What does OSS (One-Stop Shop) mean in affiliate marketing?

OSS (One-Stop Shop) in Affiliate Marketing
The One-Stop Shop (OSS) principle in affiliate marketing refers to the centralized handling of tax and administrative processes for cross-border services within the European Union. At selecdoo, OSS simplifies VAT management for both advertisers and publishers by allowing all necessary filings and payments to be processed through a single point of contact.
For advertisers, OSS means they no longer have to declare and pay VAT separately in each EU country where they run affiliate campaigns. Instead, VAT registration and payment are handled collectively via the OSS system—greatly reducing administrative effort and ensuring compliance with legal requirements.
For publishers operating across borders, OSS streamlines the processing of their commission payments by consolidating VAT reporting and remittance. This reduces the need for multiple VAT registrations and increases transparency and legal certainty.
selecdoo uses the OSS model to meet complex tax obligations in international affiliate marketing, enabling efficient, compliant collaboration between advertisers and publishers. This significantly simplifies cross-border business in affiliate marketing.
