Diesel shops stay busy. The problem is that busy doesn't always mean profitable. Work gets done before it gets approved. Parts get ordered twice. Fleet billing falls three weeks behind. TMI builds the systems that close those gaps.
Diesel repair is technically demanding work. The business problems aren't technical - they're operational. Work that gets done but not documented. Approvals that come after the job is already finished.
A tech finds additional problems mid-repair and fixes them. No one gets authorization. The fleet manager disputes the invoice. You eat the labor or you fight for three weeks to collect. Either way you lose.
You have six fleet accounts. Invoices go out whenever someone gets to it - sometimes 30 days after the work. Cash flow suffers and fleet managers question line items they can't remember approving. Billing lag is a revenue problem.
Your senior tech orders parts the same way he did 15 years ago - by phone, by memory, from whoever picks up. No price checking. No tracking. No accountability when a part shows up wrong and the job sits for two extra days.
Built for shops running fleet accounts, complex repair jobs, and high-value parts - where every approval, every hour, and every part needs to be tracked precisely.
Supplemental work gets flagged before the tech starts. Digital approval sent to the fleet manager. Work begins only when the approval is recorded. Disputes go to near zero.
Each fleet account has its own history, approval contacts, billing terms, and unit roster. Invoices generate automatically at job close. Billing cycles go from monthly to weekly.
Part requests entered on the work order. Preferred suppliers ranked by price and availability. Orders tracked from PO to delivery. No more lost orders or duplicate purchases.
Labor hours logged per job, per tech. You see actual time versus estimated time on every repair. Over time you get accurate labor standards and you quote more precisely.
Fault codes, inspection findings, and repair notes captured at the job level. Fleet customers get service reports. Your shop builds a defensible record on every vehicle.
Incoming work matched against available tech hours and parts lead times before commitments are made. Promise dates that you actually hit instead of dates that erode trust.
