Connecting your store
Fulfillment clientsShopify connects through the Kaerwell app; WooCommerce, BigCommerce, Squarespace, Wix, Magento, Amazon, Walmart, eBay, Etsy, and more than 100 other platforms connect through our integration team. Once connected, orders import automatically and tracking and inventory flow back.
Shopify
Shopify connects through the Kaerwell app, Kaerwell Connect. Once your fulfillment account is set up, you have a login for it. The app's setup takes your store through six steps: connect your Kaerwell account, confirm your inventory location, map your catalog, map your shipping methods, request approval with your go-live date, and go live. Orders import as they are placed and tracking posts back when they ship.
Other platforms
Your specialist connects them during onboarding and walks you through each step.
Three things to set before orders flow
- SKUs match. Every product in your store must carry the same SKU as the product in the fulfillment portal. A mismatch lands the order in API errors; see API errors: why an order did not import.
- Shipping methods are mapped. Each shipping option in your store (free shipping, flat rate, 2-day) is mapped to a carrier service. Unmapped methods stop the order.
- Products we do not ship are marked virtual. Digital products, consultations, or items you ship yourself are set as virtual SKUs so they do not block the order.
Inventory sync
Stock levels sync from the portal to your store so you never oversell. Syncs run during the day and overnight; a manual resync takes about 20 minutes. Tell us if a count looks wrong.
Several stores
Connect as many as you like; orders from each carry a suffix so order numbers never collide.
