Expert E-commerce Accountants for UK Online Sellers, Shopify & Amazon Stores

E-commerce accountants helping a UK online seller pack and manage Shopify and Amazon orders
July 15, 2026

Expert e-commerce accountants can make or break how smoothly your Shopify store or Amazon FBA business runs behind the scenes. Multi currency payouts, platform fees and confusing VAT rules pile up fast once you sell online, and generic accountants often do not know where to look. NS Accounting works daily with UK online sellers, solving the specific, global headaches that come with running a modern e-commerce business, from cross border VAT to Shopify payout reconciliation and Amazon FBA landing fees. That is exactly the specialism our e-commerce accountants bring to every online seller we support.

Why UK Online Sellers Need Specialist E-commerce Accountants

Traditional accountants are trained to handle straightforward UK businesses with one bank account and predictable invoices. E-commerce is different. Your Shopify store might take payments through Shopify Payments, PayPal and Stripe at the same time. Your Amazon account might sell across several European marketplaces, get paid in different currencies, and hold stock in FBA warehouses across borders. Without an accountant who understands these platforms in detail, it is easy to misreport income, miss VAT deadlines or lose track of your true profit margin.

That is where NS Accounting comes in. As dedicated e-commerce accountants, we work daily with Shopify, Amazon, eBay and Etsy sellers, so we already understand your reports, fee structures and reconciliation challenges before we even open your books.

We Handle the Global E-commerce Headaches You Are Tired Of

Selling online should not mean spending your evenings untangling spreadsheets. Here are three of the most common, and most stressful, problems we solve for our clients every day.

Cross Border VAT for Shopify and Amazon Sellers

Once you start selling to customers outside the UK, VAT gets complicated fast. You may need to register for the EU One Stop Shop or Import One Stop Shop scheme, track different VAT thresholds in each country, and manage Amazon Pan European FBA stock movements, all while keeping your UK VAT return accurate too. Get this wrong and you risk penalties, blocked funds or an unexpected tax bill. You can review current thresholds directly on GOV.UK, though most sellers prefer to leave this to a specialist.

Our team manages VAT registration, cross border compliance and ongoing returns for online sellers trading across the UK, EU and beyond, so nothing slips through the cracks. This is one of the areas where specialist e-commerce accountants add the most value early on. Learn more about our dedicated VAT services for online businesses.

Shopify Payout Reconciliation Made Simple

Shopify payouts rarely match your sales reports exactly. Fees, refunds, chargebacks, currency conversions and multiple payment gateways such as Shopify Payments, PayPal and Stripe all affect what actually lands in your bank account. Trying to reconcile this manually every month, using Shopify’s own payout reports, is one of the biggest time drains for online sellers.

We connect your store to clean, automated bookkeeping systems, matching every payout back to the correct sales, fees and refunds, so your accounts are always accurate and ready for review. This sits at the core of our specialist bookkeeping service for e-commerce businesses.

Amazon FBA Landing Fees and True Product Costs

Amazon FBA fees are notoriously hard to track. Referral fees, fulfilment fees, storage fees, long term storage charges and returns processing costs, all listed on Amazon’s own seller pricing page, can quietly eat into your margin. On top of that, landing costs such as freight, import duty and customs charges need to be added to your true cost of goods sold, otherwise your reported profit will be wrong.

We build clear, accurate landed cost models for every product line, so you always know your real margin, not just the number Amazon shows you. This feeds directly into the planning we provide through our specialist tax advice service.

Cross border VAT, Shopify reconciliation and Amazon FBA fees are only part of the picture. As experienced e-commerce accountants, we also support every other financial need your business has as it grows. Our services for e-commerce businesses include:

Frequently Asked Questions

E-commerce accountants go beyond basic bookkeeping. They reconcile Shopify and Amazon payouts, manage cross border VAT, track true product costs including FBA and landing fees, and prepare accurate accounts that reflect how a modern online store actually operates.

Depending on where your customers are based, you may need UK VAT registration, EU One Stop Shop registration, or Import One Stop Shop registration. Amazon Pan European FBA can also create VAT obligations in several countries at once, which is why specialist support matters.

Shopify payout reconciliation means matching the money that actually lands in your bank account against your sales, refunds, chargebacks and processing fees. Without it, your reported revenue and profit can be significantly wrong, which affects both tax filings and business decisions.

FBA fulfilment fees, storage charges and referral fees reduce your margin on every sale, while freight and import duty increase your true cost of goods sold. If these are not tracked accurately, your profit figures and tax position will not reflect reality.

Yes. Selling across Shopify, Amazon, eBay and Etsy at the same time means juggling different fee structures, payout schedules and currencies. A specialist e-commerce accountant consolidates all of this into one accurate, unified set of accounts.

Costs vary depending on order volume, number of sales channels and whether you need VAT registration in multiple countries. NS Accounting offers clear, fixed fee packages, so you always know what you are paying with no hidden extras.
