Reseller Profit & Inventory Tracker

KNOW WHAT EVERY FLIP REALLY MADE.

WHY THIS ONE

• Real profit after each platform's real fee rules: eBay's fee on shipping, Poshmark's flat $2.95 under $15, Depop's processing, Whatnot's commission. All editable.
• Everything in one file: inventory with SKU or bin, sales, fees, profit, ROI, days to sell, stale-item alerts, expenses, sourcing mileage and monthly profit. No add-ons to buy.
• Built for real use: gray cells are the only place you type, and formulas are protected so nothing breaks.
• Buy once: no subscription, no app, no monthly fee.

For thrift flippers and resellers on eBay, Poshmark, Mercari, Depop, Whatnot, Facebook Marketplace and local sales.

WHAT IT DOES

• Platforms: fee rules for 7 platforms started for you (2026 rates): % fee, fixed fee, fee on shipping, flat fee under a price. Add any other place you sell.
• Inventory: one row per item: SKU or bin, item, category, where you found it, date and cost, list date and price. When it sells: platform, date, sale price, shipping the buyer paid, your label cost, ad or promo fees.
• FEES, NET, PROFIT and ROI fill in for every item, plus days to sell and a status: TO LIST, LISTED, STALE, SOLD or SOLD AT A LOSS.
• Best platforms, best sourcing spots and best categories: items sold, profit and average ROI for each, so you know where to spend your time.
• Expenses (shipping supplies, store subscription, apps, storage) and a sourcing Mileage log with the 2026 IRS rate by date.
• Monthly: items bought, spent on inventory, items sold, sales, fees, cost of what sold, expenses, mileage, PROFIT and tax set-aside. Inventory on hand and your monthly goal.
• Overview dashboard with a profit-by-month chart.
• A Start Here tab with step-by-step instructions.

WHAT THIS IS NOT (no surprises)

• Not connected to eBay, Poshmark or any platform: you type or paste your items.
• Not tax advice: the set-aside is an estimate. Fee rates change: check them on the Platforms tab.
