Another outcome is an increase in efficiency; the AP department can instantly find an invoice without having to waste time chasing the business users. With approximately 70% of the invoices now matching the PO immediately, a considerable amount of invoices only require scanning, after which the process is entirely automated. This efficiency has directly resulted in a reduction in the number of people required in the Accounts Payable department; before the system was installed the team consisted of 13 people and there have been reductions in headcount, as the AP manager substantiates: "The IMS system has increased efficiency in our Accounts Payable department to such an extent that on full implementation we expect to reduce our headcount by 4."
Types of Electronic Invoices _ An electronic invoice is one which meets the same requirements that apply to invoices issued on paper, except that it is presented in electronic format and its authenticity and integrity are guaranteed. In order to guarantee a document's authenticity and integrity, there are three possible methods: Utilization of a recognized digital signature, which is based on a recognized certificate and generated using a secure device for creating signatures. Remittance through an "EDI" system, which ensures integrity and authenticity. Use of another system which, in the opinion of the Auditing Department of the State Tax Agency, ensures authenticity and integrity, whenever the taxpayer issuing the invoice has applied for Agency approval of the system in question. In general, the use of a recognized electronic signature is considered to be an essential element of electronic invoices.
