# Purchase Plan: Upgrade Your AI Agent Features

> Manage your ZynfoAI subscription, upgrade between pricing tiers, purchase AI token add-ons, and review billing cycles and invoices for your agents.

# Managing Your Plan

Your active subscription tier strictly dictates your platform feature limits, such as how many active AI agents you can deploy, available integrations, and your monthly AI token allowance.

Navigate to the **Purchase Plan** page (`/purchase-plan`) to manage your subscription securely.

## Upgrading Your Subscription

If you are hitting your monthly token limits or need access to premium enterprise features (like Custom CSS or advanced CRM integrations), you can upgrade your plan tier at any time. Prorated charges will be applied automatically to your payment method on file.

## Buying Credit Add-ons

If you are entirely satisfied with your current plan's features but simply need more AI tokens for an exceptionally busy month, you can easily purchase one-off **Credit Packs** without permanently changing your base subscription tier.

## Managing Billing Cycles

You can seamlessly switch between Monthly and Annual billing frequencies on this page. Opting for annual billing typically provides a significant percentage discount over the standard monthly rate.
