Where do leads leak between marketing and sales?

Clearmatic · 27 October 2026

The four handoffs where enquiries go missing in a growing B2B business, how to see each one in your own numbers, and what closes the gap.

The short answer

Leads leak at handoffs: from the form to the inbox, from the inbox to a person, from the first reply to the follow-up, and from the CRM to the report that would tell you any of this. Each one is visible if you count what went in and what came out, and that count is the part most teams haven't done.

Key takeaways

  • Leads don't vanish in the middle of a step. They vanish between steps, at the handoffs.
  • There are four handoffs in most businesses, and each can be counted with what you already have.
  • The inbox-to-person handoff is usually the biggest leak and the cheapest to fix.
  • Trace one month of enquiries end to end before you change anything.
  • Closing the gaps is a matter of ownership and timing, and a system can hold both.

Marketing reports that enquiries are up. Sales reports that the pipeline is flat. Both are telling the truth, and the difference between them is somewhere in the handoffs nobody owns. Finding it takes one month of enquiries traced from the form to the report, which almost nobody has done, and no new tool.

The four handoffs

Leads rarely go missing in the middle of a step. A rep who's on a call finishes the call. They go missing between steps, where one system or person hands to another and nobody checks what arrived.

The pipe from marketing to sales, and the four joints where enquiries leak. The second joint, inbox to a person, is usually the biggest.

Form to inbox

The web form sends to an address. The address belongs to someone who left, or forwards to a folder, or is filtered as spam by a rule nobody remembers setting. Campaign replies land in a different inbox from the form. A partner sends referrals by email to one rep. Count the enquiries your form tool recorded last month, then count the ones that reached a place a salesperson looks. The difference is this leak.

Inbox to a person

This is usually the largest leak. An enquiry arrives in a shared inbox that three people can see, and because anyone could answer it, nobody does for two days. Or it's answered, but by the wrong person, who parks it for a colleague. Count the enquiries that reached the inbox, then count the ones that got a first reply within a working day. The gap is here, and it's covered in detail in how fast you should reply to a new lead and routing enquiries to the right person.

Reply to follow-up

The first reply happened. A call happened. A quote went out. Then the week got busy and the second touch never came, so a lead who was deciding slowly decided somewhere else. Count the quotes sent last month, then count the ones that received a follow-up. That gap is the subject of following up every quote without nagging.

CRM to report

The fourth leak is the one that hides the other three. If stages in the CRM are updated by hand, the report you read each month describes what reps remembered to type, and the real count of leads that went quiet is invisible. Count the open deals with no activity in the last two weeks. If that number surprises you, the report has been telling you a story. Keeping the CRM accurate without data entry is how the report starts telling the truth.

One more thing the trace shows: where the enquiries that leaked came from. If most of the ones that never reached a person arrived through one channel, that channel's handoff is the problem, and the fix is narrow. If the slow replies cluster around one rep's absences, the fix is a cover rule. The count tells you which joint, and usually tells you why.

How to count it

Take one month. Export the enquiries from the form tool and every inbox they can arrive in, and give each one a line in a spreadsheet. For each, record four dates: when it arrived, when it was first replied to, when the last touch happened, and what the CRM says about it now. It's an afternoon's work, and it will tell you more than any dashboard, because it follows the actual leads rather than the fields someone filled in.

The four numbers at the end are your leak readings: enquiries that never reached a person, enquiries that waited more than a day, quotes with no follow-up, and deals the CRM calls open that have gone quiet. Keep the spreadsheet. It's the before.

Do the trace once by hand before anything is automated. It takes an afternoon, it needs no tools you don't have, and it's the only way to know which of the four gaps is costing you most. Businesses that skip it tend to fix the leak that's easiest to see rather than the one that's largest.

What closes each gap

Every leak has the same two causes: no clear owner, and nothing holding the timing. So the fixes have the same shape.

  • Form to inbox: every channel captured into one place the moment an enquiry arrives, with nothing depending on a forwarding rule.
  • Inbox to a person: one named owner per enquiry, immediately, with the record gathered and a first reply drafted.
  • Reply to follow-up: a schedule that creates the next touch the moment a quote goes out and prepares each one on time.
  • CRM to report: stages that move because something happened, and a quiet flag on anything untouched for a set period.

Together these are the front of the sales process, which is what we build in Revenue Growth. They can be done one at a time, and the count tells you which one first. If you're unsure, it's almost always the second.

What the count usually shows

Suppose the form tool recorded sixty enquiries last month. Tracing them, you find that fifty-four reached an inbox a salesperson looks at. The other six went to a filtered folder, a forwarding address that stopped working in the spring, and a partner's email to one rep who was away. That's the first leak, and it's fixed in an hour once you know it's there.

Of the fifty-four, thirty-one got a first reply within a working day. The rest waited two, three or in a handful of cases six days, and the pattern is clear when you look at the dates: the slow ones arrived on a Thursday afternoon or in a week when one rep was travelling. That's the second leak, and it's the biggest.

Eighteen quotes went out. Seven had any follow-up at all, and three of those were a single message. Eleven quotes, each representing a conversation that had already happened, were never touched again. That's the third leak.

The CRM says forty deals are open. Twenty-two have had no activity for more than two weeks, and the report sent to the leadership meeting counted all forty as pipeline. That's the fourth leak, and it explains why marketing and sales have been describing different months.

The numbers will be different in your business. The shape usually isn't. And once they're written down, the conversation about whose fault it is turns into a conversation about which joint to fix first.

What to measure

The four leak readings, monthly, on one page: enquiries that reached a person, speed of first response, follow-up completed on every opportunity, and open deals gone quiet. Then the number that marketing and sales can finally agree on: enquiries that progress to a conversation. When that moves, the argument about whose numbers are right ends.

What to do this week

  1. Export last month's enquiries from the form tool and every inbox they can land in.
  2. Give each one four dates: arrived, first reply, last touch, CRM status today.
  3. Count the four leaks.
  4. Pick the biggest one, name an owner for that handoff, and decide what holds the timing.
  5. Put the four counts on one page and agree to look at it monthly.

Questions

Is this a marketing problem or a sales problem?

It's a handoff problem, which is why neither team sees it. Marketing measures what went in and sales measures what came out. The leaks are in between, and the fix is to give each handoff an owner and a system that holds the timing.

Do we need new software to find the leaks?

No. One month of enquiries, four dates each, in a spreadsheet, will show you where they go. New systems come in to close the gaps, and only for the gaps that matter.

Which leak should we fix first?

The count will tell you, and it's usually inbox to a person, because it's the largest and the quickest to fix: one owner per enquiry, immediately, with the record attached. The follow-up gap is often second.

How do we stop the leaks coming back?

Keep the four counts on one page and look at them monthly. A leak that's measured stays closed, because someone notices within a month when it opens again.
