Cost of Goods Sold (COGS) is the single most important number in your Amazon P&L statement. Get it wrong, and you'll overprice products, underprice winners, or completely misunderstand your true profitability. Yet most Amazon sellers struggle with COGS tracking because of price fluctuations, currency changes, and multi-component landed costs.
This guide covers everything you need to master COGS tracking: what to include in your calculations, different tracking methods, period-based management, and proven optimization strategies that reduce costs by 15-30%.
COGS Definition:
Cost of Goods Sold is the total direct cost to acquire and deliver your product to Amazon's warehouse, ready for sale. It includes product cost, international shipping, customs, freight forwarding, inspection, prep, and domestic freight to FBA.
Why this matters: A 1% error in COGS becomes a 1-2% error in your contribution margin calculation. At $1M revenue, that's $10K-$20K in misallocated profit that affects pricing, inventory, and growth decisions.
Nova's COGS manager handles price changes, currency fluctuations, and multi-supplier tracking automatically. Set it once, get accurate margins forever.
