About Sumtracker

Sumtracker is inventory management and replenishment software for Shopify and Amazon merchants, from single-store brands to multi-channel sellers. The platform solves three problems: overselling across channels, stockouts on bestsellers, and overstocking on slow movers. It powers over 2,000 direct-to-consumer brands across 50+ countries, with customers concentrated in the United States, Canada, the United Kingdom, Australia, and Europe. Sumtracker gives e-commerce brands a single source of truth for their inventory across every store, marketplace, warehouse, and 3PL. It replaces manual stock reconciliation across channels, frees up working capital tied up in dead stock, and helps merchants make data-driven purchasing decisions. Core capabilities include real-time multi-channel inventory sync, bundle and kit management with component-level tracking, purchase order automation with multi-supplier and multi-currency support, demand forecasting based on historical sales and seasonality, automated replenishment recommendations, stock transfers, stocktakes with barcode scanning, landed cost tracking, and detailed inventory audit trails. Sumtracker integrates natively with Shopify, Shopify Plus, Shopify POS, Amazon (FBA and FBM), Walmart, Etsy, eBay, and QuickBooks, and offers a public REST API for custom integrations. More than 70% of Sumtracker's customers sell exclusively on Shopify - often across multiple stores — using the platform to get inventory capabilities that Shopify's native tools lack. The remaining customers use Sumtracker for full multi-channel operations across marketplaces. Sumtracker is featured in Shopify's 2026 guide to the best inventory management software for small business, and holds a 4.8/5 rating on the Shopify App Store with 115+ reviews. Publicly named customers include EasyPlant, Beauty Heroes, Mister Zimi, Bamboo Body, and Whif. Sumtracker was founded in December 2020 by Ankit Goyal and Kush Goyal, and is bootstrapped and profitable.
