Monthly subscription by users count

Monthly subscription by users count

Hi,

We are a SaaS platform like you guys in Zoho.

We want to use Zoho subscriptions but we have p problem cause some of our clients are paying a deferent amount of money depends by their active users amount.

It means that Customer X can pay on January $200 for 5 users ( 4 times $50 ) and on February they will pay 250$ for 5 users. We need to manuslly update the users count in order to charge the right amount.

How can I manage it with Zoho Subscription?

Thanks
