Specialist Ecommerce Accountants UK for Online Sellers
Online businesses can quickly accumulate complex sales data across marketplaces, payment gateways, suppliers and accounting systems. Accurate bookkeeping, VAT reporting and financial records are essential for understanding margins, controlling costs and meeting tax obligations as your business grows. Our highly expert ecommerce accountants UK team provide tailored accounting, bookkeeping and tax support for Amazon, Shopify, eBay, Etsy and multi-channel businesses. We bring sales data, payment transactions, expenses, VAT and financial reporting into a more organised process, giving you reliable numbers to run your business.
We support online sellers end-to-end, from bookkeeping and payment reconciliation to VAT, annual accounts, corporation tax and management reporting. Our online store accountants provide additional support for businesses operating through digital sales channels.
E-commerce Accounting Built Around Your Sales Channels
Different platforms create different settlement reports, transaction fees, refunds and payment schedules. Our team of highly expert ecommerce tax accountants can help bring these transactions into one organised accounting process, giving you clearer records and better visibility of sales, costs and profitability.
Our service can help you:
- Reconcile marketplace settlements
- Record sales and platform fees
- Match payment gateway transactions
- Track refunds and chargebacks
- Maintain accurate bookkeeping
- Monitor VAT treatment
- Prepare year-end accounts
- Review business profitability
- Support tax compliance
- Produce useful management information
This gives online business owners a more complete view of what customers paid, what platforms deducted and what the business actually earned.
VAT for E-commerce Sellers: OSS, IOSS and Marketplace Rules
VAT can become more complex as online sales grow, particularly when a business sells through multiple marketplaces or to customers overseas. Our expert ecommerce accountant UK can assess your VAT position, including the £90,000 registration threshold, marketplace transactions and relevant cross-border requirements, assessing your position and register for VAT when required.
Selling to customers in the EU can create additional VAT considerations. The One Stop Shop (OSS) can simplify reporting for eligible B2C sales to EU customers, while the Import One Stop Shop (IOSS) can apply to qualifying imported goods valued at up to €150. We can review your sales model, fulfilment arrangements and customer locations to help establish the appropriate treatment.
Marketplace rules can also determine who accounts for VAT on certain transactions. Where the platform is responsible for VAT on qualifying sales, your accounting records still need to reflect the transactions correctly. We can review your Amazon, eBay and other marketplace activity as part of your wider VAT service.
Making Tax Digital for E-commerce
Making Tax Digital for VAT is already mandatory for VAT-registered businesses, making compatible software and digital records an important part of e-commerce accounting.
For sole traders and landlords, Making Tax Digital for Income Tax applies from 6 April 2026 where qualifying income is over £50,000. The threshold reduces to over £30,000 from April 2027 and over £20,000 from April 2028. Businesses affected need digital records and quarterly updates.
Our team of best ecommerce accountants UK can assess your position, organise digital records and help integrate MTD into your existing accounting process. Our Making Tax Digital accountants page explains the full timetable and requirements.
Multi-currency Sales and Cross-border Accounting
International sales can introduce transactions in pounds, euros and US dollars, alongside overseas supplier payments and marketplace charges. Without appropriate records, exchange movements and transaction fees can make your reported sales and margins harder to assess.
Our online store accountants can help maintain accurate multi-currency records, reconcile foreign currency receipts and review the accounting treatment of cross-border transactions. This provides clearer reporting across your UK and international sales channels.
Payment Gateway Reconciliation for Online Sellers
Payment gateways rarely transfer the exact amount shown as gross sales. Stripe, PayPal, Shopify Payments and other providers can deduct fees, refunds, chargebacks and adjustments before paying funds into your bank account.
Our bookkeeping service reconciles gross sales, payment fees, refunds, VAT and net payouts, helping your accounts reflect the transactions behind each bank deposit.
This reduces unexplained differences and gives you more reliable figures for VAT returns, tax calculations and management reporting.
E-commerce Bookkeeping Across Multiple Platforms
Multi-channel businesses need bookkeeping that keeps pace with different marketplaces and payment systems. Our outsourced bookkeeping support can consolidate transactions into a consistent accounting process.
Our bookkeeping can cover:
- Marketplace sales
- Platform fees
- Bank reconciliation
- Payment gateway transactions
- Refunds and returns
- Supplier invoices
- Purchase records
- VAT transaction records
- Monthly account reviews
We support online businesses across different models, including e-commerce and retail businesses and subscription businesses with recurring payments and revenue.
Amazon, Shopify, eBay and Etsy Accounting
Each major platform creates its own accounting considerations, from settlement reports and fees to refunds and payment timing. Our service can support businesses using one platform or combining several.
- Amazon: FBA and marketplace settlement reconciliation, fees, refunds and transaction records.
- Shopify: Sales, Shopify Payments, payment gateway transactions, refunds and platform costs.
- eBay: Marketplace payments, transaction fees, refunds and sales records.
- Etsy: Bookkeeping, VAT and tax support for sellers of physical and digital products.
The objective is to create one reliable accounting process across your sales channels rather than managing separate records for every platform.
Stock, Cost of Goods Sold and Profitability
Turnover does not tell you how much your business actually makes. Product costs, shipping, fulfilment, import charges, marketplace fees and advertising can significantly affect your margins.
We can help maintain appropriate records for stock and cost of goods sold, giving you a clearer view of:
- Gross profit
- Product margins
- Channel profitability
- Stock-related costs
- Fulfilment expenditure
- Operating expenses
Better visibility can support decisions around pricing, inventory, product ranges and marketing expenditure.
Corporation Tax and E-commerce Tax Planning
The appropriate tax treatment depends on your business structure, profits and wider circumstances. Limited companies may have corporation tax obligations, while sole traders generally report profits through self-assessment.
Our Corporation Tax support can form part of a wider service covering:
- Corporation tax returns
- Self-Assessment
- Allowable expenses
- Tax planning
- Director salary and dividend planning
- Capital expenditure
- Year-end accounts
- Ongoing compliance
An ecommerce accountant UK connects all accounting records with a wider tax position, rather than treating tax as an isolated year-end task.
Management Accounts for E-commerce Growth
Growing online businesses need financial information they can act on, not simply statutory accounts at year-end.
Management reporting can help you monitor:
- Sales performance
- Gross margins
- Operating costs
- Cash flow
- Product profitability
- Marketplace performance
- Budget performance
Regular reporting gives business owners better visibility when deciding whether to increase stock, adjust pricing, invest in marketing or expand into another sales channel.
Choosing the Right Ecommerce Accountants UK
A professional accountant your business relies on should understand how online transactions actually flow, from the customer’s payment through marketplace settlement to the final bank receipt.
The service should also extend beyond bookkeeping where required, covering VAT, tax, accounts and management information. This creates a more joined-up approach as transaction volumes increase.
When comparing the best accountants for e-commerce, consider whether the provider can support your existing platforms while adapting to new marketplaces, international sales and changing accounting requirements.
E-commerce Tax and Compliance Support
Our team of ecommerce tax accountants can provide support across VAT, corporation tax, self-assessment and wider compliance requirements. The right approach depends on where you sell, how your business is structured and how your transactions are processed.
We can review your existing records, identify areas requiring attention and help establish a practical tax and accounting process. This can reduce administrative pressure while keeping your records ready for reporting and filing.
Why Choose Apex Accountants for Your E-commerce Business?
At Apex Accountants, our approach combines bookkeeping, accounting, VAT and tax support rather than treating each requirement separately. This gives online businesses access to one team as their transaction volumes and sales channels develop.
Our service can include:
- E-commerce bookkeeping
- Marketplace reconciliation
- Payment gateway reconciliation
- VAT registration and returns
- Cross-border VAT support
- Making Tax Digital
- Annual accounts
- Corporation Tax
- Self-Assessment

- Tax planning

For businesses comparing the best ecommerce accountants UK, having one provider that can cover day-to-day records alongside tax and reporting requirements can make financial administration considerably easier.

Frequently Asked Questions
An e-commerce business does not always need an accountant, but professional support helps with bookkeeping, VAT, tax returns and inventory. It becomes particularly useful when selling internationally, importing stock or using multiple platforms.
E-commerce accountants provide bookkeeping, marketplace reconciliations, VAT returns, annual accounts, tax returns, payroll and inventory reporting. They can also support cash flow forecasting, software integration and international sales, depending on your business requirements.
They reconcile platform reports against bank receipts, separating gross sales, refunds, commissions, processing charges and fulfilment fees. This helps ensure accounts reflect sales and costs accurately, rather than treating bank payouts as revenue.
UK online sellers generally need VAT registration when taxable turnover exceeds £90,000 within a rolling 12-month period. Marketplace rules, imported goods, overseas stock and international sales can create additional obligations depending on circumstances.
Choose an accountant who understands your platforms, marketplace settlements, inventory and VAT obligations. Check their software experience, reporting services and communication arrangements, and request a clear breakdown of fees, inclusions and additional charges.
Yes. An online accountant can help reconcile stock records, track purchases and relevant acquisition costs, and calculate the cost of goods sold. Accurate inventory figures support reliable gross profit reporting and better pricing decisions.
Separate registrations are not automatically required for different platforms. Additional VAT registrations may be necessary when sellers store stock or make taxable sales abroad, depending on local rules and the arrangements for transactions.
Stock costs, marketplace and payment fees, postage and packaging, software subscriptions, storage including fulfilment centres, home-office costs and professional fees are all allowable against your taxable profit. We review your platform statements quarterly to capture every category.
Yes, input VAT on stock bought for resale is recoverable in full if you are VAT-registered and the goods are for taxable sales. Hold valid invoices for each purchase. We reconcile stock purchases against marketplace fees so nothing is missed.
VAT-registered sellers must already keep digital records and file via MTD-compatible software. From 6 April 2026, sole traders and landlords with income over £50,000 must follow MTD for Income Tax with quarterly updates. We set up your e-commerce platforms to feed clean data into MTD software.
The One Stop Shop applies if you sell goods to consumers in the EU and dispatch them from the UK or EU stock. It lets you file one return covering all EU B2C sales instead of registering in every member state. Northern Ireland sellers use the UK OSS for EU goods. We will confirm which scheme fits your setup.
