A buyer-side playbook for Microsoft Unified Support: how the percentage-of-product-spend model works, why the bill inflates as you buy more Microsoft, and the scope, spend-base, co-term and third-party levers that bring it back down.
Microsoft Unified Support replaced Premier and changed the question from "how much support do we use" to "how much Microsoft do we buy". The fee is a percentage of your annual Microsoft product spend, so the bill rises with every new licence, every Azure consumption increase, and every Copilot or M365 upgrade, whether or not your team opens a single extra ticket.
This playbook is written for the buyers who sign the Unified Support renewal, not for the account team that quotes it. Every section ends with the buyer move and the discipline that makes the saving stick.
