What problem does it solve? Merchants often see revenue on their income statement but cannot compute gross margin because unit costs are not tracked, and imported goods carry freight, customs, and duties that never get allocated into product cost. This Skill guides you through entering cost prices, connecting accounting integrations, and allocating landed costs so every order reports accurate COGS. ## Core Features & Use Cases - Platform Cost Setup: Step-by-step instructions for entering cost per variant in Shopify, WooCommerce, and BigCommerce, including bulk CSV imports via Matrixify. - Accounting Integration: Connect QuickBooks or Xero (via A2X, MyWorks, or native apps) so COGS journal entries post automatically when orders are fulfilled. - Landed Cost Allocation: Allocate freight, insurance, and duties across received SKUs by value, weight, or quantity before the first sale. - Custom FIFO Ledger: TypeScript reference implementation of a perpetual inventory cost ledger with FIFO layer consumption and weighted average costing for headless storefronts. - Use Case: An electronics importer receives a shipment with a separate freight invoice weeks later; use this Skill to allocate those landed costs across purchase lots and run a variance report comparing actual costs against standard costs. ## Quick Start Ask the AI to set up COGS tracking for your Shopify store by entering variant cost prices and connecting QuickBooks for automatic margin reporting.
