Overview

Accurate profit calculation depends on tracking the actual cost you paid for inventory, not just your current supplier price. SellerLegend's Cost of Goods Management system allows Amazon sellers to enter and manage COGS with time-period accuracy, ensuring profit reports reflect true historical costs as prices change. Enter COGS for each SKU individually or bulk upload costs for your entire catalog using Excel templates. Track time-period specific costs to account for supplier price changes - when your manufacturer raises prices, enter new COGS with an effective date, and SellerLegend automatically applies the correct cost to sales based on when they occurred. This prevents profit margin distortion from averaging old and new costs. See historical COGS tracking showing how each product's cost has evolved over time, helping identify price trends and negotiate better with suppliers. Simple and detailed entry modes accommodate sellers who only track basic landed cost per unit as well as those who break down component costs (manufacturing, shipping, duties, freight forwarding, etc.). COGS integrates seamlessly with profit & loss reports, ensuring every sale is assigned the accurate cost that was current when the inventory was purchased. Track landed costs including all expenses to get products into Amazon warehouses: supplier price, international shipping, customs duties, freight forwarding, inspection fees, and prep costs. View product-level profit margin analysis that updates automatically as COGS changes, helping identify which products remain profitable as costs fluctuate. Export COGS data to Excel or CSV. To speed up data entry, copy a product's COGS to the same SKU in your other euro (EUR) marketplaces.

FIFO costing: price every sale from your purchase lots

If you buy the same product in batches at different prices, you can switch that product to FIFO. Record each purchase as a lot, and SellerLegend uses your lots up oldest first as you sell, so your COGS, profit and margins follow the stock you are actually selling.

  • Days whose sales span two lots get a blended cost of both
  • Returns, removal orders and disposals are counted too
  • A Lots Exhausted alert tells you when to record your next purchase
  • Choose FIFO product by product, and switch back to cost periods at any time

FIFO is in beta and available for the US marketplace only for now. Cost periods remain the standard method for every other product and marketplace.
