I would like to know why the increase rates of my subscription?

Thanks for posting in the Intuit Community, @rsnorthernservic.

I’d love to assist checking the charges associated with your account. However, billing and subscription concerns require personal verification which can only be done by our Customer Care Team. They’ll need to gather personal data to pull up billing, which we are unable to do in this public forum.

To contact them, here's how:

1. Click the Help icon on the top right.
2. Click Contact Us button at the bottom.
3. Enter a short description about your concern.
4. Click on Let's talk.
5. Choose the method on how you'd be connected to support.

Additionally, I want you to get the most out of QuickBooks for your business. You can check some articles that are designed to help you get acclimated with the software. They can be accessed at the following link: QuickBooks Tutorials.

If there's anything else I can do for you, let me know by commenting below. I'd be happy to further assist you. Have a great day.

Your discounted period is expired and you have to pay in regular price now. If you wish to keep the lower price, you will need another effort. Utilize the 3rd party tool to migrate your data between QBO accounts.

Once you are ready to proceed, open a NEW QBO account with current discounted plan for up to 3 months.
