Laravel Cashier Many Users under One Subscription

Hi guys, I have a CRM where a Company Owner (@role owner) can subscribe using credit card to a plan. StripeCashier subscription is added to the Users table. So, the Owner subscription and access are easily maintained via Stripe. Now, the company owner can add other Users such as admin or manager under the same company. I would like to know whats the best way to block other users when the owner's subscription expire? THX!
