Hi Sharon_BCT
Thanks for your post. The Sales Register search bar looks for information in any of the visible columns (invoice number, customer name, amount etc.). In the cardslist you will be able to search by address: Finding a customer or supplier.
Alternatively, if you want to have information on the ship to address in you customer sales, you could get this by exporting information to Excel and manually doing so. If you want to have a report that includes Sales and Ship to address you can go into the Sales [Customer Detail] > Insert/Modify Tab > Show/Hide > Select 'Ship To' address to show. I'll link Sales Reports and Customising Reports for reference.
