Sumtracker is a multi-channel inventory management platform that focuses on keeping stock levels synchronized across Shopify, Amazon, eBay, Etsy, and Walmart in real time. When a unit sells on one channel, Sumtracker updates all connected channels instantly — preventing overselling and the customer service headaches that come with it.
Beyond sync, Sumtracker offers native bundle and kit management (where selling one product deducts component SKUs), purchase order creation, and multi-location support for stores with multiple warehouses. Their pricing starts at $49/month. While Sumtracker includes basic forecasting, it's primarily an inventory sync and operations tool — forecasting isn't its core strength. That's where it differs most from Sensible Forecasting, which is purely focused on demand forecasting and reorder timing.
