About
Inventory Planner
Inventory Planner solves the problem that kills many e-commerce brands quietly: running out of stock on bestselling products or tying up too much cash in slow-moving inventory. It connects to Shopify and your supplier data, analyses historical sales velocity by SKU and variant, applies seasonal adjustment factors, and calculates exactly how much to reorder and when, taking lead times into account. The purchase order workflow allows you to send replenishment orders directly to suppliers from within the platform. For brands managing 50 or more active SKUs across multiple suppliers with varying lead times, the manual spreadsheet approach becomes unworkable quickly and stockouts become frequent and expensive. Inventory Planner automates the calculation layer without requiring a custom ERP or data science team to run it.
Linnworks
Linnworks is built for merchants that sell across multiple channels simultaneously and need inventory levels to stay accurate everywhere in real time. When a unit sells on Amazon, Shopify stock updates immediately. When a return arrives on eBay, inventory is restocked across all channels simultaneously. The order management layer consolidates fulfilment across channels with warehouse routing, picking workflows, and multi-location stock control. For brands that exclusively sell on Shopify, Linnworks is likely over-specified and more expensive than the problem justifies. Its value scales with channel complexity: the more channels you sell on and the more warehouse locations you manage, the more the centralised control pays off. It sits above ShipStation in operational complexity and is typically used by brands past the $2M ARR mark managing real multi-channel inventory risk.
