What is PunchOut Catalog and How it works in B2B eCommerce

When your daily working routine includes ordering and buying stuff, making orders and adding them to the CRM becomes an additional challenge nobody likes. To relieve this unneeded stress, the PunchOut technology was invented. PunchOut is a popular procurement automation tool in the B2B sector that allows making purchases right from your common procurement tool. In this article, I will explain how it works, the advantages and disadvantages of the technology, and how to integrate it with a modern ecommerce portal.

Introduction to PunchOut Catalogs

The core idea of Punch Out is to export a product catalog from the supplier's ERP system or website to the buyer's ERP system or e-procurement application for convenient corporate purchasing. Let’s dive into more details to discover all ins and outs of the technology.

What is a PunchOut

PunchOut is a system where the seller’s product catalog is integrated with the buyer’s CRM or ERP system. It looks like a normal seller’s website built in your CRM or ERP but with some smart features. It allows customers to buy goods straight from their CRM with no need to log in, check out, create purchases in the system, and so on.

The technology was widely implemented in the 2000s, before the modern era of B2B ecommerce portals and marketplaces. Still, many large companies and government agencies actively use PunchOut because of its user-friendliness and the inertia of the established business processes in large companies. Accordingly, integrating PunchOut systems with modern B2B ecommerce portals and marketplaces has become vital.

Why is it called PunchOut

The name of the technology is literary related to the moment when you want to punch out from your tasks quickly! Instead of finishing your purchase by creating a purchase order and sending it to the accountant, you just put what you need in the cart as usual and punch out: the system will do the rest of the paperwork.

What is a PunchOut catalog

Basically, a PunchOut Catalog is a normal items catalog of the products the seller has in stock. The only difference is that it can link to the buyer’s e-procurement solution and grant easy access to all products on their website without leaving the buyer’s e-procurement system. All the functions of a standard catalog are present!

What is the purpose of a PunchOut

PunchOut catalogs provide benefits for both buyers and sellers: the buyer gets transparency of pricing and terms, a streamlined ordering process, and increased efficiency of the whole working process, while the seller gets more loyal clients and more purchases due to more convenience. This solution best fits the medium size and large companies that often buy for the following purposes:

  • To get tools and accessories to produce what they sell;
  • To get equipment for maintenance or repair;
  • To resell what they bought with some margins added;
  • Or just to standardize their procurement processes.

PunchOut catalogs allow buyers to easily browse and search for products from their preferred suppliers, all within their own procurement application. This can save much time compared to manually searching and ordering products.

They also provide sellers with a way to showcase their products and services to potential customers highly efficiently. By making it easy for buyers to find and compare PunchOut catalogs from different suppliers, sellers can increase their chances of winning business.

What is a B2B PunchOut

For B2B eCommerce, PunchOut technology is the easiest way to reach the target buyer easily. B2B PunchOut is actually just a working B2B eCommerce website optimized well to fit in the interface of the customer’s eProcurement solution.

B2B PunchOut is a complex system that requires fine configuration. However, many vendors offer this solution as a simple addon or extension.

eCommerce PunchOut not only makes it easier to purchase but also helps to build a personalized approach as the system identifies a buyer as an individual and can offer special pricing or related products for up sales and cross sales.

Punchout Catalogs, APIs, EDI - Technologies for B2B eCommerce

Although this post is about PunchOut technology, it's fair to point out that there are other ways to integrate vendor and buyer computerized trading systems in B2B. This includes using APIs and EDI, so I will briefly discuss them to expand your knowledge in this area.

In modern B2B commerce, there are several technologies for buyers to work with supplier directories. The choice of method depends on the digital maturity of the company, its size, established business practices, and the availability of an in-house development team that can implement the most advanced technologies on the customer side.

  • A hosted catalog is the simplest way to share vendors’ product catalogs with buyers. The vendor exports its product catalogs in a universal format, such as excel, and places them in a password-protected folder on the website for download. This is a static form of catalog data exchange. It is primitive because the information in these files is updated sporadically, and not all items in the catalog may have actual prices. The customer has to additionally contact the vendor's sales team to clarify the price and availability of the selected items.
  • APIs (application program interfaces) are a set of protocols that govern how one application can send a request to another. In other words, an API connects one machine and software to another via a local network or the Internet. API is widely used for software integration in many e-commerce applications. API is a peer-to-peer communication like PunchOut technology and doesn’t require an operator for exchange between a buyer and supplier.
  • EDI technology stands for electronic data interchange, which is the transmission of commercial information such as purchase orders, invoices, change requests, and so on in a standardized format that each partner's system can process. The advantages of EDI include improved competitiveness by forming relationships with suppliers and customers who use it. Currently, EDI is mainly implemented in the retail industry.

Is PunchOut an EDI?

EDI is not a peer-to-peer communication like PunchOut technology or API. It requires an EDI operator in the middle to exchange messages between a buyer and supplier. This is like the talk of two persons using mobile phones through an operator.

PunchOut, on the contrary, interacts directly from the buyer’s side to the seller’s eCommerce catalog, only verifying log-in details via a PunchOut gateway.

Moreover, EDI only offers the exchange of the static information like price lists and documents. It doesn’t offer any interactivity and shopping experience, as EDI is not a real-time technology.

Basically, EDI is a kind of an old-fashioned PunchOut version. They offer entirely different capabilities in terms of buying, which means PunchOut technology is a better solution.

What is ERP PunchOut?

A B2B PunchOut catalog is an e-procurement platform that allows clients to access a distributor's catalog from their ERP system. PunchOut-enabled customers do not have to leave their ERP system to order goods from a verified supplier.

What is PunchOut in a supply chain?

PunchOut technology makes it easier for supply chain specialists to purchase the correct goods. They use their usual procurement system to order exactly what was discussed with a supplier. This leads to the following improvements:

  • The company gets products from a reliable vendor.
  • The numbers are always correct as the system counts them automatically.
  • The whole supply chain works faster due to the ability to build invoices and purchase orders automatically, with no need to spend time doing it manually.

How Does a Punchout Catalog Work?

Technically, a PunchOut catalog is an online supplier catalog that is developed with an open catalog interface to support PunchOut procurement related to a customized PunchOut website. The PunchOut ecommerce solution enhances the structured relationship between an e-procurement system of the buyer or ERP and the vendor's storefront.

The PunchOut system is designed, so the vendor isn't notified when the customer makes any purchase. The buyer's e-procurement system serves as a processor for the items in the shopping cart. This makes it very easy for customers to migrate between different product catalogs.

It is important to note that a PunchOut catalog stands as the most effective way for customers to examine a vendor's catalog. Also, it's a convenient way to place orders using an e-procurement system.

PunchOut catalog explanation

The PunchOut Journey

A customer interested in buying a product leaves—or “punches out” of—their procurement application and moves to the seller's webspace or e-catalog. The buyer can then shop and add items to their cart while a connection is established between the buyer’s procurement application and the supplier’s web-based catalog.

When the buyer wants to place an order, the cart and items are sent back to the buyer's procurement application, and the customer does not follow a standard checkout procedure. Instead, the cart is sent back, and the order is placed through the application to the buyer organization for financial approval; once it is verified, a purchase order is created and sent to the supplier to fulfill.

The moment there is a PunchOut integration with the buyer's e-procurement application, a purchase would look like this:
Punchout catalog purchase

Purchase with a punchout catalog integraiton  


  • The prospective buyer (client’s employee) uses the e-procurement application and selects your supplier’s name as the vendor.
  • The vendor website and its contents would be fully displayed to the user even though they haven't logged in or visited the actual website. The user can now browse and search for the products or goods and add them to the shopping cart; however, instead of checking out, they punch out.
  • When the user finishes the product selection, a request is sent for approval within the user’s company's e-procurement application. The moment the approval is granted, the system sends the product list to the supplier's original site, and the normal procedure for online purchase begins.
  • The PunchOut process is quite straightforward and helps the buyer’s organization search for and purchase products freely on numerous sites without leaving their e-procurement applications.

What Format Are PunchOut Catalogs?

PunchOut catalogs work on the principle of open catalog interface (OCI), a standard format used by SAP Supplier Relationship Management, Microsoft Dynamics AX, and other purchasing systems that links to an external PunchOut online catalog.

What Is the PunchOut e-Procurement System?

Electronic procurement is a standardized way that large organizations and government agencies purchase many items for their daily needs. Although the process may seem similar to regular buying from shopping sites, there is a big difference—electronic procurement requires an e-procurement application to monitor management policies, vendor agreements, and other specifications.

An e-procurement system is a specialized application that business organizations use to conduct electronic transactions. It is a software tool through which employees of an organization or an agency purchase goods needed by that organization from a supplier.

Businesses ask their employees to conduct transactions only through their e-procurement system. The application can also be used to browse and look for products online from different suppliers. When the procurement officer sees an item that needs to be purchased, this user adds it to the cart and sends it to the buying organization for approval via the e-procurement system. Once approved, an order request is sent to the supplier.

Organizations are establishing procedures for their purchasing employees to conduct transactions only through their e-procurement system. An e-procurement software application can also be used to browse and search online for items from various vendors.
Punchout e-procurement Scheme

Punchout eProcurement Scheme


After approval from the finance department or a senior manager, the purchase order is sent to the supplier for fulfillment. Often, the approval process in organizations is built accordingly to order amount limits—small orders can be approved automatically, larger orders require approval from the purchasing manager, and especially large ones from the CFO.

There are several kinds of vendor catalogs for e-procurement systems:

Hosted catalogs

A hosted catalog is a list of products available for purchase and created by the vendor (usually in an excel format) to give vital information for searching for offered goods and services. Suppliers can easily create such kinds of catalogs, and buyers easily access them; this type of catalog is ideal for catalog lists that rarely change. However, it is unable to share information with the e-commerce website.

CIF catalogs

The Common Interchange Format (CIF) is a worldwide standard for catalog descriptions. Thousands of procurement systems from many manufacturers around the world use it. CIF catalogs are divided into two categories: full-line and cross-tabular.

  • Full-line catalogs are the most common type. They list all items in the catalog and their descriptions and prices.
  • Crosstab catalogs only list items that have been updated since the last time the file was generated. They don't include descriptions or prices.

Which type of CIF catalog you use will depend on your needs. Crosstab might be a better option if you need to update your catalog frequently. But a full line is probably better if you want to include more information about each item.

PunchOut catalog

PunchOut and CIF/Hosted catalogs both allow suppliers and organizations to display their products for sale through an e-procurement application. However, the approach toward fulfilling this goal differs.

A CIF (catalog interchange format) catalog is a static list that only provides information about goods displayed within the organization's procurement system; it is also referred to as a line-item catalog. The supplier must always compile the data for this type of catalog and upload it to the buyer's e-procurement system. Examples include SAP Ariba, Coupa, and JAGGAER.

A PunchOut catalog is a more dynamic tool that can integrate with a buyer's e-procurement system in real time and handles data automatically. The trend is that organizations use this format more frequently.

Why Do You Need to Use a Punchout Catalog?

Most companies and institutions have strict purchasing policies, budgets to follow, regulations for adding new vendors to the pool of verified vendors, and many other rules. PunchOut apps help these organizations manage procurement activities and provide several benefits, such as:

  • Reduced costs: A PunchOut system offers some opportunities to save money by reducing labor costs, mostly using automation. There are also discounts from vendors on their e-commerce sites. Working with a PunchOut system is a cost-effective process.
  • Productivity: A PunchOut catalog provides a stable online connection between an organization's e-procurement application and the supplier's website. This means the buyer won't waste time searching vendor websites when they want to purchase items for the organization, and less time will be spent placing orders because the process is automated.
  • Reduce errors and increase speed and accuracy: A PunchOut catalog helps reduce purchasing errors in the buying organization. It also makes purchasing fast because of working with a verified supplier. Procurement processes become easier to manage.
  • Centralized docflow: Companies can better manage information and purchasing with a single PunchOut catalog because the customer must send the product through the e-procurement application for approval. Companies can set the appropriate internal docflow rules, automate them, and manage the process.
  • Real-time updates: Product information and prices in PunchOut catalogs are always automatically updated on the supplier side so that information is available to customers in real time.
  • Preventing Unauthorized Purchases: Unauthorized purchases are items purchased by employees that are not on the approved purchasing list. If items were purchased with company money and in the company's name, it could cause losses. Having a PunchOut system in place means that all transaction reports are sent back to the company through the e-procurement app so dark purchases can be checked and prevented.
  • Verified Supplier Pool: It can be difficult to keep track of all the suppliers a company deals with and the products they supply. However, with the PunchOut system, a buyer can easily search for products from various sources without leaving the e-procurement application.

Although Punch Out procurement methods may seem complex and troublesome initially, they are essential for efficiency in large companies and government agencies with rigid procurement rules and multi-step internal docflow.

PunchOut Catalog Benefits

For several reasons, many B2B clients opt for the B2B punchout catalog, and product vendors have been asked to provide these catalogs. Most suppliers don't understand the reason for this and might not be quick to adapt, but experienced suppliers know how important a catalog is and the benefits it gives their customers. Benefits of using a punchout catalog include:

cXml and OCI Document Languages for PunchOut

cXML (Commerce eXtensible Markup Language) is a standard document language that gives B2B users with procurement systems the ability to PunchOut to a vendor's e-commerce website.

OCI (Open Catalog Interface) is similar to XML; however, it uses field mapping to connect the buyer's procurement system and the supplier's e-commerce site. OCI document language is more configurable than CXML and is more versatile.

This integration enables businesses to automate their ordering process, reducing the need for manual data entry.

What is a dropout item?

This is an item that was originally seen within the buyer's e-procurement application that is connected to the supplier site. When the buyer decides to buy the product, a request is sent through the procurement system for approval. When approved, the buyer initiates an order and often continues to the supplier site for final purchase.

Would we need separate PunchOut catalogs for direct B2C, B2B, and B2G?

No, when you have a PunchOut catalog, there is no need to create a separate PunchOut for direct B2C and B2B because the technology synchronizes the data moving to and from the ecommerce application.

  • Cloud-based e-procurement: this is a service that integrates with most systems, is able to get data from e-commerce platforms and other sources, and is the most versatile of integrations.

What is a CIF (Catalog interchange format) File?

A CIF file is not entirely a PunchOut but is a common data format used in the PunchOut process. It represents product data uploaded into a buyer’s e-procurement system. Unlike regular PunchOut, it has to be operated manually. 

What is level 2 PunchOut?

A level 2 PunchOut catalog gives purchasing organizations a way of searching for products to purchase within their e-procurement application without having to go to the supplier's website directly. The buyer searches for an item in their own application. If there is a level two catalog within the application, the product in the supplier's PunchOut catalog site matching the search result would be displayed. If the buyer wants to place the final order for the product, the application will redirect the buyer to that product page on the supplier's site. A level two PunchOut gives the suppliers increased visibility and visits to their catalog.

Who is the preferred PunchOut vendor for integration with the Virto Commerce online marketplace and ecommerce platform?

Virto Commerce cooperates with the TradeCentric team to deliver this integrated solution to the customer.
