Hi Tony,

Welcome to the Box Community!

We're making sure that our Box plans are flexible depending in your needs, that's why we offer Business plans designed with unlimited storage.

I do want to mention that all of our Business-level Plans require a minimum  of 3 seats and currently, we do not offer these subscription plans for 1 or 2 users. It is not required for all 3 seats be used, but we do require that the subscription is set up for at least 3 users. For more information on our different account types, you can refer to www.box.com/pricing. 

To learn more on how to upgrade your account, please take a look at this article:  Upgrading your Box Account

Thanks for posting and let us know how else we can help!

Best,
