Your wholesale customer just placed a $25,000 order for 500 units of your industrial equipment. Exciting, right? Then they ask: “What’s the freight cost to ship this to our warehouse in Phoenix?”
You stare at your WooCommerce shipping settings, which cheerfully offer “Standard Shipping: $9.99” and “Express Shipping: $19.99.” Those options suddenly feel laughably inadequate.
If you’re selling B2B, especially products that are heavy, bulky, or ordered in large quantities, your retail shipping methods aren’t going to cut it. Wholesale orders often require freight shipping, less-than-truckload (LTL) carriers, white glove delivery, or other specialized shipping methods that standard WooCommerce simply doesn’t handle.
The challenge? WooCommerce’s shipping system was designed for small packages going through UPS, FedEx, or USPS. When your orders start involving pallets, freight quotes, and delivery appointments, you need a completely different approach.
At Built Mighty, we’ve helped dozens of wholesale businesses solve this exact problem. Let’s walk through everything you need to know about B2B shipping calculations in WooCommerce.

Before we dive into solutions, let’s talk about why B2B shipping is fundamentally different from B2C shipping:
Order sizes and weights – While retail orders might be 2-5 pounds, wholesale orders can easily be 500+ pounds, requiring special handling and carriers.
Delivery requirements – Business customers often need scheduled deliveries, dock appointments, liftgate service, or inside delivery—services that standard carriers either don’t offer or charge premium rates for.
Shipping destinations – B2B shipments often go to commercial addresses, warehouses, or job sites with specific delivery requirements and restrictions.
Cost expectations – Business customers expect accurate freight quotes, not flat-rate shipping. They’re often comparing your total delivered cost against competitors.
Documentation needs – Commercial shipments may require bills of lading, freight classifications, special handling instructions, and detailed tracking information.
Let’s break down the most common B2B shipping methods and when you’d use each:
Best for: Orders under 150 lbs, non-bulky items Typical cost range: $15-150 depending on weight and distance WooCommerce compatibility: Works with standard shipping plugins
Best for: Orders 150-10,000 lbs, palletized shipments Typical cost range: $200-2,000+ depending on weight, distance, and class Key considerations: Freight class, pickup/delivery requirements, special services
Best for: Very large orders, multiple pallets to same destination Typical cost range: $1,500-5,000+ depending on distance and equipment needs Key considerations: Truck type requirements, loading/unloading responsibilities
Best for: High-value items, installation required, residential delivery Typical cost range: $300-1,500+ depending on services required Key considerations: Insurance, assembly, debris removal
Best for: Specific industries, regional coverage, specialized equipment Examples: Construction materials, hazardous materials, temperature-controlled
The key insight? Each of these shipping methods has different pricing structures, requirements, and integrations—none of which work with WooCommerce’s standard “weight × rate” shipping calculations.
WooCommerce’s shipping system has several limitations when it comes to B2B orders:
Linear pricing assumptions – WooCommerce assumes shipping costs increase linearly with weight. In freight shipping, there are often thresholds where costs jump significantly (like the difference between ground and LTL).
Limited carrier integrations – Most WooCommerce shipping plugins focus on UPS, FedEx, and USPS. Very few integrate with LTL carriers or provide freight quoting.
No freight classification – LTL shipping requires freight class determination based on density, handling, liability, and stowability—concepts that don’t exist in standard WooCommerce.
Address validation gaps – Freight carriers need to verify commercial addresses, dock availability, and delivery restrictions before providing accurate quotes.
Quote complexity – Freight quotes often include base charges, fuel surcharges, accessorial charges, and various fees that can’t be calculated with simple shipping rules.
For businesses with predictable shipping patterns, you can extend WooCommerce’s shipping zones with custom logic.
How it works: Create shipping zones based on your common delivery areas and build custom shipping calculations that account for weight thresholds, dimensional considerations, and freight class.
Pros:
Cons:
Best for: Businesses with consistent shipping patterns and limited product variety.
This approach integrates directly with freight carriers’ API systems to provide real-time shipping quotes at checkout.

Best for: High-volume wholesale operations where accurate freight costs are critical to competitiveness.
Many businesses find success with a hybrid approach that combines automated calculations with manual override capabilities.
How it works: Use automated calculations for standard scenarios, but allow staff to manually quote complex shipments and override shipping costs before order confirmation.

Cons:
Best for: Businesses with complex products, variable shipping requirements, or established customer relationships where personal service is valued.
After implementing dozens of B2B shipping solutions, here are the mistakes we see most often:
Underestimating freight classification complexity – Freight class determination is both art and science. Invest in proper training or partner with experienced freight professionals.
Ignoring accessorial charges – The base freight quote is often just the starting point. Accessorial charges can add 20-50% to the final cost.
Poor address validation – Residential delivery charges can turn a profitable order into a loss. Validate addresses and delivery requirements upfront.
Inadequate customer communication – B2B customers expect detailed shipping information, tracking, and delivery coordination. Build these into your process.
Mixing B2B and B2C shipping – Don’t try to force B2B orders through B2C shipping methods. The customer experience and cost structure are fundamentally different.
When we implement B2B shipping solutions, we focus on three key areas:
1. Understanding your products and customers Before building any technical solution, we analyze your product mix, typical order patterns, and customer delivery requirements.
2. Scalable integration architecture We build systems that can start simple but grow to handle complex multi-carrier, multi-warehouse scenarios as your business expands.
3. Operational workflow optimization The best shipping calculation is useless if your team can’t efficiently manage the orders. We design solutions that fit your operational capabilities.
B2B shipping in WooCommerce touches every aspect of your wholesale operation—from product catalog setup and freight classification to customer communication and order fulfillment. While there are some plugins that can help with basic scenarios, most wholesale businesses find that custom development provides the accuracy, integration, and scalability they need to compete effectively.
At Built Mighty, we’ve helped businesses implement everything from simple weight-based freight calculations to sophisticated multi-carrier TMS integrations. The key is choosing an approach that provides accurate pricing while fitting your operational capabilities and growth plans.
