The free essay gave you the map. This is the instrument.

Most professionals who read the Universal Sales Function framework will recognise themselves somewhere in it. I find the recognition usually comes fast — the framework names something people have felt but never had language for. The harder question is where specifically you’re leaking, and what to do about it. This post works through both.

Step 1: Identify Your Actual Unit

Before you can measure conversion efficiency, you need to know what you’re selling. Not your service category. Your unit.

The unit is the specific commitment you’re asking someone to make. It’s more precise than most people think, and in my experience, misidentifying it is the single most common source of conversion failure.

A fractional GC isn’t selling legal services. The unit is a monthly retained relationship with a defined scope. A fund manager isn’t selling a fund. The unit is a capital commitment from a specific LP profile at a specific ticket size. A founder isn’t selling equity. The unit is a lead investor at a particular valuation who brings the round together.

You can be an excellent communicator and a poor closer if you’re optimising for the wrong thing. Write your unit down. One sentence. If it takes more than that, it isn’t precise enough yet.

Step 2: Map Your Current Conversion Rate

Take the last twelve months. Count the number of genuine sales conversations you initiated or entered — meaning conversations where a commitment was on the table at some point. Then count the ones that closed.

That ratio is your baseline Transmission Efficiency.
