SupplierSync connects to your suppliers' inventory feeds (CSV, Excel, XML, JSON API) via HTTP, FTP, or SFTP. It matches supplier EANs against your product barcodes using automatic GTIN-14 normalization and sets oversell policies accordingly: supplier has stock means continue selling, no stock means deny. For dropship-only products, the app automatically switches variants to a slower shipping profile. When your own stock returns, it switches back instantly.
