Platform expertise

We Know Your Platform

Every platform has its own fee structure, payout quirks, and tax implications. We've sold on them ourselves - so we know exactly what to look for in your books.

Important for all sellers - regardless of platform

All platforms now report seller data to HMRC under DAC7 rules

Income from multiple platforms is combined for VAT threshold purposes

The £1,000 trading allowance applies across all your selling activity - not per platform

Expenses can be claimed across all platforms proportionally

Platform by platform

Every Platform, Properly Handled

We don't treat all platforms the same - because they aren't. Here's what we focus on for each one.

Whatnot

Live auction selling with complex payout structures

Whatnot payouts combine buyer premiums, shipping credits, and platform fees in ways that can make your actual profit hard to see. We untangle the numbers so you know exactly what you're earning per show.

What we focus on

  • Reconciling show payouts against individual sales
  • Tracking buyer premium income vs. your take-home
  • Shipping credit and label cost matching
  • Understanding your true profit per live show

eBay

The original marketplace - with plenty of tax complexity

eBay has been reporting seller data to HMRC since 2024 under DAC7 rules. If you're selling regularly, HMRC already knows. We make sure your records match what's been reported and that you're claiming everything you're entitled to.

What we focus on

  • DAC7 seller data reporting compliance
  • Final value fee and promoted listing cost tracking
  • Returns and refund impact on your profit
  • Managed payments reconciliation

eBay Live

Live selling on eBay - a newer income stream with its own quirks

eBay Live combines the complexity of live selling with eBay's standard fee structure. We track your live show income separately so you can see how it compares to your regular listings.

What we focus on

  • Separating live show income from standard listings
  • Live-specific fee tracking
  • Viewer engagement vs. conversion cost analysis
  • Combined eBay income reporting for self-assessment

Vinted

No seller fees - but income still needs declaring

Vinted doesn't charge sellers fees, which makes it feel informal. But if you're selling regularly and making a profit, HMRC still needs to know. We help you understand when your Vinted activity becomes taxable.

What we focus on

  • Distinguishing personal selling from trading activity
  • Tracking volume and profit thresholds
  • Combining Vinted income with other platform earnings
  • Advice on the £1,000 trading allowance

Amazon

High volume, complex fees, and FBA to untangle

Amazon's fee structure - referral fees, FBA storage, fulfilment costs, advertising - can make your real margin almost invisible. We break it all down so you know what you're actually keeping.

What we focus on

  • FBA fee and storage cost reconciliation
  • Referral and closing fee tracking per category
  • Advertising spend vs. revenue analysis
  • Amazon payout reconciliation and VAT implications

TikTok Shop

Fast-growing platform with evolving commission structures

TikTok Shop is growing fast and the commission and affiliate structures are still evolving. We stay on top of how the platform pays out so your records are always accurate - even as the rules change.

What we focus on

  • Commission and affiliate income separation
  • TikTok Shop payout reconciliation
  • Tracking creator affiliate costs against revenue
  • Combined TikTok income for self-assessment

TikTok Live

Gifts, coins, and live shopping - all taxable income

TikTok Live income - whether from gifts, coins, or live shopping sales - is taxable. Many creators don't realise this until it's too late. We make sure your live income is properly recorded and declared.

What we focus on

  • Gift and coin income valuation and recording
  • Live shopping sales vs. gift income separation
  • Creator fund and live income combined reporting
  • HMRC treatment of digital gifts and tips

Shopify

Your own store - with full bookkeeping responsibility

Running your own Shopify store means you're fully responsible for your own records. No platform to report on your behalf. We set up clean bookkeeping from the start - or sort out the backlog if you're already behind.

What we focus on

  • Sales, refunds, and discount reconciliation
  • Payment gateway fee tracking (Stripe, PayPal, etc.)
  • Inventory cost of goods tracking
  • VAT on Shopify sales - UK and international

Social Media Income

Brand deals, sponsorships, and monetisation

Income from Instagram, YouTube, Facebook and other platforms - whether it's brand partnerships, ad revenue, or paid promotions - all needs to be declared. We treat your social income as the business it is.

What we focus on

  • Brand deal and sponsorship income recording
  • Ad revenue from YouTube, Facebook, etc.
  • Gifted products - when they become taxable
  • Combining social income with other trading activity

UGC Income

User-generated content as a paid service

If you're being paid to create content for brands - even if it's never posted on your own channels - that's trading income. We help UGC creators understand their tax position and keep clean records from day one.

What we focus on

  • UGC contract income recording and invoicing
  • Equipment and software expense claims
  • Home studio and props as business expenses
  • Self-assessment for UGC creators
