Best Shopify B2B Inventory Management Apps (2026)

Shopify is fantastic for direct-to-consumer (D2C) sales. But when you start adding wholesale, custom price lists, and Net 30 payment terms into the mix, managing your inventory out of the standard Shopify backend quickly becomes a nightmare.

You need a system that can handle the complexities of B2B without breaking your D2C sync. If you are looking for the best Shopify B2B inventory management platform in 2026, this guide covers the top contenders, what they do best, and how to choose the right one for your growing wholesale business.

Why Shopify B2B Needs Specialized Inventory Management

When a business scales into B2B wholesale, the inventory requirements shift drastically. D2C involves shipping single units to hundreds of customers. B2B involves shipping hundreds of units to a few key accounts, often with split shipments, backorders, and staggered payment terms.

Here are the features you absolutely must look for when evaluating B2B inventory apps for Shopify:

1. Multiple Price Lists: Your VIP distributors don't pay the same price as your tier-3 retailers. You need an app that maps specific pricing to specific B2B customers.
2. Backorders & Split Shipments: Wholesale orders rarely ship 100% complete. You need to invoice what shipped and track what is owed.
3. Purchase Order Workflows: You need to easily create POs based on low stock alerts and incoming B2B demand.
4. Sales Rep Commissions: If you have sales reps in the field, tracking their commissions per order is crucial.

Top 4 Shopify B2B Inventory Management Solutions

Let’s look at the best inventory management tools for Shopify brands doing B2B in 2026.

1. VNDLY (Best for Growing Wholesale Brands)

VNDLY was built specifically because I was frustrated with the available tools when running my own product company. It sits perfectly between "too simple for B2B" and "too complex and expensive."

It connects directly to Shopify, allowing you to manage multiple B2B price lists, handle multi-currency orders, and manage both D2C and B2B stock from one central dashboard. With built-in sales agent commission tracking and stock projection charts, it’s designed for brands that are serious about scaling wholesale.

• Pricing: Starts at $49/mo
• Best for: SMBs, brands scaling B2B alongside D2C, multi-currency wholesale
• Key Features: Unlimited price lists, stock projections, landed cost tracking, multi-location, Shopify sync.

2. Cin7 Core (Best for Heavy Manufacturing)

Formerly Dear Systems, Cin7 Core is a powerhouse if you manufacture your own goods and sell them B2B via Shopify. It has incredibly deep Bill of Materials (BOM) routing and production tracking.

However, Cin7 Core has a steep learning curve and high setup costs. It is often overkill if you simply buy finished goods from suppliers and sell them to retailers.

• Pricing: Starts around $349/mo
• Best for: Light manufacturing, assembly, complex BOMs.

3. Katana MRP (Best for Maker Brands)

Katana is another great option if you make products in-house. It’s highly visual and focuses heavily on the production schedule. If your Shopify B2B orders are custom-made or require assembly before shipping, Katana gives you a great overview of the shop floor.

The downside? Their purchasing and complex multi-currency B2B pricing features aren't as strong as their manufacturing tools.

• Pricing: Starts at $179/mo
• Best for: Custom manufacturers, artisan brands.

4. Unleashed (Best for Traditional Distributors)

Unleashed has been around a long time and is deeply embedded in the B2B distribution space. It handles multi-warehouse inventory, serial number tracking, and complex pricing tiers beautifully.

While powerful, its interface can feel slightly dated compared to modern cloud apps, and the Shopify integration, while functional, sometimes requires workarounds for complex variant structures.

• Pricing: Starts around $349/mo
• Best for: Established wholesalers, FMCG distributors.

How to Set Up Shopify B2B Inventory Management Properly

If you're integrating an inventory platform with Shopify to handle wholesale, here is the recommended setup flow to avoid syncing disasters.

Step 1: Establish the "Source of Truth"

Your inventory software (like VNDLY) must become the master record for stock levels, costs, and wholesale pricing. Shopify becomes merely a sales channel that receives stock updates.

Step 2: Handle B2B Customers

When a wholesale customer places an order, the system should recognize their specific pricing tier. If using VNDLY, you can manage unlimited price lists, ensuring that when a B2B order comes in from Shopify or is entered manually, the margins are protected.

Step 3: Manage Backorders

Wholesale orders are often massive. If a retailer orders 500 units of a SKU and you only have 300, you need to ship the 300, invoice for the 300, and keep the remaining 200 on backorder. Your inventory system must be able to split the fulfillment without confusing Shopify.
