Threecolts sponsored GROW Pet on 7 October and GROW F&B on 8 October 2026.
Why marketplaces and the Shopify store need to work together
Brands that sell on their own Shopify store and on Amazon need product data, pricing and stock to stay consistent across both. The more channels a brand sells through, the more it matters that the store and its systems share one source of product and stock data.
