For UK online sellers

Turn the mess into a figure you can defend.

Had a nudge letter from HMRC about your eBay, Vinted or Etsy sales — or worried one's coming? ExpenseTidy rebuilds your PayPal and bank exports into a clean, gross-to-net record you can actually stand behind.

Sound familiar?

The letter lands, and suddenly you owe two years of records you never kept.

01

The gross-vs-net trap

You sold for £100, £82.95 hit your account — and HMRC wants the £100 declared. Get that one wrong and every figure after it is wrong too.

net £82.95 → gross £100.00
02

Exports that don't agree

PayPal says one thing, your bank another, the platform a third. Matching fees and postage to each sale by hand is a weekend you'll never get back.

A deadline with teeth

Penalties can land on top of the tax owed — and they climb the longer a letter sits unanswered. The clock starts the day it arrives.

The figure that trips everyone

Gross is what you sold for — not what you kept.

This is the single thing that catches sellers out. Your taxable income starts from the full price the buyer paid, before the platform took its cut and before postage came out. Those costs come off later, as expenses — but only if you can show them.

ExpenseTidy reads each export, matches the fees and postage back to the sale they belong to, and rebuilds the true gross figure — with every line traceable to the statement it came from.

A £100 sale is £100 of income. The £17 of fees and postage is a deduction — kept separate, evidenced, ready.

How it works

Three steps from a shoebox of exports to a tidy record.

01

Export

Download whatever you've got — PayPal, your bank, eBay, Vinted, Etsy. CSV files, however messy. No need to tidy them first.

02

Reconstruct

ExpenseTidy reads them right here in your browser, matches fees and postage to each sale, and rebuilds your true gross-to-net figures.

03

Stand behind it

You get a clean summary and a line-by-line trail — the paper you, or your accountant, need the moment HMRC asks "where's this from?"

Let's be straight

What ExpenseTidy is — and what it isn't.

Being clear about this is the whole point. You're holding evidence, not advice.

It is

  • A way to turn raw exports into an organised, defensible record.
  • A clear trail behind every figure, so nothing is a guess.
  • Run on your own machine — your financial data stays with you.

It isn't

  • A filing tool — it won't submit your return for you.
  • Tax advice, and it isn't your accountant.
  • A verdict on what you owe — it shows what happened, clearly.

Questions worth asking

The honest answers.

Yes — because it never reaches us. Your statements are read and processed inside your own browser. They aren't uploaded to a server, so there's nothing of yours sitting on ours to lose.

No. ExpenseTidy organises your records into clear evidence — it doesn't tell you what to declare or what you owe. For advice on your specific position, speak to a qualified accountant. The tool simply makes their job, and yours, far quicker.

It depends on whether HMRC sees you as trading, and on your other income. Selling off your own old things at a loss usually isn't taxable; buying to resell often is. The free guide walks through how that line is drawn.

Anything you can export as a CSV — PayPal, most UK banks, eBay, Vinted, Etsy, Depop and Amazon among them. If you can download a statement, ExpenseTidy can read it.

It's the best time. Reconstructing your records now, calmly, is far easier than scrambling after a letter arrives with a 30-day deadline attached. Tidy once, and you're ready either way.
