Expense Tracking

Claim everything you're entitled to.

Expense Tracking

Most sellers dramatically under-claim their expenses. Platform fees, postage, packaging, subscriptions, equipment, home office costs, mileage - we identify every legitimate deduction so you only pay tax on your actual profit.

Common questions

Quick Answers

Do I need to register for self-assessment as a reseller?

If your trading income exceeds £1,000 in a tax year, you're required to register for self-assessment with HMRC. Even if you're below that, it can sometimes be beneficial to register. We'll advise you on your specific situation.

What is the £1,000 trading allowance?

HMRC allows you to earn up to £1,000 from trading (including reselling) without paying tax or needing to declare it. Above that, you need to register and file a self-assessment return.

How do you handle income from multiple platforms?

We consolidate income from all your selling channels - eBay, Whatnot, Vinted, TikTok Shop, Amazon and more - into a single clear picture. We understand how each platform pays out and reports, so nothing gets missed.

I've never kept proper records. Can you still help?

Absolutely. Our messy books clean-up service is designed exactly for this. We'll work through your transaction history, bank statements, and platform reports to reconstruct your records as accurately as possible.

Not sure which service you need?

Just get in touch. We'll have a conversation about where you are and what would help most.
