Connects to Your Entire Stack. Replaces Half of It.

SkuNexus integrates natively with major ecommerce platforms (Shopify, Magento, BigCommerce, Shopware, WooCommerce), marketplaces (Amazon FBA, Amazon FBM, eBay, Walmart), ERP and accounting systems (QuickBooks, Sage 100), and shipping carriers (UPS, FedEx, USPS, DHL). It also supports EDI for B2B wholesale channels and provides an open REST API for custom integrations with any system that has an API endpoint.

The goal is to replace the disconnected tools you're currently using to bridge gaps between platforms. Many merchants run a channel sync tool, a separate inventory tool, a WMS, a shipping platform, and accounting software - all partially integrated with each other through middleware. SkuNexus replaces the middle layers by natively connecting to your sales channels, carriers, and accounting system while handling inventory, orders, warehouse operations, and shipping internally. Fewer tools means fewer sync failures, fewer reconciliation headaches, and lower total software spend.

Ecommerce integrations use bidirectional API connections that sync three types of data. First, inventory levels: when stock changes in SkuNexus (from a sale, adjustment, receiving event, or return), updated available quantities push to every connected store and marketplace. Second, orders: when a customer places an order on any channel, it downloads into SkuNexus within seconds with full context (items, customer address, shipping method, channel source). Third, tracking: when an order ships, the tracking number and carrier push back to the sales channel so the customer sees their shipment status.

The quality of these integrations varies wildly across platforms. Some route through third-party middleware that adds sync lag and another potential point of failure. Others only sync inventory in one direction, or sync orders but not tracking. SkuNexus maintains native, direct API integrations that don't rely on middleware - so inventory, orders, and tracking flow directly between SkuNexus and each connected platform with minimal latency.

Yes, with no artificial limits. Unlike some platforms that restrict you to one Shopify store per account or one Amazon marketplace per connection, SkuNexus connects to unlimited stores, marketplaces, and accounts from a single instance. All channels draw from the same unified inventory pool, and all orders flow into the same queue for processing through the Auto-Decision Engine.

This is increasingly important as merchants grow. A brand might run separate Shopify stores for DTC, wholesale, and international markets, plus sell on Amazon US and Amazon Canada, plus list on eBay and Walmart. Each of these channels needs accurate, real-time inventory data from the same pool. One merchant described a previous platform that could only connect to one Shopify store per account - forcing separate inventory management for each store, which defeated the purpose of having a centralized system.

In most cases, yes. Channel-specific middleware exists because your OMS can't talk directly to your sales channels, or can't handle the inventory sync, order routing, and fulfillment orchestration needed across multiple platforms. When your OMS natively integrates with every channel and handles all of this internally, the middleware layer becomes redundant - and expensive.

One prospect was paying $3,400 per month for a channel management tool that provided no WMS, no shipping, and no order routing - just inventory sync across channels. That's over $40,000 per year for functionality that should be built into your operations platform. SkuNexus handles multi-channel inventory sync, order aggregation, fulfillment routing, warehouse management, and shipping from one platform. The channel management middleware, the separate WMS, and the standalone shipping tool get replaced by a single system that does all three.

SkuNexus syncs operational data to your accounting system so financial records stay accurate without manual journal entries or duplicate data entry. Purchase orders, receiving events, COGS calculations, inventory valuation, and sales data flow from SkuNexus to QuickBooks, Sage 100, or other accounting platforms automatically. When a PO is received in the warehouse, inventory asset values update in accounting. When an order ships, the sale records.

The alternative is manual reconciliation: the warehouse receives inventory in the WMS, then someone logs into the accounting system and enters the same data again. This creates lag between operational reality and financial records, introduces transcription errors, and means your books are always slightly behind what's actually happening. For QuickBooks and Sage 100, SkuNexus provides native integrations. For other ERPs, the open REST API enables custom data flows between systems.

EDI (Electronic Data Interchange) is a standardized format for exchanging business documents - purchase orders, invoices, advance ship notices, and inventory updates - between trading partners electronically. You need EDI when selling to major retailers (Walmart, Target, department stores) or working with large B2B customers who require it as a condition of doing business. These partners won't accept orders via email or CSV upload; they require EDI-formatted transactions.

Many ecommerce merchants start as DTC-only and add wholesale channels as they grow. The first time a major retailer requires EDI compliance as a condition of partnership, merchants realize their operations platform either supports it or they need yet another specialized tool. SkuNexus supports EDI integration for merchants who sell wholesale alongside their DTC channels, so B2B document exchange works within the same platform that manages your DTC orders and warehouse operations.

API-first means every function in the platform is accessible through a documented REST API - not just a few endpoints the vendor chose to expose. If you can do it in the web interface, you can do it programmatically through the API. This matters because your business will eventually need an integration, automation, or workflow that the vendor didn't plan for, and the API is how you build it.

With a closed or limited API, you're dependent on the vendor to build every integration and feature you need. When they say no or deprioritize it, you're stuck. With an API-first platform, your developers build what you need without waiting. Examples include custom reporting dashboards that pull operational data, automated workflows that trigger actions in other systems when events occur in SkuNexus, and integrations with niche tools specific to your industry. SkuNexus is fully API-accessible with documentation, so your team maintains control over your tech stack's capabilities.
