Thank you for bringing your question here in the Community, @carlawerner74. I'll provide you with the steps on how to search for a customer by their address in QuickBooks Online.
When using the search bar to look up a customer by their address, ensure to enter the address exactly as it was recorded. Double-check for accuracy in spacing and spelling.
If you've entered the correct address but are still encountering the issue, I recommend refreshing the page. Additionally, logging out of your QuickBooks Online account and then logging back in can help ensure that cached browser data isn't interfering with its functionality.
If you've entered the correct address but still cannot locate customers using it, try switching to another browser supported by QuickBooks.
This approach should help you successfully look up customers using their address in QuickBooks Online. If you have any additional questions, feel free to reply. I want to ensure all your needs and goals are fully covered.
