Toss Files Complaint Against Naver Over POS Integration Dispute

Toss has filed a complaint against Naver with the Fair Trade Commission, alleging unfair trade practices. The complaint claims that Naver has excluded Toss's point-of-sale (POS) system from its PlacePlus service, which connects POS data to Naver's search and map services. This dispute marks an escalation in the ongoing conflict between Toss and Naver, which began over reward marketing issues.

On November 2, Toss's subsidiary Toss Place submitted a report to the Fair Trade Commission regarding Naver's alleged abuse of its dominant market position and unfair trade practices. The commission is currently reviewing the complaint submitted through its regional offices.

The specific target of Toss Place's complaint is Naver's PlacePlus service, which provides users with information about popular menu items and other store details by integrating order and payment data recorded by POS systems. As of late August, Naver supports integration with 15 POS systems, but Toss is not among them.

Toss claims it requested data integration with Naver starting in July 2024, but Naver has not accepted these requests. A Toss Place representative stated that the complaint seeks to determine whether there was unfair discrimination in the exclusion of Toss's POS from Naver's store information service.

The representative added, "We believe that the exclusion of specific service providers from integration can impact the service choices and convenience for small business owners." They expressed hope for a fair assessment of the relevant facts and integration standards and stated that they would cooperate fully with the Fair Trade Commission's review process.

In contrast, Naver maintains that it has not intentionally excluded any specific service providers and selects integration targets based on internal criteria. Naver emphasized that the integration of PlacePlus with POS systems began in June of last year, disputing Toss Place's claim that it has been excluded for over two years.

A Naver representative stated, "The PlacePlus service began beta testing in June 2025, and we have been gradually expanding POS integration. There has been no intention to exclude or disadvantage any specific company during this process." They also noted that they are unaware of the complaint filed with the Fair Trade Commission but are prepared to clarify the facts and demonstrate compliance with the law if the process proceeds.

Previously, Toss and Naver had been in conflict over reward marketing issues, which involved Toss offering points to users who completed tasks such as searching for advertisers. Naver raised concerns that incentivizing searches could distort search results. Following this controversy, Toss decided to end its reward marketing linked to Naver searches last month.
