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.
ShipBob
ShipBob is the leading third-party logistics provider built specifically for DTC e-commerce. Rather than managing your own warehouse, you ship inventory to ShipBob's network and it handles pick, pack, and ship for every Shopify order automatically. The Shopify integration is native: orders flow directly, tracking numbers sync back, and inventory levels update in real time across all warehouse locations. ShipBob's distributed network model means you can split inventory across multiple fulfilment centres to reduce shipping zones and therefore shipping costs for a geographically dispersed customer base. The platform works well for brands shipping between 400 and 10,000 orders per month. Below that threshold the per-order fees often exceed what a local 3PL or self-fulfilment would cost. Above it, enterprise-scale operations typically negotiate custom contracts.
