In e-commerce, VAT depends on customer country, stock location, marketplaces, refunds and data quality. The one-stop shop simplifies some filings, but it does not fix poor transaction classification.
OSS can centralise some VAT declarations due in other EU Member States for cross-border B2C sales.
IOSS concerns certain distance sales of low-value imported goods. It requires clear flow identification and responsibility mapping.
The calculation must be reconciled with Shopify, Amazon, Stripe, ERP, customs and accounting exports. That is often where gaps appear.
A reliable e-commerce VAT simulation starts from transaction data, not only global revenue.
We treat e-commerce VAT as a data issue: platform exports, consumption country, credit notes, refunds and bank reconciliation. An average rate is only an indicator; filing requires robust country-level data.

No. It provides an estimate. Filing must be based on country-level data, corrections and evidence.
Updated for 2026 EU rates. Results are indicative and must be reconciled with detailed country-level exports before filing.
