Shopify

Connect with a Shopify app's client ID and secret (or an older custom app's access token). Products are linked to your warehouse products by SKU, customers land in the CRM, and paid orders arrive every 15 minutes as sales orders to pick, deliver and invoice — cancellations follow, and orders the store already sent out are left alone. Optionally, every 30 minutes Gochi sets each item's available count in Shopify to what you have free to sell.
