How do you manage inventory across Amazon, your own website, and retail stores?

[longtime2]

My company sells through our own Shopify store, Amazon, and a few boutique retail partners. Our biggest headache is inventory—we're constantly overselling on one channel because stock is stuck in another, or we're paying to store the same product in three separate warehouses. How are other businesses handling true omnichannel fulfillment services from a single inventory pool? Is this something we can manage with software alone, or do we need a completely different logistics partner?

This is the core challenge of modern retail, and software alone won't solve it—you need an integrated operational solution. True omnichannel fulfillment requires a logistics partner with a unified Warehouse Management System (WMS) that can see your total inventory as a single pool and allocate it in real-time based on orders from all your channels. This means one stock holding location feeding all sales points. The right partner will have the technology to connect seamlessly to your Shopify, Amazon Seller Central, and other platforms, automatically routing orders to be picked and shipped from the same bin, whether it's going to a customer's home or to a retail store for shelf replenishment (a process called "ship-to-store"). This eliminates channel-specific silos, dramatically reduces your total storage footprint, and prevents overselling. It turns your logistics from a cost center into a strategic sales enabler. For a detailed look at how this is operationalized, I recommend this guide on omnichannel fulfillment services. It breaks down the key capabilities you should be looking for in a provider.
