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."
Although we know perfectly well what an invoice is, its technical definition is "a document that reflects the delivery of a product or the provision of services, along with the due date and the amount to be paid in consideration." All invoices, regardless of the way in which they are sent (whether on paper or in electronic format), must include a series of mandatory fields. Article 6 of Royal Decree number 1496, Spanish law, which regulates the content of an invoice, establishes these fields as: Invoice number. Delivery date. Sender's and recipient's legal name. Sender's and recipient's Tax ID number. Sender's and recipient's legal address. Transaction description (tax base). Tax rate. Tax amount. Date of service (if different from the delivery date)
