The cheapest revenue in your business is already in the book

A pool builder's winter. A mechanical contractor's January. An eCommerce brand's third quarter. The owner's plan for the quiet months is almost always to buy more leads, because leads are the thing you can point at and feel like you are doing something.

Meanwhile there are hundreds of people in your records who have already decided you are worth paying, and nobody has spoken to them in two years. That is the cheapest revenue in your business and it is being left on the table.

Three offers worth making

• Service and maintenance. The thing that has to happen anyway, sold on a schedule instead of waiting for a breakdown. This is what carries pool builders and air conditioning businesses through the off months.
• Renovation and replacement. Sorted by job age, not by whoever rings. A system installed six years ago is a conversation to have now, not when it fails in front of a customer.
• Win-backs. Every job that went quiet gets one call at ninety days and one at a year. Most owners have never counted how many of those there are, and it is rarely a small number.

An existing customer does not need convincing you exist, that you do good work, or that you turn up. You have already bought that trust, and it is sitting there depreciating.

Why owners skip it

Because it feels like admin. It has no launch date, nobody cuts a ribbon, and it does not look like growth on a whiteboard. Also, nobody owns it. The owner thinks the office does it, the office thinks the owner does it, and both are right that it is not happening.

There is a second reason. It is easier to blame the market than to phone forty customers and find out whether they would buy something. A lead problem is somebody else's fault. An untapped customer base is yours.

How to start on Monday

• Pull every job from the last three years and sort by date.
• Write down the one offer that makes sense for a job of that age, in one sentence, with a price or a price range next to it.
• Phone twenty of the oldest. Not an email — a call, with a specific thing being offered and a date attached.
• Keep a column for the reason each one said no. That column will tell you what the real offer should be.

You will find out within a week whether the quiet season is a demand problem or a nobody-asked problem. The two feel identical from the office and are completely different in the bank account.

Before you spend anything on strangers, spend a fortnight on the people who have already paid you.
