Odoo for Japan

Localised, Compliant, Ready to Grow

SerpentCS offers a comprehensive Odoo Japan Localization solution designed to help businesses stay fully compliant with Japan’s complex financial, tax regulations, and Payroll structures. Our custom localization module supports Japan-specific requirements, effectively managing both standardized national rules and regional variances.

With pre-configured settings for National Pension, Employment Insurance, and Workers' Accident Insurance, SerpentCS enables Japanese companies to automate complex calculations. The solution seamlessly handles regional nuances-such as varying Health Insurance rates between prefectures like Tokyo and Saitama, and municipality-based Resident Tax-ensuring accurate Payroll and Tax submission with customized salary rules.
