This case study follows a mid market company that negotiated its Microsoft 365 EA down 19 percent. The client was an 1,800 employee professional services firm in North America, carrying Microsoft 365 as its single largest software line item. Names and identifying details are withheld; this is an anonymised composite built from real buyer side engagement patterns. The numbers below are representative of the outcome, not a specific named account.
Situation: a Microsoft 365 EA on autopilot
The firm ran a three year Microsoft 365 Enterprise Agreement that had renewed once already with little scrutiny. Roughly two thirds of users sat on E5, assigned by default during the previous rollout. The renewal was nine months out, and the incumbent reseller had floated a quote that assumed a flat seat count and a standard annual uplift. Finance saw a large, rising number and little explanation of what drove it.
The overspend found
The assessment built a true usage picture across the tenant and found three clear patterns. First, a large share of E5 seats showed no meaningful use of the premium security, compliance and analytics features that justify the tier; those users needed E3. Second, several hundred seats were inactive: leavers never offboarded and duplicate accounts that had accumulated over two cycles. Third, two standalone add ons duplicated capability already included in the tiers users held. Together these represented a significant slice of the annual Microsoft 365 spend that delivered no value.
Approach: right size first, then negotiate
The work followed the buyer side order. Before any conversation with the vendor, the estate was right sized: E5 seats without premium feature use were marked for downgrade to E3, inactive seats were flagged for reclamation, and the duplicate add ons were slated for removal. This produced a defensible, lower seat and tier baseline grounded in the firm's own data.
With that baseline in hand, the renewal became a negotiation rather than a rubber stamp. The firm engaged early, well ahead of the renewal date, so it was never cornered by the contract window. It brought usage evidence to the table and a credible plan to consolidate rather than expand. The negotiation focused on the seats and tiers actually needed, a fair tier mix of E3 and E5, and a cap on future price increases to protect the next cycle. The timing was aligned to the EA true up so the lower baseline locked in rather than being clawed back. Throughout, the firm kept its own counsel involved for contract interpretation.
Outcome: 19 percent off the Microsoft 365 EA
The combined effect of right sizing and negotiation reduced the Microsoft 365 EA by 19 percent against the incumbent renewal quote. The tier mix shifted so that E5 was held only by users who used it, with the rest on E3. Several hundred inactive seats were reclaimed, and the duplicate add ons were removed. A negotiated price increase cap protected the following cycle, turning a one time saving into a durable lower run rate. Light governance, a joiner and leaver process for seats and a periodic license review, was put in place so the estate would not drift back.
Lessons for buyers
Three lessons carry over to any Microsoft 365 EA renewal. Right size before you negotiate, because the strongest leverage is a defensible lower baseline built from your own usage data. Start early, because runway is the single biggest driver of the outcome and an auto renewal removes it. And cap the increase, because protecting future cycles is often worth as much as the headline discount this year.
The deeper lesson is that Microsoft 365 is rarely a standalone problem. The same patterns, default premium tiers, inactive seats, duplicate capability, run across the whole software estate, which is why this work sits inside a full digital workplace cost optimization engagement rather than a one off vendor review.
How we can do the same for you
This outcome came from two services working together: license right sizing and reclamation to build the lower baseline, and SaaS renewal negotiation to lock it into the contract.
