The complaint, submitted to the Korea Fair Trade Commission on Monday afternoon through one of its regional offices, alleges that Naver abused its dominant market position and engaged in unfair trade practices.
The commission is reviewing the filing.
Naver launched Place Plus in June 2025. The service feeds order and payment data from merchants' point of sales (POS) terminals into Naver's search and map results, showing users popular dishes and busy hours.
Toss POS, which Toss Place says runs in about 150,000 stores, is missing from the 15 systems the service supports.
Toss Place says it first proposed a data link to Naver in July 2024 and has asked for talks several times since, without success. Naver rejected the charge of discrimination and said it is adding POS providers step by step under objective criteria that apply to all of them.
Toss Place Chief Executive Choi Jae-ho told an Oct. 12 parliamentary audit of the regulator that Naver had given no clear criteria or explanation in two years.
"We will closely examine whether Naver favored its own services and unfairly discriminated against competitors," Fair Trade Commission Chairman Ju Biung-ghi told lawmakers.
The two companies are also fighting over Toss' reward missions, which pay users points for running searches on Naver that advertisers assign.
Naver says the scheme distorts its results and asked police in February to investigate. Toss said last month it would drop only the missions linked to Naver.
