The Zero-Leakage Funnel Audit. In 90 minutes.

Pull 500 random inquiries from the last 30 days. For each one, compute the delta between lead-created timestamp and first outbound human touch timestamp — not “assigned to rep”, not “opened in CRM”. Actual call placed or message sent.

What you’re looking for

• Median latency — half your leads are worse than this number
• p90 latency — the tail that quietly loses the most revenue
• % of leads with zero touches in 24 hours — the pure leakage number

Industry benchmarks

Draw a 5-column table: Phone · WhatsApp · Email · SMS · Web chat. For each one, answer three questions:

1. What % of outbound attempts use this channel?
2. What’s the connect-rate (someone responded) on this channel?
3. What’s your max attempts policy before you give up?

Most teams discover two things: (a) 85% of their outbound is phone calls — when 62% of buyers prefer WhatsApp or email for first contact; and (b) “give up” happens after 3 attempts over 5 days, when buyers typically take 8–12 touches over 18 days to convert.

Histogram your inquiries by hour-of-day over the last 30 days. Overlay your human team’s actual active hours. The gap between those two curves is your after-hours leakage zone.

What to calculate

• % of inquiries that arrive outside your support/sales working hours
• Conversion rate for those inquiries vs. in-hours ones (usually 30–50% lower)
• Estimated lost revenue = (out-of-hours inquiries) × (in-hours conv rate − out-of-hours conv rate) × (avg deal value)

For most B2C funnels, after-hours inquiries are 28–42% of total volume — and convert at roughly half the rate of in-hours ones. That’s usually the largest single number in the audit.

Pull 50 random “qualified” leads from the last 30 days. For each, answer: did the rep actually capture intent, timeline, budget and channel preference — or did they mark it qualified because someone picked up the phone?

Scoring rubric

• Gold — 4 of 4 fields captured, with specifics (not “yes, interested”)
• Silver — 2–3 fields, usable
• Tin — 0–1 fields, effectively just a “connected” event dressed up

Typical result: 18% gold, 34% silver, 48% tin. Your “48% tin” is why your closers are complaining about lead quality — and they’re right. But the root cause isn’t the lead source; it’s the qualification step.

Shadow one qualified-to-closer hand-off end-to-end. Start at the moment a lead is marked qualified. Stop when the closer places the first substantive call.

Count

• Tools touched (CRM, spreadsheet, WhatsApp, email, phone system…)
• Fields re-entered between systems
• Elapsed wall-clock time
• Context lost (notes, recordings, prior conversation transcripts)

If the hand-off takes more than 90 seconds of rep-time and involves more than 2 tools, you have hand-off friction that’s eroding conversion. Most enterprises we audit come in at 4–7 minutes per hand-off, across 3–5 tools.

You now have five leakage sources quantified. Convert each into dollars using the same formula:

Add the five numbers. That’s your annualized leakage — the money currently on the floor. Most mid-market funnels audit in at 18–35% of pipeline. Enterprise funnels: 12–22%. If you’re running > $10M in pipeline, the dollars get uncomfortable fast.
