About Ecommerce
Accounting People Also Ask
Why do I need a specialist ecommerce accountant?
Traditional accounting firms often struggle with the technicalities of digital platforms, which can lead to double counting income or missing deductible marketplace fees. A specialist understands the unique bi-weekly payout cycles and API integrations like A2X or Link My Books required to ensure your records match your bank deposits exactly.
Do I need an ecommerce accountant if I only sell on one platform like Shopify?
Yes. Shopify tracks sales and payments, but it does not manage your HMRC tax returns, payroll, or business expense deductions. We ensure your data flows correctly into your accounting software to maintain Making Tax Digital (MTD) compliance and help you understand your true net profit.
How do you handle high volume sales reconciliation?
Automation is key. We use data connectors to group thousands of individual transactions into clean, daily or weekly journal entries in Xero or QuickBooks. This prevents software slowdown and ensures every penny from gross sales to merchant fees is accounted for.
Can you help with international VAT, OSS and IOSS?
Absolutely. We manage One Stop Shop and Import One Stop Shop filings for sellers expanding into the EU. We also advise on Nexus thresholds for US Sales Tax to ensure your international growth is compliant.
How do you help online sellers save on taxes?
Beyond bookkeeping. We look for specialist opportunities such as R&D Tax Credits for custom software, capital allowances on warehouse equipment and optimised salary vs. dividend structures for directors.
Will an ecommerce accountant help me understand my Cost of Goods Sold (COGS)?
Yes. Accurate inventory valuation is critical. We help you track true COGS by factoring in landed costs, customs duties, and storage fees, giving you a real-time view of your SKU-level profitability.
