What counts as a dormant client?

A client who hired you more than 90 days ago, or past your normal repeat cycle for the type of work, and hasn't come back or been contacted since. In most service businesses, dormant clients are 20 to 40% of the total base, and they're the easiest revenue to recover because they already trust you.

How much revenue can reactivating old clients bring back?

A well-timed reactivation typically recovers 10 to 25% of dormant mandates with no marketing spend. The gain is high because there's no acquisition cost and no trust to build, you're reaching people who already chose you once. The limiting factor is almost never the offer, it's having the list and reaching out at the right time.

What should I say to win back an old client?

Give a reason tied to their situation, not a generic check-in. The sealant you applied is due, their maintenance window is coming, you're working in their area. Relevant and easy to say yes to beats clever or pushy every time. They already trust the work; you're just removing the friction of them having to remember and call you.

How to Reactivate Old Clients (The Cheapest Revenue You Have)

Short answer: your old clients already know you, already trust you, and most of them just forgot to call back. Reactivating them is the cheapest revenue in your business, no ads, no cold calls. To do it you need three things: a list of who's gone quiet, the right moment to reach out, and a reason that's about them, not about you.

1. Know who's actually dormant

A dormant client is someone who hired you more than 90 days ago, or past your normal repeat cycle, and hasn't come back. In most service businesses that's 20 to 40% of your client base, and almost no owner can name them off the top of their head. That's the whole problem: you can't reactivate a list you don't have. The first step isn't a campaign, it's pulling together who they are, when they last bought, and what they bought.

2. Time it to their cycle, not your slow week

The best time to reach a client is when the work is due again, not when you happen to be slow. A driveway sealed two years ago is due now. A maintenance contract ending next month is the moment to call, not after it lapses. When you know what each client bought and when, the outreach lands as useful timing instead of a sales pitch, and useful timing is what gets answered.

3. Give a reason that's about them

"Just checking in" gets ignored. A reason tied to their situation gets a reply: the sealant you applied is due, you're working in their area next week, there's a maintenance window before winter. You don't need to be clever or pushy, you need to be relevant and easy to say yes to. The client already trusts the work, you're just removing the friction of them having to remember and call.

4. Make it happen on its own

A reactivation push you do once, by hand, in a slow week, dies the moment you get busy again, which is exactly when it stops happening. The contractors who actually capture this revenue don't rely on remembering. The system flags each client when they're due and sends or queues the outreach automatically, so dormant clients get reactivated all year, not just the week you had time for it.

The list is sitting there. The system works it.

Reactivation fails for one reason: it depends on the owner remembering, and the owner is busy. Arcset builds the system that keeps the dormant list current, flags each client when they're due, and runs the outreach for you, so the cheapest revenue in your business stops being the one you never get to.
