Oildex provides E-Business products that enable companies and their suppliers to automate business processes, and enhance the effectiveness of those processes through the Internet.  Oildex OpenInvoice is a software application that allows trading partners to collaboratively create and process invoices.


Setup in the OpenInvoice application requires that we take a small amount of general company information such as company name, address, employees, taxation numbers, and the product/services that the company provides.  The self-registration process takes approximately 15 minutes, at which time you will be provided a secure username and password to access the application. If required, Oildex will schedule a training session with you. Training typically takes place over the phone and takes approximately 30 minutes.
