If you sell online, your accounts are shaped by transaction volume, payment timings, marketplace deductions, delivery costs and VAT rules that do not always behave like a standard service business. CBM Accounting Ltd acts as an ecommerce accountant for UK sellers who need bookkeeping, VAT, tax and compliance support built around online trading.
From our London base, CBM Accounting supports sole traders, startups and growing SMEs across the UK. We combine cloud accounting, HMRC-focused compliance and practical advice so you can keep your records accurate, meet filing obligations and make decisions with clearer financial information.
CBM Accounting helps UK ecommerce sellers keep bookkeeping, VAT and tax aligned with online trading
Ecommerce is not a side issue in the UK economy. Official ONS data shows internet sales accounted for 27.5% of total retail sales in 2025, which means online sellers are operating in a market where digital transactions, fulfilment costs and tax compliance are central to day-to-day finance.
CBM Accounting provides accounting and bookkeeping, VAT registration and filing, self assessment and tax returns, payroll, financial reporting, annual accounts and outsourced finance support for ecommerce businesses. That gives you one place to manage the numbers behind online marketplace sales, direct-to-customer orders and the HMRC deadlines that sit behind them.
“CBM Accounting brings 20+ years of experience to bookkeeping, VAT and tax support for UK ecommerce sellers.”
If you sell through an online marketplace, your own website, or both, we help you keep records that reflect how your sales are actually made. That matters when fees, refunds, shipping charges and marketplace-led VAT treatments can affect both your bookkeeping and your reporting position.
CBM Accounting’s ecommerce accounting support can include:
- Bookkeeping for online sales activity and digital record keeping
- VAT registration, VAT returns and VAT advisory
- Self assessment tax returns and corporation tax support
- Annual accounts and financial reporting
- Payroll services for ecommerce teams
- HMRC and Companies House compliance support
- Outsourced accounting and back-office support
- Tax investigation support where extra HMRC attention needs careful handling
VAT, Making Tax Digital and HMRC compliance for marketplace and direct-to-customer ecommerce
VAT is often where online sellers lose the most time. CBM Accounting helps you build a workable process for marketplace transactions, direct-to-customer sales and cross-border activity, including records that may need to reflect OSS/IOSS-related rules or other ecommerce VAT treatments.
We also help you stay ready for Making Tax Digital. HMRC’s first phase began for businesses registered for VAT in April 2019, and Making Tax Digital for Income Tax is being extended in stages from April 2026, so digital record keeping is becoming more important for ecommerce sole traders as well as companies.
“From its London office at 86-90 Paul Street, EC2A 4NE, CBM Accounting serves ecommerce businesses across the UK.”
When you are unsure which transactions need VAT attention, what records should be retained, or how marketplace and direct sales should be separated, CBM Accounting turns the rules into a practical bookkeeping and filing process. That reduces the risk of inaccurate returns and makes HMRC queries easier to deal with if they arise.
Cloud accounting and outsourced finance support for growing online retailers
Accurate annual accounts matter, but ecommerce businesses usually need visibility long before year end. CBM Accounting uses cloud accounting and digital tools to keep sales, costs, VAT and liabilities visible during the year, which helps you plan cash flow, review margins and spot issues earlier.
If your business has moved beyond basic bookkeeping, we can add outsourced accounting and back-office support so your finance admin does not slow down growth. CBM Accounting can also handle payroll, financial reporting and compliance work in one joined-up service, so you do not have to manage separate providers for each task.
“Established in 2010, CBM Accounting has supported 1,000+ clients with accounting, tax, payroll and compliance.”
Our support is tailored to your structure, filing needs and sales model. That means a sole trader preparing for Making Tax Digital needs a different setup from a VAT-registered ecommerce company with staff, regular returns and year-end reporting, and we scope the work around those real differences rather than using a one-size-fits-all package.
Why CBM Accounting is a strong ecommerce accountant for UK sellers
CBM Accounting is a chartered accountancy and tax consultancy firm with over 20 years of experience across accounting, tax, payroll and compliance. For ecommerce sellers, that breadth matters because the same business often needs bookkeeping, VAT support, tax returns, annual accounts and HMRC compliance handled together rather than as isolated tasks.
CBM Accounting is also built around proactive advice, not just filing. You still need accurate submissions, but you also need an accountant who can explain what your numbers are showing, where your reporting risks sit and what needs attention before deadlines become problems.
For sellers with international exposure, CBM Accounting’s UK and UAE expertise can be especially useful where business structures, supply chains or ownership links cross borders. Our professional affiliations with ACCA, CIMA, IFA and ICPA support the standards behind our work, while our consultation style stays practical and confidential.
CBM Accounting is often the right ecommerce accountant for you if:
- You sell through an online marketplace, direct to customers, or both
- You need regular bookkeeping and VAT support rather than year-end help alone
- You want cloud accounting and digital records that support Making Tax Digital requirements
- You need one firm to handle tax, payroll, compliance and reporting together
- You want a London-based accountant with across the UK service and experience supporting SMEs, startups and sole traders
