CRM for Contractors: The Complete Guide
What a contractor actually needs from a CRM — leads, estimates, crews, invoicing — and how to set one up in an afternoon.
2026-07-10 · contractors · crm · guides
Most contractors run the business out of a truck cab: leads in voicemail, estimates in a spreadsheet, invoices in QuickBooks, photos in a camera roll. Every handoff between those tools is where money leaks.
What a contractor CRM must actually do
- Capture every lead — calls, web forms, and referrals land in one pipeline with automatic follow-up reminders.
- Estimates that become jobs — price lists and estimate templates that convert to invoices without retyping.
- Crew visibility — who is on which job, with field maps for routing the day.
- Get paid — invoicing tied to the same client record as the original lead.
Why point solutions fall short
A sales-only CRM tracks the lead but loses the job. Field-service tools run the job but ignore marketing and reputation. The stitching — exporting CSVs, re-entering clients — is unpaid admin work every week.

SerapisERP's General Contractor preset turns on exactly the modules a trades business uses: Sales CRM, Calling, Price List, Field Map, Finance, and Reputation — one client record from first call to final review request.
