Your customers always know. Your whole service department always knows.
WrenchWrite is the service communication platform that reads your DMS, keeps every repair order moving, and updates the customer automatically — in their language — before they ever think to call.
Built for dealership service departments. Read-only to start — your DMS stays the system of record.

The Problem
The silent wait
Customers don't hate the repair. They hate not knowing. Every unanswered question becomes a phone call, every phone call becomes phone tag, and every stalled approval leaves a finished car sitting on your lot while its owner sits in the dark.
“Is my car done?”
The ringing phone
Your advisors spend their day answering status calls instead of selling work. Every "just checking in" call is a customer who should have already known.
Approval by phone tag
The stalled approval
A technician finds the work. Then the RO waits — on a voicemail, a callback, a customer who can't picture what they're approving. Bays stall. Clocks run.
Ready car. Silent lot.
The silent waiting room
The car is washed and parked. The customer doesn't know. It sits — taking up space, aging on the lot, and teaching its owner that your store doesn't communicate.
The Platform
One live picture of every repair order — for the whole store
WrenchWrite sits on top of the DMS you already run and turns repair-order status into communication: automatic for the customer, obvious for the advisor, the technician, parts, and the manager.
Every DMS, one language
Each DMS names repair stages its own way. WrenchWrite normalizes them into one status model, so a promise time means the same thing on every screen in the store. Built to work with:
Automatic updates, in their language
Check-in, diagnosis, approval, in-progress, ready — the customer hears about each one by text the moment it happens, written the way they'd write it. No app to download, no portal password.
Approvals on the phone, itemized
The customer sees each recommended job as its own line — what it is, why it matters, what it costs — and approves or declines line by line. The answer lands on the RO and the customer gets a confirmation. No phone tag.
Walk-arounds, both directions
Technicians send photo and video walk-arounds so customers see the worn part with their own eyes. And when a customer has a concern, they send their own video or voice note straight to the technician's job card — the noise, the rattle, the exact worry, on the record before the car is even racked.
Labor hours & technician efficiency
Booked hours, clocked hours, and efficiency per technician and per job — visible while the day is still fixable, not in a report next month. Promise times and dispatch decisions run on real pace, not hope.
Pay-by-text & the road to sales
The invoice arrives by text; the customer pays from the couch and pickup takes minutes. And when a repair stops making sense against the car's value, WrenchWrite hands the customer to sales — and tracks the deal. (See Equity Moment, below.)
Integration via PBS's Partner Program — preliminary review in progress. WrenchWrite is an independent platform built to work with the DMS providers named above; no partnership or endorsement is claimed.
The Four
Four things no other platform in your store does
Plenty of tools send texts. These four are why WrenchWrite exists.
The Promise Engine
A ready time isn't a guess or a pad — it's calculated from the job itself: the labor guide, this technician's actual pace, the shop's live load, and when the parts really land. Advisors promise from math, not optimism.
And when reality moves — a part slips, a job grows — the Promise Engine warns the advisor before the promise breaks, while there's still time to call the customer first.
The customer never hears bad news late, and never hears it first.
The Bay Speaks
Technicians don't type. They talk. A tech dictates findings at the car — "front pads at two millimeters, rotors scored" — and WrenchWrite translates it, cleans it into plain customer language, and puts it on the record.
The advisor gets a write-up that's already written. The customer gets an explanation they can actually understand. The RO gets a paper trail that was never a burden to create.
The person who saw the problem explains the problem — in thirty seconds, by voice.
The Equity Moment
When a repair estimate crosses 20% of the vehicle's value, WrenchWrite recognizes the moment for what it is: this customer may be better served by a different car. Sales gets the handoff — warm, informed, and with the service story attached.
If the customer buys, the front gross lands on a scoreboard the whole store can see: revenue the service lane produced. The service department stops being a cost center in the principal's eyes and becomes a pipeline.
"Service lane produced $X in front gross this month" — said with live numbers.
Meet Your Mechanic
Customers hand their keys to a stranger. WrenchWrite introduces them instead: the technician's name, photo, certifications, and years on the brand — delivered with the first status update, before the first recommendation ever arrives.
An approval request from a person you've met reads differently than one from a phone number. Trust stops being a slogan and becomes an introduction.
People approve work from people. WrenchWrite makes sure they've met.
The Pilot
One store. Thirty days.
No rip-and-replace, no contract to get started, no risk to your DMS. The first partner store pilots free — we earn the second month with numbers.
-
1
Start read-only
WrenchWrite reads repair-order status and writes nothing back. Your DMS remains the system of record, untouched. If it ever stops helping, you unplug it and nothing is broken.
-
2
Or start with no integration at all
Manual mode runs the full customer experience — updates, approvals, walk-arounds, promises — with advisors and techs moving jobs on big, simple buttons. No DMS connection needed on day one.
-
3
Run it for thirty days
One store, your real customers, your real advisors. We watch the same board you do, every day, and tune the messages and promise math to your shop's pace.
-
4
Judge it on the scoreboard
At day thirty we sit down with the numbers together. If they don't make the case, the pilot ends — and the numbers were the argument either way.
What we measure
- Approval response time — how fast customers answer an itemized approval versus a voicemail.
- Promise accuracy — cars ready when promised, and warnings issued before a promise slips.
- Inbound status calls — the "is my car done?" volume on your advisors' phones.
- CSI-style follow-through — post-pickup review requests, with low scores routed privately to management first, never straight to a public page.
- Service-to-sales gross — deals the service lane handed to sales, tracked to the sale.
WrenchWrite wasn't designed in a software office. It was designed by someone who has stood on the service drive at 7 AM, run the parts counter, worked the sales desk, and answered BDC phones — and who has watched the same communication failure cost customers from every one of those chairs.
