I'll share a few information, girlcode-amy.
Thanks for being part of the QuickBooks family. I want to ensure you're connected to the right support who can provide detailed information on your subscription.
I am happy to assist you with some information regarding our pricing. Unfortunately, without reviewing your specific account, I can't determine why you were charged the full price for your subscription.
I would recommend contacting our QuickBooks Online Support. They will be able to look directly at your account in private and tell you why you're being charged for the full amount.
Also, you can get in touch with customer service if you have subscribed to your QuickBooks account directly from the Google Play Store for Android or the Apple App Store for IOS.
Let me include this blog to help you set up QuickBooks Online: Get started with QuickBooks Online.
If there are any further queries or concerns that I can assist you with, please leave a comment below. I would be happy to continue providing help and support. Best wishes to you.
