Hello Kingsleyjohn, If the accountant has taken over the billing it should in the cog>billing and subscription section no longer show you as paying. There should not be anything else you need to do.
However, you may see an allow option in that section if you do just click on allow.
You have clicked a link to a site outside of the QuickBooks or ProFile Communities. By clicking "Continue", you will leave the community and be taken to that site instead.
