Sumtracker keeps stock and bundles in sync for Shopify-first brands. OneCart runs the whole marketplace workflow: stock, orders, labels, listings, prices and profit. Here is how to tell which one you need.
Sumtracker describes itself as “Inventory Management & Replenishment for Growing Shopify Brands”. That is an accurate description. It is built for brands whose Shopify store is the centre of the business, who sell the same stock on Amazon, Etsy, eBay or Walmart, and whose main problem is keeping counts and bundles right across those channels.
OneCart starts from the other end. It is built for sellers whose marketplaces are the business, and who want stock, orders, labels, listings, prices and reports in one place.
The one-line verdict: if Shopify is your hub and you only need stock and bundles in sync across a handful of channels, Sumtracker is a tidy, focused choice. If marketplaces are your main channels and your team spends the day processing orders and managing listings, OneCart does more of that work for you.

OneCart’s plans are on our pricing page: Starter $99 a month for 300 orders a month, Trader $239 for 1,000, Growth $499 billed annually for 3,500, Business $868 billed annually for 10,000. Order processing, listings, pricing and reports are included, so the comparison is a focused sync tool against an operations tool.
That is the point where sellers move from a sync tool to an operations tool.
OneCart is for brands whose marketplaces have become the main event:
Start with Shopify: connect it, map your Shopify locations, then add each marketplace and import listings. Recreate your bundles in OneCart (they can be uploaded in bulk from a file) so component stock is calculated across every channel, then switch on inventory sync. From there, orders, airway bills and listing changes all run from the same screen. Start a free trial or book a demo.
How much does Sumtracker cost? From $59 a month (or $50 billed annually) on the Manage plan for 2,500 orders a year, rising with annual order volume. Replenish starts at $119 a month.
Which channels does Sumtracker support? Shopify, Shopify Plus, Amazon FBA and FBM, Etsy, eBay and Walmart.
Does Sumtracker process orders and print labels? Sumtracker focuses on inventory, bundles and replenishment. OneCart includes order processing: pick lists, airway bills, arrange shipment and bulk mark as shipped.
Is OneCart good for Shopify brands? Yes. Many OneCart sellers use Shopify as their own store and run marketplaces alongside it from the same account, with Shopify locations mapped in OneCart.
