In short
- Sales leakage is usually systemic, not individual: it comes from gaps in ownership, definitions, handoffs and review routines.
- Walk the process stage by stage and ask at each point: what can fall through here, how would we know, and who is responsible?
- Look at the evidence — ageing leads, stalled opportunities, unexplained losses — rather than relying on opinions about where deals are lost.
- Fix the earliest, highest-volume leak first. Improvements further down the funnel are wasted if leads never reach them.
What sales process leakage means
Leakage is revenue the business had a reasonable chance of winning but did not, because of how the sales process operates rather than because a competitor was better or the customer did not need the product. It includes leads that were never followed up, qualified prospects handed over without context, opportunities that stalled without anyone noticing, and deals lost for reasons nobody recorded.
Most sales teams have a view on where they lose business. It is often wrong, or at least incomplete, because each person sees only part of the process. A stage-by-stage review replaces opinion with evidence.
How to run the review
Take a recent period — a quarter is usually enough — and trace what happened to leads and opportunities at each stage. Use CRM data where it exists, spreadsheets where it does not, and short conversations with salespeople and managers to understand the reasons behind the numbers. For each stage, look for three things: volume lost, time lost and information lost.
1. Lead capture
Where it leaks: enquiries arrive through the website, phone, email, WhatsApp, events, partners and walk-ins — and some never get recorded. Leads that are not recorded cannot be followed up, measured or attributed.
How to check: compare enquiry volumes in each channel with the number of leads in your CRM or tracker for the same period. Ask front-line staff how they handle enquiries that arrive outside normal channels.
What fixes it: one entry point for all leads, with each channel feeding it — automatically where possible.
2. Qualification
Where it leaks: without agreed qualification rules, salespeople either chase every lead, wasting time on poor fits, or discard leads too early based on instinct. Both lose revenue.
How to check: review a sample of disqualified leads. Would a different salesperson have pursued them? Review a sample of lost opportunities. Should they have been qualified out earlier?
What fixes it: a short, written set of qualification criteria that everyone applies, and a clear route for leads that are not ready to buy yet.
3. Ownership
Where it leaks: leads and accounts without a clear owner are nobody's priority. This is common for leads from shared channels, for accounts whose salesperson has left, and for territories under review.
How to check: count leads and opportunities without an owner, or owned by people who have left or changed role. Check how long new leads wait before assignment.
What fixes it: clear assignment rules, a time limit for assignment, and a routine for reassigning records when people move.
4. Handoffs
Where it leaks: every handoff — marketing to sales, inside sales to field sales, sales to pre-sales, sales to delivery or customer service — is a point where context can be lost and responsiveness can drop. Customers notice when they have to repeat themselves.
How to check: trace a sample of deals across each handoff. How long did the transfer take? What information was passed on? Was the customer contacted promptly by the receiving team?
What fixes it: a defined handoff: what information must accompany it, the response time expected, and confirmation that the receiving person has accepted it.
5. Opportunity stages
Where it leaks: when stages are loosely defined, opportunities sit in the wrong stage. The pipeline looks healthier than it is, management focuses on the wrong deals, and forecasts inflate.
How to check: pick a sample of opportunities in each stage and ask the owner to describe the deal. Does the description match what the stage is meant to mean?
What fixes it: a small number of stages, each defined from the buyer's point of view.
6. Stage definitions and exit criteria
Where it leaks: without exit criteria, deals advance because a salesperson feels positive, not because something has changed on the customer's side. The same deal can be "proposal" for one person and "negotiation" for another.
How to check: ask three salespeople what must be true for a deal to move from one stage to the next. Compare the answers.
What fixes it: written exit criteria for each stage. The CRM requirements checklist includes an example of stage definitions and exit criteria you can adapt.
7. Follow-up
Where it leaks: this is often the largest leak of all. Proposals are sent and not followed up; a customer asks for time and is never contacted again; a demo happens and the next step is not agreed.
How to check: look at open opportunities with no activity in the last few weeks, and at opportunities without a scheduled next step.
What fixes it: a rule that every open opportunity has a dated next step, and a manager routine that reviews those without one.
8. Stalled opportunities
Where it leaks: deals that have stopped moving but are never closed out. They clutter the pipeline, distort forecasts and absorb attention that should go to live deals.
How to check: list opportunities that have been in the same stage much longer than a typical deal, and those whose close date has been pushed back repeatedly.
What fixes it: an agreed maximum time in each stage for your sales cycle, after which a deal must be reviewed, re-qualified or closed as lost.
9. Pipeline review
Where it leaks: pipeline reviews that become status updates — each salesperson reads out their deals — do not change outcomes. Problems are heard but not acted on.
How to check: sit in on a pipeline review. Were decisions made? Were next actions agreed with owners and dates? Were stalled deals challenged?
What fixes it: a review structure that focuses on exceptions — deals that moved, deals that stalled, deals at risk — and ends with specific actions.
10. Manager interventions
Where it leaks: managers intervene too late — when a deal is already lost — or intervene in the deals they find interesting rather than the ones where help would make a difference.
How to check: review a sample of large or strategic deals from the last period. When did a manager first become involved? What difference did it make?
What fixes it: agreed triggers for manager involvement — deal size, stage, time stalled, competitive threat — so that intervention is systematic rather than ad hoc.
11. Reporting
Where it leaks: reports that show totals but not movement hide leakage. Knowing the pipeline value is less useful than knowing what entered, what advanced, what stalled and what was lost this period.
How to check: can you answer, from existing reports, how many leads were received last month, how many were contacted within the expected time, and how many became opportunities?
What fixes it: a small set of flow reports — conversion between stages, time in stage, loss reasons — alongside the pipeline snapshot.
12. Forecasting
Where it leaks: an unreliable forecast is often the first visible symptom of process leakage upstream. If stage definitions are loose and stalled deals are not cleared, the forecast will overstate what will close. The guide to improving sales forecast accuracy covers the stage rules and review cadence in detail.
13. Conversion leakage
Bring the stage-by-stage findings together in a simple leakage map: for each stage, the volume that entered, the volume that progressed, the typical time spent, and the main reasons for loss. Compare across teams, products or regions. Large differences between teams selling similar products to similar customers usually point to a process or management difference rather than a market one.
| Stage | Entered | Progressed | Typical time in stage | Main reasons lost or stalled | Owner of the fix |
|---|---|---|---|---|---|
| Lead captured | |||||
| Qualified | |||||
| Opportunity stages | |||||
| Won / lost |

14. What to fix first
Resist the urge to fix every leak at once. Prioritise using three questions:
- Where is the largest volume lost? A leak early in the funnel affects everything after it.
- Which fix is simplest to implement? Ownership rules and next-step discipline often cost little and change a lot.
- Which fix will managers actually enforce? A process change without a management routine behind it fades within weeks.
The objective is not a perfect process on paper. It is a process your team actually follows, with managers who can see when it is not followed.

SALES & CRM HEALTH CHECK
Find where your sales process leaks
Review where your current sales process is creating leakage or inconsistency. The Sales Process Optimisation focus of the Sales & CRM Health Check examines lead capture, qualification, handoffs, stages, ownership, follow-up and pipeline reviews.
This perspective draws on operating experience across CRM transformation, sales planning, management reporting and commercial systems. It is practical management guidance, not a vendor recommendation.
