The Used Electronics Flipper's Kit — Listing Templates, Testing Checklists & Profit Tracker

Flip used tech with a system, not guesswork.

If you buy and resell used phones, laptops, consoles, monitors or headphones on Facebook Marketplace, eBay, Mercari, OfferUp or Swappa, you know where the money leaks out: overpaying, buying something that's still iCloud-locked, vague listings that bring in time-wasters, and forgetting fees and shipping when you work out your "profit".

This kit gives you a simple repeatable workflow and the files to run it: research → max offer → test → list → sell safely → track.

What's included

📘 The Flipper's Guide (10-page PDF)

• What to flip as a beginner, and what to avoid (locked phones, "just needs a battery", too-good-to-be-true sealed items)
• Pricing from sold comps, not asking prices
• The max-offer formula: work out what to pay before you message the seller
• Testing and lock checks: activation lock, Google FRP, IMEI blacklist, BIOS/MDM locks, console bans, stick drift
• Stolen-goods red flags
• Cleaning, data wiping, phone-camera photo setup and shot list
• Title formula and description structure that answer buyers' questions up front
• Marketplace fee cheat sheet for the US & UK (checked October 2026)
• Safe meetups, common scams (verification codes, overpayment, fake payment emails), shipping electronics
• Record-keeping and a first-week plan

📝 25 Listing Templates (PDF + editable text)

iPhone (unlocked and carrier-locked), Android, tablet, smartwatch, business laptop, MacBook, gaming laptop, desktop PC, GPU, monitor, peripherals, console, handheld, controllers, game lots, earbuds, headphones, speakers/hi-fi, camera body, lens, router, smart home, for-parts, and bundles, plus tips for each platform.

✅ Printable Checklists (PDF)

Pre-purchase (at the meetup), pre-listing, device-specific tests (phone, laptop, console, monitor, audio, camera), shipping and after-sale.

💬 28 Message Scripts (PDF + editable text)

Questions to ask before you buy, offers and counters, replies to "is this available?" and lowballs, hold requests, meetup confirmations, no-shows, shipping requests, and calm replies to common scams.

📊 Flip Tracker spreadsheet (Excel + Google Sheets, no macros)

• Inventory: calculates the platform fee, net profit, ROI and days to sell for each item, and flags stock that has been sitting 30+ days
• Max Offer Calculator: expected price, platform, shipping, repairs and target profit give you a max offer, a suggested opening offer, your break-even price and your profit per hour
• Price Research: enter your sold comps and get the median, low and high
• Dashboard: stock value, net profit and ROI, broken down by platform, category and month
• Editable Fee Settings: eBay, Mercari, Facebook Marketplace, OfferUp, Swappa, Craigslist/Gumtree, Vinted UK and your own custom platforms
• Plain CSV versions included

Who it's for

• Side-sellers and beginners who want a clear process for used electronics
• People clearing out their own old devices who want a better price, safely
• Existing flippers who want ready-made templates and a tracker that includes fees

What it isn't

• No income promises. Some flips lose money; the tracker's example data even includes a loss. Your results depend on your market and your buying discipline.
• Not a course, coaching or a private group. It's a self-contained toolkit.
• Not legal or tax advice. Marketplace fees and rules change, so every fee in the tracker can be edited.
• Not affiliated with any marketplace or brand.
