Where things break down
The Problem
Stock mismatches across three platforms
A product sells out on Amazon. Your Shopify store still shows it in stock. A customer buys it. Now you have a problem.
The Fix
Three-way sync
One sale anywhere updates all three channels instantly. Shopify, Amazon, and eBay stay in lockstep — automatically.
The Problem
Your team has no shared source of truth
One person checks Amazon Seller Central, another watches Shopify. Nobody agrees on the actual stock count. Decisions get made on stale data.
The Fix
One shared catalog
Your whole team sees the same numbers at the same time. One table, every channel, always current.
The Problem
Your catalog doesn't fit any platform's schema
You sell products with custom attributes — materials, dimensions, variants — that Amazon and eBay can't represent the way you need. You're working around the tool instead of with it.
The Fix
Flexible catalog
Model your products exactly as they are. Custom fields, variants, hierarchies — no rigid schema forcing you into someone else's structure.
