Where Your Sales Funnel Is Actually Leaking
Leads come in and revenue does not follow, but nobody can say exactly where the gap is. Here are the five places a B2B sales funnel most commonly loses people, and how to find which one is yours using numbers you probably already have.
Why does my funnel have leads at the top but no revenue at the bottom?
Because volume at the top of a funnel tells you almost nothing about what happens after, and most teams only track the two endpoints, leads in and deals closed, without measuring the stages between them. A healthy top of funnel with a dead bottom means the leak is somewhere in the middle, and you cannot fix a leak you have not located. Before changing your offer, your pricing, or your lead sources, find the specific stage where prospects actually stop moving forward.
Is the leak in lead quality or in the process?
Separate these before doing anything else, because the fixes are completely different. A lead quality problem looks like this: leads respond to nothing, ghost after one email, or take a call and are clearly not a fit within the first two minutes. A process problem looks different: leads engage, seem genuinely interested, and then stall or disappear at a specific later stage, like after a proposal goes out or after the first call. If your leads are engaging early and dying later, the problem is downstream in your process, not in who you are targeting, and no amount of better targeting will fix a broken proposal or follow-up process.
Is the funnel leaking at first response?
Check your speed to lead first, because it is the single most common leak and the easiest to measure. If a lead fills out a form or replies to an email and does not hear back for a day or more, a meaningful share of them have already moved on or lost interest by the time you respond. Pull the actual timestamps for your last twenty leads: request in, first response out. If that gap regularly exceeds a few hours during business time, you have found a leak that costs you leads before a human on your team even has a real conversation with them.
Is it leaking between first contact and a qualified call?
This is usually a targeting or messaging leak rather than a speed leak. If leads respond quickly but a large share turn out to be a poor fit, wrong company size, wrong budget, wrong authority to buy, the leak is upstream of your sales process entirely, in whoever or whatever is generating the leads in the first place. Pull your last fifty leads and tag each one fit or not fit based on your actual ICP criteria. If more than half are not a fit, no amount of sales skill downstream fixes that; the fix is in targeting, not in follow-up.
Is it leaking after the proposal goes out?
This is one of the most common and most fixable leaks in a B2B funnel. Deals that go quiet after a proposal usually mean one of three things: the proposal went to someone without the authority to approve it, the pricing does not match what was discussed as acceptable during the sales conversation, or nobody has a defined next step after sending it. Check your last ten proposals: did you confirm the recipient could actually sign off, did you agree on a follow-up date before sending it, and did you hear back within that window. If proposals routinely go out with no scheduled next touch, that silence is not the prospect losing interest, it is a process gap you created.
Is it leaking in the handoff between marketing and sales?
Common on teams where lead generation and sales sit in different functions, or where a founder generates leads and someone else closes them. A lead that comes in "warm" from marketing or outreach can go cold fast if the handoff loses context, meaning the sales rep does not know why the lead engaged, what they were told, or what they are expecting when they get on a call. If your close rate on handed-off leads is noticeably worse than on leads the closer generated personally, look at what information gets lost between the two, not at the closer's skill. A shared CRM with notes at every stage change closes most of this gap on its own.
How do you find your specific leak with the data you have?
Build a simple stage-by-stage count for your last quarter: leads in, responded, qualified call held, proposal sent, closed. Calculate the percentage drop between each consecutive stage. The stage with the steepest drop relative to what you would reasonably expect is your leak, and it is almost always more useful to fix that one stage thoroughly than to make small improvements everywhere at once. If you do not have clean enough data to run this exercise, that itself is worth fixing before anything else, since you cannot diagnose a funnel you cannot see. A lead generation audit does exactly this stage-by-stage breakdown when you want an outside, objective look at where your specific funnel is losing people.
What should you fix first once you find the leak?
Fix the earliest leak in the funnel before the later ones, because a leak early in the process suppresses every stage after it. If speed to lead is broken, fixing your proposal follow-up will not matter much, because fewer leads are reaching the proposal stage healthy in the first place. Work from the top down, confirm each fix actually moved the number for that stage before moving to the next one, and resist the urge to fix everything simultaneously, since you will not know which change actually worked. If the leak turns out to be upstream of your process entirely, in who is entering the funnel to begin with, tightening your ideal customer profile is usually the highest-leverage fix available.

FAQ
How do I find where my sales funnel is losing prospects?+
Build a stage-by-stage count of leads in, responded, qualified call held, proposal sent, and closed for a recent period, then calculate the percentage drop between each stage. The stage with the steepest unexpected drop is your leak, and it is more useful to fix that one stage thoroughly than to tweak everything at once.
Is a low close rate a lead quality problem or a process problem?+
If leads barely respond or clearly are not a fit within the first conversation, that is a lead quality problem, upstream of your sales process. If leads engage well early and then stall or disappear at a specific later stage, the leak is in your process, such as follow-up or proposal handling, not in targeting.
Does speed to lead really affect conversion rate that much?+
Yes. A meaningful share of leads lose interest or move on if first response takes more than a few hours during business time. Pulling the actual timestamps for your last twenty leads is the fastest way to check whether this is your funnel's leak.
Why do deals go quiet after I send a proposal?+
Usually one of three reasons: the proposal went to someone without authority to approve it, the pricing did not match what was discussed earlier in the sales conversation, or there was no scheduled follow-up date after sending it. All three are process gaps you can fix without changing your offer.
