Mechanics, timing, six common traps, Copilot True Up rules, and the buyer side checklist that contains True Up inflation under 3 percent.
The Microsoft EA True Up is the annual reconciliation that adds incremental consumption to the EA baseline. The mechanic is one direction. The True Up only goes up inside the term. The buyer side discipline determines whether the True Up tracks consumption or inflates beyond it.
The 2026 guide below incorporates Copilot True Up rules, MCA E transitions, and the latest LSP reporting changes. Read the related Microsoft practice, the EA renewal guide, the M365 reclamation guide, the CIO proposal playbook, and the Microsoft knowledge hub.
The True Up mechanic is the annual reconciliation of consumed against committed licenses. The customer reports the incremental quantity above the EA baseline. Microsoft invoices at the held EA price. The new total becomes the EA baseline for the remainder of the term.
| Product family | True Up cadence | Reporting unit |
|---|---|---|
| Microsoft 365 (E3, E5, F1, F3) | Annual | Active assigned users |
| Microsoft 365 Copilot | Annual | Active assigned Copilot users |
| Office 365 (legacy) | Annual | Active assigned users |
| Defender add ons | Annual | Active assigned users |
| Power BI Pro and Premium per user | Annual | Active assigned users |
| Windows Server, SQL Server | Annual | Cores and devices |
The True Up price is the held EA price prorated for the remainder of the term. A True Up filed at month 24 of a 36 month EA is invoiced at one year of pricing rather than three years. The proration mechanic is standard EA paper.
The True Up reporting window opens 60 days before the EA anniversary and closes 30 days after. The buyer side workstream should run 90 days ahead of the window opening.
Programs that start the True Up work when the window opens rarely catch the inflation patterns. The 90 day pre window is the discipline that converts a vendor led True Up into a buyer side reconciliation. Microsoft account teams typically welcome this discipline because it produces cleaner final numbers.
Six traps dominate the True Up inflation pattern. Each trap maps to a buyer side check that the discipline closes.
| Trap | Typical inflation | Buyer side check |
|---|---|---|
| Copilot overrun | 20 to 60% of Copilot base | Adoption telemetry, not M365 base |
| M&A seat sweep | 5 to 15% of new entity | Acquired company seat reconciliation |
| Service account inflation | 2 to 6% | Service account inventory |
| Plan step up (E3 to E5) | 0 to 8% | Validate against role mapping |
| Add on creep (Defender, P2) | 3 to 9% | Telemetry per add on |
| LSP default reporting | 4 to 12% | Independent validation |
Microsoft 365 Copilot follows the standard EA True Up mechanic with one critical difference. Copilot adoption inside the first 12 months runs well below the assigned count. The True Up should reflect active use, not seat assignment.
The buyer side Copilot True Up counter follows three steps. Pull adoption telemetry. Cross reference with assigned seats. Right size the True Up to active use plus a documented growth buffer.
Enterprises that ran Copilot pilots in 2024 typically observe 25 to 45 percent active use of assigned Copilot inside the first 12 months. The True Up should sit close to this active count, not at 100 percent of M365 base. The difference is the largest single True Up containment lever.
The buyer side validation process compares the LSP True Up draft against the internal baseline. The process runs as a four step reconciliation.
The dispute window is the 30 day period after anniversary in which the customer can challenge the True Up invoice. Disputes resolve faster when filed inside the first 14 days.
The eight step checklist below moves a Microsoft EA True Up from drift to disciplined reconciliation across the 150 day window.
A Microsoft EA True Up is the annual reconciliation between consumed and committed licenses. The customer reports incremental consumption above the EA baseline at the anniversary date. Microsoft invoices the incremental quantity at the held EA price, prorated for the remaining term. The True Up cannot go down inside the EA term.
The True Up is run annually on the EA anniversary date. The reporting window opens 60 days before the anniversary and closes 30 days after. The buyer side should run the consumption reconciliation 90 days ahead of the window opening, which gives time to validate, dispute, and right size the True Up report before submission.
Six traps dominate. Copilot True Up at 100 percent of the M365 base regardless of adoption. Acquired company seat sweep without reconciliation. Service account inflation. Plan oversizing through automatic E5 step ups. Add on True Up for products outside the deployment plan. And the True Up reporting from the Microsoft LSP without buyer side validation.
Microsoft 365 Copilot True Up follows the same anniversary mechanic as M365. The buyer side reports active Copilot seats above the EA baseline. Microsoft invoices the incremental at the held Copilot price. The Copilot True Up is the largest single inflation risk in 2026 because account teams routinely report 100 percent of M365 base as Copilot consumption. The buyer side must validate against adoption telemetry.
Yes. The True Up reporting window includes a buyer side validation phase. The buyer must reconcile the LSP submitted report against M365 admin center activity, Entra ID sign in logs, and the HR active employee list. Disputes typically resolve in 14 to 30 days. The buyer side has 30 days after anniversary to file disputes.
On a 10,000 seat EA with E5 plus Copilot, undisciplined True Up inflation typically costs 1.8 to 4.2 million dollars per anniversary. The largest single component is Copilot True Up at full M365 base. The second component is service account and acquired company sweep. Disciplined True Up programs contain inflation to under 3 percent of baseline.
