Cloud & Microsoft 365, quoted three ways.

Per mailbox

Shared mailboxes, resource accounts and the Entra objects that carry no mailbox at all but still need governing.

Per tenant, flat

Growth. A flat tenant fee is cheap at 40 seats and quietly expensive at 90, and the re-tier trigger is rarely written down.

Project fee for migration

Cutover weekend labour, mailbox remediation, and the PST backlog nobody scoped. Ask what happens on the second attempt.

Licence resale margin

That the management fee looks low because the margin sits on the licences. Ask for the CSP price and the service fee as two numbers.

Are Microsoft licences resold with a margin, and is that margin disclosed separately?

Who administers the tenant, and do we retain Global Administrator?

Is Exchange Online / SharePoint backup included, or assumed to be Microsoft's job?

What is the fixed price of the migration if the first cutover fails?

You describe the environment once

Headcount, endpoints, servers, what already lives in the cloud, and any compliance obligation. Two minutes.

We invite three or four providers

MSPs that work your area, your company size, and your regulatory profile. Never more than four, so nobody is cold-calling you.

We normalize what comes back

Per-user, per-device, and flat-rate bids all converted to a common cost per endpoint, with every carve-out and exclusion flagged.

You get the tabulation

One sheet, with contacts. Take the discovery calls you want, ignore the rest. Nothing is owed either way.
