E-commerce Accounting for Amazon, Shopify & Online Sellers

Running an online store creates accounting challenges that go beyond ordinary bookkeeping. We help suitable UK e-commerce businesses bring sales, refunds, marketplace fees, payouts, stock costs and cash flow into a clearer financial picture.

Why it’s different

Your payout is not your profit

Marketplace fees, refunds, reserves, advertising, inventory and VAT all sit between what you sell and what reaches your bank. Without reconciling them, it is hard to know how profitable the business really is.

Payouts ≠ sales

A single settlement can combine sales, refunds, fees, reserves and adjustments. Recording only the net payout hides what actually happened.

Stock changes the picture

Profit depends on what the goods you sold actually cost, not on what you bought this month. Stock and cost of sales need recording properly.

VAT needs care

Marketplace transactions, imports and fees can each have their own VAT treatment, and getting it wrong is costly to unpick later.

Common questions

E-commerce accounting FAQs

Do you work with Amazon FBA sellers?

Yes. We can discuss settlement reconciliation, marketplace fees, refunds, inventory and management reporting for UK-based sellers, subject to reviewing the business and agreeing the scope.

Can you help with Shopify accounting?

Yes. The work may include reconciling Shopify sales, refunds, payment processor fees and payouts to your accounting records.

Can you help with e-commerce VAT?

We can help with UK VAT registration and returns and review the VAT treatment of relevant transactions. Overseas stock and cross-border VAT matters are assessed individually and may need specialist advice.

Do you provide product-level profit reports?

Where reliable product costs, sales, refunds, inventory and advertising data are available, we can discuss product or channel profitability reporting. We’ll tell you honestly if the data isn’t complete enough yet.

Which platforms and software do you support?

We work with cloud accounting software including Xero, QuickBooks and Sage. We’ll confirm which marketplaces, connectors and apps we can support for your business during the initial conversation.

How much does it cost?

Fees depend on your platforms, transaction volume, stock and reporting needs. After an initial review we confirm a fixed monthly fee and exactly what it covers, in writing, before any work starts.
