Ask what is being sold or counted
The phrase plumbing lead can describe a phone-button click, a received inquiry, a shared contact or a request that has already been checked against your service criteria. Those are different products and different stages of a customer journey.
Before comparing prices, ask what the supplier or report means. Is the contact exclusive under the agreement? Has anyone confirmed service fit? Are repeat contacts counted again? What happens when the request concerns work you do not provide? Get the actual terms rather than filling the gaps with assumptions.
For your own campaigns, inspect the conversion event. Google Ads measures configured actions after ad interactions. A low cost per conversion may refer to an event earlier than a genuine inquiry, so the number needs a clear label.
Choose definitions the office can maintain. An inquiry is a received request about potential work. A suitable inquiry meets your agreed service, property, area and timing criteria. A completed job is work your business has actually delivered. Keep these distinctions visible in the report.
Decide which acquisition costs belong in the calculation
Media spend is useful to track, but it is not always the complete cost of acquisition. Depending on the comparison, management, lead-provider charges, landing-page work and other relevant acquisition expenses may need to be included.
Label the method rather than claiming one version is always correct. A media-only figure can help manage an advertising account. An owner comparing two complete approaches may need a broader cost view. The problem occurs when one side includes costs the other leaves out.
Use the same period for the numerator and denominator. Comparing a quarter of spending with one month of inquiries produces a figure with no clear interpretation. If one-time setup work is included, state how it is being treated so later periods remain comparable.
Do not mix service delivery costs into a lead-cost figure without explaining the method. Those costs matter when assessing job contribution, but acquisition cost and delivery economics answer different questions. Keep the steps clear enough that another person can reproduce the calculation.
Calculate several stages, not one headline number
Use the same acquisition spending to calculate the cost at each meaningful stage. The changing denominator reveals where the business loses progression. It does not by itself establish why that loss occurs.
| Measure | Hypothetical count | Calculation using 1,000 budget units | Result |
|---|---|---|---|
| All received inquiries | 20 | 1,000 divided by 20 | 50 units per inquiry |
| Suitable requests | 10 | 1,000 divided by 10 | 100 units per suitable request |
| Completed jobs | 4 | 1,000 divided by 4 | 250 units per completed job |
These figures are invented solely to show the arithmetic. They are not market averages, expected results or Pulse pricing. Replace every input with your own records before using the worksheet to make a spending decision.
The example shows why a statement such as “our leads cost fifty” is incomplete. It describes one stage and one cost method. The owner still needs to understand whether the suitable work and completed jobs justify the acquisition effort.
Deduplicate contacts without losing useful information
A customer may call, submit a form and send a photograph about the same job. The business needs to retain those interactions, but counting them as three independent opportunities can make acquisition look more efficient than it is.
Use a consistent method to connect related contacts within your approved systems. Keep the original source information where available and identify the underlying opportunity. Do not overwrite the customer's history simply to force the reporting totals to match.
Distinguish repeat contact from repeat business. A later request for a different job may be a new opportunity. Your definition should explain that difference so staff do not make inconsistent choices from one week to the next.
Where attribution is uncertain, retain an unknown category. Guessing a source creates false precision and can push spending toward a channel that did not produce the work attributed to it.
Compare the same work mix
An emergency drain request and a planned installation can have different delivery costs, decision periods and commercial value. A channel attracting one should not be judged against another solely through the average cost of all contacts.
Break down the report by the service priorities that matter to the business. You do not need dozens of categories, but the distinction between materially different work should remain visible. Otherwise, an apparent improvement may simply reflect a shift toward cheaper, less useful requests.
Use actual job economics to assess completed work. Revenue alone does not show what remains after delivering the service. Consider the business's own contribution method, travel and operational demands rather than importing an external benchmark that cannot reflect those conditions.
Do not automatically reject a higher-cost inquiry. It may lead to work the business values, or it may be unsuitable despite its price. The outcome and fit determine the commercial judgment.
Allow open opportunities time to progress
A monthly report can contain inquiries that have not yet reached a decision. Planned projects may need a visit, specification and estimate. If every unfinished request is treated as lost at the reporting cutoff, the completed-job cost can look worse than the eventual result.
Keep an inquiry-date view where practical. Review what happened to the group of requests received during a defined period as they progress. Label which remain open and which have reached a known outcome.
A cash-period view is also useful for financial control, but it answers a different question. It shows spending and receipts during that period, not necessarily the full outcome of the same set of inquiries. Keep the two views distinguishable.
Do not wait indefinitely for a perfect report. Use provisional results with clear labels, then update the relevant outcome when the business has evidence. Honest incompleteness is more useful than a confident but mismatched calculation.
Investigate the point where costs rise
If all-inquiry cost appears reasonable but suitable-request cost is high, inspect service fit and qualification. If suitable requests arrive but few jobs follow, review contact handling, availability, estimate fit and the customer decision.
Those patterns suggest questions rather than automatic conclusions. A lower conversion rate can reflect a different work mix or an incomplete period. Use inquiry reasons and operational context before assigning blame to the channel.
Keep lost reasons specific enough to act on. Outside coverage, unsupported service, unavailable timing and declined estimate point to different corrections. A single poor-lead category prevents the business from learning.
Choose one corrective test and record the measure it should affect. A clearer service page may aim to reduce unsupported inquiries. A response-process repair may aim to increase useful conversations. The test should match the observed loss.
Use a supplier comparison worksheet
For each proposal, record the lead definition, cost basis, service coverage, exclusivity terms where applicable, qualification method, dispute or credit terms and reporting access. Unknown terms should remain questions until the provider answers them.
Compare the complete arrangement rather than a promotional per-lead figure. A lower initial price can be less useful when the requests do not fit, while a broader acquisition system may include assets and work outside a lead purchase. The comparison should state those differences plainly.

Your questions, answered
What is a good price for a plumbing lead?
There is no universal threshold that accounts for your service mix, qualification and job economics. Define the lead, include costs consistently and assess suitable requests and completed work.
Should marketing fees be included in cost per lead?
Include them when the purpose is a broader acquisition-cost comparison, and label the method. A media-only figure is also useful, but it should not be compared directly with an all-inclusive figure.
How do I calculate cost per qualified plumbing lead?
Divide the defined acquisition costs for the period by the number of suitable requests under your agreed criteria. Keep the same time basis and remove duplicate contacts about the same opportunity.
Why is cost per completed job higher than cost per inquiry?
Fewer inquiries usually reach the completed-job stage, so the same spending is divided by a smaller count. Inspect the progression and open opportunities to understand the reason rather than treating the arithmetic as a diagnosis.
Should we stop a channel with a higher lead cost?
First compare service fit, completed work, contribution and the cost method. A higher initial cost can still produce useful work, while a cheap contact can be commercially irrelevant.
