None of these are dramatic. That's why they survive — each one costs an hour here, a margin point there, until the month ends a thousand dollars lighter than it should have. The five leaks, and the free fix for each:
1. The mid-job supply run
Drive, counter line, drive back, re-setup: 60–90 minutes gone because a $15 part wasn't on the truck. Two a week is a full billable day a month. The fix is a reorder-point system — every part has a minimum, hitting it triggers the order that day. Our free Truck Inventory Manager runs the whole system with one tap per part used.
2. Quoting from memory in the driveway
"Uhh, probably around $350?" costs you twice: underquotes eat margin, wobbling numbers erode trust. A quote with your company header, line items, and a signature block closes at a different rate than a number said out loud. The free Quote Builder makes one on your phone in two minutes, with real part costs pulled from a live catalog.
3. Never tracking your win rate
If you don't know whether you close 40% or 75% of quotes, you can't price rationally. Tag each quote Sent, then Won or Lost — the Quote Builder computes your win rate and won-value automatically. Two weeks of data changes how you price.
4. Flat markup on everything
Marking up a $200 motor and a $12 sensor the same ×2 leaves money on both. Cheap parts carry ×3 easily; big-ticket items win jobs at ×1.5. The markup presets exist for exactly this — reprice a whole quote in one tap and watch the margin line while you do it.
5. Whiteboard inventory
The note that doesn't get written at 5 PM becomes the empty bin on a rooftop Thursday. A system only works if updating it costs one second at the moment of use — that's a tap, not a marker.
