EU VAT OSS documentation

Everything you need to know about EU VAT OSS – One Stop Shop for WooCommerce.

Features

Core plugin features available in the free version

Threshold tracking

How the plugin builds your running total against the EUR 10,000 EU OSS threshold: what counts, how amounts are calculated, and how refunds and status changes are handled.

Order classification

How the plugin classifies WooCommerce orders as Domestic, Non-EU, EU B2B, or EU B2C, and how to see the classification on each order.

B2B VAT number field

Capture EU business customers' VAT numbers at checkout so B2B orders are correctly excluded from the OSS threshold — with format validation that never silently hides a sale.

Dashboard

The OSS dashboard: threshold progress, per-country breakdown, manual adjustments for off-platform sales, and the Recalculate tool.

Email notifications

Email alerts when your cross-border B2C sales reach the EUR 10,000 OSS threshold, and the optional follow-up when destination rates are no longer required.

Settings

Every option on the EU VAT OSS settings tab: home country, the B2B VAT-number field, notifications, and the VAT-data tools.

Filing calendar & reminders

Quarterly OSS return deadlines on the dashboard, mark-as-filed tracking, and email reminders before each deadline.

Plugin compatibility

How EU VAT OSS coexists with other VAT, checkout, and localization plugins — verified against live installs.
