Accountants for E-Commerce Brands

Accountants for E-Commerce Brands

Specialist accounting for UK online retailers — Amazon, eBay, Etsy, Shopify and beyond.

Accounting Built for Online Retail

E-commerce accounting is more complex than most accountants realise. Multi-channel sales, marketplace fees, stock valuation, international VAT — it adds up fast. At Magnum Accountancy, we work exclusively with growing UK businesses, including online retailers who need an accountant that understands how Shopify, Amazon Seller Central and eBay payouts actually work.

VAT and marketplace accounting for e-commerce

VAT & Marketplace Accounting

Selling across Amazon, eBay, Etsy and Shopify creates a tangle of VAT obligations — domestic thresholds, overseas seller rules, and platform-level tax collection. We help you register at the right time, account for marketplace VAT correctly, and stay compliant without overpaying. If you sell into the EU or US we can guide you through OSS, IOSS and state sales tax considerations too.

Stock & Inventory Valuation

Incorrect stock valuation is one of the most common causes of e-commerce businesses paying too much tax — or getting their accounts rejected at Companies House. We work with you to apply the right costing method (FIFO, weighted average or specific identification), account for fulfilment centre stock held with Amazon FBA, and handle year-end stock counts and write-downs properly.

Annual accounts and corporation tax for e-commerce

Annual Accounts & Corporation Tax

We prepare your statutory accounts and CT600 corporation tax return, making sure all allowable deductions are claimed — from platform fees and packaging to storage costs and marketing spend. We file on time with Companies House and HMRC, and we flag reliefs you may be missing, including R&D tax credits if you’ve developed your own software, tools or processes.

Cash Flow & Working Capital

Online retail is cash-hungry — stock orders, shipping costs and marketplace payout delays can squeeze you even when sales are strong. We build cash flow forecasts that account for seasonal peaks, supplier payment terms and platform holding periods. Whether you’re planning a big product launch or navigating a slow quarter, you’ll always know where you stand.

Payroll for e-commerce businesses UK

Payroll & Employer Obligations

Whether you employ warehouse staff, customer service team members or part-time pickers and packers, we run your payroll accurately and on time. We handle PAYE submissions to HMRC, National Insurance calculations, auto-enrolment pension duties and statutory pay — so you stay compliant as your team grows.

Profit Extraction & Director Pay

If you run your e-commerce store through a limited company, how you pay yourself matters enormously. We model the optimal salary and dividend mix for your circumstances, taking into account your personal tax position, retained profits and future investment plans. The goal is always to keep more of what you’ve earned — legally and efficiently.
