Thousands of SKUs.
One source of truth.
Marketplaces don't make this easy. Per-category templates, per-marketplace IDs, schemas that change quietly. Catalyte gives you a clean catalog and a starting-point export shaped for each one.

What you avoid.

What's next — direct seller APIs.
Amazon SP-API, eBay Trading API, and Walmart Marketplace API integrations — once we clear developer approval with each marketplace. CSV today gets you live; the direct path eliminates the upload step.
