Is my real problem not enough leads, or not enough capacity?
Check three things: your booking rate as call volume rises, how far out your first available appointment sits, and how much of your technicians' day is billable. If booking rate falls inside a single source while volume climbs, and first-available keeps sliding, you are capacity limited and more advertising will make it worse. If capacity sits open and calls are scarce, the constraint is demand.
Why the question gets answered wrong
Both constraints produce the same headline symptom: revenue that will not grow. Marketing sees flat revenue and proposes more spend. Operations sees a full board and proposes more technicians. Both are expensive, and one of them is wrong.
Three signals that separate them
- Booking rate within a source. Hold the source constant and watch booking rate as volume rises. Falling booking rate on the same source is a saturation signal. If instead the mix shifted toward a weaker source and each source held its own rate, that is a demand-quality story.
- Days to first available. Track this daily by job type, not weekly. A first-available date that keeps sliding out is the cleanest capacity indicator in the business, and it moves before revenue does.
- Billable share of the technician day. If crews finish early, the constraint is not capacity even when the board looks full. A full board with idle afternoons usually means the schedule is padded, not saturated.
The mixed case, which is the common one
Most companies are capacity limited on two or three high-demand job types and demand limited on everything else. Averaged together the signals cancel out and the business looks balanced. Segment by job type and the picture is usually stark: emergency work booked out for days, while installs and lower-urgency work have open slots all week.
That diagnosis changes the marketing plan more than the staffing plan. It argues for shifting spend toward the categories with open capacity rather than bidding harder on the categories already turning customers away. Joining campaign data to the actual schedule is what makes that shift possible to justify.
What to do while you decide
Capacity takes months to add. Hiring, training and a technician who is productive on their own are separated by a long lag, and the season will not wait. In the meantime the levers are shorter: tighten arrival windows, move non-urgent work into the shoulder hours, reduce return trips, and stop advertising into categories with no slots.
The measurement side is worth building first regardless. If first-available, billable hours and booking rate are not reported together every morning, you are re-arguing this question every quarter from memory. That is exactly what daily briefs are meant to end.
