Most resellers think they know their numbers.
They don’t. They look at a sale price, subtract what they paid, and assume the rest is profit. On paper, it looks like a win.
But in reality, it’s usually far less.
You sell an item for £45.
You bought it for £25.
Looks like £20 profit.
Now include:
- platform fees
- postage
- returns
- your time
That £20 disappears faster than you think.
And sometimes it’s a loss.
Most resellers never see this because they don’t track it properly. They estimate.
Time is your real cost.
That’s where money leaks.
“Made £200 this week.”
Sounds good.
But how many hours did it take?
- sourcing
- cleaning
- listing
- messaging
- packing
If that took 10 hours, you’re at £20/hour.
Maybe less.
Most resellers focus on total profit. Very few track profit per hour.
That’s a problem.
Because time is the real cost.
“I make about £15 per item on average.”
That number feels reassuring.
But averages hide reality:
- some items lose money
- some barely break even
- a few carry everything
If you rely on averages, bad buys go unnoticed.
You don’t fix what you can’t see.
If you don’t know:
- exact profit per item
- ROI
- time per flip
You’re not running a business.
You’re guessing.
And guessing doesn’t scale.
That’s the most common reason people don’t track properly.
And it’s fair.
Most spreadsheets are messy, complicated, and time-consuming.
But that’s not an excuse anymore.
You don’t need to build anything. You don’t need to understand formulas.
You just need a simple system where you enter your numbers and everything else is calculated for you.
The difference between resellers who stay stuck and those who grow is simple:
One group estimates.
The other tracks.
When you track:
- you spot bad buys quickly
- you improve your sourcing
- you understand your real margins
- you make better decisions
It’s not about working harder.
It’s about seeing clearly.
