The problem
Doing buy-and-resell but not sure you're actually making money?
Unreadable Excel spreadsheets, rough margin guesses, fuzzy micro-business taxes, no way to tell which lot is profitable… You're not alone. Most Vinted and Leboncoin resellers lose money without realising it, for lack of the right tool.
Margeo solves all of this in one app
A buy & resell management app built by a reseller, for resellers. Inventory, sales, margins, taxes — everything is automated. Know exactly how much you earn on every item, every lot, every platform.
Features

AI assistant for resellers
The AI analyzes your sales figures, inventory and margins to give you personalized advice. Ask it to evaluate a lot, suggest a price or optimize your reselling strategy.

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 on Vinted, Leboncoin, eBay and other platforms, calculate your margins and handle micro-business taxes (ACRE, contributions, flat-rate payment). 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 price - Fees (shipping, packaging) - Tax charges. As a micro-business, charges are 12.3% of revenue (contributions) + 1% (income tax), totaling 13.3% of the selling price. With ACRE, contributions drop to 6.2% for 12 months. Margeo automates this with its built-in profitability simulator.
How to manage micro-business accounting for reselling?
As a micro-business (micro-BIC), accounting is simplified: you declare your revenue (selling price, not margin). Contributions are calculated on total revenue. Margeo helps you track declared sales, automatically calculates your charges and shows your net profit after taxes.
Does Margeo work with Vinted and Leboncoin?
Yes, Margeo supports all reselling platforms: Vinted, Leboncoin, eBay, Facebook Marketplace, and you can add your own custom platforms. Sales stats are broken down by platform to identify your most profitable channels.
What is ACRE for micro-business resellers?
ACRE (a French start-up relief scheme) cuts micro-entrepreneurs' social contributions from 12.3% to 6.2% for the first 12 months of activity. It's a significant advantage for resellers getting started. Margeo factors ACRE into every calculation with an automatic countdown.
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.
Is my data secure?
Your data is stored on Google Firebase (Google Cloud infrastructure), encrypted and accessible only by your account. No other user can see your data. Margeo is GDPR compliant and hosted in Europe.
What is the €79 lifetime Pro plan?
The Lifetime Pro plan is a one-off €79 payment that unlocks every Pro feature for life (unlimited items, packs, simulations and AI, photos, receipts, full ACRE / flat-rate / DAC7 tax handling) with no monthly subscription. Lifetime updates included. Worth ~10 months of regular Pro, so it pays for itself in under a year. Limited spots — the price will then rise to €159. See the Lifetime Pro plan →
No risk, no credit card
The Starter plan is free forever. Your data stays yours, exportable any time in CSV/JSON. Cancel your Pro subscription in 1 click. EU-hosted, GDPR compliant.
