// 01 — Service Mix

WHAT YOUR REVENUE
MIX SAYS ABOUT YOU

The split between inspection, service, and construction affects scheduling, cash flow, staffing, and predictability. Understand what each category contributes to your business.

01

INSPECTION & TESTING

This is your foundation. Mandatory by code. Annual or quarterly. Customers don't cancel it — they have to do it. It's the closest thing to guaranteed revenue in the trades.

  • Predictable, recurring, and contract-based
  • Low labor intensity per ticket vs. project work
  • Review revenue quality, margin, customer retention, and operating capacity each month.
  • Fire alarm, sprinkler, suppression, extinguisher — the more the better
  • Lock customers in with multi-year agreements whenever possible
02

SERVICE & REPAIR

Reactive revenue triggered by inspection findings or equipment failure. Less predictable than inspection but highly defensible — your existing customers call you first.

  • Follows inspection — deficiencies drive repair tickets
  • Margin depends on technician efficiency and parts markup
  • Same-day or 24hr response capability is a competitive moat
  • Track average ticket size and conversion from inspection deficiency
03

CONSTRUCTION / PROJECT WORK

High revenue, lumpy timing, and variable margins. Important for growth — but dangerous if it dominates your mix. PE buyers discount project revenue heavily because it doesn't repeat.

  • Review revenue quality, margin, customer retention, and operating capacity each month.
  • Job costing is critical — know your actual margin per project, not just the bid margin
  • Use project work to seed inspection contracts: always tie new installs to an inspection agreement
  • Watch your backlog — project heavy companies can look great one quarter and starve the next

Revenue resilience

Build service revenue before construction slows

When borrowing costs rise, financing a new building becomes more expensive. Developers may delay projects, reduce scope, or wait for better economics. A fire contractor concentrated in new construction can feel that change through a thinner bid pipeline, postponed starts, and uneven technician demand.

The operating lesson is to build a customer base in existing buildings alongside project work. Inspection agreements create scheduled customer contact; properly documented repair needs can create service opportunities. Inspection revenue can recur under agreements, while individual repair jobs are generally episodic. Track both separately.

Construction exposure

Review funded projects, start-date confidence, backlog timing, retainage, and customer concentration. A signed project does not always mean crews can start next month.

Inspection continuity

Track active agreements, renewal dates, inspection completion, and lost accounts. Build routes around your technicians' credentials and travel time.

Service follow-through

Turn documented findings into a clearly scoped proposal, assign follow-up, obtain authorization, complete the repair, and close the documentation loop.

Make inspection-to-service conversion a managed process

  1. Capture findings accurately in the field and identify any need for urgent escalation through your established procedures.
  2. Assign an office owner to review the report and prepare the proposal. Measure elapsed time from report to proposal.
  3. Explain the finding and proposed remedy to the customer. Record approval, decline, or the next decision date.
  4. Schedule approved work, confirm completion, and reconcile the invoice to the job record.
  5. Review open findings and overdue follow-ups weekly, with qualified technical staff responsible for technical decisions.
Resilient does not mean recession-proof.

Existing-building customers also face budget pressure. Service growth still depends on pricing, staffing, retention, and collections. Never assume every inspection generates a repair; recommendations must follow actual findings and applicable requirements.

Watch the mix and the cash together

Compare inspection, service, and construction revenue and gross profit each month. Add renewal losses, proposal turnaround, approved-service conversion, receivable aging, and revenue concentration. Stress-test what a delay in your largest construction projects would do to crew utilization and cash.
