DENVER–(BUSINESS WIRE)–Oildex, a service of Transzap, Inc. (“Oildex”), today announced that it has acquired the Procure-to-Pay (P2P) business of Automatic Data Processing, Inc. (Nasdaq: ADP), combining two leading technology providers in the fast-growing financial supply chain automation sector.

The combined company, which will operate as Oildex, is a leader in the accounts payable (AP) and business-to-business (B2B) automation segment within the broader financial supply chain automation sector, with over 1,100 customers, a network of more than 50,000 suppliers, and key operation centers in the United States and Canada. It supports a product portfolio that is uniquely positioned to meet the advancing needs of enterprises to manage complex financial supply chains, particularly in the oil and gas industry, where companies have a long and successful track record of partnering with leading operators, suppliers, service providers, and mineral rights owners.

The combination of Oildex solutions and the OpenInvoice™ AP automation solution brings together a unique set of technologies to manage the financial supply chain and support financial documents and transactions, including invoices, payments, royalty check stubs, joint interest bills, run tickets, gas plant documents, and more.
