FOR VINTED SELLERS
Know your real profit on every Vinted sale, not just what the app shows
Vinted shows you the selling price. TunedBooks shows you what you actually earned after cost price, postage, packaging and fees.
TunedBooks is a bookkeeping app for Vinted sellers. Record each sale with the price you paid for the item. The app calculates your net profit automatically after postage, packaging and Vinted fees. It keeps a complete record for tax purposes and shows your running total by day, week and month. Free to start, 20 transactions per month, no card required.
The Vinted profit illusion
You sold a jacket on Vinted for £18. Vinted shows £18 in your wallet. But what did you actually earn?
Real profit on a £18 Vinted sale
| Selling price | £18.00 |
| Cost price (charity shop) | −£3.50 |
| Postage (Royal Mail 2nd class) | −£3.35 |
| Packaging (poly mailer) | −£0.30 |
| Petrol to post office | −£0.80 |
| Net profit | £10.05 |
The real profit is £10.05, not £18. That is a 56% margin, decent. But without tracking each cost, you would never know whether a £18 sale made £10 or £2. And across hundreds of sales, the difference between those two numbers is the difference between a viable side income and unpaid labour.
TunedBooks does this calculation for every sale. You enter the cost price once per item type. Postage and packaging are logged as expenses. The dashboard shows your real profit, the number that actually matters.
What TunedBooks does for Vinted sellers
Tax records for Vinted sellers in the UK
If you regularly buy items to resell on Vinted for profit, HMRC considers you a trader. That means you need to register for self-assessment and keep records of every sale, the price you paid, and your allowable expenses.
You get a £1,000 trading allowance before you owe any tax. If your total Vinted income exceeds £1,000 in a tax year, you need to file a return. Even below £1,000, keeping records protects you if HMRC asks questions, and it tells you whether your Vinted selling is worth the time.
TunedBooks creates these records as you sell. Every sale is logged with date, item, selling price, cost price, and expenses. At the end of the tax year, your records are already done. No reconstructing from memory. No scrolling through bank statements.
Note: TunedBooks is a bookkeeping app. It does not file tax returns or connect to HMRC. Consult an accountant or use HMRC-recognised software for your actual tax filing.
Your records, done as you sell.
No spreadsheet. No end-of-year scramble.
Sell on Vinted and other platforms?
Many Vinted sellers also list on eBay, Depop, or their own Shopify store. TunedBooks tracks all of them in one place. Tag each sale by platform and see which channel gives you the best margin. A dress that nets £8 on Vinted might net £11 on eBay after different fee structures, or vice versa. You cannot optimise what you do not measure.
Built for sellers, not accountants
TunedBooks is designed for the person behind the counter, or behind the phone listing items. No accounting jargon. No chart of accounts. Record a sale in under ten seconds. The app does the rest.
It works offline, which means you can record sourcing costs at the charity shop, log a sale at the post office, and check your profit on the bus home. Everything syncs when you are back on Wi-Fi.
Vinted shows you what sold. TunedBooks shows you what you earned.
Free to start. No card required.
Frequently asked questions
How do I track profit on Vinted sales?
Record each sale in TunedBooks with the selling price and cost price. The app subtracts Vinted's buyer-protection fee and your postage costs automatically. The result is your net profit per item, shown on your dashboard by day, week and month.
Do I need to keep records of my Vinted sales for tax?
If you sell regularly for profit on Vinted, HMRC considers you a trader, and you need records of every sale, the price paid, fees charged, and postage costs. TunedBooks creates these records automatically as you sell, so you have a complete audit trail at tax time.
What fees does Vinted charge sellers?
Vinted charges the buyer a buyer-protection fee, not the seller directly. However, sellers pay for postage unless the buyer covers it via the platform. If you use Vinted's optional promoted-listing feature, that has a cost. TunedBooks lets you log all of these so your profit calculation is accurate.
What is the best bookkeeping app for Vinted sellers in the UK?
TunedBooks is built for small sellers who need profit tracking without accounting complexity. Record sales, log postage and packaging costs, and see your real profit per item. It works on iOS and Android, runs offline, and starts free with 20 transactions per month.
How do I know if HMRC considers me a Vinted trader?
HMRC looks at whether you are buying items to resell for profit, selling regularly rather than clearing personal belongings, and treating it as a business. If any of these apply, you are likely trading and need to register for self-assessment and keep records. TunedBooks helps you keep those records from day one.
