Build a marketing budget around qualified leads, not cheap clicks

A low cost per lead is easy to celebrate because it arrives quickly and fits neatly into a report. Customer acquisition is slower and messier. The budget conversation improves when the team follows the money through qualification and sales instead of stopping at the first submitted form.

This article uses an illustrative service-business example. The numbers are invented to explain the calculation; they are not EBJ results or industry benchmarks.

Work backwards from the business

Imagine a service with CAD 3,000 in revenue per completed project and CAD 1,500 remaining after direct delivery costs. That remaining amount is not automatically available for marketing: overhead, sales effort, refunds and profit still need to be considered. Ask the finance owner what acquisition allowance the business can support.

Suppose the team uses CAD 450 per new customer as a planning assumption. If one in five qualified enquiries becomes a customer, the provisional allowance per qualified enquiry is CAD 90. If half of submitted enquiries qualify, the corresponding allowance per raw enquiry is CAD 45. Each figure depends on the earlier assumptions.

Compare two campaigns fairly

Campaign A generates 100 enquiries at CAD 20 each. Only 20 qualify, and four become customers. Its media acquisition cost is CAD 500 per customer. Campaign B generates 50 enquiries at CAD 30 each. Thirty qualify, and six become customers. Its media acquisition cost is CAD 250 per customer.

Campaign A wins the cheap-lead contest and loses the customer-cost comparison. Neither figure includes creative, agency fees or sales time, so neither should be labelled total acquisition cost. Name the cost basis in every report.

Allow time for outcomes to mature

Do not compare an older campaign with a newer one as if both have had the same selling time. Group enquiries by the period in which they arrived and revisit those groups after an appropriate interval. For long projects, proposals and qualified opportunities can be useful interim signals, provided they are not presented as completed revenue.

Keep duplicate, spam and existing-customer enquiries identifiable. Otherwise the apparent volume can rise without a corresponding increase in new opportunities. A simple CRM status discipline is often more useful than a more elaborate dashboard.

Use ranges where knowledge is weak

For a new channel, calculate a conservative, middle and optimistic scenario. Vary qualification rate and close rate separately. If the plan works only when every assumption is optimistic, the budget is fragile. Set an initial learning allowance that the business can afford without treating uncertain future sales as cash already received.

Include the cost of making the campaign: landing-page work, creative variants, tracking and the capacity to answer enquiries. Ring-fencing all the money for advertising can leave the team unable to fix the journey that advertising depends on.

A practical budget review

Bring four things to the meeting: spend by cost category, enquiry counts with definitions, outcomes by arrival cohort and a list of unresolved assumptions. Ask whether the next dollar should buy more traffic, better creative, a clearer page or faster sales follow-up.

There is no universal correct allocation. A business with strong demand and weak response handling has a different constraint from one with a persuasive offer that few relevant people see. The useful budget is the one that makes that difference explicit and gives the team a controlled way to learn.

Put it to work

Budget through the full funnel and keep assumptions separate from observed outcomes.
