Finding where leads leak: the audit walkthrough

A lead leakage audit is a structured walk along the path a lead travels — capture, acknowledgement, assignment, follow-through, and close-out — measuring the drop-off at each checkpoint with your own data rather than anyone's impressions. Most firms discover their biggest leak is not where they assumed, and that fixing one stage recovers more pipeline than any new marketing spend would buy. The whole exercise takes a few hours with CRM exports, phone logs and inbox timestamps.

Why audit before fixing anything?

Because intuition about leakage is reliably wrong. Owners assume the problem is lead quality or price; the data usually says the problem is response time or abandoned follow-up. Fixing the wrong stage is worse than fixing nothing — it consumes the appetite for change and leaves the actual leak running. The premise underneath The 90-Day Follow-Up Framework applies here in audit form: leads mostly die of neglect, not rejection, and neglect leaves timestamps. You can find it.

There's also a sequencing payoff. Leaks compound multiplicatively — if each of five stages passes 80% of leads, only about a third survive the journey. That same arithmetic means the worst stage dominates the outcome, so an audit that ranks the leaks tells you exactly where one week of fixing buys the most revenue.

What are the five checkpoints?

Walk the lead's journey in order and ask one measurable question at each:

1. Capture — does every enquiry become a record? Compare phone logs, inbox, form submissions and chat transcripts against CRM entries for the same month. The gap is your invisible leak: enquiries that never became data. Missed calls are the usual offender — the missed-enquiry problem in its rawest form.
2. Acknowledgement — how fast does the lead hear anything? Measure enquiry timestamp to first outbound touch. Hours matter here; as an industry rule of thumb, contact rates drop roughly eightfold after the first five minutes. How you capture — chat or forms — matters far less than what this number says about whoever sits behind them.
3. Assignment — does every lead have exactly one named owner? Count records with no owner, or with an owner who has left, changed role, or never knew.
4. Follow-through — how many touches does a non-responding lead actually get? Sample twenty quiet leads and count. Most firms find two touches where deals typically need five or more; this checkpoint is almost always the widest part of the leak.
5. Close-out — what happens at the end? Count deals sitting in limbo: no next action, no closed status, just abandoned mid-pipeline. Each is a lead that was paid for and then lost without a decision.

How do you run the audit mechanically?

The mechanism, start to finish. When you begin, then pick one recent, representative 90-day window — long enough for patterns, recent enough to reflect current practice. When the window is set, then pull four exports: every enquiry by channel, every CRM record created, every logged activity, and every deal with its stage history. When the data is in one spreadsheet, then compute the five checkpoint numbers above. When the numbers exist, then express each as a survival rate — of 100 enquiries, how many were captured, acknowledged inside an hour, assigned, touched five times, closed with a decision. When the survival curve is drawn, then the biggest single drop is your first fix, and nothing else gets attention until it's repaired.

Resist fixing things mid-audit. The discipline of measuring everything first is what stops you spending a month on a leak that turns out to be third on the list.

What do the results typically show?

Patterns recur across service firms. Capture leaks cluster around the phone and out-of-hours enquiries. Acknowledgement times are usually far worse than anyone believed — days, not minutes, once weekends and busy stretches are counted. Follow-through collapses after touch two, not because anyone decided to stop but because nothing forced touch three to happen. And close-out limbo quietly holds a fifth or more of all deals in some firms — hedged, because it varies, but rarely trivial.

Put a number on it before you prioritise: multiply the leaked leads at your worst checkpoint by your average deal value and close rate. That figure — recovered pipeline per month — is what any fix should be judged against, and it's routinely a fraction of what new acquisition costs. It reframes the classic hiring instinct too: before paying £35k+ a year for a BDR to pour more leads into the funnel, it's worth knowing whether the funnel keeps what it's given.

What comes after the audit?

Fix the single worst leak, re-measure a month later, then move to the next. Capture leaks want an acknowledgement layer; assignment leaks want routing to an owner in seconds; follow-through leaks want sequences that run from the CRM; and the leads that leaked over a long buying cycle rather than a short one need a nurture built for nine-month timelines. One leak at a time, measured honestly — the audit is only worth doing if the numbers, not the anecdotes, pick the work.
