Third-party cookies are being deprecated across all major browsers. iOS limits tracking to 7 days, Safari blocks via ITP, and Chrome has implemented Privacy Sandbox. The result: Ads platforms like Meta and Google systematically overestimate conversions, creating a gap between reported spend and real profit that can exceed 30%.

Growth OS connects to your Shopify via OAuth2 and automatically imports orders, products, and costs. It cross-references this data with the ad spend from Meta, Google, and TikTok via server-side tracking. The True Profit calculation subtracts COGS, shipping costs, gateway fees, and taxes from the gross revenue, returning the real operating EBITDA.
OAuth2 is the standard authorization protocol used by Shopify, Google, and Meta. Unlike browser pixels, OAuth2 establishes an authenticated and encrypted server-to-server connection. Data comes directly from the Shopify database — not interpreted by a cookie — radically eliminating tracking discrepancies. Growth OS uses server-side ingestion to import every order in real-time with Zero-switch login into its multi-tenant workspace.
Growth OS automatically imports the cost of goods sold (COGS) from your Shopify catalog via OAuth2. When an order comes in, the system instantly calculates the cost of goods sold for each line item, without Excel sheets or manual CSV imports. This eliminates human error and guarantees a margin calculation accurate to the cent.
