How this guide is reviewed

FindAccountants.uk guides are reviewed for practical accountant-comparison usefulness, source quality, internal service-page alignment, and clear warnings where tax rules or thresholds may change. Where a guide discusses HMRC, tax, VAT, payroll, or company compliance, it links to official GOV.UK or HMRC resources so readers can verify current rules before making decisions.

Do not start from net payouts

Marketplace payouts often combine sales, fees, refunds, shipping, reserves, advertising, and adjustments. If the accountant only works from bank deposits, sales and costs can be misclassified or missed.

Prepare platform reports before comparing firms so you can ask how each accountant reconciles gross sales, marketplace fees, VAT codes, and payment processor deposits.

What should marketplace sellers prepare before choosing an ecommerce accountant?

Marketplace sellers should prepare platform sales reports, payout statements, payment processor exports, refund records, advertising fees, shipping costs, stock records, purchase invoices, VAT status, customer locations, and current bookkeeping software access before choosing an ecommerce accountant. The accountant needs to understand whether you sell through Amazon, eBay, Etsy, Shopify, TikTok Shop, wholesale channels, or several marketplaces at once. Ask how the firm reconciles gross sales to net payouts, separates marketplace fees, reviews VAT coding, tracks stock and cost of goods, handles multi-currency transactions, and connects tools such as Xero, QuickBooks, Sage, FreeAgent, A2X, Dext, or other connectors. You should also confirm who checks data quality, who monitors filing deadlines, and how year-end accounts will be supported. Before appointing anyone, check current GOV.UK guidance and agree scope, software access, responsibilities, and review frequency in writing.

Check software workflow fit

Good ecommerce accounting depends on the workflow between marketplace data, payment processors, bookkeeping software, receipt tools, inventory records, and VAT submissions. Ask which integrations the accountant regularly reviews rather than which software names appear on a profile.

If the business has high transaction volume, ask how exceptions, duplicates, refunds, chargebacks, stock movements, and month-end cut-offs are checked.

Ask where VAT and bookkeeping overlap

Ecommerce sellers often need VAT and bookkeeping advice together. A VAT accountant may explain registration and return treatment, while an ecommerce bookkeeper may keep marketplace data clean enough for the VAT return and accounts.

If one firm handles both, confirm whether VAT review is included or whether specialist VAT advice is charged separately for imports, overseas sales, mixed rates, or platform-specific issues.
