Thanks for joining the thread, @ssantiago.

The field on the Bill to section when printing an invoice depends on the information showing on the Billing address section when creating the invoice. To avoid double names, I recommend checking the data displaying on Billing address section and delete if name posted twice.

To know more about creating an invoice, see this link: Create invoices in QuickBooks Online.

If you'd want to personalise it, you can do so, visit this resource: Customise invoices, quotes, and sales receipts in QuickBooks Online.
