Turn a vague conversion problem into a stage-by-stage business estimate.
Pipeline math is useful when it guides a decision, not when it pretends to predict revenue. Model one stage at a time, use conservative assumptions, and compare the value of fixing a handoff with the cost of the work.
What this leak often looks like
- Revenue forecasts assume every lead has equal value.
- The pipeline reports totals without stage conversion rates.
- Old opportunities remain open and inflate expected revenue.
- Marketing and sales use different definitions of a qualified lead.
- Improvement projects are prioritized by opinion rather than estimated impact.
Fix the system in order
Map the stages
Use only stages that represent a real customer commitment: qualified visit, enquiry, qualified opportunity, offer, and purchase.
Add actual counts
For one consistent period, count how many prospects entered and exited each stage. Avoid mixing new leads with a backlog from prior months.
Calculate stage conversion
Divide the number reaching the next stage by the number eligible to advance. The largest percentage drop is not always the largest value opportunity.
Estimate recoverable value
Apply a modest improvement to one stage, multiply the additional expected customers by average gross value, and treat the result as directional.
Test one repair
Change one script, page, qualification rule, or follow-up process. Compare the same cohort definition before and after.
Numbers that help you decide
Stage conversion
Prospects advancing to the next stage divided by prospects eligible to advance.
Pipeline velocity
The time qualified opportunities take to move from entry to a final decision.
Expected gross value
Qualified opportunities multiplied by win rate and average gross customer value.
Stale opportunity rate
Open opportunities with no current next action divided by all open opportunities.
Common mistakes
- Using revenue instead of gross value when comparing acquisition costs.
- Applying an optimistic improvement to every stage at once.
- Leaving stale opportunities in the denominator.
- Treating an illustration as a guarantee.
Straight answers
What numbers do I need for a pipeline leak estimate?+
Use stage counts, conversion rates, average customer value, and a clearly defined time period. Start simple and improve the data later.
Which pipeline stage should I fix first?+
Choose the stage with meaningful recoverable value, enough volume to learn, and a repair the business can control.
Is pipeline value the same as revenue?+
No. It is an estimate based on assumptions about conversion and customer value, so it should guide prioritization rather than financial reporting.
