Hello, tjp79.
Since Dell is in charge of the billing, they are also responsible for the upgrade process. So you'll want to contact them to upgrade your current subscription so you can use the Product feature.
Though if you want to subscribe with us instead, you can cancel the subscription from Dell. For more information, please refer to this article: Upgrade your QuickBooks Online subscription.
In addition, you can also read this resource to help you handle your QuickBooks Online subscription. It includes steps if you need to update the card on file, change your subscription, or view your billing history: Manage billing, payment, and subscription info in QuickBooks Online.
Do you have any other questions about your products? Please let me know and I'll share some guides and details with you. Feel free to add any other concerns you might have as well.
