Hello, we are Quartile.
Quartile is an Odoo partner that supports Odoo implementations in Japan and around the world.
We deliver our services almost fully remotely, leveraging OSS effectively to maximize cost efficiency.
Experts in the Odoo Lifecycle
Implementing Odoo requires not only system knowledge and business expertise, but also a deep understanding of Odoo’s concepts and specifications—making it difficult to cover everything in-house.
Since 2013, Quartile has been among the earliest in Asia to work with Odoo, building extensive experience to support implementations at optimal cost. Whether Odoo is the right fit for your business and how it can streamline your operations can be difficult to determine. By working with Quartile, you can implement Odoo faster and more cost-effectively than by trial and error on your own.
Leveraging the expertise we’ve built through past version upgrade projects, we deliver the right framework for smooth implementation and operations.

Delivering Value through OSS Contributions
At Quartile, we are committed to advancing OSS community contributions, including improvements to the Odoo core, Japanese localization, and functional proposals and reviews within the Odoo Community Association (OCA).
To truly leverage OSS, participation in community activities is essential. However, the technical hurdles of the OCA’s code review and adoption process, as well as language barriers, have made it difficult for Odoo service providers in Asia to participate in OSS activities.
Through continuous engagement in OSS, we not only enhance the quality of Odoo itself but also integrate community feedback into our services, ensuring our clients gain maximum benefit.
Extensive Track Record in Japan and Overseas
Introducing an ERP system that deeply integrates with daily business operations requires proper adaptation to the laws and business practices of each country.
Founded in Hong Kong and with proven expertise across Japan and global markets, Quartile provides region-specific Odoo implementation strategies and resolves operational challenges quickly and effectively.
We also support Odoo implementations in English, from full project delivery to ongoing maintenance.


Fully Remote and Agile
Since launching our Odoo services in 2013, Quartile has maintained an agile approach while utilizing online communication tools to provide services primarily on a fully remote basis.*
This approach eliminates the need to coordinate meeting locations or spend time on member travel, allowing us to concentrate on the work that truly creates value.
*For customers in the manufacturing industry, we may visit on-site when necessary to better understand the operational environment.

Our Mission and Values
Creating Value
We base our value judgments on three markets: customers, teams, and the ecosystem in which business exists. We act to concretely and fundamentally solve the challenges in each of these markets. To achieve this, we continually ask “why,” aim for true purpose, and strive to improve our practices.
Being Fair
We are committed to fairness in our relationships with customers and team members. When differences in interpretation arise, we clarify the facts and take appropriate actions based on business integrity and social norms. By doing so, we ensure that stakeholders share a common ground for creating value.
Being Open
We share information openly with team members, the OSS community, and our customers. Openness reinforces fairness. We reject hidden inequities and prioritize trust and transparency above all else.
