We built it because nothing else could run our shop
SendWrench was built, tested and run inside a working diesel repair shop. It still is.
The month we finally did the math
Busy every day, booked out for weeks, working overtime, and still behind.
Five technicians, each in the building 160 hours a month. That is 800 hours of paid time. The average technician was billing about 65 of his 160. The other 95 hours were paid for, worked in some direction, and never reached an invoice. We had no idea where they went.
SendWrench was written inside a working diesel repair shop. Busy every day, booked out for weeks, working overtime, and somehow still behind. More technicians. More bays. More trucks in the building at once, and the kind of work that does not fit a template: intricate diagnostics, engine and transmission jobs that live in a bay for weeks, custom builds and fabrication where half the parts are not in any labor guide.
Nothing on the market was built for this
We tried the software everyone recommends. It is generic, one size fits all. It tries to do a hundred things: accounting, tickets, a little of everything, none of it well. It is written for shops turning tickets, get the vehicle in, get it out, move to the next one. That is a real business. It is not this one.
The question we could not answer
Did that technician make money last week?
When we finally forced the numbers out, they were ugly. Five technicians, each here 160 hours a month. The average one was billing about 65 of them. That is 95 paid hours per man, every month, gone, and nothing we ran could say where. In a shop where one job holds a bay for three weeks and a diagnostic can eat a day before anything gets written down, those hours are the entire business.
So we built it
Not as a product. As the thing our own counter needed. Technicians clock onto the job rather than the day. Booked hours sit next to actual hours while the work is happening. Hours billed with no time behind them show up instead of disappearing. Performance pay has real numbers underneath it.
Since we put our own shop on it, our efficiency rating is up at least 25 percent, and it climbs every month.
Why we are selling it
SendWrench does one thing really well: it runs a repair shop. The board, the technicians and their efficiency, the customers and their trucks, the parts, the stocking and the inventory, all in one place. No general ledger, no payroll, no hundred half-features.
It is deliberately narrow. Diesel repair, performance work, custom builds and fabrication, on diesel or gas. It is not for a tire shop doing fifty oil changes a day, and it is not an accounting package. We would rather do one thing properly for shops like ours than ten things adequately for everyone.
What you can expect
Built by users, still
Every change ships into our own shop first. If it makes our counter slower, it does not ship to yours.
We will tell you no
If your shop is not a fit, or something you need is missing, you hear it on the call and not in month two.
No lock-in
Month to month, full data export whenever you want it. We would rather earn next month than trap you in this one.
