What is Sumtracker?

Sumtracker is inventory management and replenishment software for Shopify and Amazon merchants. It helps you sync stock across channels, prevent stockouts, and reorder intelligently.

You can connect all your stores to one Sumtracker account and manage their inventory from a central dashboard. Sumtracker works for single-store and multi-store brands, whether you fulfil orders yourself, use a 3PL, or sell with Amazon FBA or FBM.

Core problems we solve:

No overselling: real-time stock sync across every connected store and marketplace.
Fewer stockouts: demand forecasting and automated reorder suggestions tell you when and how much to order.
No overstocking: sales velocity and days-of-cover reporting show slow movers before cash gets tied up in dead stock.

Who is Sumtracker for?

Sumtracker is built for direct-to-consumer (D2C) brands selling on Shopify, Shopify Plus and Amazon. It suits you if you:

Sell on more than one store or marketplace and need one source of truth for inventory
Sell bundles, kits or multi-packs and need accurate component-level stock
Have outgrown spreadsheets for purchase orders, stocktakes or reorder planning
Manage stock across multiple warehouses, retail locations or 3PLs
Run both D2C and wholesale channels

Typical customers process 100 to 100,000+ orders per month. More than 70% sell only on Shopify and use Sumtracker for capabilities Shopify's native inventory doesn't offer.

Sumtracker may not be the right fit if you:

Are a pure B2B wholesaler with no D2C channel
Need a full ERP, manufacturing (MRP/BOM) planning, or batch/lot tracking with expiry dates
Sell on a single channel with fewer than 100 SKUs and no bundles (Shopify's native tools are usually enough)

Supported integrations

E-commerce platforms: Shopify, Shopify Plus, Shopify POS
Marketplaces: Amazon (FBA and FBM), Walmart, Etsy, eBay
Accounting: QuickBooks Online (Replenish plan)
Custom workflows: public REST API at developers.sumtracker.com

Replenish: everything in Manage, plus purchase orders, stock transfers, supplier management, 12-month demand forecasting, automated reorder recommendations, DOIR and sales margin reports, warehouse-level user permissions, label printing and the QuickBooks integration.

Every plan includes a 14-day free trial, free onboarding and free support. For current plans and prices, see sumtracker.com/pricing.
