Workflow

A cleaner loop from sourcing to publishing.

Marginra is built around the way resellers actually work: decide if the buy makes sense, price it properly, then publish a stronger listing.

01

Start with the item

Add the cost and sale idea, or run a market search before you buy.

02

Check the margin

See ROI, fees, break-even price, and target-profit pricing before the listing goes live.

03

Publish with fewer loose ends

Draft the listing, review weak spots, and keep the numbers attached to the sale.

Use cases

Built for different selling styles.

Whether you list on weekends or manage a larger pipeline, Marginra keeps the important parts close: numbers, listings, market checks, and saved work.

Solo flippers

Keep the buy-list-sell loop in one place without rebuilding a spreadsheet every week.

Weekend resellers

Make faster sourcing decisions when time is limited and every pickup needs to count.

Multi-platform sellers

Keep pricing, listing quality, and profitability visible across a bigger inventory flow.

Growing resale shops
