With over 100 hours researching B2B ecommerce platforms, I’ve reviewed and tested dozens of sites to find which ones actually perform well for business buyers.

B2B ecommerce isn’t about flashy designs. It’s about speed, functionality, and trust.

And the best examples combine clean interfaces with enterprise-grade features like custom pricing, bulk orders, and quote requests.

My Top 5 B2B Ecommerce Website Examples for 2025:

• Grainger – Best all-round industrial B2B site
• Uline – Best for clear product navigation
• McMaster-Carr – Best product search and UX
• Amazon Business – Best for B2B features with B2C design
• Fastenal – Best for serving enterprise and SMB buyers alike

Quick Comparison Table

#1. Grainger – Best Overall B2B Ecommerce Site

Rating: 4.8/5
URL: grainger.com
Industry: Industrial Supply
Custom Pricing: Yes
Bulk Ordering: Yes

Grainger is one of the best B2B ecommerce sites in the world, especially if you’re a procurement manager or business buyer working in construction, engineering, or facilities management.

The homepage is built for speed: smart navigation, live inventory, and fast access to categories.

Why Grainger Works

✔️ Bulk ordering tools
✔️ Account-based pricing
✔️ Reorder from order history
✔️ PDF data sheets on product pages
✔️ Quick order by SKU

Drawbacks

❌ You must log in to access core features
❌ Not very visual – pure functionality

If you’re serious about B2B ecommerce UX, Grainger’s layout and backend integration set the standard. It combines ecommerce with a powerful procurement tool.

Bottom Line:
If your business needs to order in bulk, manage teams, and access net terms, Grainger delivers every essential feature.

#2. Uline – Best for Clear Product Navigation

Rating: 4.6/5
URL: uline.com
Industry: Packaging and Warehouse Supplies
Custom Pricing: Yes
Bulk Ordering: Yes

Uline’s website doesn’t win any design awards. And that’s exactly the point.

It’s a clean, no-nonsense experience built for repeat buyers who don’t need fluff—they need function.

With over 40,000 SKUs, Uline organizes everything by category so clearly that I never felt lost.

Why Uline Works

✔️ Lightning-fast category navigation
✔️ Excellent inventory detail per SKU
✔️ Real-time shipping timelines
✔️ Clear quantity pricing tiers
✔️ Old-school catalog lovers welcome

Drawbacks

❌ Minimal personalization
❌ Requires internal account approval for terms

Uline’s homepage doesn’t even try to sell you on branding. Instead, it helps you move quickly from category to checkout in just a few clicks.

Bottom Line:
Perfect if your users know what they’re ordering every month and want speed and accuracy over visuals.

#3. McMaster-Carr – Best for Search Functionality

Rating: 4.5/5
URL: mcmaster.com
Industry: Industrial Components
Custom Pricing: Not public
Bulk Ordering: Yes

McMaster-Carr’s ecommerce site hasn’t changed much in years—and it doesn’t need to. Its legendary search experience puts most B2C giants to shame.

From filters to in-page specs to lightning-quick product rendering, this site is built for engineers and purchasing agents who want precise answers, fast.

Why McMaster Works

✔️ Instant filtering and smart search
✔️ Product info loads inline—no need to click through
✔️ Excellent specification clarity
✔️ Auto-complete search suggestions
✔️ Live shipping ETAs

Drawbacks

❌ Not optimized for mobile
❌ Old-school layout (no images in nav)

You don’t need onboarding. You don’t need a chatbot. You just type what you want and it shows up—accurately.

Bottom Line:
McMaster is the king of search-based ecommerce. If you want to replicate just one thing from them, copy their UX for product search and navigation.

#4. Amazon Business – Best for Familiar UX + Enterprise Features

Rating: 4.4/5
URL: amazon.com/business
Industry: Multi-category
Custom Pricing: Yes
Bulk Ordering: Yes

Amazon Business is a hybrid of what everyone already knows—plus the backend tools large procurement teams need.

And that’s what makes it one of the most accessible and scalable B2B ecommerce platforms available today.

You can set up approval workflows, manage purchase limits, and create multi-user accounts all from a familiar interface.

Why Amazon Business Works

✔️ Familiar shopping experience
✔️ Multi-user controls
✔️ Net 30 payments
✔️ Real-time tracking and support
✔️ Tiered pricing and dynamic offers

Drawbacks

❌ Lacks deep industry-specific features
❌ Limited customization compared to niche B2B platforms

While not suitable for highly specialized industries, Amazon Business is perfect for IT, office supply, and general procurement needs.

Bottom Line:
If your buyers are already using Amazon in their personal lives, the switch to Amazon Business is frictionless.

#5. Fastenal – Best for Balancing Enterprise and SMB Buyers

Rating: 4.2/5
URL: fastenal.com
Industry: Industrial, Safety, Construction
Custom Pricing: Yes
Bulk Ordering: Yes

Fastenal’s ecommerce site does something rare: it caters to both small business buyers and large enterprise accounts without overcomplicating either side.

The UI is clean, the ordering process is straightforward, and support tools (like quotes and product data) are easy to find.

Why Fastenal Works

✔️ Quote request tools
✔️ Live inventory per location
✔️ Quick reordering from history
✔️ Split delivery options
✔️ Regional product availability

Drawbacks

❌ Less modern UX compared to others
❌ Occasional downtime during updates

Their digital catalog balances function and usability, while still integrating with backend systems like ERP, shipping, and sales reps.

Bottom Line:
A reliable example of how to scale ecommerce across customer segments without building two separate platforms.

Comparison Overview

These five websites were selected not just for their frontend usability, but also for how well they support complex B2B requirements behind the scenes.

Whether it’s offering flexible pricing structures, allowing bulk uploads, or integrating with back-office tools, each platform is built to meet the realities of business purchasing—where speed and accuracy often matter more than branding.

How I Chose These B2B Ecommerce Sites

To narrow down the best examples, I tested and evaluated ecommerce platforms based on:

• Navigation and search (speed, accuracy, filtering)
• Bulk ordering tools
• Account-based features (logins, pricing, approvals)
• Responsiveness on desktop and mobile
• Checkout process and quote handling
• ERP or CRM integration capabilities

I also looked at backend features that most buyers won’t see—like how well the site handles multiple warehouses, large product catalogs, or net terms.

Beyond feature checklists, I paid attention to how quickly I could place a mock order, how easy it was to repeat that order, and how many steps it took to access specs or inventory data.

B2B ecommerce needs to reduce friction, not add it—so the fewer clicks, the better.

Key Takeaways

• Grainger leads with functionality and enterprise UX
• Uline is best for easy category browsing
• McMaster-Carr dominates with smart search tools
• Amazon Business makes B2B feel like B2C
• Fastenal balances usability across buyer types

Each of these sites offers something valuable. Whether you’re designing your own B2B ecommerce store or optimizing an existing platform, you can pull ideas from each example.

Final Verdict: Which B2B Site Should You Use for Inspiration?

If you’re designing for manufacturers, logistics companies, or service-based B2B clients, the five examples above should be your first reference points.

Choose based on your audience:

• Complex catalogs? Look at McMaster-Carr.
• Repeat buyers with large teams? Use Grainger as a template.
• Small B2B buyers needing quick ordering? Follow Uline’s model.
• General business supplies? Amazon Business is hard to beat.
• Blended audience? Fastenal gets it right.

Use these real-world examples to help set the foundation of your ecommerce strategy—not just by copying features, but by understanding why they work.

The best B2B sites aren’t flashy; they solve real business problems.
