New tenant, how to prioritize

Iron Contributor
I have a tenant that only have teams free licenses.

I am now looking to upgrade to business basic.
We are about ten users.

We have a domain and mail service at another provider.
But i dont know if i will mess things up if i connect our domain to the tenant before we get license for mail in o365. Or can i use our domain on the tenant and then later when we get the licence migrate mail to office365?

What order to do stuff in?

You can verify the domain now, as long as you don't change the MX record (and don't provision any mailboxes for now), nothing will change.
