Audit services for e-commerce businesses
E-commerce businesses generate high transaction volumes across multiple sales channels, payment platforms, and geographies. The audit challenges are different from brick-and-mortar retail: marketplace fee accounting, multi-currency settlement, digital VAT obligations, refund and return provisions, and the reconciliation of payment platform data to accounting records all need specialist attention.
We audit e-commerce businesses selling through their own websites, Amazon, eBay, Shopify, and other marketplace platforms, from fast-growing DTC brands to established multi-channel retailers.
What is an e-commerce audit?
An e-commerce audit examines whether the financial statements accurately reflect the company’s trading position. For online retailers, the key audit areas differ from traditional retail because revenue flows through digital platforms rather than tills, and the data trail sits in payment processors, marketplace dashboards, and ecommerce platform analytics rather than a single POS system.
The audit covers financial reporting accuracy, but it also considers the commercial systems that produce the numbers. If your ecommerce platform doesn’t reconcile cleanly to your accounting software, the auditor needs to understand why and test whether the gap creates a material risk.
Key audit areas for ecommerce businesses
- Revenue recognition across channels – Revenue from direct website sales, marketplace sales, and wholesale channels may follow different recognition rules. Marketplace sales need careful treatment: is the e-commerce business the principal (recognising gross revenue) or the agent (recognising commission only)? Getting this wrong overstates or understates turnover.
- Payment platform reconciliation – Stripe, PayPal, Amazon Seller Central, and other platforms hold funds, deduct fees, and settle on different schedules. The audit reconciles platform data to the accounting system and checks that fee deductions are correctly recorded.
- Returns and refund provisions – Ecommerce businesses typically have higher return rates than physical retail, especially in fashion and consumer electronics. The audit tests whether return provisions are adequate based on historical data and the returns policy published on your product pages.
- Digital advertising spend – Marketing costs on Google Ads, Meta, TikTok, and influencer partnerships can be a significant expense line. The audit checks correct classification and period allocation of these costs, which directly affect reported profitability.
VAT on e-commerce sales
VAT for ecommerce businesses is complicated. Post-Brexit rules for selling to EU consumers, the UK one-stop-shop arrangements, and marketplace deemed supplier rules all create compliance obligations. Amazon and eBay now collect and remit VAT on behalf of sellers in many scenarios, but the seller still has reporting obligations.
Our audit considers VAT compliance as part of the overall risk assessment. If we identify potential exposure from incorrect treatment of cross-border e-commerce sales, we flag it early so you can take corrective action rather than waiting for HMRC to find it.
How ecommerce audit differs from website or SEO audit
When people search for an e-commerce audit, they sometimes mean a website performance review or an SEO audit of their online store. That is a different exercise entirely. An SEO audit reviews your ecommerce website structure, product page optimisation, site speed, and search visibility. The goal is to optimise your store so it ranks better and converts more visitors into buyers.
A financial audit examines whether the numbers in your accounts are right. It gives shareholders, lenders, and HMRC confidence that your reported revenue, costs, assets, and liabilities are materially accurate.
Both are valuable, but they serve different purposes. We provide the financial audit. If you need to optimise your ecommerce site for SEO, that is a job for a digital marketing agency. What we can tell you is whether the revenue your ecommerce website generates is correctly reflected in the financial statements.
Inventory and fulfilment
E-commerce businesses may hold stock across multiple locations: their own warehouse, Amazon FBA centres, third-party logistics providers, and supplier drop-ship arrangements. The audit verifies that inventory is correctly valued, that goods held at third-party locations are properly controlled, and that stock counts cover all locations.
For businesses using drop-shipping, the audit assesses whether the accounting treatment reflects the commercial substance (agent vs principal) and whether supplier liabilities are complete at year end.
Scaling and growth-stage issues
Many ecommerce businesses hit the audit threshold during rapid growth. The finance function often lags behind the commercial operation. We frequently see first-time audit clients with accounting systems that don’t integrate properly with their ecommerce sales platforms, incomplete reconciliations, and manual processes that cannot scale.
We help growing e-commerce businesses prepare for their first audit and build the financial infrastructure they need to support continued growth. That means getting your ecommerce data flowing cleanly into your accounting system so the audit process runs efficiently.
Product page and transaction data
Your product pages generate the sales data that feeds your financial statements. If product page pricing, discount codes, bundle offers, or subscription billing don’t match what hits the ledger, the auditor needs to investigate. We test the data flow from ecommerce platform to accounting system to make sure revenue is captured accurately.
For businesses with thousands of SKUs, we use data analytics to test entire transaction populations rather than just sampling. This catches pricing anomalies, duplicate transactions, and revenue recognition errors that sampling alone might miss.
Our approach
We understand the ecommerce ecosystem. We work with platform data exports, API-generated reports, and multi-channel selling tools. Our e-commerce audit approach is built around the specific risks that online retail creates, not a generic template adapted from traditional retail.
We are ICAEW-regulated and on the Register of Statutory Auditors. Audit fees are fixed. If you need an auditor who understands ecommerce, call us on 0161 832 4451 or request a callback.
