If the job is not in Edit mode, (and not yet Booked Out Completed), simply edit the job then click the Customer Address to refresh it, or choose Customer menu > Clear from Form, then re-select the customer.
If the job is Booked Out Completed, it will have an invoice number and is protected. You may void the invoice then refresh the customer.
1. From the Action Menu, choose VOID invoice or Credit Note
2. Choose Action > Edit (F4)
3. On the Main Form, in the Customer box, click the Customer's Address, then OK
4. Book the job out again
Tip: Pay attention to the Tax Date if you want to back-date the Invoice when you book it out.
The invoice address box is disabled, we need to specify a different invoice address to the customer's address
