One cockpit, not three calculators.

Work out the margin in one tool, open another for discounts, a third for ad spend — and type the same costs three times? MarginIQ replaces that. Fill in one product once — cost, platform, price — and it returns the whole decision surface at a glance: your true margin, the right price for any target, how much discount and ad spend that margin can fund, and which platform pays best.
