Stop Guessing Your Numbers.Start Scaling With Confidence.
From marketplace sellers to D2C brands โ we speak e-commerce. Multi-platform reconciliation, VAT compliance, and HMRC-ready accounting so you can focus on growing your online business.
E-Commerce Accounting Is Different. We Get That.
Running an online business means juggling platforms, payment processors, inventory, international VAT, and an HMRC that is paying closer attention than ever. These are the challenges we solve every day.
Multi-Channel Inventory Tracking
Selling across Amazon, eBay, Etsy, and your own Shopify store means stock levels, purchase costs, and returns need reconciling across every channel to get accurate cost of goods sold figures.
Marketplace Fee Reconciliation
Referral fees, fulfilment fees, storage charges, advertising costs, subscription fees โ every marketplace takes its cut differently. We break down exactly where your money goes, platform by platform.
VAT on International Sales
Post-Brexit rules mean selling to EU customers requires navigating country-specific VAT registrations, the One Stop Shop scheme, and different threshold rules. Getting it wrong means penalties and backdated charges.
Payment Processor Reconciliation
Stripe, PayPal, Klarna, Amazon Pay โ each processor holds funds differently, charges different fees, and pays out on different schedules. We match every penny from sale to bank deposit.
Cost of Goods Sold Calculations
Accurate COGS means knowing the true cost of every product including shipping to your warehouse, import duties, damaged stock, and returns. Without this, your profit figures are fiction.
HMRC's Increasing Focus on Online Sellers
Since January 2024, Amazon, eBay, Etsy, and other platforms report your sales data directly to HMRC. If your tax returns do not match what the platforms report, expect questions โ or worse.

VAT for E-Commerce Sellers โ Made Simple
VAT is one of the biggest compliance headaches for online sellers. Here is what you need to know and how we make it painless.
UK VAT registration threshold (2025). This is based on rolling 12-month taxable turnover across all your sales channels combined.
When to Register for VAT
You must register when your total taxable turnover across all platforms exceeds ยฃ90,000 in any 12-month period โ or if you expect to exceed it within the next 30 days alone. Many multi-channel sellers cross this threshold faster than they realise because turnover from Amazon, eBay, Etsy, and your own website all count together. LOYALS monitors your combined turnover proactively so you never miss the deadline.
EU and International Sales VAT
Since Brexit, selling to EU consumers requires careful consideration of each country's VAT rules. If you store goods in an EU country (such as through Amazon's Pan-European FBA programme), you likely need VAT registration in that country. For direct-to-consumer sales from the UK, the EU's One Stop Shop (OSS) scheme can simplify reporting by allowing you to declare EU VAT through a single registration.
Amazon and Marketplace VAT
Amazon, eBay, and other marketplaces now handle VAT collection on certain transactions โ particularly for goods shipped from overseas into the UK. However, this does not remove your obligation to maintain accurate VAT records, file returns, and ensure the marketplace is applying the correct rates. LOYALS reconciles what marketplaces collect on your behalf with your own VAT position to prevent double-counting or gaps.
Common VAT Mistakes Online Sellers Make
The most frequent errors we see include not monitoring the ยฃ90,000 rolling threshold across all channels, failing to register for VAT in EU countries where stock is held, incorrectly treating all international sales as zero-rated, and not reclaiming input VAT on business expenses like advertising, software subscriptions, and shipping costs. Each of these mistakes can result in backdated assessments and penalties.
Making Your Numbers Work Harder
Good accounting does not just keep HMRC happy โ it shows you exactly where to grow, what to cut, and when to scale.
Product Profitability Analysis
We calculate true margins on every product line after all fees, shipping, advertising, and returns. Stop guessing which products make money and start making data-driven decisions about your catalogue.
Fee Optimisation Strategies
Our detailed fee analysis reveals which platforms give you the best return and where you are overpaying. We help you negotiate better terms, adjust pricing, and choose the right fulfilment strategy for each channel.
FBA vs Own Fulfilment
There comes a point where running your own fulfilment is cheaper than Amazon FBA. We model the break-even point for your business so you can time the transition and protect your margins as you grow.
Scaling Tax-Efficiently
Should you incorporate? When does a salary-plus-dividends strategy save you money? How do you structure international expansion? LOYALS plans your growth so every scaling decision is tax-smart.
HMRC Is Watching Online Sellers More Closely Than Ever
Since January 2024, digital platforms including Amazon, eBay, Etsy, Vinted, and Depop have been required to collect and report seller data directly to HMRC. The first full reports were submitted by 31 January 2025, and HMRC is already using this data to send "nudge letters" to sellers whose declared income does not match platform records.
HMRC has invested heavily in recruiting additional compliance officers, and online sellers are a priority target. The tax authority can now cross-reference your platform sales data against your Self Assessment returns automatically โ and discrepancies trigger enquiries.
Here is what this means for you:
- Platforms report your identity, transaction volumes, and total earnings to HMRC annually
- Sellers with income over ยฃ1,000 who are not registered for Self Assessment face penalties
- HMRC can backdate tax bills for multiple years if undeclared income is discovered
- Making Tax Digital for Income Tax launches April 2026 for businesses earning over ยฃ50,000, requiring quarterly digital submissions
