The Complexity
Why Ecommerce Accounting Is Different
Online selling creates accounting challenges that standard accountants aren't equipped for. Here's what makes it complex.
Platform Fees & Reconciliation
Amazon, eBay and Etsy deduct fees, advertising costs, and fulfilment charges before paying you. Reconciling net payouts with your actual sales figures is time-consuming and error-prone without an accountant who knows how.
International VAT (OSS / IOSS)
Selling to EU customers? The One Stop Shop (OSS) and Import One Stop Shop (IOSS) schemes change how you account for VAT on cross-border sales. Get it wrong and you face penalties in multiple countries.
Inventory & Stock Accounting
Stock is an asset, not an immediate expense. Understanding how to value inventory, account for write-offs, and calculate cost of goods sold (COGS) accurately is crucial for accurate profit figures.
Multiple Payment Processors
PayPal, Stripe, Klarna, Amazon Pay — each has its own settlement schedule, fees, and reporting format. Pulling this together into clean accounts requires specialist knowledge.
VAT on Digital Services
If you sell digital products or services to consumers in the UK or EU, specific VAT rules apply depending on where your customer is located. These rules are different from physical goods.
Sole Trader or Limited Company?
When your online shop starts growing, operating as a sole trader may no longer be the most tax-efficient structure. Knowing when and how to incorporate can save significant tax.

VAT for Online Sellers
UK & International VAT — Explained
VAT for ecommerce sellers is among the most complex areas of UK tax. Here's what you need to know.
UK VAT Registration
You must register for VAT once your taxable turnover exceeds £90,000 in any rolling 12-month period. For online sellers this threshold can creep up quickly. We monitor your turnover and advise exactly when to register.
EU One Stop Shop (OSS)
If you sell physical goods to consumers in EU countries and your EU sales exceed €10,000 per year, you must account for VAT in each customer's country. The OSS scheme lets you do this through a single registration in one EU country rather than registering in each individually.
Import One Stop Shop (IOSS)
Selling goods worth up to €150 to EU consumers from the UK? IOSS lets you collect and remit EU VAT at point of sale, rather than having your customer pay import VAT on delivery. This significantly improves customer experience and conversion rates.
Distance Selling — Pre-Brexit Rules
Before Brexit, distance selling thresholds applied per country. Post-Brexit, UK sellers are treated as non-EU businesses. Sales from the UK to EU consumers are exports (zero-rated in the UK) but subject to VAT in the destination country — handled via OSS or IOSS.
VAT on Digital Services
If you sell digital products — ebooks, software, online courses, digital downloads — VAT rules differ from physical goods. In the UK, digital services are subject to VAT at the standard rate. When selling to EU consumers, VAT is charged at the rate of the customer's country.
Flat Rate VAT Scheme
Many ecommerce businesses benefit from the Flat Rate VAT Scheme — you charge VAT at 20% but pay HMRC a lower fixed percentage. Whether this is beneficial depends on your margins and the sector rate that applies to your business. We'll calculate whether it saves you money.
