FurimaPro — Listing templates and profit calculator for Mercari PC sellers. ━━━━━━━━━━━━━━━━━━━━━━ The Problem ━━━━━━━━━━━━━━━━━━━━━━ If you sell on Mercari regularly, you know the pain: rewriting the same listing description from scratch every time, manually calculating whether a sale is actually profitable after commission and shipping, and losing track of your monthly earnings. FurimaPro solves all three in one Chrome extension — listing templates you insert in one click, a built-in profit calculator that accounts for Mercari's 10% fee and shipping costs, and monthly sales tracking with CSV export for tax filing. All data stays in your browser. No account required. No external server. ━━━━━━━━━━━━━━━━━━━━━━ Features ━━━━━━━━━━━━━━━━━━━━━━ Template Library (Free: 3 / Pro: unlimited) • Save listing description templates by category • Insert any template into Mercari's listing form with one click • Templates store item condition, shipping method, and who pays shipping • Includes starter templates for clothing, books, and electronics Profit Calculator (Free) • Enter sale price, purchase cost, and shipping → profit calculated instantly • Mercari's 10% commission applied automatically • Built-in shipping rates for Rakuraku Mercari Bin (Nekoposu through 160-size) and Yuyu Mercari Bin (Yu-Packet through 100-size) • Real-time profit and profit margin display Sales Records (Free: 10 entries / Pro: unlimited) • Log sold items with price, cost, shipping, and category • Auto-calculates commission, profit, and profit margin per sale • Monthly totals: revenue, total costs, net profit, average margin • Auto-detection of completed sales from Mercari pages Monthly Profit Graph (Pro only) • Visualize monthly sales trends over time • Spot seasonal patterns in your reselling business CSV Export (Pro only) • Export all sales data as CSV for tax reporting • Columns: item name, sale price, purchase price, commission, shipping cost, net profit ━━━━━━━━━━━━━━━━━━━━━━ Who It's For ━━━━━━━━━━━━━━━━━━━━━━ • Resellers listing 30+ items per month on Mercari • Handmade sellers who relist similar items repeatedly • Full-time sellers who need sales tracking and tax-ready CSV export • Anyone who wants to know the real profit on each sale, not just the sale price FurimaPro works with Mercari's PC website (jp.mercari.com).

It only helps you prepare and insert text manually, and tracks sales you record. This is a productivity assistant, not a bot. Does my data go to any server? No. All templates and sales records are stored locally in chrome.storage.local. Nothing is transmitted externally. Does it work on the Mercari mobile app? No. FurimaPro works with the Mercari PC website (jp.mercari.com) only. Does it support other flea market platforms? Not yet. Mercari only in v1. Rakuma support is planned for a future update. ━━━━━━━━━━━━━━━━━━━━━━ Privacy ━━━━━━━━━━━━━━━━━━━━━━ • 100% local storage — no cloud sync, no external server • No personal information collected • No access to Mercari login credentials • No account or email required Privacy Policy: https://dev-tools-hub.xyz/privacy/ Support: https://dev-tools-hub.xyz/support/ Built by S-Hub (dev-tools-hub.xyz)
