Correct customer or invoice address details

Use this when a customer reports a wrong name, email address, or billing address, or when an invoice should have used a different address.

Order overview with customer, payment, document, and booking actions — Use the order overview to inspect the commercial record and choose the next safe action.

Before you start

Confirm you are editing the right customer record. If the same person appears more than once, read Clean up duplicate customer records first.
Understand the key constraint: invoices that already exist keep the customer and address details they were created with. Corrections apply to future emails and documents.

Edit the customer record

Open Sales > Customers and open the customer.
Select Edit in the customer header to open the edit form.
Correct fields such as Salutation, First name, Last name, Company, Email, Telephone, Mobile, and Tax code.
Save. A confirmation shows that the customer information was updated.

To manage addresses, open the customer's Addresses tab. There you can select Add new address, edit an existing address, and mark an address as the default with Use as default billing address or Use as default shipping address.

Choose the address used on an order

Each order stores which of the customer's addresses it uses:

Open Sales > Orders and open the order.
In the Customer Information sidebar, change the address selected under Billing Address or Shipping Address.

What cannot change after an invoice exists

Once an invoice has been created for the order:

The invoice document keeps the name and address it was created with. Editing the customer afterward does not rewrite the existing invoice.
On the invoice itself, staff can change the payment status (for example Mark invoice as paid) and download the document, but not the customer or address on it.
Deleting a customer anonymizes their details on orders, but existing invoice PDFs remain untouched.

If a finalized invoice must show different details, follow your team's refund and invoice-correction process for the order, or contact ToucanTix support with the order and invoice numbers.

Expected result

The customer record shows the corrected details, new emails go to the corrected address, and orders finalized from now on use the corrected billing address. Existing invoices are unchanged.

Troubleshooting

Problem	What to check
Confirmation email still went to the old email	Whether the customer record was saved before resending, and the recipient shown in the order History.
Invoice shows the old address	When the invoice was created; invoices keep the details from creation time.
Cannot edit the customer	Your role's permission to update customers.
Two records exist for the same customer	Do not merge manually; follow the duplicate cleanup process.
