Stop losing money on every lot you buy
A lot bought for €80 and resold for €220 isn't €140 of profit: after fees and charges, €96 is left. Margeo works this out before you buy, then tracks inventory, sales and taxes.

The problem
Doing buy-and-resell but not sure you're actually making money?

FAQ
Frequently asked questions about reselling
What is the best free software for reselling?
Margeo is a free app built specifically for resellers. It lets you manage inventory, track sales across marketplaces, calculate margins, follow expenses and export your data. The Starter plan is free forever, no credit card.
How do you calculate margin when reselling?
The reselling margin is calculated as: selling price - purchase cost - shipping - packaging - marketplace fees - tax buffer. Margeo helps you model that before buying and then track the real sale later.
How do I manage resale records without a spreadsheet?
Use lots for purchases, items for inventory, sale records for each marketplace and expenses for recurring costs. Margeo keeps those records connected so exports and reports remain readable.
Does Margeo work with several marketplaces?
Yes. Margeo supports Vinted, eBay, Facebook Marketplace, in-person sales and custom platforms. Sales stats are broken down by platform to identify your most profitable channels.
Can I adapt Margeo to my local taxes?
Yes. Use the simulator and expense fields with your own tax or fee assumptions. Country-specific obligations differ, so Margeo focuses the English workflow on clean records, margin visibility and exportable data.
Does Margeo work offline at flea markets?
Yes, Margeo is a Progressive Web App (PWA) that works without an internet connection. You can add purchases, check your inventory and verify your margins even at flea markets, car-boot sales or on the move with no signal. Data syncs automatically when you're back online.
What types of reselling is it suited for?
Margeo is built for every kind of buy-and-resell: clothing and thrift, tech and electronics, video games and consoles, furniture and decor, books, jewellery, flea-market finds, Amazon lots, return pallets… You customise your catalogue, your sales platforms and your categories to fit your niche.
