Direct answer

Keep enough evidence to show what you sold, whether it was personal or trading stock, what it cost, what fees were charged and what profit was made if the activity is taxable.

What matters in practice

If a platform reports figures, HMRC may see gross sales without the full context.
Good records help show the difference between a clear-out and a trade.
For real trading, records also support expenses and tax return figures.

Most bad decisions happen because people look for a broad rule and apply it to a narrow situation. The safer approach is to name the income source, the tax year, the gross amount, the costs, the deadline and what HMRC or the platform may already know. That turns a vague worry into a short list of checks.

Examples of how this can play out

You sell personal clothing. Keep a simple note that items were owned personally and sold below original cost where possible.
You resell stock. Keep purchase costs, sale prices, fees and postage.
You mix clear-outs and trading. Separate the two lists so the story is clear.

These examples are deliberately practical because they match the questions people actually ask in forums: mixed income, platform statements, software worries, and first-time tax returns. If your facts sit between two examples, make a note of the difference before speaking to an accountant.

What to prepare before asking for help

sales export
purchase receipts where available
platform fee statements
postage records
notes on personal possessions versus resale stock

Good preparation makes advice cheaper and faster. Send totals, not screenshots alone. Keep a separate note of anything you are unsure about so the accountant can focus on judgement rather than basic sorting.

What this guide is focusing on

Use this guide if you sell through platforms who sees payouts, fees, refunds and stock costs in different dashboards and wants to know what figure matters. For What tax records should Vinted and eBay sellers keep if HMRC asks, focus on how the rule meets the records, thresholds, software and decisions you actually have in front of you.

What figure, record or decision should you pin down?

Pin down gross sales before fees, platform payouts, refunds, postage, stock, samples, adverts, supplier costs and whether the activity is trading. That gives an accountant something specific to check and stops the conversation becoming a vague discussion about tax in general.

Records to gather

platform sales export
payment processor report
fees and refunds
stock or supplier invoices
postage, packaging and advert costs

Real examples for this situation

A Vinted clear-out is different from buying stock to resell, even if both use the same app.
An Etsy seller may receive a payout after fees, but the sales report explains gross sales and deductions.
A Shopify seller using PayPal and Stripe should reconcile the shop orders with payment processor deposits.

A common mistake is using the bank payout as the sales figure without checking platform fees and refunds. The safest pattern is to write down the figure, source, date and evidence before deciding whether DIY, software or accountant support is enough.

When to speak to an accountant

Speak to an accountant if the answer affects registration, VAT, MTD, company structure, a tax return, a penalty, or whether you should change how records are kept. You do not always need a long engagement. Sometimes the valuable thing is a focused check before you commit to software, filing or a business structure.

For this topic, the most useful accountant will explain the next step in plain English, tell you what records are missing and give you a clear scope before quoting for ongoing work.

Questions to ask an accountant

What would I show HMRC if asked
Do I need a spreadsheet for this
Which costs can reduce trading profit
Should I separate personal clear-out sales from business sales
When does this become Self Assessment

Mistakes to avoid

Keeping only bank deposits.
Deleting platform statements.
Mixing old personal items and bought-for-resale stock.
Waiting for a query before reconstructing records.

A simple evidence file is enough for many sellers

For casual sellers, the best record system is usually boring: a folder of platform exports, a note explaining whether items were personal possessions, and any available purchase evidence for higher-value items. For traders, the file needs to be stronger: purchase costs, sale prices, platform fees, postage, packaging, refunds and stock held at the year end. The more your activity looks planned and profit-seeking, the more your records should look like business records.

The practical aim is simple: decide what records prove your position, where the judgement call sits and whether a short accountant conversation would save time before you file.

Key takeaway

Keep enough evidence to show what you sold, whether it was personal or trading stock, what it cost, what fees were charged and what profit was made if the activity is taxable. The opportunity is to get the record-keeping and decision point right early, before a small admin issue becomes a deadline problem.
