Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShopify keeps each product's COGS as one number in your store's currency. When you buy in yuan, euros or dong, that number goes stale as exchange rates move, and your profit reports drift with it. CostBuffer stores each supplier's invoice amount in their currency, converts it with official exchange rates and updates Shopify's COGS field.
PNL shows what your store actually earns. It reads your orders, applies your product costs — stored on Shopify itself, with dated history so past periods stay accurate — imports your Meta ad spend daily, and deducts transaction fees, per-order duty and fixed monthly costs.
