Quick Summary
A procurement manager needs to reorder industrial supplies, but manual procurement can be full of inefficiencies and errors. Instead of navigating a vendor’s external website, PunchOut catalog connects the buyer’s eProcurement platform directly to the supplier’s online store.
So buyers can browse real-time inventory, negotiated pricing, and updated product data within their familiar interface. It eliminates manual data entry and automates the purchasing process according to corporate policies.
This blog explains what a PunchOut catalog is, how it works, its benefits, how to use it, real-world examples, and more. Let’s begin by understanding the PunchOut Catalog.
A PunchOut catalog is a B2B e-commerce solution that lets buyers “punch out” from their procurement system (like SAP Ariba) and shop directly on a supplier’s live website. They can see real-time products and pricing, then send the cart back to their procurement system so all approvals and workflows stay in place.
With this catalog, the buyer is essentially “punched out” from their procurement system to the supplier’s live catalog. There, they can view real-time pricing, inventory, and custom contracts. After item selection, the system transfers the cart back to the buyer’s internal procurement system. Once the items are approved, a purchase order (PO) is created.
A PunchOut catalog connects the buyer’s eProcurement system to a supplier’s online store. That ensures a seamless and compliant purchasing process. Here’s how it works.
Basically, PunchOut catalogs automate the entire B2B purchasing flow, from selection to approval. With it, you can reduce manual entry, prevent pricing discrepancies, and improve overall procurement control.
A PunchOut catalog delivers several benefits for both buyers and suppliers. Let’s discuss them.
PunchOut catalog is not a static PDF or a list of items within your procurement system. It’s a way to bring real-time supplier inventory into a company’s controlled purchasing process. That ensures an efficient B2B e-commerce.
So, you see, the PunchOut catalog is quite beneficial, but is it better than the Hosted catalog? How do they differ?
PunchOut catalogs and hosted catalogs both support B2B purchasing. But they operate very differently and serve unique procurement needs.
| PunchOut Catalog | Hosted Catalog | |
|---|---|---|
| Core Concept/Integration | Real-time connection to the supplier’s website. | Static product file uploaded to the buyer’s system. |
| Where Shopping Happens | On the supplier’s e-commerce site. | Inside the buyer’s procurement system. |
| Data & Pricing | Real-time. Always reflects current availability, pricing, and promotions. | Static. Only as current as the last file upload. It can be outdated quickly. |
| Product Range | Full, live catalog. Access to the supplier’s entire range, including search, filters, and images. | Limited, pre-selected subset. Only the items that the buyers chose to upload. |
| User Experience | Familiar, rich e-commerce experience. It can be different for each supplier. | Consistent, but often more basic, “spreadsheet-like” experience within the procurement tool. |
At a glance, a PunchOut catalog is a dynamic connection to the supplier’s own website. The user “punches out” to shop directly on the supplier’s online store.
However, the Hosted catalog is just a static, uploaded items list stored within the buyer’s procurement system. Essentially, the buyer never leaves their company platform.
While PunchOut catalogs are a useful B2B eCommerce tool overall, different industries utilize them in different ways. All of these suitable industries require complex, variable, or high-volume indirect procurement.
Hospitals and other healthcare facilities have some time-sensitive procurement needs, beyond just drugs and pharmaceuticals. They operate 24/7 and need immediate access to essential supplies, from syringes to specialized surgical kits.
With PunchOut catalogs, staff can quickly find the exact, pre-approved medical items with little to no risk. The items they choose won’t be non-compliant or out of stock.
How They Use PunchOut Catalogs
IT projects require specific, compatible, and rapidly evolving hardware and software. With PunchOut catalogs, engineers can configure complex systems with real-time pricing and availability. That ensures every order matches project specs, budget limits, and contract terms.
How They Use PunchOut Catalogs
Government spending is governed by strict compliance and transparency laws. PunchOut catalogs enforce pre-negotiated contracts with approved suppliers. It can help create an auditable trail for every purchase to prevent fraud and ensure public funds are spent properly.
How They Use PunchOut Catalogs
Two of the most important aspects of the HoReCa are consistency and cost control. With PunchOut catalogs, chefs and managers can order specific food brands and quantities at negotiated prices. Therefore, the menu items taste the same every time, while protecting profit margins.
How They Use PunchOut Catalogs
In any factory or manufacturing unit, downtime can be incredibly expensive. PunchOut catalogs provide immediate access to Maintenance, Repair, and Operations (MRO) supplies. So maintenance teams can quickly find and order the exact bearing, motor, or tool needed to get a production line running again.
How They Use PunchOut Catalogs
Universities and schools manage diverse needs, from classroom crayons to advanced lab equipment. With PunchOut catalogs, authorized staff and researchers can purchase specialized items with ease. Departmental budgets and approval workflows are automatically enforced.
How They Use PunchOut Catalogs
What these industries gain is policy-controlled spending, higher efficiency, more data accuracy, and an overall streamlined procurement.
If you belong to one of these industries and want supplier PunchOut catalogs in your system, get our B2B eCommerce development services. We’ll integrate this feature into your procurement process for more streamlined results.
To integrate PunchOut catalog, you need both a technical setup and operational alignment with the buyers’ procurement system. Here’s how you implement it.
First, identify which customers or procurement systems you need to support–like SAP Ariba, Oracle, Jaggaer, etc. Each of these systems has its own protocols (like OCI or cXML) and authentication methods. So the PunchOut integration must be configured accordingly.
By clarifying these needs early, you can easily determine the required accommodations. That means the product data, custom pricing rules, and buyer-specific workflows your PunchOut catalog must accommodate.
Next, you need to select an e-commerce development platform that can handle PunchOut catalog functionality either natively or through integrations. Commonly used platforms include Magento, Shopify Plus, BigCommerce, and more.
Select a platform supporting real-time pricing, customer-specific catalogs, and secure XML/API communication. There should also be some flexible integration options to meet enterprise procurement requirements.
After selecting and setting up the platform, you will configure the PunchOut catalog integration. Establish secure endpoints, mapping product data to buyer requirements, and enable the required authentication method. It can be a shared secret, certificate, or token-based.
Implement the core PunchOut messages, including:
With these messages, the buyers can punch out to your site, shop with contract pricing, and send the cart back to their eProcurement system.
Next up, you work within the buyer’s sandbox environment to validate every stage of the workflow:
Make sure to test variations in SKUs, pricing, quantities, and invalid credentials. That ensures your integration performs consistently under real-world conditions.
Make sure your internal teams understand how the PunchOut flow works and how PunchOut orders differ from standard e-commerce purchases. Train your sales, support, and operations teams for basic troubleshooting.
They should be clear on how orders move through the system, so they can assist the enterprise buyers confidently.
Last but not least, you move your PunchOut integration into production. Then monitor the transaction logs and verify the success of cart transfers and incoming purchase orders. Regularly update product content, pricing, and system configurations to maintain accuracy.

PepsiCo is one of the best examples of successful PunchOut e-commerce implementation.
PepsiCo has large B2B customers working in diverse and complex procurement environments. One of the customers had a strict requirement as part of the contract renewal. They wanted an eProcurement system integration. PepsiCo recognized the broader need for scalable B2B integrations to stay competitive.
So PepsiCo decided to connect its e-commerce storefront (powered by SAP Commerce Cloud) to buyers’ procurement platforms. They implemented both PunchOut catalog features and PO automation. Now, customers could shop via their preferred systems, and PepsiCo could streamline order-to-cash.
What was the Result?
This example shows that a PunchOut catalog can be a way to serve the shoppers as well as streamline the enterprise-grade workflows.
Even with a successful implementation workflow charted out, there may be some challenges with the PunchOut catalogs. Let’s look at a few common ones.
Connecting a supplier’s eCommerce platform to multiple buyer procurement systems (like SAP Ariba, Oracle, Jaggaer, etc.) can be complex. Each system uses different protocols and field-mapping rules.
How to Solve?
Use middleware or PunchOut integration platforms to standardize cXML/OCI communication. Maintain clear field-mapping documentation and test every round-trip in buyer sandboxes before going live. This round trip will be:
Session Setup → Product Browsing → Cart Return → PO Creation
Product details, pricing, inventory levels, and contract-specific rules can quickly become inconsistent if data isn’t centrally managed. Even small mismatches lead to cart rejection or PO errors.
How to Solve?
Adopt a centralized Product Information Management (PIM) or a synchronized catalog workflow. Also, automate updates wherever possible, so buyers can always see real-time, contract-correct info in the PunchOut session.
PunchOut integrations involve sensitive procurement data, authentication tokens, routing credentials, and order flows. Poor security opens the door to data breaches or unauthorized ordering.
How to Solve?
Implement HTTPS/TLS, IP allowlisting, role-based access, and encrypted shared secrets or certificates. Regularly rotate credentials and audit logs to ensure compliance with buyer security standards.
