,Hi Ammar100,

Thank you for clarifying your concern. I'll be happy to continue to help you.

If you're using QuickBooks Desktop, you can edit your customer profiles in batches using these steps:

1. Click the Lists menu and select Add/Edit Multiple List Entries.
2. From the List drop list, select Customers.
3. From the View drop list, select All Customers or only choose the active ones.
4. Click the cell/s of the customer that you want to edit and enter the details you want to put in, and do the same thing to other cells and for the rest of your customers.
5. Click Save Changes.

If you're on QuickBooks Online, you're unable to edit customers in batches. That's why we suggest sending feedback to our developers so this will be considered in future updates.

We're just right here if you need more help with your customers' list. Take care and have a good one!
