Upgrading your Product Feed subscription lets you unlock more features and higher limits without setting anything up from scratch. You’ll do everything from your Adtribes account, and the change takes effect right after purchase.
Steps to Upgrade
Sign in to the Adtribes Account that holds the subscription you want to upgrade. Go to Account → Subscription, find your Product Feed subscription, and click View to open the details.

Click Upgrade on the subscription details page

In the pop-up, select the plan that fits your needs, and click Proceed to complete the upgrade.

You’ll see the new plan on the Subscription page. A confirmation email and invoice will be sent to your account email.
That’s it. From Account → Subscription, open your Product Feed subscription with View, click Upgrade, choose a plan, and hit Proceed to finish. If you run into any issues, contact support, and they’ll help you complete the upgrade.
