Microsoft 365 set up securely, licensed to what people actually use and run to one standard across the platform company and every add-on, so acquisitions join the same tenant without disrupting work.

Microsoft 365 is where most of a company’s work happens: email in Outlook, files in SharePoint and OneDrive, chat and meetings in Teams, and documents in Word and Excel. Managing it means keeping it licensed correctly, secured and supported, along with the laptops and phones people use to reach it.
For a PE-backed company, it means every location and add-on works in one tenant, nobody pays for licenses they don’t use, and the setup holds up when a buyer’s diligence team looks at it.
Can people log in, email and share files from the first day of new ownership?
How quickly can the business move out of the seller’s Microsoft 365 tenant?
How does an acquisition on Google Workspace or another tenant join ours?
Are we paying for the right licenses, and only the ones people use?
Are sign-ins, devices and data protected to one standard?
Will a buyer find a clean, well-run Microsoft 365 environment?
Is the tenant ready for Copilot, and is company data kept out of unapproved AI tools?
Five areas, run the same way at the platform company and every add-on.

Most providers resell licenses and answer tickets. Compello is a Microsoft partner that runs Microsoft 365 as part of the investment, with one senior team and one standard across the portfolio.
Our Microsoft practice is staffed by people who led in Microsoft’s Azure and Modern Workplace business units. We know the platform, the programs and the licensing.
Tenant moves are routine for us, from an 800-user tenant-to-tenant migration to seven or eight tenant and identity moves for a single client in 2026.
The senior team that diligences the deal and delivers the 100-day plan stays on to run Microsoft 365 through the hold.
Something we haven’t covered? A partner can answer it on a short call.
