Enter one set of figures — sale price, item cost, postage and VAT status — and compare net profit, margin and ROI across every UK marketplace at once.
Results update as you type: each marketplace is ranked by take-home profit, with fees itemised so you can see final value fees, payment processing, per-order charges, regulatory fees and VAT separately.
Switch VAT registration on or off, adjust postage to you and to your buyer, and the ranking recalculates instantly — no Calculate button, no sign-up.
