Thank you for sharing those details, need memory
I understand that managing multiple customers can be time-consuming, and finding specific contacts should also be easy with the search function.
While there are no particular attributes that you can use to look for specific customers, you can use a combination of name, address, and phone number to utilize the Search field. For example, you can type "John 2600 Marine Way" to find John's contact details.
On the other hand, you can also export customer data if you want a more specific or the capability to customize information. Here's an article you can use as a reference: Export customer data to Excel.
I'm also adding this link to learn how you can add, edit, delete, or merge customers in QuickBooks: Add and manage customers in QuickBooks Online.
