Five leaks before you get paid, from lead response time to unbilled work

Every enquiry that reaches your business has already cost you something. Maybe a referral you earned, maybe an advert you paid for, maybe years of doing good work. Between that enquiry and the paid invoice there are five places it can leak away, starting with lead response time and ending with work that got done but never got billed.

Each leak is a number you can pull from last month with the inbox, quotes and invoices you already have. This post covers all five, how to measure each one this week, why the first matters most, and what the fix looked like for a solar sales team, a property appraisal firm, a coaching business and my own business.

The five leaks, as five numbers

Leak 1 is about the lead. Leaks 2 and 3 are about closing the deal. Leaks 4 and 5 are about getting paid for work you've already done. They're the same kind of leak underneath: money you'd already earned the right to, slipping out in the gap between one step and the next.

1. 1The reply. Hours from someone's first enquiry to your first reply. Every hour they wait is an hour they can spend asking another firm.
2. 2The follow-up. Quotes or proposals sent last month that got no follow-up inside 48 hours. Each one is a job you priced and then let go cold.
3. 3The yes. Days from sending a quote to having it signed. The work can't start until then, and the client has time to ring your competitors.
4. 4The invoice. Days from finishing a job to sending its invoice. Until that goes out, you've paid to do the work and nobody has paid you.
5. 5Work never billed. Jobs marked done with no invoice against them. Nobody likes looking at this one, because it's work you did for free that nobody noticed.

How to pull each number without new software

You don't need a new tool for any of these. You need last month's inbox, the quotes you sent and your invoices (2:02 in the video). A notepad or a plain sheet with one row per enquiry or job is enough.

1. 1Leak 1, the reply: open your inbox and list every enquiry from last month. Next to each, note when it arrived and when someone first answered it. Use every enquiry, including the ones you were slow on, or the number flatters you.
2. 2Leak 2, the follow-up: take each quote you sent and check whether anyone from your side got back in touch within two days (48 hours). Count the ones where nobody did.
3. 3Leak 3, the yes: put the date each quote went out beside the date it was signed, and count the days in between.
4. 4Leak 4, the invoice: put the date each job finished beside the date its invoice was sent.
5. 5Leak 5, never billed: go through the jobs marked as done and pick out any that have no invoice attached.

If pulling these takes a long time, that is a finding on its own. It means the answers live in too many separate places.

Why lead response time decides the other four

The first leak comes first for a reason. If an enquiry waits too long for an answer, there's no quote to chase, no signature to speed up and no invoice to send.

In my experience, most owners answer enquiries between jobs. That's sensible, because you're on site, on a call or doing the work you're paid for. But it means an enquiry that arrives at 10am might not hear back until that evening, or the day after. While it waits, the person who asked is still shopping, and another firm's site may already be open in the next tab.

That's the old setup. The enquiry sits in an inbox, the reply waits for a gap in your day, and nobody knows how long it took, because nothing recorded it.

Is this only a problem for bigger firms?

Owners often assume this is for companies with a sales team or an ops manager. I've found the opposite. The smaller the team, the more likely it is that the owner is the person answering enquiries between jobs, so the reply leak tends to be bigger in a small business.

What the fix looks like once it's built

New enquiries land in one pipeline, wherever they started: the web form, the inbox, the lead sheets. Each one goes straight to the right person with their name on it, so nobody wonders whose it is. The reply time for every enquiry gets recorded on its own, with nobody keeping a log by hand.

With every enquiry in one place, you can also see which sources send the good ones, and that tells you where to look for the next batch. Most people selling AI start by picking a tool. I start with the number that needs to move and build around what you already use: your inbox, your sheets and your CRM, even if nobody keeps it up to date today.

A solar sales team with four lead sheets

The solar team had leads arriving in 4 separate sheets. The system checks all 4 every 3 minutes and matches each new row against what's already in the pipeline, so no lead goes in twice. All 569 of their leads now sit in one Pipedrive pipeline with zero duplicates, and 7 dashboards run on top of it (5:44 in the video). I wrote up how that lead capture build works in more detail.

A property appraisal firm, from the yes to the invoice

For a property appraisal firm, one move of a deal in the pipeline sends the agreement, takes the deposit, sends the final invoice and delivers the final report. That one step covers both the yes and the invoice leaks. The agreement and invoice chasing write-up shows the full flow.

If your worst numbers are the invoice gap and work never billed, the crane hire billing build is the closest match on the site.

A coaching business that gets reports before each call

The owners of a coaching business get a client-ready report before every check-in call. They told me their clients are happy with the format and that the reports help them on the calls themselves. It isn't one of the five leaks, but it rests on the same idea of having the numbers in one place before anyone needs them. More in the coaching reporting post.

My own funnel

I run my own business on the same kind of system. Contacts, deals, tasks, meeting notes, content and my calendar all live in ABAI OS, one system I built with Claude. By the end of October about 1,300 people had commented on my Instagram post (1,277 in the 29 October snapshot), and 153 had confirmed by email. The biggest leak was easy to spot: 653 people never clicked the button in their DMs. That's the same check I'd run on a business's enquiries.

Three things to settle before anyone builds it

Whoever you hire, these are the questions I'd want answered first, with my own answers.

• What it costs, and whether that can change. A lot of this work is sold by the hour, and the total moves. Every build I do is a fixed fee, guaranteed in writing before any work starts. It covers the system agreed in the blueprint (the plan we settle first), built around your tools, put live on your own account, plus training for your team. Most automations go live within 2 to 4 weeks of agreeing the blueprint.
• What happens when something breaks. It won't run forever untouched, and you shouldn't be left alone with it either. Tools change: a form gets edited, a password gets reset, someone renames a column in a spreadsheet. Alerts go in with the build, so a step that stops doesn't sit there quietly for months.
• Whose accounts it runs on. Yours. If I disappeared tomorrow, everything would still belong to you. From handover there's also a monthly subscription, where I pull your real numbers and report back on the return from the systems in place.

The one number to pull first

If you only measure one thing this week, make it the reply: hours from first enquiry to first reply, across every enquiry last month, not just the quick ones. It's where the leak starts, and the other four depend on it.
