How do I upgrade my Quickbooks subscription to essentials?

Quickbooks is not an Apple owned service or application.

You'll either need to look for an upgrade button within the app or attempt to view your subscriptions associated with your Apple ID through the App Store.

Please:

1. Open the App Store
2. Tap on your Apple ID profile (upper right corner)
3. Tap on Subscriptions
4. Tap on the app you want to renew or update your subscription for.

If you don't see quickbooks there you'll have to go to their website for more assistance with upgrading your plan.
