+The **Limits** tab displays the usage limits for the Apify platform based on your current subscription plan. As you approach the defined limits, you will receive a notification about potential service suspension or overage charges. If your usage exceeds the specified limits, Apify platform services will be suspended to prevent incurring charges beyond your subscription plan.

+You can adjust the platform usage limits and enable overage, allowing you to continue using the platform beyond your subscription plan on a _pay-as-you-go_ basis. Any usage, beyond your plan will be charged as overage to your account.
