You can reassign an invoice to a different customer in Workshop Software, as long as the invoice has not been processed. This guide shows you how.
Step 1: Save the Invoice
- Make sure the invoice is saved. The actions star will not appear on unsaved invoices.

Step 2: Open Change Customer
- Click the Actions star button in the top right corner of the invoice.
- Select Change Customer.

Step 3: Search for the New Customer
- Search for the new customer in the search field.
- The customer must already exist in the system — you cannot create a new customer from this screen.

Step 4: Confirm the Change
- Select the correct customer and click Confirm.
- The invoice will update with the new customer’s details.

Good to Know
- You can only change the customer on an unprocessed invoice. Once processed, the customer cannot be changed.
- The customer must already exist in the system before you can assign them. Create the customer first if needed.
- Changing the customer will update all customer-related fields on the invoice (name, address, contact details).
Frequently Asked Questions
Will vehicle details change when I switch customers?
The vehicle selection may need to be updated separately, as the new customer may have different vehicles on file.
Can I change the customer on a processed invoice?
No, processed invoices are locked. You would need to unprocess the invoice first or create a new invoice for the correct customer.
