Resell Book is a simple record book for people who resell: clothes, sneakers, electronics, collectibles, anything you buy and sell again.

KNOW YOUR STOCK
• What you have on hand, what is listed and what is still not listed
• The value of your shelf at what you paid
• A nudge for items that have waited unlisted for over a month

ONE PRODUCT, ITS WHOLE HISTORY
• Buy the same thing again and it lands on the same product
• Every purchase is kept as it happened: "3 for 100 zł" stays exactly that
• Lifetime profit per product, added up in one place

LISTED ON SEVERAL PLATFORMS
• Mark where each item is listed: Vinted, OLX, Allegro, eBay or your own
• Selling the last piece takes it off all of them

REAL PROFIT PER SALE
• Price minus what it cost, the platform fee and shipping
• Choose which purchase a sale came from; oldest first by default
• Cash, transfer, cash on delivery or through the platform

EXTRA COSTS ON THE RIGHT PIECE
• Bought controllers for one console or a new lampshade for one lamp? Add it to that piece
• Its profit counts it; the others stay clean
• Spread one cost over several pieces, like cleaning a whole batch

CATEGORIES
• Clothing, Shoes, Electronics and more, or your own
• Filter stock and sales by category
• See which kinds of things earn the most

STATS THAT ANSWER QUESTIONS
• Profit and margin per month, platform, category and product
• How this period compares with the one before
• Best and losing products, and how many days things take to sell

PRIVATE AND OFFLINE
• No account, no ads, no tracking, no internet permission
• Your data stays on your phone
• Export a backup file any time and import it on a new phone

Available in English and Polish.
