MarginIndex publishes independent analyses of e-commerce platforms and selling models. Each analysis focuses on where margins are created — and where they silently disappear.
What these analyses cover
Break-even
Where selling stops making economic sense.
Platform fees
Published fees and fee stacking across platforms.
Hidden costs
Operational and indirect costs often left out of calculations.
Margin pressure
Price competition, returns, and structural pressure on profit.
