Sola of America is a corporation registered in the state of Washington, USA. All contracts, purchase orders, and payments are completed entirely within the United States. As there is no need to go through our Japan headquarters, this eliminates exchange rate risk and the complexity of international remittances.

By contracting with Sola of America, a U.S.-based entity, your expenses can be processed domestically within the United States. In addition, we provide a communication framework that takes time zone differences into account, as well as in-person meetings within the U.S. when required.

We offer contract structures tailored to your needs, including fixed-price project contracts and time-and-materials engagements (such as requirements definition support, staff augmentation, and dedicated team / lab-style development). Please feel free to contact us for a consultation.

Yes. We can execute an NDA prior to any meetings if required. Please do not hesitate to let us know.

Depending on the nature of the project, engineers from both our U.S. and Japan offices collaborate on development. Primary communication with clients will be handled by the location of your choice.

Since its founding, Sola has never outsourced development to third parties. All phases of every project are handled by our in-house team of more than 200 infrastructure and software engineers, with a strong emphasis on quality and security.

Yes. While we primarily work remotely to keep costs efficient, we also provide in-person meetings and on-site support within the United States for project kickoffs and key milestones as needed.

Based on your requirements, we conduct regular meetings, provide progress reports, and manage issues and risks. We use communication tools such as Slack, Microsoft Teams, and email, adapting to your preferred tools and workflows.

Yes. All documents—including requirements specifications, design documents, and manuals—can be prepared in Japanese. We can also provide bilingual documentation in both Japanese and English.

As Sola’s primary development base is in Japan, we are able to offer services at a more reasonable cost compared to directly hiring engineers in the United States. In addition, because all development is performed in-house by our own engineers, we provide higher quality and smoother communication than typical offshore development models.

While this depends on the size and complexity of the project, we can generally provide a preliminary estimate within one to two weeks. If detailed requirements are already defined, we may be able to respond more quickly.

Yes. Please feel free to contact us regardless of project size. We will first listen to your challenges and propose the most appropriate approach.

Yes. After conducting an assessment and analysis of your existing system, we will propose an optimal maintenance and operations plan.

Yes, we can. We begin by analyzing the existing system to understand its current state and then propose an appropriate enhancement or transition plan. Even if documentation is insufficient, we can proceed through source code analysis.

Yes, absolutely. You may contact us even at the idea stage—for example, “Is something like this possible?” We can support you starting from requirements definition.

Yes. We offer ongoing operations and maintenance services after development, including incident response, feature enhancements, and system monitoring. We support our clients as a long-term development and operations partner.

We have established an information security policy and incorporate security considerations into design and implementation throughout the entire development process. When required, we can also conduct vulnerability assessments and penetration testing.

Yes. Our Japan entity, Sola K.K., is certified under ISO 9001 (Quality Management System) and ISO 27001 (Information Security Management System). These systems are continuously operated and subject to annual external audits.

In the case of fixed-price (deliverables-based) contracts, intellectual property rights to the source code and deliverables typically transfer to the client upon delivery. Details can be discussed and defined at the time of contract.
