There isn't a single 'catalog' competitor — product data usually lives scattered across spreadsheets, a storefront, and each tool's own copy. Here's that comparison, straight.

A shared sheet of products and prices. Free, familiar — and the source of every 'why does the invoice say a different price?' the moment a second tool keeps its own copy.
Fine if the storefront is the only place you sell. But the data is trapped inside it — your agents, invoices and stock each end up with a separate, drifting copy.
An AI-native system of record — API, webhooks and MCP — that CRM, Billing, Inventory and the agents all reference by ID. Change a price once; correct everywhere.
The honest default for product data in most SMBs is a spreadsheet. It's free and everyone can edit it — which is exactly the problem once more than one system needs the truth.

If you sell on Shopify or a marketplace, your products live in its catalog. That's fine until your phone agent, your invoices and your stock system each need the same truth — and the storefront won't give it up cleanly.

Where they win, we said so. Where we win, it's because SK Catalog shares one record with the rest of your business.
