QB Issue Resolution:

I can help you change your customer’s demographic information.


I have good news for you. There’s an Add or Edit Multiple List Entries feature in QuickBooks. This allows you to update multiple customer’s email or address. Once saved, the existing transactions will have the new information.


Here’s how to edit your customer details in bulk:

  1. Click Lists.
  2. Choose Add/Edit Multiple List Entries.
  3. Run through the list and update the necessary information.
  4. Click Save Changes.


Go back to your customer list and open the an existing invoice:

  1. Click Customers.
  2. Choose Customer Center.
  3. Select the customer.
  4. You can see that the address and email are updated.
  5. Open an existing invoice.

That should save your time and help you in changing the demographic information of your customers, dtinsley.
