Price per lead is easy to quote because the denominator is whatever the seller calls a lead. It becomes less useful when one source charges for a contact, another produces an appointment request, and your own website records a form submission. The business ultimately needs to understand what it costs to create suitable booked work.
Use cost per booked job as one common comparison, with a clear definition of costs and bookings. Keep inquiry quality, project value, handling effort, and uncertainty beside the number. This is a management measure, not a promise that the lowest ratio always identifies the best source.
Define the booking condition first
Decide what must happen before the business calls a job booked. It might be an accepted proposal, a confirmed service appointment, or another documented event. Different businesses use different stages, so the definition needs to match the work being compared.
Do not count a request for an appointment as a confirmed booking unless that is actually what the process establishes. Keep quotes, accepted work, completed jobs, and collected revenue separate. A source can look stronger or weaker simply because those stages were mixed.
The lead model comparison explains why the provider's billable event and your business outcome are separate. Preserve both in the report.
Set the cost boundary
At minimum, identify the acquisition spending included in the calculation. That may include lead purchases, media, management, and the portion of a landing page or tracking project assigned to the period. If you include internal handling or estimating effort, use the same method across the sources.
The home services marketing cost guide can support the budget conversation. A useful comparison should show the components rather than hide them inside one unexplained marketing total.
For a paid campaign, media and management may be separate. A marketplace purchase may include credits or subscriptions. An owned website may have setup and recurring expenses. None of those models becomes comparable merely by dividing the most visible invoice by contacts.
Use a cohort with time to progress
Group inquiries by when they entered the process and allow an appropriate period for their outcomes to mature. If one source's inquiries are several months old and another's arrived last week, a booking comparison will be biased by timing.
Keep open opportunities visible and state the review date. You can report an early operational view while marking the booked job measure provisional. That is more useful than forcing every unresolved proposal into a win or loss category.
A hypothetical comparison worksheet
- A: current page
- Observe the starting version.
- B: one change
- Compare with the same measurement.
| Measure | Source A | Source B |
|---|---|---|
| Agreed acquisition cost | $2,400 | $2,000 |
| Billable or recorded contacts | 60 | 20 |
| Qualified opportunities | 18 | 12 |
| Booked jobs from the cohort | 6 | 8 |
| Cost per contact | $40 | $100 |
| Cost per booked job | $400 | $250 |
These numbers are illustrative and do not represent provider pricing or typical contractor results. They show that Source A's lower contact price does not produce the lower booking cost in this scenario.
The calculation is acquisition cost divided by booked jobs from the defined cohort. When there are no booked jobs, do not report a misleading zero cost. Show the spending and zero bookings, then explain whether opportunities remain open or the review period is complete.
Add handling effort where it changes the decision
Suppose Source A also requires more office time to clarify requests and more estimator effort on unsuitable work. That cost can matter even if it is not included in the first acquisition ratio. Record it as a separate view or use a consistent allocation method.
The goal is not to create false precision about every minute. A simple distinction between straightforward review, repeated clarification, and substantial proposal effort may expose a meaningful difference. The business can then decide whether more detailed tracking is worthwhile.
Check whether the booked jobs are comparable
Eight short jobs and six larger projects can have different value, delivery costs, and scheduling effects. Review the project mix and the business's chosen contribution measure. A lower booking cost is not automatically better if the resulting work consumes resources the company would prefer to use elsewhere.
Also consider cancellations and rescheduling. Preserve the original booking measure and add a clearly labeled later view. Quietly removing canceled jobs from one source while leaving them in another makes the comparison unreliable.
Keep attribution limits in the report
- Search → guide
- First discovery and useful reading.
- Return → inquiry
- A later visit can lead to contact.
A customer may interact with more than one channel before booking. Google Ads attribution models allocate conversion credit; that allocation does not by itself prove what caused the sale.
Deduplicate the business outcome before adding totals from multiple platforms. Keep known campaign evidence, customer reported discovery, and unknown sources visible. If a source cannot be assigned confidently, state the limit rather than crediting whichever dashboard looks most complete.
Ask the vendor questions the worksheet exposes
If contacts are inexpensive but qualification is weak, review the selected service, geography, and customer expectation. If qualification is healthy but bookings lag, review response, quoting, and the decision cycle. The lead buying questions help distinguish vendor terms from internal responsibilities.
Use the vendor scorecard to record the evidence and next action. The scorecard should explain why a source is being retained, adjusted, or paused rather than simply assigning it a star rating.
Before approving a comparison, ask a second person to trace one booking back to its inquiry and cost period. This small reconciliation can expose duplicate records or inconsistent definitions that would otherwise change the conclusion.
Make a decision that can be reviewed later
A hypothetical owner may decide to retain Source B at its current scope while asking Source A to refine a service category. The decision record should state the cohort, cost method, booking definition, open opportunities, and review date. It should also identify what new evidence would change the decision.
This keeps the comparison practical. The business can pursue better economics without pretending that a small sample establishes a permanent winner or that lead distribution alone determines results.
Request a free marketing audit to review whether your current reports connect acquisition spending with suitable booked work. Bring the available stage counts and cost records so the next scope can address the measurement gaps that matter.
