All the details of your PSAI plan are provided for your reference within your PSAI admin portal. To view the page, simply click Account in the lower left corner.

Then click Billing & Plan.

At the bottom of the Billing & Plan page, you'll be able to see your current plan, what's included, and the cost of additional features beyond the subscription allotment.

Don't want any unexpected overage fees? Leave the Enable Overages box unchecked, and the feature will deactivate as soon as you reach your monthly limit.
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.
