SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents incorrect or premature OSS marking of invoices by verifying country-specific OSS eligibility before the invoice is finalized, reducing tax compliance errors and rework.

Core Features & Use Cases

  • Server-side OSS validation: Requests the Fakturownia API to validate OSS conditions based on seller and buyer country data before marking an invoice as OSS.
  • CLI integration for automation: Works with the fakturownia CLI invoice create flow using identify-oss and use_oss flags to enable deterministic, scriptable invoice creation.
  • Use Case: Ideal for cross-border EU sales automation where VAT treatment must be validated programmatically to avoid misreporting.

Quick Start

Create an invoice for a cross-border EU sale and ask the CLI to validate OSS eligibility before marking the invoice as OSS.
