Navigating B2B eCommerce processes can be quite daunting. All you want to do is buy critical supplies for your department, but instead, you have to wade through complex purchase process documentation that seems impossible to decipher. Ever felt like “punching” your way through those PunchOut catalogs, invoices, purchase orders, and the myriad other Excel sheets being thrown at you? Don’t worry; we have got you covered!
This article breaks down the differences between PunchOut and traditional hosted catalogs, shedding light on how they influence purchasing decisions, costs, and timelines.
Key Highlights
- Catalogs in B2B eCommerce serve as detailed online products and services data tailored for complex purchasing needs.
- Hosted Catalogs are stored within the buyer’s procurement system, offering a workflow-integrated and data-enrichment content management approach with updates.
- PunchOut Catalogs direct users to supplier-managed eCommerce sites with real-time product and pricing, ensuring accuracy and flexibility.
- Hosted catalogs may lag in updating item information and prices, while PunchOut catalogs always reflect current supplier data.
- Hosted catalogs are simpler to integrate but require buyer-side management, whereas PunchOut catalogs reduce maintenance but are challenging to regulate.
- Vroozi combines the strengths of hosted and PunchOut catalogs, empowering procurement teams with streamlined workflows, reduced errors, and centralized expertise.
What are Catalogs in B2B ecommerce?
In B2B eCommerce, the term “catalog” indicates a data collection of products or services that enable digital transactions. Think of it as the online equivalent of a printed catalog but tailored to meet an organization’s more complex purchasing needs. Alongside detailed information about each product, such as specifications and pricing, it includes features like bulk pricing, availability, and ordering options. The catalog can be accessed either on the supplier’s website or through the buyer’s procurement software.

What Are Hosted and PunchOut Catalogs?
If you access catalogs from your procurement system, you will find two main types — hosted and PunchOut.
Hosted catalogs
Hosted catalogs are stored directly within your procurement system. The supplier delivers the product and service information by upload or integration, and you can access the catalog as part of your existing workflow.
Here’s how it works:
- Companies curate catalog content from approved, preferred, and contracted suppliers.
- You check item information in your procurement software.
- You select the items you want to purchase and generate a purchase request document.
- The manager approves the document and creates a purchase order.
- You send the purchase order to the supplier and receive the goods .
- The Accounts Payable team pays the invoice based on the approved amounts and quantities received .
PunchOut catalogs
PunchOut catalogs integrate the procurement system with the supplier’s website through a secure link. Once you browse and select products, items from your shopping cart must be transferred back to your procurement system for approval and processing.
Here’s how it works:
- You “PunchOut” to the supplier website using a secure login.
- After you select the items you want to purchase and check out, your cart data is automatically transferred back to your procurement software.
- The manager approves the document and creates a purchase order.
- You email the purchase order to the supplier and receive the products. The Accounts team pays the invoice after matching the invoice to the expected pricing and quantity received.

PunchOut Catalogs vs. Regular Hosted Catalogs — Key differences
PunchOut catalogs and hosted catalogs primarily differ in data storage and management.
Item information
Hosted catalog item data is transferred from the supplier. If the supplier changes item details, like price or specification changes, the information may not be updated immediately in your procurement system. Sometimes, this can result in out-of-stock items added to the cart or a price difference in the final invoice.
In contrast, PunchOut catalog item data is always up-to-date, as the information comes straight from the supplier’s website. There is a significant reduction in downstream process delays eg: due to price differences.
Item pricing
Hosted catalog pricing is based on the price at the last update. In contrast, the supplier has more control over pricing and promotional information in the PunchOut catalog. They can offer discounts, promotional codes, and clearance sales. You may get deals and offers on PunchOut catalogs that you wouldn’t get with hosted ones, but it also means your employees could purchase items outside of agreed-upon contracts.
We summarize the pros and cons of both catalogs in relation to product listing below.

Implementation
Integrating PunchOut systems in procurement software is not a simple task. Ideally, you want procurement software to automatically import cart data from third-party systems and automate further steps in the purchase process. When suppliers offer PunchOut, they may require order, invoice, and other document integration. Plus, data must sometimes be synchronized with ERP systems, such as material masters, categories, and accounting.
Hence, PunchOut requires close collaboration between the procurement software team and your vendors. For example, Vroozi supplier onboarding services work with suppliers to set up your account, integrate catalog data and documents, and test everything. Every procurement software may not have the same level of hands-on onboarding services.
Buyer-side management
Buyers manage and maintain hosted catalogs with supplier collaboration. When suppliers make pricing or other changes to their catalogs, they publish them to their buyers or buyers’ systems. This usually means an administrator and/or category manager from your company has to review and approve the changes before they are visible to employees in the procurement software. PunchOut catalogs require no such management, as changes are directly visible to the employees.

Frequently Asked Questions
What is a PunchOut catalog?
A PunchOut catalog is an external, supplier-managed eCommerce site linked to a buyer’s procurement system. It allows users to browse and shop on the supplier’s website while ensuring compliance with procurement policies. Once items are selected, cart details are transferred back into the procurement system for approvals and order processing.
What is a hosted catalog?
A hosted catalog is a supplier-provided product list stored directly within a buyer’s procurement system. It includes product details, prices, and specifications and is integrated into the procurement workflow. Unlike PunchOut catalogs, hosted catalogs require manual updates for changes, making them less dynamic but simpler to manage initially.
What are the benefits of a PunchOut catalog?
PunchOut catalogs offer real-time access to product and pricing information directly from the supplier’s site. They enable dynamic pricing, including discounts and promotions, reduce manual data entry, and eliminate the need for catalog maintenance. This improves transparency and streamlines purchasing workflows.
What is the difference between a static and a PunchOut catalog?
A static catalog, like a hosted catalog, contains preloaded product information that may require manual updates for changes. In contrast, a PunchOut catalog provides live, supplier-managed data, including up-to-date pricing and product availability, ensuring accuracy and eliminating the need for frequent updates by the buyer.
Is EDI the same as PunchOut?
No, EDI and PunchOut are different. EDI is a system for electronically exchanging business documents, such as purchase orders and invoices, between organizations. PunchOut, on the other hand, allows buyers to access supplier-managed online catalogs from their procurement system for real-time shopping. EDI focuses on document exchange, while PunchOut focuses on catalog integration. However, some punchout suppliers may require cXML document exchange for orders and invoices.
