FAQs on ecommerce accounting

When do I need to register for VAT as an online seller?

You must register for VAT once your taxable turnover passes £90,000 in any rolling 12-month period. Many ecommerce sellers register voluntarily before that, to reclaim VAT on stock and costs. Cross-border and marketplace sales can complicate when and where VAT applies, so it pays to check early. Our guide to VAT thresholds and registration explains the rules in full.

How is VAT handled on sales to the EU and overseas customers?

It depends on where your customer is and what you sell. Sales to EU consumers may fall under the Import One-Stop Shop or OSS rules, while goods sold into the UK from abroad have their own treatment. Getting this wrong risks under-reporting and penalties. Our guide to VAT on imports and exports breaks down how cross-border VAT works for sellers.

Why can't I just use a regular high-street accountant?

You can, but most generalists are not set up for ecommerce. Online selling involves platform fees, payout reconciliation, multi-currency sales and inventory-based cost of goods, which traditional accounting often handles poorly. A specialist records what you actually earn after fees and refunds, keeping your accounts accurate and HMRC-ready. That accuracy protects your margins and reduces the risk of costly filing errors.

What accounting software is best for ecommerce sellers?

Most ecommerce sellers use Xero, paired with our in-house software SleekBooks, because it integrates cleanly with platforms like Amazon, Shopify and Etsy. The right setup pulls your sales data in automatically, reducing manual entry and reconciliation errors. At Sleek you get the software plus a real accountant checking everything is accurate, compliant and tax-efficient, rather than software alone doing the work.

How does a specialist help with platform fees and payouts?

Your Shopify or Amazon payout is rarely the same as your sales total. Platform fees, payment-processor charges, refunds and chargebacks all reduce it. A specialist reconciles each payout against your actual sales, so your books show true revenue and profit, not just order value. This gives you accurate margins to price confidently and avoids nasty surprises when your accounts are finalised.

Do Amazon sellers need a specialist VAT accountant?

Amazon sellers in the UK benefit significantly from working with a specialist VAT accountant rather than a generalist. Selling on Amazon involves VAT complexities that most standard accountants are not set up for: marketplace facilitator rules, FBA storage in multiple countries, OSS and IOSS obligations for EU sales, and payout reconciliation across currencies. An ecommerce VAT accountant ensures your returns reflect what you actually earned after fees and refunds, and that your cross-border obligations are met before HMRC flags them.

Do I need to track inventory differently for tax?

Yes. If you hold stock, your cost of goods sold must reflect inventory accurately, which directly affects your taxable profit. Sellers using FBA, dropshipping or 3PL face added complexity around landed costs and stock valuation. A specialist ecommerce accountant records these correctly, so your profit figures and Corporation Tax are right. Our guide to limited company expenses covers what else you can claim.
