Revenue per enquiry as a single measure of the whole funnel

Introduction

Conversion rate and average job value are usually reported separately, and separately they can mislead. A change that raises one while lowering the other looks like an improvement in whichever report gets read first. Raising your prices lowers conversion; loosening qualification raises it. Neither tells you what happened to the money.

Total revenue divided by total enquiries resolves that. It is one number, it moves with anything that genuinely improves the commercial performance of the funnel, and it is impossible to improve by trading one half against the other. For a small business it is probably the single most useful figure available.

It requires only two things you should already be counting.

1. Revenue per enquiry as a single measure is simply a division

The definition.

All revenue won in a period divided by all enquiries received in that period. Nothing else. The simplicity is what makes it survive contact with a busy business. Two cells in a spreadsheet and a third for the result.

2. It exposes the price and volume trade-off

The main reason to use it.

If a price rise lowers conversion but raises this number, the price rise worked. If it does not, it did not. The argument ends there. The same test applies to a discount, in reverse.

3. It punishes low-quality enquiry volume

The useful side effect.

Doubling enquiries with people who cannot afford you halves the figure immediately. Counts alone would call that success. This is the number that makes the difference visible. It also makes qualification look like the improvement it is.

4. Cohort by arrival, not by close

The accuracy adjustment.

Enquiries from March should be matched to the revenue they eventually produced, even if it lands in May. It is more work and it is the honest version. Where cycles are short, the difference is negligible. Where they run to months, cohorting is the only defensible method.

5. Calculate it per source

The decision-making version.

Revenue per enquiry by channel tells you where to spend, in one column. Channels with high volume and low value stand out immediately. Nothing else answers the spending question so directly.

6. Watch it over quarters

The period.

Monthly values bounce with one large job. A quarterly figure is readable and still timely. Keep the series running for years. The trend across eight quarters is where the real answer sits.

7. Use the median for a sense check

The distribution question.

If one contract dominates the period, the mean is describing that contract rather than the funnel. Look at both when a quarter seems unusual. The gap between them is itself informative. A wide gap means your revenue depends on a handful of jobs.

8. Combine it with cost per enquiry

The complete picture.

Revenue per enquiry minus cost per enquiry is close to a margin figure for your acquisition process. Both sides on one line. That is a genuinely complete summary of a small funnel.

9. Set the target here rather than on conversion

The management use.

A conversion rate target invites discounting; a revenue-per-enquiry target does not. It aligns the incentive with the outcome. This alone is a reason to switch which number gets discussed.

Be careful with businesses where a single contract can be twenty times the average. In those cases the figure swings violently and needs a longer period, a median alongside it, or a rule for how large jobs are treated.

Conclusion

Divide total revenue by total enquiries and track the result by quarter.

Use it to settle arguments about price against volume, watch it fall when enquiry quality drops, match enquiries to the revenue they eventually produced rather than to the month it landed, calculate it separately for each source so it can guide spending, check the median when one job dominates, pair it with cost per enquiry for a margin view, and set targets on this figure rather than on conversion rate.
