We offer a variety of eCommerce solutions to help streamline your procure-to-pay processes.

    Punchout Catalog

    By integrating the McMaster-Carr punchout catalog with your system, buyers can access our full product offering from within your own procurement application. The punchout catalog mirrors our website, providing buyers with a familiar user experience, real-time pricing and availability, and the same rich product detail information available on McMaster.com. We can also integrate purchase orders and invoices. We support cXML, OCI, and EDI connections across more than 40 procurement platforms, including SAP Ariba, Coupa, Oracle, and Jaggaer.


    The McMaster-Carr product information API (Application Programming Interface) provides an external method for programmatically retrieving product information. Approved customers can import the rich product information that is available on McMaster.com into their own systems. The API also provides up-to-date product information when specifications change.
