# Keep teams online. Keep service in view.

## Assign responsibility. Verify the lifecycle.

Connect the company plan to the employee lifecycle.

### Define entitlement before rollout.

Record who uses the service, who pays and who approves changes. Agree on the ownership and transfer policy for any personal or company number.

### Keep the assignment authorized.

Link the employee to the approved offer and the fulfilled service. Deliver credentials privately and let support identify the allocation without asking for an activation code.

### Complete offboarding in each system.

Revoke company access, transfer or terminate the service and resolve billing through their separate owners. Keep unfinished number-transfer or financial work visible after the account closes.
