All the details of your PSAI subscription are provided for your reference within your PSAI admin portal. Simply click Account in the lower left corner and then click My Subscription.
On the My Subscription page, you'll be able to view your subscription details, as shown below.
For each feature, you'll see the total allotment per month and, where applicable, the cost of each additional overage.
Don't want any overages? Uncheck the "Enable Overages" box to turn off the feature as soon as you reach your monthly allotment, preventing any additional unexpected fees from accruing.
If you're consistently running into overages for a certain feature, it might be more cost-effective to upgrade your PSAI subscription. Please fill out a help ticket to find out what your options are for upgrading.
