An ecommerce accountant handles VAT on your online sales (including the One-Stop Shop, OSS, if you sell to consumers in other EU countries), bookkeeping, and the reconciliation of income arriving from your store, payment gateways and marketplaces such as Amazon.

What makes ecommerce different
- Sales to several countries. Above €10,000 per year of sales to consumers in other EU countries, destination-country VAT applies. See EU ecommerce VAT.
- Many channels. Your store, marketplaces and gateways produce different reports that must match.
- Stock in other countries. It may require local VAT registration, which OSS does not replace.
- Returns and fees. They affect the VAT base and the books.
What an ecommerce accountant should include
- National VAT returns and OSS.
- Bookkeeping with gateway and marketplace reconciliation.
- VAT registrations in other countries when you hold stock.
- Handling tax authority requests.
- Advice on structure: sole trader, company, Estonian OÜ or LLC.
FAQ
Can one accountant cover Amazon and my own store? Yes, if they can reconcile both channels; ask about their experience.
How much does it cost? It depends on countries, volume and structure; ask for a breakdown of what the fee includes.
