View productsSee how it works

Built for the decisions sellers make every week.

Use one structured model to decide what to reprice, what to scale, what to pause, and which inventory buys deserve caution.

SKU-level margin

Track product margin after marketplace fees, logistics, payment costs, ads, returns, and taxes.

Price scenarios

Model price changes, discounts, shipping options, and promotion mechanics before launching them.

Advertising impact

See how campaign spend changes unit economics and where growth turns into profit leakage.

Marketplace connectors

Prepare for Mercado Libre, Mercado Livre, and Amazon data flows from one account model.

Tax-ready structure

Keep taxes and regional cost assumptions visible instead of burying them in spreadsheets.

Cash flow view

Understand payables, receivables, inventory pressure, and cash conversion across channels.

From order to digital delivery.

Choose the marketplace table, complete checkout, then receive the digital workflow and onboarding questions by email.
