What your Amazon India payout row still hides
Referral and closing are only part of the fee stack
Category rate cards change; promotions reallocate spend. If your model uses one blended percentage, refresh it when Amazon updates fees or when you move ASINs between fulfilment modes.
Advertising belongs at the ASIN, not the account average
Blended TACOS flatters losers. Tie Sponsored Products and Brands spend to the listings it actually pushed so you know which SKUs fund the next purchase order.
Returns and inventory finish the picture
A payout row rarely captures return damage and ageing FBA stock in language your finance team can reuse. When you add multi-channel context, you see why isolated Amazon math breaks as soon as the same SKU also sells on Flipkart or your site—compare with D2C COD and RTO when relevant.
