The Weekly Leak

Every business leaks revenue. These are the 12 places.

One concrete leak, its cost in numbers, and the exact fix. This is the archive behind the Weekly Leak email: the 12 canonical revenue leaks we measure across the four systems of the closed loop. Every number cited, no exceptions.

Voice

The missed-call leak

SMBs miss ~62% of inbound calls, and ~85% of missed callers never call back.

Every unanswered ring is a buyer who dials the next result on Google. The revenue does not postpone, it defects.

The fix: Measure your number with the Open Loop Tax Calculator, then close the gap with 24/7 pickup.

Voice

The after-hours dead-air leak

~28% of bookable demand arrives outside business hours; most firms cover 50 of 168 weekly hours.

The phone is a storefront that closes at five while a third of the buyers shop at nine.

The fix: An AI receptionist answers hour 51 through 168. Hear a live one in the Voice Agent Sandbox.

Voice

The 47-hour response leak

Responding to a lead within 5 minutes converts ~4x better than within an hour. The industry median response is 47 hours.

Speed is the highest-leverage sales variable that costs nothing but a system.

The fix: Wire an automatic first-touch: instant callback, instant SMS, calendar link. Ops automation does this.

Site

The one-second leak

Every extra second of page load costs ~7% of conversions; 53% of mobile visits bounce past 3 seconds.

You paid to get the visitor. The spinner sends them back to the results page for free.

The fix: A sub-second site is a build choice, not a hosting upgrade. Our builds ship Lighthouse 95+.

Site

The form-friction leak

Every form field beyond three drops completion by 15-25%. The average contact form has 6-9 fields.

Each extra field is a small tax on intent. Enough small taxes and the buyer abandons the cart of talking to you.

The fix: Ask for name, contact, and one qualifying question. Get the rest on the call.

Site

The missing-proof leak

Sites without visible proof convert at 0.5-1.5%; with strong proof, 2-4%. Roughly a 2x difference at zero infrastructure cost.

Buyers do not believe claims, they believe receipts: named clients, numbers, screenshots.

The fix: Put one real number and one real name on every money page. Our case studies show the format.

Creative

The single-channel leak

Firms in the €1M-€50M range average 4.2 active acquisition channels. One- and two-channel operations leak 18-35% of their reachable market.

One channel means one algorithm change between you and a bad quarter.

The fix: Map which of the four systems (creative, site, voice, ops) refills your top of funnel, then add the second channel deliberately.

Creative

The stale-creative leak

Bottom-quartile advertisers test fewer than 5 ad variants a quarter; the top quartile runs 20+.

Winning ads decay. Without a testing cadence you keep paying yesterday’s CPM for yesterday’s winner.

The fix: A variant cadence is an ops problem, not a genius problem. The Ad Factory runs it on a schedule.

Creative

The bounced-visitor leak

~67% of visitors who bounce are never re-engaged, while warm retargeting reaches them at a fraction of cold CPM.

You already paid the expensive part: attention. Letting it expire un-retargeted is buying the lead twice.

The fix: A basic two-step retargeting audience recovers visitors your ads already paid for.

Ops

The failed-payment leak

Payment failures cause ~40% of all B2B subscription churn, and most of it is recoverable with a dunning sequence.

The customer did not decide to leave. The card expired, nobody followed up, and the system called it churn.

The fix: A three-step dunning flow (retry, reminder, updated-card link) is an afternoon of ops automation.

Ops

The unplayed-renewal leak

A 5% improvement in retention lifts profit 25-95%, yet roughly a third of renewals get no active play at all.

New-logo revenue gets a pipeline and a party. Renewal revenue gets an invoice and a prayer.

The fix: A renewal calendar with a 60-day-out touchpoint is the cheapest revenue program you will ever run.

Ops

The missing-upsell leak

Existing customers buy 50-67% more readily than new prospects, yet most SMBs run no upsell motion at all.

The easiest sale in your business is sitting in your own customer table, unasked.

The fix: One quarterly value-review email per active client. Systemize it and the leak closes itself.

What is the Weekly Leak?+

A receipts-only series about revenue leaks in small and mid-size businesses: one concrete leak per issue, its measured cost, and the fix. This page is the permanent archive; the email edition delivers one leak a week.

Where do the numbers come from?+

Every statistic is cited to a primary source or to the Revenue Leak Heatmap methodology, which itself cites industry research. If a number has no source, it does not get published.

How do I know which leak is costing me most?+

Run the free Revenue Leak Heatmap. It takes about 5 minutes, maps your business across all 12 cells, and ranks your top 3 leaks by recoverable revenue against peer benchmarks.

Is this just marketing for Kratt services?+

The fixes are real regardless of who implements them, and most can be built in-house. Where a fix maps to something we build, we link it. Where it does not, we say what to do anyway.

How often does the archive update?+

The 12 canonical leaks are stable; their statistics get refreshed when sources update. New leak patterns from real client work are added as they earn a place with evidence.
