Almost every business that takes inbound inquiries measures two things.
How many came in. How many turned into work.
Both are easy to get, both go in the monthly numbers, and together they tell you a conversion rate that moves around for reasons nobody can explain. When it drops, the conversation is about lead quality or the market or the season, because those are the only explanations the two numbers can support.
The explanation is usually somewhere in the middle, and the middle is not measured.
The four in between
None of these require software you do not have. All four can be pulled by hand for a single month, which is the right way to start.
1. Time to first response, by channel
Not your average across everything. By channel, and including the ones that arrive when you are closed.
The reason to split by channel is that they behave completely differently. A phone call is answered in seconds or not at all. A web form waits for someone to look. A referral text lands on a personal phone and gets a reply in four minutes or four days depending entirely on who received it.
An average across all of that describes nothing real. Split it, and one channel is usually much worse than the others, which makes the problem specific instead of general.
2. Share arriving outside working hours
Count them. Do not estimate, and do not use a number from an article — including this one. The share varies enormously by trade and by business, and the figures that circulate are mostly unsourced.
You need your own number because it determines whether out-of-hours coverage is worth anything to you. If it is 8%, this is not your problem. If it is 35%, it is most of your problem. The reason this one is worth counting rather than assuming is covered in the Friday evening inquiry — the out-of-hours share is usually smaller than people expect, and that is exactly what makes those inquiries expensive.
3. Inquiries with no named owner
For each inquiry last month: was there a specific person responsible for responding to it?
Not "the office" or "whoever picked it up" — a name that could have been written down at the moment it arrived. Count how many have one and how many do not.
This is the measurement people find most uncomfortable, because it is usually the highest number, and because it cannot be blamed on anything external. It is also the one that predicts the others. An inquiry without an owner is the one that gets a slow response, and the one nobody chased.
4. Missed calls without a callback
Pull last month's inbound calls. Filter to ones outside opening hours, or ones under fifteen seconds. For each, check whether a call went back out to that number within the next working day.
Most operations have never run this. It is the only one of the four that requires looking somewhere other than the inbox, and it is usually the one that produces the largest surprise, because a missed call with no callback leaves no other trace anywhere in the business. The calls you never knew about walks through this one in detail, including how to separate a service call from a new customer who found you and gave up.
What the four together tell you
Individually these are just numbers. Together they describe a shape.
If response times are fine in-hours and terrible out of hours, and the out-of-hours share is small, you have a tail problem — a handful of inquiries that get lost and never appear in the average. Worth fixing cheaply, not worth restructuring around.
If a large share of inquiries have no named owner, response time is a symptom and ownership is the disease. Adding an answering service will not fix it, because the problem is not that nobody answered — it is that nobody was responsible after they did.
If the missed-call number is high, you have a channel that is not being managed at all, and everything you have been measuring has been about a different channel.
And if all four look good, then the conversion rate really is about lead quality, and you now know that rather than assuming it. That is a genuinely useful outcome and it happens more often than the people selling intake systems would like to admit.
How often to do it
Once, properly, by hand — then quarterly, and only the two that moved.
The temptation after a first pass is to build a dashboard. Resist it for at least two cycles. A dashboard built before you understand which numbers matter tends to track the ones that were easiest to wire up, and those become the numbers the business manages by, regardless of whether they explain anything.
The measurement that is not on the list
You will notice none of these is "how fast do we usually respond."
That is deliberate. Asked as a general question, everyone answers with their best day during working hours, honestly and inaccurately. The four above are countable from records that already exist, which means they cannot be answered from memory — and memory is exactly what is wrong with the way most operations understand their own intake.
One month of these four, pulled by hand, will tell you more about why the number moved than a year of the two you already collect.
