ProfitAxe analyzes your ad spend, orders, and inventory each morning, then surfaces the single most impactful action to take today. The current rule flags ads where 3-day spend exceeds 3-day revenue (retargeting excluded). Each card shows estimated dollar impact, a confidence label tied to order volume, the proof rows, and a Take Action button. No write scopes — every action is taken in your Shopify or ad admin. ProfitAxe surfaces the decision; you swing the axe.
