How many businesses are actually in your radius?

There is a question nobody selling prospecting software wants you to ask before you pay: how many businesses of the kind I sell to are actually within driving distance of me? Not how many leads the tool can generate. How many exist.

For some readers the answer is several thousand and the question is academic. For others it is eighty, and no software on earth changes that.

A territory is a stock, not a stream

Lead tools are priced and marketed as though leads were a stream — a tap you open every month, at a fixed rate, forever. Inside a fixed radius they are nothing of the sort. They are a stock: a finite set of real businesses that exist whether or not you are looking at them, and which you draw down as you work through it.

This is the part that catches people out in month three. You hunt, you find two hundred and forty commercial offices inside twenty miles, you work through the good ones, and then you hunt again and the software returns the same two hundred and forty offices, because that is how many there are. Nothing has broken. You have simply finished.

A stream can be rented monthly. A stock is bought once and then either grows on its own or does not. Whether your territory is one or the other is the single biggest thing determining whether a subscription like ours is worth your money, and it is knowable in advance.

The arithmetic

Three multiplications, and no software required to do them.

First, the area you have chosen: a radius of r miles is πr² square miles. This is the step that surprises people, because area grows with the square. Doubling a radius from ten miles to twenty does not double your territory, it quadruples it — and it quadruples the driving too, which is a separate cost we have written about.

Second, the people: multiply that area by how densely your part of the world is populated. Rural counties run well under a hundred people per square mile. Suburban rings run one to three thousand. City cores run past ten.

Third, the businesses: for any given category, the number of establishments per hundred thousand people is remarkably stable across the country. There are roughly fifty-five dental offices per hundred thousand people almost everywhere, because dentistry serves people and people are distributed. Restaurants run near two hundred. Veterinary clinics near ten.

Multiply the three and you have an estimate of how many businesses of your type sit inside the circle you drew. Divide by how many you can genuinely approach in a week, and you have the only number that matters: how many months of work your territory contains.

Size your own

If it comes back thin

Three honest options, in the order most people should consider them.

Widen the radius. The cheapest move on paper and the most expensive in practice, because the area grows with the square while your working day does not. Before you widen, run the drive-cost calculator on the new number. A territory you cannot service profitably is not a bigger territory.

Add adjacent categories. Usually the better answer. A commercial cleaner who counts only dental clinics has undercounted their own market by an order of magnitude — medical offices, law firms, accountants and daycares are all the same sale with a different sign on the door. Most sellers define their niche more narrowly than their capability.

Accept that it is a project, not a subscription. If you have ninety possible customers within an hour's drive, the honest answer is that you do not need prospecting software every month. You need one good list, once, and then a way to follow up for the next two years. Say so and we will tell you the same.

Where the floor is

We put it at about two hundred businesses. Below that, a monthly subscription to a prospecting tool is difficult to justify: at ten approaches a week you will have worked the entire territory inside five months, and the tool has nothing further to give you.

Between two hundred and about four hundred, it works — but plan for the day you finish, and choose the tool that helps you follow up rather than the one that helps you find.

Above four hundred, the territory is deep enough that finding is a genuine ongoing job and the arithmetic stops arguing with you.

Why we published this

Because we sell a $79 a month subscription, and a calculator that only ever said yes, plenty, sign up would be a sales pitch wearing a calculator's clothes. The numbers above will tell some readers not to buy from us. That is the point, and it is cheaper for both of us to find out now than in month three.

It is also the same principle the product itself runs on. ZipQuarry will not invent an email address it cannot source, and it will not send anything you have not read. A tool that tells you comfortable things is not a tool, it is advertising with an input field.
