Hi @Damien
Welcome Microsoft Q&A forum
I understand your company wants to switch Microsoft 365 billing from Rackspace to Microsoft directly to save costs. If you're not under a current contract with Rackspace, you are free to transition your billing. Here are a few steps to make it happen:
1.Check Admin Access: Ensure you have Global Admin rights in the M365 Admin Center. If not, contact Rackspace to grant access.
2.Contact Rackspace to inform them you want to stop their M365 billing service. Request:
-Tenant ID and M365 license details.
-Confirmation that no contract obligations remain.
3.Contact Microsoft: please refer this link and contact Microsoft to request a switch to direct billing. Microsoft will assist with:
-Verifying your tenant.
-Setting up a new payment method (credit card/bank transfer).
-Transferring licenses without service interruption.
4.Set Up Billing with Microsoft:
-Go to M365 Admin Center, navigate to Billing > Invoices & Payments.
-Add a payment method and purchase/assign M365 licenses.
5.Verify After Transition:
-Confirm users can still access email, Teams, OneDrive, etc.
-Check the first Microsoft invoice to ensure no duplicate charges.
