Sell-Through System Decision Spreadsheet for eBay Sellers (BUY / PASS Logic)
What this is
The Sell-Through System is a practical spreadsheet toolkit for eBay sellers who want to make better buying decisions.
It combines:
- Profit math
- Sell-through velocity
- Shipping safety
- Expiration risk
Into one clear result:
🟢 BUY · 🟡 CONDITIONAL · 🔴 PASS
No hype. No guesswork.
Who this is for
This tool is for:
- eBay sellers doing retail arbitrage or resale
- Sellers tired of slow inventory and bad buys
- People who want fewer mistakes, not more products
This is not a course, a BOLO list, or a get-rich-quick system.
It’s a decision engine.
What you get
1️⃣ PRODUCT RESEARCH TAB (Main Engine)
Use this at home for full research.
You enter:
- Buy price
- Average sold price
- Shipping & other costs
- Active listings
- Sold (last 30 days)
- Expiration (months)
- Risk flag (manual awareness)
The sheet calculates:
- Fees
- Total cost
- Net profit
- Profit margin
- Sell-through %
-
BUY / CONDITIONAL / PASS
2️⃣ IN-STORE QUICK CHECK (Phone-Friendly)
Use this while standing in a store.
Enter a few numbers → get an instant decision.
Designed for speed, not spreadsheets.
3️⃣ SHIPPING WEIGHT SAFETY
Avoid USPS and carrier adjustments.
- Converts ounces to pounds
- Rounds weight up safely
- Flags risk before you print a label
Overpaying slightly is cheaper than an adjustment.
How to read the result
🟢 BUY
Strong sell-through, acceptable profit, manageable risk.
🟡 CONDITIONAL
Profitable, but with tradeoffs. Buy cautiously or test small quantities.
🔴 PASS
Slow sales, weak profit, or elevated risk.
Passing protects your capital.
Passing is a win.

To help you make fewer mistakes.
Used consistently, it becomes a competitive advantage.
Stop guessing. This spreadsheet tells you BUY, CONDITIONAL, or PASS before you spend money on inventory.
