Hi Florence, have you tried updating the address while creating an invoice? If not, you can change it during the transaction. This will automatically save the new details for all future invoices.
To update this, click Create an invoice from your widgets and select Edit company. Update the address under the Customer-facing address section and click Save. If your customer-facing address is the same as your company address, you can make the changes there.

Let me know if you need anything else with QuickBooks Self-Employed. I’m available around the clock to help.
