Here's a number that stopped me cold the first time I heard it: the average independent auto shop writes 40–60 estimates a month, and closes roughly one in four. That's not a close-rate problem. That's an unfollowed-estimate problem.
If you run an auto repair business, you already know how the math breaks. A customer drops off for a check-engine light. Your tech finds a $1,800 fuel system issue. You write up the estimate, call the customer, explain the findings, and send it over. They say “let me think about it.”
Then what happens?
If you're like most shops — nothing. No follow-up text at 24 hours. No courtesy call at 72 hours. No “hey, do you want me to hold this price through Friday” nudge at a week. The estimate dies silently, and you never know whether the customer took it to a competitor, financed it somewhere else, or just kept driving.
The real cost, worked out
Let's get specific. A shop writing 50 estimates/month at a $950 avg ticket, with a 25% close rate, closes 12–13 jobs and bills roughly $12K.
Now add a simple 3-touch follow-up sequence — one text at 24 hours, one email at 72 hours, one final nudge at a week. Industry data across hundreds of shops shows that moves the close rate to roughly 35%. That's 17–18 jobs, or about $16K.
An extra $4,000/month in revenue from the estimates you're already writing. You're not generating more leads. You're not running more ads. You're just finishing the conversation you started.
Why shops don't do this
Three reasons, always:
- The front desk is already drowning. Someone has to handle walk-ins, tech questions, parts calls, the phone. Nobody has a block of time for “oh yeah, let me text the Johnson estimate.”
- It feels pushy. Shop owners I talk to worry about being the guy who “harasses” customers. Spoiler: a polite text at 24 hours is not harassment. Customers forget. They appreciate the nudge.
- There's no system. If it's not in someone's calendar or automated, it doesn't happen. Not because the shop is lazy — because there are 200 other things fighting for that attention.
What a good follow-up sequence actually looks like
The template that works — across auto, HVAC, plumbing, roofing, any trade that quotes work — is three touches with escalating tone, not three copies of the same message:
Touch 1, ~24 hours: short, casual, reference the specific job. “Hey Mike — just wanted to make sure you got the estimate for the fuel system on the Accord. Any questions?”
Touch 2, ~72 hours: offer value, lower the decision friction. “Holding that $1,847 price through Friday — wanted to let you know we have an open bay Thursday morning if you want to get it in.”
Touch 3, ~7 days: final, low-pressure. “Last nudge on the fuel system quote — happy to answer anything, or close this out if you've decided to wait. No pressure either way.”
That last one is important. The “close this out if you've decided to wait” is what makes it feel like a real conversation, not a dripping marketing sequence. Customers often reply to that one with “actually can I book Friday.”
How we automate this at Corex
Our Auto-Quote Closer module watches for new estimates in your shop management system — Jobber, Housecall Pro, ServiceTitan, or any webhook-capable SMS — and fires the 3-touch sequence automatically. The messaging is AI-personalized to reference the specific job, vehicle, and quote amount. You can approve every message before it sends, or set it to full autopilot after you've watched a few go by.
Setup takes about 48 hours. For most shops, the first extra closed estimate pays for the module for a year.
If you're running an auto shop and you're not following up on every estimate, you're not leaving money on the table — you're leaving it under the lift. Go get it back.
