Gray Portal, an incoming e-Archive Solution, checks the mailbox of users every 15 minutes and detects e-archive invoices sent via e-mail. It separates the e-archive invoices it detects according to the companies and transfers them automatically to the relevant current customers in the SAP system. Thus, the processes of separating and transferring e-archive invoices to the system among all incoming mails by finance employees are eliminated. Since the invoices will be transferred automatically, the e-archive prevents the possibility of missed invoices and human-induced errors that may occur while entering information.
