Two margins answer two different questions.

Gross margin tests the product economics.

Net sales minus COGS shows whether the product and its landed cost leave enough room to operate.

Contribution margin tests the growth engine.

Subtracting payment, marketing, fulfillment, shipping, and app costs shows what each sales period contributes toward fixed overhead and profit.

A percentage tells you what happened. Optagen helps find what changed it.

Connect Shopify to rank margin, returns, pricing, demand, and visibility opportunities by expected payoff.
