Acumon Chartered Accountants·10 min read
Selling on Amazon creates accounting requirements that differ from many traditional businesses. Marketplace settlements, FBA fees, inventory costs, VAT obligations and international transactions all need to be recorded correctly to understand true profitability.
This guide highlights a selection of accountants for Amazon sellers in London and nearby markets. The companies covered vary in their approach, from ecommerce-focused accounting practices to broader firms offering tax, bookkeeping and business advisory services.
Acumon
Acumon is a UK firm of chartered accountants providing accounting services for Amazon sellers and ecommerce businesses. The firm supports online retailers with financial processes connected to marketplace sales, including bookkeeping, VAT compliance, management reporting and the preparation of accurate financial records.
The firm works with ecommerce businesses ranging from growing Amazon sellers and owner-managed companies to more established online retailers managing complex sales operations. Its accounting approach considers the specific requirements of marketplace businesses, including Amazon settlement reconciliation, inventory tracking, sales reporting and the need to understand true margins.
Acumon holds a Public Interest Entity (PIE) audit licence, allowing the firm to audit listed companies and other entities subject to enhanced regulatory oversight in the United Kingdom. PIE audits are subject to additional regulatory supervision and quality requirements, and only a limited number of firms are authorised to undertake this type of work.
In addition to its UK audit registration, Acumon also holds audit licences in several international financial centres, including the Cayman Islands, British Virgin Islands (BVI), Jersey, and Isle of Man. These licences enable the firm to support international corporate groups where entities are located across multiple jurisdictions.
Amazon sellers often operate across multiple sales channels and may face additional accounting challenges related to international transactions, stock movements, platform fees and VAT obligations. Managing these areas requires structured financial processes and familiarity with ecommerce business models.
Acumon works with Amazon sellers and finance teams to support day-to-day accounting requirements while helping businesses improve financial visibility, reporting accuracy and decision-making as their ecommerce operations develop.

Conclusion
Amazon sellers often need accounting support that goes beyond recording sales and expenses. Marketplace settlements, inventory values, VAT rules and advertising costs can make it difficult to understand actual profitability without processes designed around ecommerce operations.
The firms included in this guide take different approaches. Some focus heavily on Amazon and ecommerce accounting, while others provide broader accountancy services that can support online businesses as they grow. The right fit depends on the seller’s business model, sales channels, reporting needs and level of accounting support required.
