Most B2B proposals fail on profit, not design. Expensive tools charge $30/mo, while messy spreadsheets leak margins. MARGIN | X is a 100% free, lightweight B2B proposal builder. It lets freelancers and agencies draft clean, corporate PDF proposals while dynamically calculating hidden costs, markup, and gross profit in real time. Zero subscriptions, no signups, and your private margins never leak onto the client PDF. Pure browser-side efficiency for profitable client acquisition.
