Sometimes there is an error in the customer address when entering it in the store. As result an invoice has been created with the wrong customer address, however this is easy to correct.

On the PamBill Dashboard, go to "Customer Management" and find the customer that needs a correction. Edit the customer and save the changes.

Then go back to the PamBill Dashboard, now click on "Invoices". The invoice now has the correct customer data and can be sent.
