Was my rate raised due to your failure to notify me that my bill was due? Dr Mike Kissick

God day, theranch.

One possible reason why the rate will increase is because of discounts. QuickBooks Online offers discounts, especially to those newly created accounts. The discounted price may depend as it changes from time to time. Though most of them are offered for a period of 3 months. 

Also, another possible reason is that you subscribe to QuickBooks Online Payroll. Please note there's an additional charge if you subscribe to payroll service. You can check the pricing here: https://quickbooks.intuit.com/pricing/.

You can also check your billing details so you can see and review the charges.

1. Go to the Gear icon and select Account and Settings.
2. Select the Billing and Subscription tab.
3. Choose the View Payment History hyperlink.

For additional questions about billing, I suggest contacting our Support Team so they can check it for you. QuickBooks Community doesn't have visibility of your billing and subscription information.

I'm just a post away if you need me. Have a great day!
