What Sellers Are Saying
Before CrazyVendor, we were constantly sweating over our inventory numbers on Shopify and Amazon during peak holiday seasons. The sub-minute stock sync completely eliminated our overselling issues.
Sarah K.

Logging into separate accounts for eBay, Etsy, and Walmart everyday was a massive time sink. Having every single order land in one centralized dashboard has cut our daily administrative work in half.
David L.
Head of Logistics
We managed to expand our business to WooCommerce and Walmart within the same month without adding a single extra employee. CrazyVendor handles the backend complexity so we can just focus on sales.

Frequently Asked Questions
How long does it take for inventory to sync across channels after a sale?
Our system updates your stock levels across all connected marketplaces in sub-minute real-time. The moment a customer purchases an item on Amazon or Shopify, CrazyVendor instantly drops the available count on eBay, Walmart, and your other stores to completely prevent overselling.
Do I need any coding skills or developer accounts to connect my stores?
Not at all. CrazyVendor uses official, secure API integrations built with a user-first approach. Connecting a store like Shopify, WooCommerce, or eBay is a simple “point-and-click” process that takes just a couple of minutes, without requiring any technical or coding knowledge.
Can I connect multiple accounts from the same marketplace (e.g., two Amazon stores)?
Yes, absolutely. Our platform supports multi-region and multi-account management. You can link multiple accounts from the same marketplace (such as Amazon US and Amazon EU) or multiple separate websites, and manage all orders and stock from one unified dashboard.
How does CrazyVendor handle product variations like sizes and colors?
Our automated listing mapping handles complex variations effortlessly. The system matches your GTINs, counts per pack, and item attributes across different channels, ensuring that every specific variation-regardless of size or color-remains perfectly synced with your actual warehouse stock.
What happens to my native store notifications when an order is shipped?
Your brand experience stays 100% consistent. The moment CrazyVendor generates a shipping label and tracking number, that data is pushed back to the original sales channel (like Shopify or Wix) via API, which automatically triggers your store’s native branded shipping emails to your customer.
