Getting started

Install the app, paste your bol or Kaufland keys, review what the setup agent found and go live.

bol & Kaufland Sync keeps bol.com and Kaufland in step with your Shopify store: stock goes out, orders come in, tracking goes back. A setup agent does the first pass and shows you everything before it changes anything.

Before you start

A bol seller account or a Kaufland Seller Portal account, with offers you already sell.
EANs on your Shopify variants (the barcode field). Both marketplaces match products by EAN; SKUs work as a fallback.
Know which Shopify location ships marketplace orders.

Set up

Install bol & Kaufland Sync from the Shopify App Store and open it from your Shopify admin.
Open Connect and paste your keys. See Create bol API keys or Kaufland API keys.
The setup agent checks the keys with a real call to the marketplace, then opens the Setup page. For Kaufland it also finds the storefronts where you have listings.
Review Match products: offers linked by EAN or SKU, and a short list of offers it could not link safely. Pick a variant or keep them unlinked. See EAN matching.
Check Locations (which Shopify locations feed the marketplace, and buffers) and Carriers (the marketplace code for each carrier name in your recent Shopify shipments).
Read the dry run: every offer with the number the marketplace shows now and the number it will show after go-live, the mass-zero guard's verdict, and the open orders that will be imported.
Press Go live.

What happens next

Stock, orders, tracking, cancellations and returns sync every 15 minutes, and Shopify stock changes go out as they happen.
Every hour Kizing compares both sides and fixes drift. See Drift and the mass-zero guard.
For 7 days after go-live, the Setup page shows each hourly check: open issues and what was fixed automatically.
