Supplier → Shopify
About CatalogFlow
CatalogFlow converts messy supplier spreadsheets into clean, validated, Shopify-ready product catalogs — cutting hours of manual copy-paste work and preventing failed imports.
Purpose
Give e-commerce operations teams one focused tool that takes any supplier spreadsheet and produces an import-ready Shopify product CSV — with the data quality checked before it ever reaches the store.
Problem solved
Suppliers all send different column names, missing SKUs, broken image links and inconsistent pricing. Teams rebuild these files by hand in Excel, then discover the errors only when Shopify rejects the import. CatalogFlow removes both the rekeying and the guesswork.
