How do I change the customer’s name on an invoice that’s already billed?

To change your customer’s name for an invoice:

• Go to the Invoices module on the left sidebar and click the invoice for which you want to change the customer’s name.
• Click the customer’s name on the invoice template. You will be taken to the customer’s Overview page.

• Click Edit on the top right corner of the page.
• Edit the Customer Display Name field.
• Click Save.

Now, the customer’s name will be updated in all the invoices, including those that are already billed, and in all other transactions as well.
