Switching Microsoft CSP Partners: How a Microsoft 365 Subscription Transfer Works, What Changes, and What Does Not

A Microsoft 365 tenant is yours. Your users, mailboxes, SharePoint sites, Entra ID configuration and security policies live in it regardless of who sells you the licenses. A CSP partner is the reseller of record for the subscriptions in that tenant: the partner places the orders with Microsoft, invoices you, and is your first line of support.

A partner-to-partner transfer moves that reseller relationship for your existing New Commerce (NCE) license-based subscriptions from the outgoing partner to the incoming one. Microsoft documents the mechanics in its Partner Center articles on transferring subscriptions: the new partner sends you a reseller relationship request, an administrator in your tenant accepts it, and Microsoft moves the subscriptions. Microsoft's flow completes transfers within 72 hours of acceptance; in our experience it is usually within two business days.

What the transfer is not: a tenant migration, a data migration or a re-implementation. No mailbox moves, no password resets, no client reconfiguration, no downtime. It is also not an Enterprise Agreement exit or an MCA-E move; those are different Microsoft programs, and our Enterprise Agreement to CSP or MCA-E Transition Advisory covers that path. Azure consumption billed through a partner's Azure plan follows a separate Microsoft process as well.

Three things change.

Billing. Your invoice comes from the new partner. Ours comes from IT Partner LLC in USD, monthly by default or annual if your finance team prefers, itemized by SKU and license count so it reconciles against the admin center. Your old partner's billing stops with their final invoice; there is no period of double billing.

Support. The partner you call when Exchange Online misbehaves or an account is compromised is now the new one. What that support includes is a contract question, so ask for it in writing. For organizations that buy their licensing through us, unlimited break-fix support during business hours is included at no extra charge, under a published one-business-hour first-response commitment; 24/7 coverage is a separately priced support agreement. Both are recorded in our facts register.

The admin relationship. A partner's access to your tenant runs on Microsoft's granular delegated admin privileges model, GDAP. It is separate from the reseller relationship: accepting a reseller relationship request grants no access inside your tenant by itself, and admin roles are a further request that you approve. Our authorization page shows the actual screens, and our published access policy states the default we ask for: Microsoft's standard starter relationship, largely read-only, with anything more requested per task, time-bound, and revocable by you in one click in the admin center. Your outgoing partner's GDAP relationship does not end automatically when the subscriptions move; removing it is a step on your list below.

Your tenant ID, domains, users, groups, mailboxes, files, Conditional Access policies, Intune configuration and audit history are untouched. The subscriptions are the same SKUs at the same quantities with the same service plans.

The commitment terms carry over unchanged. NCE terms belong to Microsoft's program, not to the partner: an annual commitment you made in March still ends the following March after you switch, and a transfer never cancels or restarts a term. This is why the pre-transfer inventory matters. You want every end date in writing before you accept anything, and where it is cleaner to time the switch against a renewal, that is a scheduling decision rather than a constraint.

The price is Microsoft's. Microsoft publishes list prices for NCE subscriptions and they are the same direct or through a partner; what differs between partners is whether they sell at list or above it, and what they include around the license. We sell at list and say so in our facts register; every subscription page on this site names the monthly price list it binds to. If your current partner's price is above list, the pre-transfer comparison shows it. To see your own numbers, the comparison calculator for organizations buying through another partner takes your monthly spend or seat counts and compares line by line.

1. Export your subscriptions. In the Microsoft 365 admin center, under Billing and Your products, list every subscription with quantity, term, end date and renewal setting. This is the document the incoming partner reconciles against, and it shows whether an annual term ends next month or in eleven.
2. Confirm who can accept. A Global Administrator accepts the reseller relationship request. Make sure that person knows the request is coming and from whom; a request from an unexpected organization should be treated as phishing until proven otherwise.
3. Ask your current partner three questions. Is anything priced below list under an arrangement that ends with the relationship? Does any add-on ride on the partner's own tenant, such as a resold backup tool that is not a Microsoft subscription? What GDAP relationship do they hold, and when does it expire?
4. Sign two documents. Microsoft's Customer Agreement, which every CSP customer signs regardless of partner, and the new partner's services agreement. Ours is short; read the exit terms before you sign anyone's.
5. Accept the reseller relationship request. It is a link into your own admin center and takes a couple of minutes.
6. Decide on access. Approve a GDAP request only if you want the partner to do work in the tenant, and compare the roles requested against the partner's published policy; our GDAP review guide shows how.
7. Add the vendor. In practice, accounts payable adding a new supplier is the slowest step in the whole switch.
8. After the transfer, verify. Check the SKU-by-SKU confirmation against your export, remove the outgoing partner under Settings and Partner relationships, and put every renewal date in a calendar someone owns.

The whole sequence takes two to five business days on the transfer page timeline: a discovery call, a documented proposal, the two agreements, the transfer, and a welcome call. Our CSP billing switch service runs the partner's side of that sequence at no charge for organizations moving their billing to us.

A transfer you can make is a transfer you can unmake: the same customer-approved workflow moves subscriptions to another partner or back to Microsoft, and no partner can block it. NCE commitments come with you either way; leaving a partner never ends a term early.

Ask any partner you are evaluating to put their exit terms in writing. Ours are in the no-lock-in entry of our facts register: no minimum term and no termination fee on services, settlement of outstanding approved invoices the only obligation, and outbound transfers executed under Microsoft's workflow. The buyer's checklist for choosing a CSP partner covers the rest of the evaluation, and why buy from a CSP instead of direct covers the question underneath it.

Will our users notice anything?

No. The change is at the billing and partner layer. Same tenant, same sign-in, same mailboxes; nothing is reconfigured and nothing goes offline.

Can our current partner block or delay the transfer?

No. Microsoft's process is customer-approved: you accept the new relationship in your own admin center and the transfer proceeds. Telling your current partner is a courtesy, not a requirement.

What happens to an annual commitment we already made?

It keeps its end date and its quantity with the new partner. The moment to reduce seats or change terms is the renewal, which is why the transfer confirmation comes with a renewal calendar.

Does the price change?

Microsoft's list price is the same in every channel. Whether your invoice changes depends on whether your current partner sells at list, above it, or with a discount that ends with the relationship.

What access does the new partner get?

None by default. The reseller relationship connects the two tenants for ordering and billing; admin roles are a separate GDAP request you approve, scoped and time-bound, and revocable by you.
