Your best lead source is the job you finished well.
Many small businesses finish a job, send the invoice and move on. The customer is left with the result but no record of what was done, how it works, or who to ask. Months later, when a friend asks for a recommendation, the customer remembers the result vaguely and the name not at all.
A one-page handoff is a small habit with a long tail. It tells the customer what you did, shows them how to repeat or maintain it, and says who on their side owns it now. People who can rerun your work tend to trust it, and people who trust it tend to mention it.
It also makes your own next visit shorter, because the facts are written down.
What to do
- At the end of each job, write one page. Keep it plain and short.
- Say what was done, in the customer's words, not yours.
- Say how to rerun or maintain it: the steps, the tools, how often.
- Say who on their side owns it now, and what to do if something looks wrong.
- Add a short note on what they can repeat without you, and what would need a call.
- Send it with the invoice, and keep a copy where you can find it.
When not to
Do not turn the handoff into a sales page or an advertisement. It is useful only if it is honest and plain. And if a job was rushed or did not go well, fix that first. A tidy page about poor work will not help you.
