A campaign launched in January. The leads look promising. In March, someone asks whether it worked.
That sounds like a reasonable question until you remember that customers usually take six months to buy. Most of this campaign’s prospects have not had time to make that decision. But “give it more time” is not much of a management plan, either.
The problem is timing. You need to make spending decisions before the final results arrive, without pretending that a meeting booked today is money in the bank.
Give each group of prospects its own clock
I would start by separating prospects according to when they entered the effort. Follow January’s group through qualification, opportunity creation, proposals, losses, and sales. Do the same for February and March.
This is a cohort view. It prevents a familiar mistake: dividing this month’s revenue from older prospects by this month’s spending on new ones. That calculation mixes different buying cycles and can make good work look bad, or bad work look surprisingly productive.
Compare groups at the same age. January prospects at 60 days should be compared with older groups at 60 days, not with a fully matured group that has had nine months to close. Keep the original spend attached to the group even if the budget later changes.
Your advertising dashboard has its own clock. Google explains that a conversion window determines how long after an ad interaction a conversion can be recorded. Check those settings against your actual buying cycle. Your CRM should preserve the longer commercial history rather than treating the platform’s reporting window as the boundary of reality.
Use early evidence without turning it into revenue
Waiting six months does not mean waiting silently. Look for evidence that prospects are taking the next meaningful step. Are the right companies responding? Do meetings happen? Does sales accept the opportunities? Are those opportunities progressing, or sitting untouched?
Define those steps with sales before the campaign begins. A lead that downloaded a document and an opportunity with an agreed next meeting should not receive the same label.
Historical close rates can help estimate what a group might eventually produce. They are assumptions, not earned revenue. If the campaign brings in a different customer segment, or the offer changes, the old rates may be poor guides. Show a range and explain what would move it.
Google’s offline conversion tools can connect later actions, including signed contracts, back to advertising. That helps connect records within the tools’ matching and timing limits. It does not establish that every attributed contract happened because of the ad.
Calculate the economics of the whole effort
Here is a hypothetical example. A campaign costs $18,000 in media and outside services. Staff spend another $6,000 worth of time on production, management, and campaign-specific sales follow-up. The full investment is $24,000.
After the group matures, it produces six contracts worth $20,000 each, or $120,000 in revenue. At a 50% contribution margin after the variable costs of delivery, those contracts provide $60,000 before campaign costs.
Keep cost categories consistent with finance. Campaign-specific sales follow-up is included in the $24,000 here, so it must not also be deducted in the delivery costs used to calculate contribution.
Now the uncomfortable question: how much would have happened anyway? Suppose a credible comparison supports a working estimate of four additional contracts. Incremental revenue is $80,000, and incremental contribution is $40,000. Marketing ROI is ($40,000 minus $24,000) divided by $24,000, or about 67%.
If only two contracts were additional, contribution would be $20,000 and ROI would be about negative 17%. The same six recorded sales can support very different decisions. That is why the assumption about additional business belongs beside the result.
Put an expiration date on patience
A long sales cycle needs decision dates, spending limits, and conditions for continuing. Otherwise, every disappointing month becomes another reason to wait.
At an early review, stop or repair obvious failures such as irrelevant inquiries, broken handoffs, or an offer the target companies will not discuss. At a later review, decide whether qualified opportunities justify another limited round. When the cohort has had a realistic chance to close, judge contribution, full cost, and the remaining uncertainty.
Keep cash timing in the discussion. A potentially profitable program can still be unaffordable if the business must fund six months of work before customers pay. A signed annual contract is also different from collected cash, especially if cancellation or nonpayment is possible.
The useful answer in March might be: “We cannot know final ROI yet. The January group has reached these agreed milestones, we have spent this much, and we will release the next budget only if these conditions hold.”
That is a decision someone can manage. A six-month sale deserves a six-month view, with enough checkpoints to keep patience from becoming an excuse.
