Most OEM maintenance contracts renew on their own. To stop that, you send written notice inside a window, often 30 to 90 days before the end date. Miss it and the contract rolls into another year at the OEM price. Put the notice date in your calendar before you do anything else.
How do you find your notice window?
- Pull the contract, not the quote. The notice clause sits under term, renewal or termination.
- Write down three things per contract: the end date, the notice deadline, and where the notice must go.
- List every contract. Different end dates mean different deadlines.
- No contract on file? Ask the OEM or the reseller for it in writing.
What should the notice say?
Keep it short. Name the contract number, the end date, and that you will not renew. Send it the way the contract requires, and keep proof it arrived. Ours is a one-page template: download the non-renewal letter.
When should you send it?
Early in the window, not on the last day. Line up the replacement before the notice goes out. Our contract starts 30 days before the OEM contract ends, so one month of double coverage absorbs any slip in the handover.
Co-term while you are at it
If every asset ends on a different date, you face this deadline again and again. Align them all to one renewal date. It costs nothing and it is the biggest operational win in a switch. The full 90-day plan is on How to switch from OEM support.
