Compare cost per lead with cost per completed job

Use a funnel that reflects the actual business

A delivered inquiry is a usable contact received by the business. Qualification establishes service fit. Booking records an agreed appointment or job, and completion establishes that the work occurred. Write those definitions before calculating costs. A contact click or platform conversion may represent a different stage, so verify its definition. The owner's acquisition report should not substitute a convenient interaction count for the record of real work.

Choose a comparable acquisition cohort

Associate the advertising spend and inquiries with the same traffic period, then follow those inquiries to their later outcomes. Avoid dividing this month's spend by all jobs completed this month if many came from prior months or other channels. Keep incomplete outcomes and unmatched sources separate. Platform click-date and conversion-time reports can answer different timing questions, so document which view supports the acquisition cohort.

Calculate the stage costs transparently

Divide cohort spend by distinct records at each stage. When a stage count is zero, show the cost as unavailable rather than zero dollars. Do not add stage counts together because the same person or job can appear throughout the funnel. Show qualification and completion rates alongside counts so the owner can locate where suitable demand stops becoming work. Use approximate figures only when labeled and supported.

Investigate the expensive transition

A high cost per qualified inquiry may suggest poor service fit or spam. A high cost per booking after strong qualification may involve pricing, availability, or follow-up. A high cost per completion may involve cancellations or fulfillment. These are hypotheses to investigate with the staff, not conclusions from one ratio. Assign the fix to the actual stage rather than changing keywords every time the final acquisition cost rises.

Bring contribution into the decision separately

Completed-job acquisition cost tells you what advertising cost per piece of work; it does not tell you whether that work was profitable. Compare variable contribution after fulfillment and advertising, with fixed overhead shown separately. Check service mix and job size. An expensive acquisition cost can be viable for one service and unsustainable for another, but do not justify it with speculative repeat value or fabricated industry benchmarks.

Review mature outcomes and definition changes

Update pending bookings after enough time for the normal service cycle. Record qualification-rule changes, staffing issues, and missing source attribution. Compare consistent cohorts rather than blending unfinished and settled work. The final report should help the owner choose a specific response: improve request fit, repair follow-up, reduce cancellation, change the offer, or reconsider spend based on completed-job economics.

Worked example: illustrative figures

For example, a $600 acquisition cohort produces 30 delivered inquiries, 15 qualified inquiries, 10 bookings, and 8 completed jobs. Costs are $20 per delivered inquiry, $40 per qualified inquiry, $60 per booking, and $75 per completed job. Qualification is 15 ÷ 30 = 50%; booking among qualified inquiries is 10 ÷ 15 = 66.7%; completion among bookings is 8 ÷ 10 = 80%. These stages overlap and must not be summed into 63 customers. Contribution and fixed overhead need separate analysis.
