Where it goes wrong

What we see trip online sellers up

None of these are hard to fix once you know they're there. They're the first things we look at with a new online sellers client.

Recording the payout as the sale — so revenue, fees and VAT are all understated and the accounts don't reflect reality.

Sailing past the £90,000 VAT threshold without noticing, because it's measured on a rolling 12 months, not the tax year.

Platforms now report seller data to HMRC — if what you declare doesn't match, questions follow.

No handle on stock, cost of sales or ad spend return — so growth eats cash without anyone realising.
