If you sell on more than one platform, you have an inventory problem. Amazon doesn't know about your eBay stock. TikTok Shop doesn't know what's in your warehouse. And your spreadsheet is always one sale behind.
The result: overselling, underselling, and hours spent reconciling numbers that should match but don't.
Lambda Inventory connects your marketplace accounts — Amazon, eBay, TikTok Shop, Walmart, and Shopify — so you can see your real inventory position in one place. When a sale happens on Amazon, it's reflected in your stock count. When you add inventory through the scanner, it's available across every connected platform.
But here's what makes this different from other multi-channel tools: Lambda Inventory tracks at the unit level. Every individual unit has a cost, a location, a status, and a history. When you sell unit #47 of a product on eBay, the system knows exactly which unit was sold, what you paid for it, and what your actual profit was on that specific sale.
Most multi-channel tools give you SKU-level stock counts. Lambda gives you unit-level traceability.
