SellerLens: Resale Profit Calc

SellerLens is the profit calculator and inventory tracker for resellers who want to know what they really earn. Enter a sale price and see your real net profit after marketplace fees, shipping, packaging and what the item cost you, before you list it. Whether you flip clothes, sneakers, electronics, books, furniture or collectibles, SellerLens turns every sale into clear, exact numbers. 💰 KNOW YOUR REAL PROFIT BEFORE YOU LIST • Net profit, margin, ROI and break-even price, updated as you type. • A visual breakdown shows exactly where every cent goes. • Compare the same sale across your fee profiles to see where you keep more. • Optional tax assumption for a quick after-tax estimate. 📦 TRACK EVERY ITEM FROM PURCHASE TO SALE • Purchased, ready to list, listed, sold, returned or archived, with a full timeline. • Photos from your camera or gallery, kept privately on your phone. • Repairs, cleaning and other extra costs counted in each item's profit. • Record the real sale and compare estimated vs. realized profit. • Fast search, filters and sorting across your whole inventory. 📈 INSIGHTS FROM YOUR REAL SALES • Revenue, net profit and margin over 7 days, 30 days, 90 days, a year or all time. • Monthly performance, best categories and period-over-period comparisons. • Inventory value at cost and expected sales of what you're holding. • Every chart is built only from what you record. No estimates, no invented data. 🧾 FEES YOU CONTROL SellerLens is not connected to any marketplace. Fee templates start empty and stay marked "unverified" until you enter and confirm the rates from your own seller account, so your numbers always match your reality. 🎯 PRECISE BY DESIGN • Exact decimal arithmetic in your currency's precision, never rounding drift. • Multiple currencies, never mixed together. • English and Spanish, light and dark themes. 🔒 PRIVATE BY DEFAULT • No account required: your data stays on your phone. • No ads, no tracking, no selling of data. ⭐ SELLERLENS PRO An optional upgrade for serious resellers: • Unlimited items (the free plan saves up to 15). • Full analytics history (the free plan shows the last 30 days). • Custom fee templates and dashboard customization. • CSV exports of your inventory, sales and profit summary. • Cloud backup and sync across your devices. Choose monthly, yearly or, where offered, a one-time lifetime purchase. Subscriptions renew automatically and can be cancelled anytime in Google Play. If Pro ends, nothing you recorded is deleted or hidden. SellerLens is a personal bookkeeping tool. Tax figures are estimates and exports are not official tax documents.
