Upgrading your account is as simple as adding stores or feeds. When adding a new store or feed, FeedPerfect will prompt you to upgrade your payment plan if necessary. To upgrade simply select a plan by choosing upgrade when prompted as below.

 To view your current plan, go to My Account->Billing Info

The Payment Plan drop down will list plans that you qualify for given your current usage. If you want to switch from Pro to Lite for example, first deactivate all but 3 feeds per store. You will then see both the Pro and Lite on the Billing Info tab. Simply select Lite and Save. Your billing will be prorated at the newer rate for the remainder of your billing cycle.
