Open Invoicing - e-invoicingOasis Petroleum is excited to offer e-invoicing alternatives to standard invoice submission.  To accomplish this, Oasis has teamed up with Automatic Data Processing (“ADP”) to offer access to their vast network of Oil & Gas e-suppliers (“Procure-to-Pay”).  E-invoicing enables instantaneous invoice submission (no stamps and mail) with direct importing of your invoice into the Oasis workflow approval system which not only enables secure, fast delivery of your invoice, but allows Oasis to research, approve, and pay e-invoice vendors via ACH for speedy direct deposit to the vendor’s designated bank account.
