At least one address type must be set to print on invoice in order to save addresses from the POS.
Info: Addresses have their own save button!
When you begin to type, it will appear at the far right end of the row. You must save these before saving the whole form. Once one line is saved, another will appear. You may save multiple addresses to any supplier or customer.
To change your Address types options, navigate to Settings → Customer Registry Settings / Address Types. If you cannot see this option, contact your administrator.
Tip: To allow a user group to adjust the Address Types Settings, add this to their User Group permissions. This can be done by admistrator.
