The Recurring Revenue Hiding in Expiring Warranties

Every aerator, effluent pump and alarm you install starts a manufacturer warranty clock. When that clock runs out, the homeowner is on their own with the next failure. The company that calls first usually gets the work. Here is how to make sure that company is yours.

The Warranty Nobody Is Watching

You installed the part, the customer paid, and the paperwork went in a folder. Somewhere in that folder is the date the manufacturer stops covering it. Nobody looks at that date again until the part fails, and by then the homeowner is shopping for whoever answers the phone.

It slips for the same reasons every time:

  • Warranty terms differ by manufacturer and by part, so there is no single date to remember.
  • The install date is on a job ticket, not on the tank or the part.
  • Nobody owns the follow-up, so it waits until something breaks.

Why the End Date Is a Sales Moment

A warranty ending is one of the few times a homeowner is ready to hear from you. A short call or email sixty days out gives you a reason to offer what they will need anyway:

  • A maintenance contract, so the system is checked on a schedule instead of when it fails.
  • An inspection before coverage ends, while a failed part can still go back to the manufacturer.
  • A planned replacement on your schedule, not an emergency call on a Saturday.

Do the math on your own installs. If you put in 150 aerators and pumps a year and one in five of those customers signs a $300 maintenance contract when the warranty ends, that is $9,000 a year of recurring revenue that renews, plus the repairs that come with it.

A Simple Warranty Routine

  1. Record the warranty length for each part you install. Months, by item, once.
  2. Start the clock on the day the part reaches the customer. Not the day it arrived at your shop.
  3. Keep one list of warranties ending in the next 30, 60 and 90 days.
  4. Make the call at 60 days. Offer the contract, the inspection, or the replacement.
  5. Note the answer. A customer who says not now is still a customer to call when the part fails.

How SepticCycle Tracks Warranties

SepticCycle keeps the dates and the list, so the routine runs without a folder.

  • A warranty length on each inventory item. Set the months once on the item, and every unit of it is tracked from then on.
  • The clock starts at the customer. A serialized part or asset starts its warranty when it first reaches a customer. A part counted by quantity starts on the day its job was completed.
  • Warranties ending soon. One list of every unit with a warranty ending in the next 30, 60 or 90 days, wherever it is now, ready to export.
  • Alert emails to your office. Turn on warranty alerts and every admin and office user gets a daily digest of serialized parts and assets that have just reached 90, 60 or 30 days left.
  • The same answer on every screen. The warranty status of a unit shows on the tank, in its history, and on the job checklist, all worked out the same way.
SepticCycle never contacts your customers about a warranty. The alerts go to your office, and you decide who to call and what to offer.

A warranty call often turns into a maintenance contract. Keep those contracts from lapsing with a renewal process that catches every one.
