GemCraft × BaseLinker Module
Syncs 495 SKUs live across 6 marketplaces — Etsy, Allegro, Amazon Handmade, Kaufland, eBay, Sashe.
The problem
GemCraft sells hand-blown glass, ceramics and wood items on six marketplaces at once. Marketplaces aren't a place you list once — they're a daily price-stock-content loop, and keeping 495 SKUs consistent across channels by hand breaks within a week.
What we built
An async Python BaseLinker client with token-bucket throttling (100 requests/min), automatic retry on rate limits and 5xx errors, bulk catalogue calls of up to 1,000 products, multi-currency support and per-channel price-group strategies. The Upgates store stays the single source of truth and fans out to Allegro, Etsy, Amazon Handmade, Kaufland, eBay and Sashe.sk.
The result
495 SKUs live across six marketplaces with stock, pricing and listings kept in sync hands-off — cross-channel inventory as a running loop instead of a manual chore.
