This project enables Drupal Commerce sites to process orders using the Open Catalog Interface (OCI) standard. This integration allows B2B customers to use their own procurement systems to purchase goods and services from a Drupal Commerce-powered store.
Makes it possible to do OCI checkout on a commerce site.
Open Catalog Interface (OCI) is one of the standard formats used by SAP Supplier Relationship Management, ORDIGES Purchase-to-Pay, Microsoft Dynamics AX and other ERP/Purchasing Systems when connecting to external punch-out catalogs.

Widely used in European countries, this makes it possible for B2B sales through this standard, using Drupal Commerce as the supplier of the store, and the customers own procurement system as the purchase portal.
