MarginOS is a profitability OS for DTC brands that want to stop guessing and start operating from real unit economics. It connects Shopify, 3PL/warehouse and ad platforms to give a single source of truth for SKU-level margins, CAC payback and LTGP, then surfaces profit leaks caused by COGS, shipping, discounts and returns. Merchants get a simple command center with clear profit and inventory signals, so they know which products and campaigns to scale, fix or stop.
