which usually shows up as lane keeping, automatic emergency braking, or adaptive cruise. The specific recalibration procedure and whether it can be done on site depend on the manufacturer's spec for that vehicle, so confirm against the OEM requirement rather than a general rule.
Can mobile glass work be done in the rain?
Not on an exposed vehicle. Moisture and temperature affect how urethane cures, so uncovered stops get rescheduled. Asking at booking whether the car will be in a garage or carport tells you which jobs survive a wet forecast and which ones you should move before the tech is already on the road.
Should the customer be present for a mobile install?
Often they do not need to be, which is why office lot appointments are popular. Confirm key access, vehicle location, and any gate codes at booking, and make sure the customer knows the car has to sit undisturbed while the adhesive cures.
The shops that run clean mobile routes are not the ones with the best drivers. They are the ones whose phone intake is disciplined enough that the van leaves the shop with the right glass, headed to a car that is where the customer said it would be, parked somewhere the adhesive can actually cure. That work happens before anyone turns a key.
