Based on the defined relationship merchants can adjust case quantities when units are sold, ensuring accurate stock management.

Never oversell again and let Trunk give an extra helping hand with your inventory, giving you back the bandwidth to grow and sell on even more places. Connect all your sales channels with Shopify including: multiple Shopify shops, Amazon, Bandcamp, BigCommerce, eBay, Etsy, Faire, QuickBooks Online, Square POS, Squarespace, TikTok, Walmart, Wix, WooCommerce, Xero, and more. Not selling elsewhere?
