The B2B e-commerce market reached $2.3 trillion in 2024 and is growing 10% annually. That's more than 10 times the size of B2C retail. But most online stores ignore this entire market segment because they don't understand how B2B buying works. B2B e-commerce is not just a smaller version of B2C selling. It's a fundamentally different sales channel with its own customer expectations, payment structures, and operational demands.
If you're selling to other businesses like wholesale products, services, or specialized goods, you need a different approach than what works for direct consumer sales. This guide covers what B2B e-commerce is, how business buyers expect to purchase online, and how to build an e-commerce store that actually converts B2B customers into repeat clients.
What is B2B e-commerce?
B2B e-commerce (business-to-business electronic commerce) is when one business sells products or services to another business through an online platform. The buyer is not a consumer making a personal purchase. It's a company buying inventory, supplies, components, or services for their own operations or resale.
The key difference: B2B buyers are making professional purchasing decisions on behalf of their organization. They want volume discounts, flexible payment terms, account-specific pricing, fast shipping, and integrations with their existing business systems. They also expect detailed product information, technical specifications, and the ability to place large orders consistently.
B2B e-commerce is distinct from wholesale, though people often use the terms interchangeably. Wholesale typically refers to selling in bulk to retailers who resell the products. B2B e-commerce is broader. It covers any online sale from one business to another, whether that's bulk product sales, recurring supplies, component manufacturing, or specialized services.
Why B2B e-commerce matters for your business
B2B selling offers several advantages over consumer retail. Business customers typically buy larger quantities, place orders more frequently, and have longer average customer lifespans. They're less price-sensitive than consumers (because they're budgeting for business needs, not personal shopping). They also tend to be more loyal. Once a B2B customer trusts your supply chain, they stick with you because switching vendors is disruptive to their operations.
The barrier to entry is lower than many entrepreneurs think. You don't need massive inventory or a household brand name. B2B customers find suppliers through search engines, industry directories, and word-of-mouth recommendations from other businesses. A well-optimized online store that answers their specific questions and makes buying easy can reach them directly.
For brands that already sell B2C, B2B can open a new revenue stream without requiring a different product. You sell the same items to retailers and other businesses at wholesale prices, alongside direct consumer sales.
How B2B e-commerce works
B2B buying follows a different process than consumer shopping. Understanding this process shapes every decision you make about your platform.
Account-based ordering and pricing
Most B2B e-commerce platforms are account-based. A buyer creates a business account, and their pricing, payment terms, and available inventory are customized to that account. Two different customers might see different prices for the same product based on volume agreements, contract terms, or payment history.
Consumers expect to see the same price as everyone else. B2B buyers expect the opposite. They expect their price to reflect their relationship and order size.
Volume-based pricing and tiered discounts
B2B buyers purchase in quantity. Your pricing structure should reward larger orders with better per-unit costs. A tiered pricing model (also called volume discounts) is standard: 10-49 units get one price, 50-99 units get a lower price, 100+ units get a steeper discount.
This requires different product data than B2C stores. You need to track minimum order quantities (MOQs), bulk pricing tiers, and cost-per-unit calculations, not just single-unit retail prices.
Extended payment terms
B2C customers pay immediately at checkout. B2B customers often expect net-30, net-60, or net-90 terms — meaning they don't pay until 30, 60, or 90 days after delivery. This is standard practice in most industries.
Your e-commerce platform needs to support invoicing, credit terms, and possibly payment plans. Many B2B e-commerce sites integrate with accounting systems like QuickBooks to automate invoicing and payment tracking.
Detailed product information and specifications
B2B buyers are making informed professional decisions. They need technical specifications, material data, certifications, regulatory compliance information, and detailed product photos or samples. They also want to download spec sheets, safety data, or compliance documentation directly from your product pages.
A B2C product page that says "beautiful blue widget" is not enough. B2B buyers want exact dimensions, tolerances, material composition, certifications, and compatibility information.
Request for quote (RFQ) workflows
Many B2B buyers don't want a fixed-price e-commerce experience. They want to submit a detailed request, and then your sales team responds with a custom quote that reflects their specific needs, volume, and timeline. Your e-commerce platform should support RFQ submission, internal review workflows, and the ability to send quotes back to the buyer.
This hybrid approach is standard in B2B e-commerce. You combine self-service catalog browsing with human sales support for custom requests.
Types of B2B e-commerce models
B2B selling online takes several forms depending on your business and industry.
Wholesale marketplace
You maintain a catalog of products available at wholesale prices. Buyers browse, select items, and place orders directly. Pricing is pre-set based on volume tiers. This is the most automated model and works well for standardized products with stable demand.
Catalog with RFQ option
You publish a product catalog, but buyers can also submit custom quote requests. For standard bulk orders, they use the catalog. For large or customized orders, they request a quote and your sales team provides a personalized price and terms.
Subscription or recurring supply
Instead of one-off purchases, B2B customers order on a recurring schedule (weekly, monthly, quarterly). They might set up auto-replenishment so supplies arrive on a predictable schedule. This creates predictable revenue and reduces the cost of repeated sales cycles.
Custom or made-to-order B2B
If you sell customized, bespoke, or made-to-order products, your e-commerce platform needs to capture specifications during the ordering process and integrate with your manufacturing or fulfillment workflow. This is common in components, packaging, and specialized manufacturing.
Who uses B2B e-commerce
B2B online selling works across nearly every industry. Manufacturers sell components to other manufacturers. Wholesalers sell in bulk to retailers. Distributors sell supplies and equipment to service businesses. Software companies sell to other businesses. Marketing agencies offer services to brands. Raw material suppliers sell to production facilities.
If you're selling something that another business needs to run its operations or resell, you have a B2B opportunity. The most successful B2B e-commerce stores target a specific industry or business type, not everyone.
Common challenges in B2B e-commerce and how to address them
B2B selling introduces operational complexity that B2C stores don't face.
Long sales cycles and multiple decision-makers
A consumer buys on impulse. A business goes through a formal procurement process with multiple people involved. The end user who needs the product, the manager who approves the purchase, the finance person who cuts the check, and the procurement specialist who handles the contract all have a say.
Your e-commerce platform can speed this up by making it easy to share product information, get approvals, and submit orders. But you also need patience — you might create an excellent online experience and still wait 60 days for a decision.
Custom pricing and complex inventory management
Your B2B customers may have different inventory levels, pricing agreements, and order minimums. Managing this requires either manual account management or advanced e-commerce software that supports tiered pricing, customer-specific catalogs, and automated order workflows.
Payment and credit risk
When you extend payment terms to B2B customers, you're extending credit. A customer who doesn't pay disrupts your cash flow. You need clear credit policies, payment terms in your contracts, and sometimes credit checks or references before you extend terms to new accounts.
Technical integration requirements
B2B customers often want to integrate their buying directly into their systems. They might want API access to your inventory, automated order placement, or integration with their ERP (enterprise resource planning) system. This requires technical capability beyond what basic e-commerce platforms offer.
How to get started with B2B e-commerce
If you're considering B2B selling, start with these foundational steps.
Define your target B2B customer
Who exactly are you selling to? A specific industry? A company size? A geographic region? The more specific you are, the better you can tailor your messaging, pricing, and operations to their needs.
Develop your pricing strategy
Calculate your wholesale pricing, volume discounts, and payment terms. Model out your margins — wholesale pricing is lower per unit, but B2B customers buy larger quantities. Work backward from your costs to determine what volume you need to make the business viable.
Choose the right e-commerce platform
Most basic e-commerce platforms are built for B2C. For B2B, you need features like tiered pricing, account-based ordering, quote management, and integration capabilities. Platforms like choosing the right e-commerce platform can vary widely in B2B capability.
Set up detailed product information
Create product pages that include everything a business buyer needs: specifications, technical data, certifications, compliance information, MOQs, and downloadable resources. Take high-quality product photos and provide detailed descriptions.
Build your B2B marketing strategy
B2B customers find suppliers differently than consumers. They use search engines to find suppliers, but they also rely on industry directories, trade shows, professional networks, and peer recommendations. Building an SEO strategy tailored to B2B keywords is critical. B2B content should answer business-specific questions, not consumer-level questions.
Create a support and sales infrastructure
B2B customers need support. They have questions about pricing for large orders, custom options, payment terms, and delivery timelines. You might need dedicated account managers or a sales team, not just an automated store.

Frequently asked questions
What's the difference between B2B and wholesale?
Wholesale typically refers to selling bulk quantities to retailers who resell the products. B2B e-commerce is broader and covers any business-to-business sale online — it includes wholesale, but also includes selling components to manufacturers, supplies to service businesses, or services to other companies. The terms are often used interchangeably, but B2B is the larger category. With WEMASY's website builder, you can set this up directly on your store.
Can I sell both B2B and B2C from the same e-commerce store?
Yes, many brands do. You can have a consumer store for direct retail and a B2B catalog for wholesale or bulk buyers. They might live on the same platform with different pricing, account types, and ordering workflows, or they might be separate storefronts. The right setup depends on your product, inventory, and customer management needs.
Do B2B customers always expect payment terms?
No, but most do when they're placing large orders. Small B2B purchases (under a few hundred dollars) often expect immediate payment like B2C. Larger orders or contracts typically include extended payment terms (net-30, net-60, net-90). The larger the order, the more likely the customer expects terms. Always clarify your payment policy upfront, and be prepared to negotiate for larger accounts.
What's a minimum order quantity (MOQ)?
A minimum order quantity is the smallest amount a buyer must purchase in a single order. If your MOQ is 50 units, a customer can't buy just 10 — they have to commit to at least 50. MOQs help wholesalers manage inventory efficiently. Lower MOQs make your products more accessible to smaller businesses; higher MOQs reduce your order processing workload but limit your customer base.
How do I find B2B customers?
B2B customers find suppliers through search (so SEO is critical), industry directories and databases, trade publications, trade shows and industry events, LinkedIn and professional networks, and referrals from existing customers. Focus first on showing up in search for your target industry keywords, then expand to industry-specific networking and directories.
How do I calculate my B2B pricing?
Start with your per-unit cost and work backward from your desired profit margin. A typical wholesale markup is 30-50% above cost (much lower than retail, which is often 50-100%+). Then create tiered pricing that rewards larger orders. For example, if your cost is $10 per unit: 10-49 units at $18 each, 50-99 units at $15 each, 100+ units at $12 each. Your profit shrinks per unit for large orders, but you gain volume and reduced sales effort. Learn more about pricing strategy.
