Ive have been deleting the pdf attached invoice when emailing invoices so that customers are forced to view on line and download the invoice. This way I was assurded that the custome did infact, recieve and viewe the invoice.
This would update in the invoice Activity history. This update seems to be no longer working which means that I now have no way of proving that an invoice has in fact been viewed by the customer. Surly a read receipt should be an absolute mimium requirement for proof of deliverly. im hoping that this is just a temporary issue that will be resolved quickly. Otherwise, this will be just another step backwards.
