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:

3. Select the Contact Us button.

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.
