The assumption seems reasonable: B2B e-commerce is just B2C e-commerce with business customers. Same platforms, same patterns, same best practices, just with purchase orders instead of credit cards and company names instead of individual names.
This assumption leads to failed implementations. B2B commerce looks superficially similar to B2C but differs in almost every dimension that matters. Companies that approach B2B with consumer commerce playbooks build systems their business customers can’t use, won’t adopt, and actively resent.
Understanding the differences isn’t academic. It’s the difference between B2B e-commerce that drives growth and B2B e-commerce that sits unused while customers keep calling sales reps.
The buyer isn't a person: it's an organization
B2C: One person decides, one person pays, one person receives. The buying process is contained in a single individual (or household).
B2B: Multiple people involved in a single purchase. The person researching isn’t the person approving. The person approving isn’t the person receiving. The person receiving isn’t the person paying. A single order might touch procurement, budget holder, receiving dock, and accounts payable, each with different needs and system access.
What this means for commerce:
Account structures with multiple users, roles, and permissions. Not one login per company but hierarchies of users with different capabilities.
Approval workflows. Orders above certain thresholds need approval before submission. Platforms that don’t support this force organizations back to manual processes.
Visibility appropriate to role. The procurement manager sees all orders; the requester sees only their own. The executive sees spend dashboards; the receiver sees delivery schedules.
Organizations don’t adapt to platforms that assume individual buyers. Platforms must adapt to organizational buying.
Pricing isn't listed: it's negotiated
B2C: Price on the website is the price. Everyone pays the same (with occasional promotional variations). Pricing is simple and transparent.
B2B: Every customer might have different pricing. Negotiated contracts, volume discounts, customer-specific agreements, bid pricing, cost-plus arrangements. The "list price" might be a starting point for negotiation or might be meaningless.
What this means for commerce:
Customer-specific pricing that displays only when authenticated. Anonymous browsing might show list prices (or no prices at all); logged-in customers see their negotiated rates.
Contract management. Pricing tied to agreements with start dates, end dates, volume commitments. The commerce platform needs to know about and enforce contracts.
Quote workflows. For non-standard items or large orders, the customer needs to request a quote, receive a price, and potentially negotiate before the order is placed.
Pricing rules engines. Volume breaks, tiered pricing, bundle pricing, customer-tier pricing, geography-based pricing, often all applying to the same catalog. Simple percentage markups won’t cut it.
Platforms built for transparent consumer pricing can’t handle B2B pricing complexity without significant customization, and even then, often poorly.
Payment isn't immediate: it's on terms
B2C: Customer pays at checkout. Credit card, PayPal, maybe buy-now-pay-later. Payment happens before or at the moment of fulfillment.
B2B: Customer pays on terms. Net 30, Net 60, sometimes Net 90. The order is placed, goods are delivered, an invoice is generated, and payment arrives weeks later. Credit limits, credit holds, and collection processes are all part of B2B commerce.
What this means for commerce:
Credit management integrated into ordering. Can this customer place this order given their credit limit and outstanding balance? Real-time credit checks against the ERP.
Payment method complexity. Some orders go on terms; some get paid by card (especially smaller orders or new customers). Purchase orders, blanket orders, procurement cards, ACH transfers, each with different processes.
Invoice presentation and payment. Business customers need to access invoices, pay them electronically, and reconcile against their systems. The commerce platform might need to be a payment portal as well as an ordering portal.
Order-to-cash integration. B2B commerce doesn’t end at order confirmation. It extends through invoicing, collection, and cash application. Disconnection between commerce and AR creates customer frustration and collection problems.
The catalog isn't universal: it's customer-specific
B2C: Everyone sees the same products at the same prices. The catalog is a unified presentation to all customers.
B2B: Different customers might see different products. Authorized distributors for certain brands. Qualified buyers for restricted products. Contract-specific assortments. Products not available in certain regions or for certain customer types.
What this means for commerce:
Customer-specific catalogs that control what products are visible, searchable, and orderable for each account.
Product qualification rules. This customer is approved for this product; this other customer isn’t. Professional-grade products for professional customers only.
Catalog hierarchies and customization. A manufacturer’s catalog might be presented differently to different distributor types, with different assortments and different pricing.
Platforms designed for universal catalogs require significant modification to handle customer-specific visibility, and often implement it as an awkward workaround rather than a core capability.
The order isn't simple: it's complex
B2C: A few items, standard quantities, shipping to a single address, delivery in days.
B2B: Hundreds of line items. Bulk quantities with unit-of-measure conversions. Multiple ship-to addresses on a single order. Scheduled deliveries over months. Partial shipments, backorder handling, blanket orders with releases.
What this means for commerce:
Order entry designed for efficiency at scale. Quick-order forms, spreadsheet upload, reorder from history, order templates. Nobody wants to add 200 items to cart one by one.
Unit-of-measure handling. The customer orders in cases; the system tracks in eaches; pricing is per thousand. Conversions need to be seamless.
Complex fulfillment requirements. Split shipments to multiple locations. Delivery scheduling to coordinate with production schedules or jobsite readiness. Consolidation to reduce freight costs.
B2B order complexity routinely breaks platforms designed for simple consumer orders.
The relationship isn't transactional: it's ongoing
B2C: Each purchase is relatively independent. Brand loyalty exists, but the relationship is loose. Losing one customer matters little; they’re individuals in a large pool.
B2B: Relationships are deep and long-term. The same customers order repeatedly, often through the same sales reps who manage the relationships. A single customer might represent millions in annual revenue. Losing a customer is a significant business event.
What this means for commerce:
Sales rep integration. The commerce platform can’t replace the sales relationship. It needs to support it. Reps need visibility into what their customers are doing online. Customers need easy access to their rep. Orders placed online might still be credited to the rep for commission purposes.
Assisted selling. Not pure self-service but a blend. Customers might start orders online and finish with rep assistance. Reps might place orders on behalf of customers. The platform supports both modes.
Relationship continuity. Order history, communication history, contract history, and issue history, all visible and connected. The platform should make the relationship feel continuous, not transactional.
B2C platforms treat the sale as the end. B2B platforms need to treat it as one touchpoint in an ongoing relationship.
The integration isn't optional: it's essential
B2C: The e-commerce platform can operate relatively standalone. Integration with other systems is nice to have but not always critical.
B2B: Integration is table stakes. The commerce platform must connect to ERP for pricing, inventory, and order flow. To CRM for customer and relationship data. To procurement systems (cXML, punchout) that business customers require. To EDI for large customers who won’t use a web portal.
What this means for commerce:
Real-time or near-real-time integration with back-office systems. Pricing from ERP. Inventory from WMS. Orders flowing back to ERP for fulfillment. Customer credit from AR.
Punchout catalog support. Large customers expect to browse your catalog from within their procurement system (Ariba, Coupa, SAP) and have the cart pass back seamlessly. This isn’t optional for enterprise customers. It’s required.
EDI capability. Some customers will never use a web portal. They send EDI 850s and expect EDI 855s and 810s in return. The commerce platform needs to handle both web and EDI channels.
B2B commerce without integration isn’t e-commerce. It’s just a website.
The right approach
B2B commerce requires platforms and approaches purpose-built for business buying. This might mean:
B2B-specific platforms. Solutions like BigCommerce B2B, Adobe Commerce (Magento) with B2B extensions, Salesforce B2B Commerce, or specialized platforms like Sana or OroCommerce that were designed for business buying.
Significant customization of flexible platforms. Taking a platform with strong B2B bones and building out the specific capabilities your business requires.
Composite approaches. Using best-of-breed components for different B2B needs: a CPQ system for pricing complexity, a dedicated customer portal for service functions, an order management hub that connects them.
What doesn’t work: Taking a consumer commerce platform and expecting business customers to adapt to consumer patterns. They won’t, and you’ll spend years building workarounds for capabilities that should have been native.
