SendPO is a site which was developed to help companies send, confirm and track purchase orders

SendPO is an online service that takes the frustration and worry out of the ordering process by providing confirmation that your PO was received. As entrepreneurs we've been involved in a lot of small businesses from manufacturing to software. We're passionate about small business and one common problem has been the frustration over parts that don't show up or orders that are never received. We hope we've created a simple yet elegant solution that will meet your needs.
SendPO is a site which was developed to help companies send, confirm and track purchase orders. It works thusly: you, a small to midsized business, upload your purchase order to SendPO. Next the vendor receives the email with a link to download the order; SendPO communicates and tracks the PO’s progress. Finally you’ll receive confirmation once the order is shipped. SendPO comes with a web printer feature to convert your PO’s to PDF files for easier uploading.
