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.
