What is the common Punchout catalog process?

There are 6 common steps of the Punchout catalog.

Please note that the punchout process may vary slightly depending on the level of punchout integration.

punchout catalog processpunchout catalog process

Step 1: Buyer logs into e-procurement system

The process begins with the buyer logging into their e-procurement system. This is where they manage and initiate procurement activities.

Step 2: The buyer is redirected to the supplier’s e-commerce site

From the e-procurement system, the buyer is seamlessly redirected to the supplier’s e-commerce site. This integration allows for a smooth transition without the need for separate login credentials.

Step 3: Buyer starts browsing and adding items to the cart

Once on the supplier’s e-commerce site, the buyer can browse the catalog, view product details, and add desired items to their shopping cart. This stage involves selecting products that meet their procurement needs.

Step 4: Proceed to checkout, cart contents are transferred to the buyer's e-procurement system

After finalizing the selection of items, the buyer proceeds to the checkout. At this point, the contents of the shopping cart are transferred back to the buyer's e-procurement system. 

Step 5: Internal Purchase Requisition (PR) / Purchase Order (PO) generated and approved

Within the e-procurement system, an internal Purchase Requisition (PR) or Purchase Order (PO) is generated based on the cart contents. This PR/PO is then subject to the organization's approval workflow, ensuring that the procurement complies with internal policies and budget constraints. Once approved, the PO data is sent in the appropriate format from the buyer's e-procurement system to the supplier’s e-commerce site.

Step 6: Acknowledgement email sent to buyer and supplier team

Finally, an acknowledgment email is sent to both the buyer and the supplier team, confirming the receipt and processing of the order. This communication ensures that all parties are informed about the status of the procurement, facilitating transparency and coordination

Frequently Asked Questions (FAQs)

The main purpose of a Punchout catalog is to enable seamless and efficient procurement. With Punchout, purchasing teams can browse, select, and order products from a supplier without leaving their internal procurement software. The Punchout solution automatically updates product availability, pricing, and other relevant information, eliminating manual entry and reducing errors.

A Punchout catalog requires the following technical elements:

  • Procurement system compatibility: The supplier's Punchout catalog must integrate with the buyer’s procurement system, such as SAP, Ariba, Oracle, or Coupa.
  • Supported protocols: Punchout typically uses cXML (for Ariba and SAP systems) or OCI (for SAP systems).
  • Secure access: Ensure that authentication methods like SSO or token-based authentication are set up to secure access for buyers.
  • Real-time data integration: The catalog should provide real-time updates on product availability, pricing, and stock levels.
  • Customization: The ability to tailor the catalog interface, pricing, and content to suit the buyer’s needs and requirements.

The buyer and supplier must work together to create a catalog that meets the buyer's purchasing needs. The supplier builds and hosts this catalog on their e-commerce website, designed specifically for integration with the buyer’s procurement platform.

Here's how the buyer and supplier collaborate:

  • Requirement gathering: The buyer outlines their specific procurement requirements, including product categories, pricing structures, and any contract terms that need to be reflected in the Punchout catalog. The supplier needs to understand the buyer's preferences and procurement policies to build a suitable catalog.
  • Catalog customization: The supplier builds a customized catalog on their e-commerce website. This catalog is specifically designed for Punchout, showing only the products, pricing, and availability negotiated in the buyer’s contract. The supplier ensures that the catalog can integrate with the buyer's procurement system through a compatible Punchout protocol (like cXML or OCI).
  • Testing and integration: Both the buyer and supplier test the Punchout integration to ensure that when the buyer "punches out," they can browse, select, and transfer items to their internal procurement system seamlessly.
