Service Agreements: The Recurring Revenue Most Generator Dealers Leave on the Table
By Andrew Brockenbush · Published · 5 min read
Most generator dealers treat the install like the finish line. The unit goes in, the inspection passes, the check clears, and that homeowner drops out of your world.
Then a year or two later the unit throws a code, or it will not start the morning after a storm. And the homeowner calls whoever shows up first on Google. Maybe that is you. Maybe it is the electrician down the road.
A service agreement is how you stop that from happening. It is a plan the homeowner pays for every year, and in return you come out on a schedule, check the unit, change what needs changing, and put them at the front of the line when things go wrong. It is the closest thing this business has to a paycheck that shows up whether it storms or not.
Why this matters more than one more install
Installs are lumpy. You get slammed after a big outage and then things go quiet. Anyone who has run a generator shop through a calm year knows the feeling.
Service agreements smooth that out. Every plan you sell is money that comes back next year without you buying a single ad. It also keeps your techs busy in the slow months, because maintenance visits can be scheduled whenever you want them.
And there is a bigger reason. The homeowner on a plan is your customer. When they want a second unit for the shop, or a neighbor asks who put theirs in, or their brother-in-law two towns over loses power for three days, your name is the one they already have in their phone.
Sell it at the install, not six months later
The best time to sell a service agreement is the day you hand over the keys. The homeowner just spent real money. They care about protecting it. They trust you right now more than they ever will again.
Six months later they have moved on. Your follow-up email is one of forty in their inbox.
So build it into the quote. Do not make it a surprise add-on at the end. Put it right on the proposal as a line the homeowner can say yes or no to, with a plain explanation of what they get.
- Say what the visit actually includes. Oil, filters, battery check, a test run, a look at the transfer switch (the box that flips your house over to generator power). Real things, not "peace of mind."
- Say how often you come out. Once a year, twice a year, whatever you actually do.
- Say what happens in an outage. If plan customers get called back first, say so. That is the part people buy.
- Tell them to check their manufacturer warranty terms. Some warranties expect regular maintenance. Do not promise anything about coverage you have not read yourself.
Make it easy to say yes
A plan that has to be re-sold every year by phone will leak customers. People forget, the tech who sold it moves on, and nobody calls.
Set it up so it renews on its own. Card on file, one clear renewal date, and a reminder email a few weeks ahead so nobody feels ambushed by the charge. Make canceling simple too. Homeowners stay longer when they do not feel trapped.
Keep the tiers simple. One plan is fine. Two is plenty. If a homeowner needs a phone call to understand the difference between your options, you have too many.
Go back through the customers you already have
Here is the part most dealers skip. Every install you did in the last few years without a plan attached is a service agreement you can still sell.
Pull that list. Sort by install date. Anyone whose unit has been running a couple of years without a visit is a good first call. Send them a short note that says their unit is due for a check, here is what it costs one time, and here is what it costs if they want you to just handle it every year.
Fall is a good time to do this. It is right before winter storms and ice start knocking out power in a lot of the country, and homeowners are thinking about whether that unit will actually start.

Every visit is a marketing moment
A maintenance visit is not just a work order. It is the one time a year you are standing in front of a happy customer. Use it.
Ask for a review when the tech finishes. That homeowner just watched someone show up on time and take care of their stuff. That is exactly when people say yes. More on how to ask: beefygeneratormarketing.com/services/reviews-and-reputation
Take a photo of the unit and the clean pad. Those photos help your Google Business Profile (the listing that shows up on Google Maps) look active and real.
And ask one simple question before leaving: do you know anyone else around here who has been talking about getting one of these? You will be surprised how often the answer is yes.
What this does to your numbers
I am not going to throw a made-up percentage at you. Your numbers depend on your prices, your area, and how many installs you already have out there.
But you can do the math yourself in about two minutes. Take the number of installs you did last year. Imagine some of those homeowners on a plan. Multiply by what you would charge. That is revenue you get next year before the phone rings once. Then think about what it is worth to be the first call when those same people want another unit or send you a neighbor.

Start with the next install
You do not need a new software system or a big launch to start. Add one line to your next proposal. Write down what the visit includes. Put a renewal date on the calendar. Then go work the list of customers you already have.
