What Happens to Warranty and Service Agreement Obligations After a Sale
Why this matters
Every service business has open promises out in the world: workmanship warranties on jobs completed last year, active service agreements with customers who prepaid or are on a recurring contract, and manufacturer warranty pass-throughs you have been the point of contact for. When you sell the business, these obligations do not simply disappear, and failing to address them explicitly in the purchase agreement is one of the most common sources of disputes that surface months after closing, when a customer calls about a warranty repair and both you and the buyer assume it is the other party's problem.
The three categories of obligation to inventory before you sell
- Your own workmanship warranties, the promise that work you performed will be free of installation or workmanship defects for a defined period. This obligation exists because of the work you did, not because of who currently owns the business.
- Active service agreements and maintenance contracts, recurring commitments to a customer, often prepaid in whole or in part, for ongoing service over a defined term.
- Manufacturer warranty pass-throughs, where you registered equipment on a customer's behalf and have served as the point of contact for a manufacturer warranty claim, even though the underlying obligation belongs to the manufacturer, not you.
Get a real list of all three, with rough counts and remaining terms, before you go to market. A buyer's due diligence will ask for exactly this, and having it ready signals a well-run business.
What typically happens in an asset sale
In most small service business sales structured as an asset sale, the purchase agreement explicitly assigns responsibility for these obligations, and it is a negotiated term, not an automatic default. Common structures include:
- The buyer assumes all open warranty and service agreement obligations as part of the purchase, often with the purchase price adjusted to reflect the value or liability of what they are taking on. This is the cleanest outcome for you as the seller, since it fully transfers the future obligation.
- You retain responsibility for warranty work performed before the sale date, while the buyer takes on all agreements and warranties issued after closing. This is common when a buyer is unwilling to underwrite the quality of work they did not perform or oversee.
- A hybrid, time-boxed arrangement, where the buyer assumes the day-to-day handling of existing obligations but you remain financially responsible, through a holdback or indemnification, for claims arising from a defined pre-closing period.
Why a buyer might refuse to simply assume everything
A buyer evaluating your business has no first-hand knowledge of whether a given warranty was issued on quality work or a job you already suspected might need a return visit. Reasonable buyers will ask for a warranty and open-claims history before agreeing to assume everything blindly, and an unusually high number of open or recent warranty claims can itself become a negotiating point that affects price or terms, not just the assignment of responsibility. Disclose this history proactively rather than letting a buyer discover it independently during due diligence.
What to do with prepaid service agreements specifically
Prepaid contracts deserve particular attention because they represent money you have already collected for future work you will not be the one performing. This is typically handled one of two ways in the purchase agreement:
- The value of unearned prepaid revenue is credited to the buyer at closing, since they are the one who will actually deliver the remaining service, and it would be unfair for you to keep money for work someone else now has to perform.
- You retain the prepaid liability and settle it separately, refunding customers directly or working out an alternative arrangement, if the buyer is unwilling to assume those specific contracts.
Whichever structure applies, get it explicitly documented. An ambiguous purchase agreement that is silent on prepaid agreements is a dispute waiting to happen the first time a customer calls asking why the service they already paid for was not delivered.
Communicating this to customers
Once responsibility is assigned, decide with the buyer how and when existing customers with open warranties or agreements are notified of the change in ownership and who to contact going forward. A customer who calls an old number expecting you and instead reaches confusion between buyer and seller about who owes them service is exactly the kind of experience that damages the goodwill you sold as part of the deal.

What to get in writing before you sign
Confirm, in the purchase agreement itself, exactly which obligations transfer, which you retain, how prepaid agreements are valued and credited, and what the indemnification period and process looks like if a dispute over responsibility arises later. A verbal understanding with the buyer about "we'll just handle it as it comes up" is not a substitute for explicit written terms, and it is the single most common gap that turns into a post-closing dispute.
