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.

๐Ÿ“ฆ

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.

๐Ÿ’ธ

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.

๐ŸŒ

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.

๐Ÿ’ณ

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.

๐Ÿ“Š

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.

๐Ÿ”

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.

ยฃ90,000

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

โ˜…โ˜…โ˜…โ˜…โ˜…

"I was selling on three platforms and had no idea what my actual profit was after all the fees. LOYALS broke it down product by product โ€” turns out two of my best-selling items were barely breaking even. That analysis alone paid for a year of accounting."

Frequently Asked Questions

Answers to the most common e-commerce accounting questions we hear from online sellers across London.

How do I account for Amazon FBA fees and commissions? +
Amazon FBA involves multiple fee types including referral fees, fulfilment fees, monthly and long-term storage fees, and advertising costs. Each one needs to be tracked separately and reconciled against your settlement reports. LOYALS analyses your Amazon Seller Central data alongside your bank deposits so every fee is captured, every allowable expense is claimed, and your true product-level profitability is clear. This means you know exactly how much you are keeping from every sale โ€” not just what Amazon shows on the surface.
When should I register for VAT as an online seller? +
You must register for VAT when your taxable turnover exceeds ยฃ90,000 in any rolling 12-month period. This includes sales across every platform โ€” Amazon, eBay, Etsy, your own website โ€” all added together. Many e-commerce sellers cross this threshold faster than they expect because multi-channel revenue accumulates quickly. LOYALS monitors your combined turnover proactively so you never miss the registration deadline and risk backdated VAT charges. We also advise on whether voluntary registration (even below the threshold) could benefit your business through input VAT reclaim.
Can I claim for products sent as free samples or giveaways? +
Yes, products given away for business promotion purposes are generally allowable expenses. This includes items sent to influencers, reviewers, competition winners, or as promotional giveaways. The key is documenting the business purpose clearly โ€” who received the product, why, and what promotional activity resulted. LOYALS helps e-commerce clients structure and record these expenses properly so they stand up to HMRC scrutiny and reduce your tax bill legitimately.
How do I track inventory across multiple platforms? +
Multi-platform inventory tracking requires reconciling stock levels and costs across Amazon, eBay, Shopify, and any other channels you sell through. You need to account for opening stock, new purchases (including shipping and duties), returns, damaged goods, and closing stock to calculate accurate cost of goods sold. LOYALS sets up systematic inventory tracking that feeds directly into your accounts, giving you clear visibility of your true profitability โ€” not just by channel, but by individual product.
Do I need to charge VAT on international sales? +
It depends on the destination and your circumstances. UK consumer sales attract VAT at 20% once you are registered. For EU customers, post-Brexit rules mean you may need to register in individual EU countries or use the One Stop Shop (OSS) scheme. If you hold stock in EU warehouses through programmes like Amazon Pan-European FBA, you almost certainly need EU VAT registrations. Sales outside the EU are generally zero-rated for VAT purposes. LOYALS navigates these complex international rules so your e-commerce business charges the right VAT in the right places.
What does HMRC's digital platform reporting mean for me? +
Since January 2024, platforms like Amazon, eBay, and Etsy report seller data โ€” including your identity, transaction volumes, and total earnings โ€” directly to HMRC. Reports are submitted by 31 January each year. HMRC uses this data to cross-check your Self Assessment returns and has already started sending enquiry letters to sellers where the numbers do not match. If you have been earning above the ยฃ1,000 trading allowance without declaring it, HMRC now has the data to find out. LOYALS ensures your tax returns align precisely with what platforms are reporting.
How much does an e-commerce accountant cost? +
LOYALS offers three packages tailored to e-commerce businesses. Premium Accounting costs ยฃ150 per month and includes full chartered accounting with multi-platform reconciliation. Business Mentor costs ยฃ250 per month and adds a dedicated mentor for growth strategy and product profitability analysis. The Business Growth Programme at ยฃ2,000 per month provides a complete business team including marketing, legal, and sales support. For self-employed sellers, Self Assessment starts from ยฃ300 one-off (under ยฃ50K turnover) or ยฃ600 per year (ยฃ50K+ with MTD quarterly filing). We are open seven days a week including weekends.
Should I set up a limited company for my online store? +
If your e-commerce profits consistently exceed ยฃ50,000, incorporating as a limited company can reduce your overall tax through a salary-plus-dividends strategy. You also gain limited liability protection โ€” particularly important if you hold significant inventory or deal with international suppliers. However, incorporation comes with additional responsibilities and costs including Companies House filing and more complex accounting. LOYALS models both scenarios with your real numbers so you can make the decision based on data rather than guesswork.
Can my accountant help reduce my marketplace fees? +
While we cannot change marketplace fee rates, our detailed fee analysis reveals exactly how much each platform costs you per product. This data helps you make strategic decisions about which platforms to prioritise, when to launch your own direct-to-consumer website, and whether switching from FBA to self-fulfilment makes financial sense. Many LOYALS clients save thousands annually by optimising their channel mix and pricing strategy based on our profitability analysis.
What records do I need to keep as an online seller? +
HMRC requires records of all sales and income, purchase invoices and receipts, bank statements, platform settlement reports, inventory records, shipping costs, and any import or export documentation. All records must be kept for at least five years after the Self Assessment filing deadline. With Making Tax Digital for Income Tax launching April 2026 for businesses turning over ยฃ50,000 or more, digital record-keeping is now essential. LOYALS sets up cloud-based systems that automate this process, keeping you compliant with zero admin burden.
How is dropshipping taxed in the UK? +
Dropshipping income is taxed like any other self-employment or business income. You pay Income Tax on profits above your Personal Allowance (ยฃ12,570) and National Insurance Contributions on profits above the relevant thresholds. If your turnover exceeds ยฃ90,000, you must register for VAT. The main challenge with dropshipping is accurately tracking costs when you never physically handle stock โ€” supplier invoices, platform fees, advertising spend, and payment processor charges all need careful recording. LOYALS helps dropshippers maintain clean, compliant records and claim every legitimate expense.
Do I need to file a tax return if I sell on eBay as a hobby? +
If you earn more than ยฃ1,000 from selling items you bought or made with the intention of reselling at a profit, you must register for Self Assessment and file a tax return. Selling personal belongings at a loss โ€” for example, clearing out your wardrobe โ€” is generally not taxable. However, HMRC now receives platform data directly, and if your selling patterns look like trading, you may receive an enquiry letter asking you to explain. LOYALS can assess your situation, determine whether your activity crosses the line into trading, and ensure you are properly registered if needed.
