We accidently changed a vendors bill to address, now the incorrect billing address is showing on all invoices even though we went back and edited the billing address

An Invoice is related to Customers, and a Bill is Related to vendors.  Maybe you have the vendor duplicated as a customer?

Welcome to the Community, takiryjp.

There are a few factors why you're getting the Suspended alert in QuickBooks Desktop. Below are the lists:

• QuickBooks is not updated.
• If the automatic renewal isn't successful, or the credit card or bank account on file is outdated.
• Intuit is having trouble getting authorization with your payroll billing information.
• You're using an incorrect Payroll tax table version.

To update your billing information, please follow the steps below:

1. In QuickBooks, go to Employees.
2. Select My Payroll Service, then Account/Billing Information.
3. Sign in using your Intuit Account login.
4. Select Billing Detail.
5. The level of information may vary depending on your contact role. If you don't see any information under the Billing Details box, this means that you're not the current billing contact. To change the holder or the billing contact, please contact us.
6. Select Edit billing info.
7. Enter your new billing information and select I Agree.
