Welcome emails after purchasing domain

[BCurrier]

Hello,
The other day someone went into my company's storefront (which I still don't know how to view), and they tried starting a new account. They clicked that they already owned a domain and the account was setup. They received a welcome email, and an email with a confirmation number and a receipt. In that second email, it said this is not your login/pass info and it would come in another email. That email never got sent out.
--How do I make it so that email gets sent out?
and
--How do i view my company's storefront?
Thank you in advance for your time.

Is your company using Plesk billing module as the store front or you have a custom third party billing application?
