1. Capture before you calculate
The best estimators shoot everything: the panel, the crawlspace, the wall you'll fish, the equipment tag. Photos give your future self proof, and give tools like Buildersworkshop enough context to draft a material list you can review instead of build from scratch.
Rule of thumb: 20 photos per job. It sounds like a lot until you compare it to the callback of "wait, what did we quote for the conduit run?" three weeks later.
2. Price labor and materials separately
Blended hourly rates hide margin. Every quote you send should have a materials block (unit cost × quantity × your markup) and a labor block (hours × your rate). When your material vendor raises prices, you can update it in one place without re-quoting last month's jobs.
- Residential service: 15–25% material markup, 4–8 billable hours/day.
- Remodel & GC: 20–30% material markup + 10% contingency line.
- HVAC changeout: fixed labor + equipment + freight, itemized on the quote.
3. Lock in your wholesalers before you bid
Bids are only as accurate as your source of truth for pricing. Save two or three wholesalers per trade, note their pickup hours, and price the top ten SKUs you buy every week. When your quote lands, you can defend the number without a phone call.
4. Turn the estimate into a quote — same day
Speed wins jobs. Homeowners get three quotes; the first professional-looking PDF often wins by default. Send the quote before you leave the driveway.
5. Invoice the moment the job is done
Cash flow is a paperwork problem, not a customer problem. Convert the approved quote into an invoice the day you finish. Attach the "after" photos. Mark it paid and send a receipt automatically the same hour the money clears.
