Stop using a reselling spreadsheet (here’s what to track instead)

Every reseller starts with a spreadsheet. And every reseller who scales eventually curses it. If you’re selling across Vinted, eBay and Depop, a spreadsheet is quietly costing you money. Here’s why, and what to track instead.

Why the spreadsheet breaks

• You forget to update it. A sale happens on your phone; the spreadsheet is on your laptop. The gap is where your numbers go wrong.
• Fees are invisible. Vinted, eBay and Depop each take a different cut. If your sheet only tracks “sold for £25,” you don’t know your real profit.
• No live stock view. Which items are still listed? Which sold where? A spreadsheet won’t tell you at a glance.
• It doesn’t scale. 20 items is fine. 200 is a nightmare of copy-paste and broken formulas.

What you should actually track per item

For every item, you want the full profit story:

1. Cost, what you paid to source it
2. Platform, where it sold
3. Sale price, what the buyer paid
4. Fees, the platform’s cut (and postage, if you cover it)
5. Profit, sale price minus cost minus fees
6. Days to sell, how long your money was tied up

That last two are what separate hobbyists from people running a real reselling business. Profit per item tells you what’s worth sourcing again. Days to sell tells you where your cash is stuck.

The faster way

This is exactly the problem Turnover solves. You log an item once, mark it sold when it goes, and it does the fee maths for you, showing real profit per item, capital tied up in unsold stock, and an ageing view of what’s been sitting too long. It prepares a paste-ready listing for each marketplace and, when something sells, a checklist of everywhere else to delist. It never logs into your accounts, so it works alongside any crosslister you already use.

Your numbers are never sold. Turn on Vault, which is free on every plan, and they are encrypted on your device. It’s on your phone where the sales actually happen.

Keep the spreadsheet if you like it. But if you’ve ever finished a good month and had no idea whether you actually made money, that’s the spreadsheet talking.
