Thanks for joining the Community. I'd be glad to assist you with configuring your account.
Just to clarify, are you trying to set up a UK QuickBooks Online account? If so, it sounds like you may have signed up for the US version. These versions are optimized and configured for their respective regions, so options such as postal codes can vary. Additionally, you can signup for the UK version at the following link: QuickBooks UK.
I'm also including an article that includes the steps for canceling the account so as to avoid any future charges: How to Cancel Your Subscription.
Should you have meant something else, please let me know by posting a comment below and I'll happy to continue assisting. Have a good one.
My son is in USA as is his business, he uses quickbooks online. I have been invited and followed the link, but my details are not accepted.. telephone & postcode. I am wanting to assist as a bookkeeper and live in the uk.
