From the Admin Portal as a client using the SaaS platform, when you click on Billing or Upgrade it takes you to "Packages" /admin/billing/packages and it should them all, it doesn't update to changes made from Super Admin as to what's available or if you change Max Storage/Employees and there is no button or link for them to Upgrade. So, I was playing around and it says I need to upgrade my account to add the employee, and when I do it takes me to this page but nothing can be done. Also, the Super Admin cannot change someone's package either. I cannot imagine that's a feature, looks like a bug where there was a piece that didn't make it into production.
