EU VAT OSS documentation
Everything you need to know about EU VAT OSS – One Stop Shop for WooCommerce.
Getting started
Install and configure the plugin
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.
