Can we modify the Invoice document information to show Reference/Issue Date etc. instead of “Invoice number”; Invoice Date:" etc.
In Sales Quotes it is “Issue date:”; “Expiry date:” and “Reference” but in the Sales invoice it is “Invoice date:”; “Invoice number:”.
My question is can we not have Invoice the same as the quote information?
This should not be done through custom fields or through modifying the template/theme as those fields, not custom fields.
