OPEX

Your fixed costs spread across your orders

Salaries, rent, SaaS, marketing agency. Fullmetrix automatically spreads your OPEX across your orders for a true operational net profit.

The problem

OPEX are never in your profit

Gross margin is not net margin

You calculate a unit profit per order while forgetting your monthly fixed costs. The result: fictional margins that don't account for your cost structure.

Impossible to know your real profitability

Without OPEX in profit, you think you're profitable at 25% margin but are actually at 5% or even losing money. Biased decision-making.

SaaS and agency costs explode

Shopify, Klaviyo, agencies, freelancers, tools. Thousands of dollars per month never linked to the orders that finance them.

The solution
