B2B sellers face a fundamental question: should they invest in their own e-commerce websites or optimize their presence in customer e-procurement systems? E-commerce offers branding, personalization, and real-time data. E-procurement offers spend management, compliance, and access to corporate purchasing budgets. Both channels are growing, but resources are limited.
Understanding the landscape
B2B e-commerce represents approximately $1.4 to $1.5 trillion in volume. E-procurement accounts for roughly $700 billion and is growing at 18% year-over-year. For large organizations with procurement offices, e-procurement systems manage spending, analyze purchasing patterns, and enforce compliance with preferred suppliers who have negotiated pricing.
The challenge for sellers is that e-procurement systems can limit options, present clunky interfaces, and reduce opportunities to stand out. Meanwhile, e-commerce platforms are adding procurement-like features: approval workflows, contract pricing, and spend management tools. The lines are blurring.
The debate format
Team E-Commerce featured Sean Foran from Grainger and Rebecca Hicks from Pella Corporation. Team E-Procurement included Tim Doyle from Staples Business Advantage and Brady Behrman from TradeCentric. All brought experience navigating the tradeoffs between these channels.
Round 1: Where to invest
Sean Foran made the case for e-commerce investment. Hosted catalog files in e-procurement systems contain stale data between refreshes. Prices change, products get discontinued, and inventory levels shift without buyers knowing. During the pandemic, suppliers could not message limited PPE availability to procurement system users. The result was more customer service calls, credits, and rebuilds.
I have yet to see an e-procurement vendor that even remotely comes close to what a supplier’s core website can serve up. Even if you are a preferred supplier, you do not have firsthand knowledge how your product data is being presented, merchandised, or filtered to buyers.

Rebecca Hicks added that Pella chose e-commerce for its configurability. As a company selling configured products rather than stock SKUs, they needed to own the experience and build one-to-one configurations. E-procurement systems lacked that flexibility.
Brady Behrman countered that nobody should be in the hosted catalog business. Static data files cause downstream problems. However, e-procurement is not just about orders. It spans requisitioning, approvals, invoicing, and sourcing. Modern punchout capabilities let suppliers serve e-procurement customers through their actual e-commerce sites.
Tim Doyle explained the buyer perspective. At Staples, using the procurement system means visibility to preferred suppliers, pre-negotiated pricing, and a streamlined process. The closed-loop integration back to invoicing makes purchasing simple. For the company writing the check, standardization and compliance have real value.
When I need to buy something, I go into Coupa and I have visibility to our preferred suppliers. I see the products and vendors that we have pre-negotiated with, leveraging our buying power across the enterprise. It is a simple, easy process to get the right products at the right price.

The audience voted that B2B sellers should invest more in e-commerce sites.
Round 2: Organizational structure
Tim Doyle argued for e-procurement as a freestanding function. It requires different skill sets, different technology, and a different business model. At Staples, e-procurement reports to the CFO while e-commerce reports to the CTO. Brady Behrman reinforced that e-procurement has been underfunded and underpotentialized. It needs its own strategy, roadmap, and strong leadership.
Sean Foran disagreed. Having e-procurement as part of the e-commerce organization ensures that punchout sites mirror the main website. As the website gets new features, the punchout experience improves automatically. Shared technical resources mean better outcomes. With rapid technology changes, from EDI to XML to APIs, integration matters.
Brady Behrman clarified an important distinction: punchout should not look like the website. It should be the website. Creating separate environments wastes the investment in e-commerce functionality. However, Sean noted that even punchout loses personalization features like order history, saved lists, and user recognition that e-commerce delivers.
The moderators debated whether integration creates attribution conflicts between teams fighting for credit for the same sale. The research may happen on the e-commerce site while the purchase flows through e-procurement.
The audience voted 82% that e-procurement should be integrated with e-commerce rather than kept separate.
Round 3: Migrating offline customers
Sean Foran acknowledged that offline customers are not a dying breed. Grainger wants to serve customers however they choose: website, branch, phone, or procurement system. But online ordering provides real-time pricing, availability, personalization, and account administration that offline channels cannot match. The data from e-commerce interactions helps serve customers better.
One challenge: many e-procurement users do not have access to punchout or procurement portals. Licensing costs limit who can use the system. The people who use products are often in a paper-based world, with purchasing agents as the first ones punching out.
Rebecca Hicks noted that contractors and professionals are also B2C customers. They expect mobile, fast, transparent experiences similar to consumer shopping. Building for that expectation means online channels.
Brady Behrman suggested that meaningful customers warrant accommodation even if they prefer offline channels. But small-volume customers sending faxes or emails cost $100 to process each order. Order automation technologies can convert those orders electronically without forcing behavior change. Meanwhile, befriending procurement departments can open larger opportunities within organizations.
Tim Doyle agreed that Staples does what the customer prefers while working to convince them that digital is more efficient for everyone.
The audience voted that B2B sellers should actively migrate offline customers online.
The verdict: Both channels matter, but convergence is coming
Team E-Commerce won all three rounds. But the closing argument captured the real conclusion: it is not e-commerce versus e-procurement. It is e-commerce and e-procurement.
A decade ago, only large enterprises and government used e-procurement. Today, mid-market companies leverage these technologies. COVID accelerated digital transformation for buyers and sellers alike. Great commerce technologies serve sellers while great procurement technologies serve buyers.
E-procurement is the fastest growing channel in all of B2B. You have got to evaluate doing it all. You have got to meet the needs of your customers. The wave of the future is leveraging your commerce technology while building a cross-functional team to drive value to your customers.
Brady Behrman, TradeCentric
The practical question remains: where does the marginal dollar go? For larger organizations with enterprise customers, e-procurement investment matters. For smaller organizations, e-commerce may suffice. Companies in the middle face the toughest calls. Even Grainger must decide whether each incremental dollar enhances the website or improves e-procurement capabilities.
The channels are converging. E-commerce platforms add procurement features. Punchout capabilities improve. The answer is both, but resource constraints force prioritization. Sellers must understand their customer mix and build strategies that serve buyers however they choose to purchase.
