Ecommerce accountant fees are one of the first questions we hear from Amazon, Shopify, eBay, Etsy and TikTok Shop sellers who are looking for proper financial support. Because every marketplace charges different fees, pays out in different currencies and reports sales in its own way, pricing for an ecommerce accountant rarely looks like a standard small business quote.
In this guide we break down what drives ecommerce accountant fees in the UK, what you should expect to pay in 2026, and how to make sure you are getting real value rather than just a cheap monthly invoice. If you would like a tailored quote, our team of specialist ecommerce accountants is happy to talk through your marketplaces, turnover and goals.
Why Ecommerce Accounting Costs More Than a Typical Small Business
A high street shop or a single client freelancer usually has one bank account, one till system and a handful of transactions each month. An online seller trading across Amazon, Shopify, eBay, Etsy and TikTok Shop can have five or more sales channels, multiple currencies, marketplace fees, refunds and chargebacks, plus stock sitting in different fulfilment centres. Every one of those data points has to be reconciled correctly before your VAT return or your year end accounts can be filed.
That is why ecommerce accountant fees are usually higher than a standard sole trader package, and why we always recommend working with an accountant who understands ecommerce bookkeeping rather than a generalist who treats your Amazon payout like a normal bank transfer.
What Affects the Cost of an Ecommerce Accountant in the UK
Several factors influence how much you will pay for ecommerce accounting support. The most common ones we see are:
- Annual turnover. The more revenue you process, the more transactions there are to reconcile, so fees typically scale with turnover rather than sitting at a single flat number for every business.
- Number of sales channels. A seller who only trades on Shopify will usually pay less than someone reconciling Amazon, eBay, Etsy and TikTok Shop payouts every month.
- VAT registration and OSS reporting. If you are VAT registered as an ecommerce seller or selling into the EU under the One Stop Shop scheme, your VAT returns will take longer to prepare and cost more than for a business that is not yet VAT registered.
- Legal structure. A limited company for ecommerce sellers generally costs more to run than a sole trader, since it needs statutory accounts, a corporation tax return and director paperwork on top of bookkeeping.
- Inventory and cost of goods sold. Sellers who hold stock need an accurate stock valuation at year end, which adds time to the accounts preparation process.
- Software and integrations. Whether you use Xero, QuickBooks, A2X or Link My Books affects how much manual work your accountant has to do. Our ecommerce accounting software guide explains how the right stack can actually reduce your fees over time.
- Payroll. If you employ staff or virtual assistants, payroll for ecommerce sellers is usually priced separately from your core accounting package.
Sole Trader vs Limited Company Ecommerce Accountant Fees
Many Amazon and Etsy sellers start out as sole traders and move to a limited company once turnover grows. Sole trader ecommerce accounting is usually cheaper because there are no statutory accounts or Companies House filings, just your Self Assessment and VAT if applicable. Once you incorporate, your ecommerce accountant fees will typically increase to cover your statutory accounts, corporation tax return and payroll if you take a salary. If you are not sure which structure suits your business yet, our guide on sole trader vs limited company explains the tax and cost differences in more detail, and our company formation service can help once you are ready to incorporate.
Average Ecommerce Accountant Fees in the UK in 2026
While every quote should be tailored to your own business, the ranges below give a realistic starting point for ecommerce accountant fees in the UK in 2026.
- Sole trader bookkeeping and Self Assessment. Typically £80 to £180 per month, covering monthly reconciliation and your annual Self Assessment for ecommerce sellers.
- Limited company package. Typically £150 to £350 per month, including bookkeeping, statutory accounts, corporation tax and Companies House filings.
- VAT returns. Typically £50 to £150 per return if billed separately from your core package.
- Monthly bookkeeping only. Typically £70 to £250 per month depending on transaction volume and number of channels.
- Payroll. Typically £25 to £60 per month for a small team, rising with headcount.
- Year end accounts as a standalone service. Typically £300 to £900 depending on turnover and complexity.
- CFO or part time finance director support. Typically £400 upwards per month for sellers who want forecasting, margin analysis and investor ready reporting through our CFO service.
These figures are a guide only. A seller turning over £40,000 a year on Etsy will have a very different quote to a seven figure Amazon FBA brand, which is why we always recommend a short call before you commit to a package.
Fixed Fee vs Hourly Billing for Amazon and Shopify Accounting
Most ecommerce accountants now offer fixed monthly fees rather than charging by the hour. Fixed fees give you certainty, so a busy peak season with more refunds and more transactions will not suddenly generate a surprise invoice. Hourly billing can work for one off projects, such as untangling a backlog of unreconciled Amazon payouts, but it is rarely the right long term model for a growing online seller. When comparing quotes, always ask exactly what is included in the fixed fee and what would trigger an additional charge.
What Should Be Included in Your Ecommerce Accountant’s Fee
Before comparing prices, make sure you understand what you are actually paying for. A properly priced ecommerce accounting package should include the following.
- Reconciliation of every marketplace payout, including Amazon, Shopify, eBay, Etsy and TikTok Shop, back to your bank account
- Digital records that satisfy Making Tax Digital for ecommerce sellers, supported by our MTD Income Tax service
- Preparation and filing of VAT returns, including OSS if you sell into the EU, in line with HMRC’s VAT registration guidance
- Year end accounts for ecommerce sellers, filed correctly with HMRC and Companies House
- Proactive tax planning for ecommerce sellers, not just historic reporting, backed by our specialist tax advice service
- Clear guidance on salary vs dividends for ecommerce sellers if you trade through a limited company
- Regular check ins so you understand your profit margins, not just your revenue
If any of these are missing from a quote, ask why, because they are the items that keep you compliant and help you avoid a much larger bill later, including the kind of common ecommerce accounting mistakes that lead to HMRC penalties.
Hidden Costs and Add Ons to Ask About Before You Sign Up
A low headline price is not always the best deal. Some of the extra costs we see ecommerce sellers charged for elsewhere include per channel reconciliation fees on top of the core package, separate charges for every VAT return rather than one included price, additional fees for payroll or company formation, and charges for basic email or phone support.
Before you sign up, ask your accountant to confirm in writing exactly which marketplaces, currencies and services are covered in the price you have been quoted, and whether a company formation or payroll management add on will change your monthly invoice.
How to Get the Best Value From an Ecommerce Accountant
The cheapest quote is rarely the best value once you factor in missed VAT deadlines, incorrect stock valuations or a tax bill that could have been reduced with better planning. Our guide on how to choose an ecommerce accountant covers the questions to ask before you switch, but as a quick summary, look for a firm that specialises in marketplace sellers, offers a fixed monthly fee, uses ecommerce friendly software and is happy to explain exactly what your fee includes.
