"Should I add the title name in customer column under deposit field. Because it's not displayed the title name once entry is saved.

Hi there, @shashank-kadam.

You've got me here to share some insights about adding a title for your customers' transaction in QuickBooks Online.

If you're referring to adding a title for your customers' names on any of their transactions, you can add it from their profile. Please see the screenshot attached for your reference: 

However, if you wish to change the Customer column to the title, this option is currently unavailable. The Customer is the default set up on all the sales transactions, including the deposit. To have the title show up, you may use it as the customers' name instead.

To give you more details on how to modify the customers' information in QuickBooks Online, please see this link: Learn how to add, delete, merge, and restore customers in QuickBooks Online.

On the other hand, I'm also adding here an article that you can check out about what are the things that can be customized when it comes to sales forms in QuickBooks Online: Personalize your sales forms and add the info that matters most to your business.

Let me know if you're referring to something else or if you have any other questions. I'll be right here to help. Have a lovely day!

Thank you.
