Hi MikeThomas1723,
I'm Nik, an independent advisor here to assist you with this.
May I know if you are trying to purchase Microsoft 365 business to your personal email address like (Gmail, Outlook, Hotmail, Live etc or work/school account (your organization IT department manages)?
Have you purchased a private domain(purchased from domain provider e.g. GoDaddy) and registered to your organization?
Regards
Nik
