If you are running a small business and manages vendor invoices and payments manually, it may be wise to invest in an accounts payable automation software. An AP software will take care of the invoice capture for you (no manual keying required!) and it will flag or notify you every time you get invoices from a new vendor and/or duplicate invoices. The software also supports digital approval workflows and can be configured to send invoices, based on vendor, reference or amount, into a specific approval workflow – with one or several approvers.
