WHAT IT IS: An n8n automation that takes one product row from a spreadsheet and lists it on Shopify, WooCommerce, and Amazon at the same time — no manual copy-pasting across platforms. WHY I BUILT IT: Because I was tired of watching people (and myself) type the same product title, price, and SKU into 3 different admin panels every single time — and always finding a typo in one of them later. HOW IT WORKS (full breakdown): → You add product details to a Google Sheet (name, price, description, SKU, stock) → The workflow validates it — no listing goes live with missing data → It uploads to Shopify, then WooCommerce, then Amazon, one after another → If any platform fails, it waits 30 seconds and retries — up to 5 times → You get an email either way: "all 3 live ✅" or exactly which platform broke and why THE RESULT: One spreadsheet row → three live listings. No manual re-entry, no mismatched prices across stores. Want me to build something like this for YOUR store? DM me — I'm taking on a few projects this month. What should I build next?
