Pentane

Pentane is profit software for ecommerce brands, designed to show whether advertising is generating real contribution profit. It connects stores, advertising platforms, analytics, and accounting tools to bring revenue, ad spend, product costs, shipping, and fees into a live profit-and-loss view. The platform reports performance by product, channel, and day, sets breakeven ROAS and CPA targets, and provides guidance on whether to cut, hold, or scale budgets. Its free software also includes profit dashboards, scenario planning, financial analysis, alerts, and business health reports.

For brands seeking campaign management, Pentane offers the Plenum Ad Network, a managed media service that optimizes advertising against contribution profit rather than platform-reported ROAS. It runs campaigns on Meta and across more than 275 ad networks and exchanges, covering channels such as display, video, native, audio, connected TV, and digital out-of-home. Spend, delivery, and conversions are reported alongside the brand’s financial data, with conversions matched to real Shopify orders.
