Startup Idea: Inventory Management Tool for Marketplaces

Startup idea to develop a unified inventory management tool for shoe manufacturers that outputs the current stock into an uploadable template for marketplaces like Amazon, eBay, and Shopify, eliminating the need to use and program multiple tools.

Working for a shoe manufacturer. Something we don't have and doesn't exist as far as I'm aware of is a template tool for outputting our current inventory into an uploadable template for marketplaces like Amazon, eBay and Shopify. This then becomes a tedious task of programming a specific tool to create each different marketplace, and we have to use multiple tools when uploading new products across all of the sites.
