In September 2025, OPTI Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Akatsuki Fuchigami, hereinafter "OPTI") exhibited at "Stripe Tour Tokyo 2025," hosted by Stripe, and introduced the services of Taxually — for which OPTI holds exclusive sales rights in Japan — together with OPTI's own tax technology implementation support solutions.

Background

Since its founding in 2010, OPTI has focused on tax and legal support for cross-border and global e-commerce, and now enables tax registration and filing in 90 countries worldwide. In 2024, OPTI joined Andersen Global as a collaborating firm, establishing a support framework connected to a network of professionals in more than 170 countries.

OPTI has also appeared on the business media outlet PIVOT, where it discussed the selection and development of tax technology, implementation support, and tax filing operations.

 

Challenges in Implementing Tax Technology such as Taxually, and OPTI's Support

Taxually is a technology-driven tax filing tool that can integrate with Stripe to streamline tax filing. However, users of such services commonly report challenges such as:

  • Not knowing which documents are required for tax registration, making it difficult to proceed with the process
  • Uncertainty about how to configure the settings
  • Anxiety caused by English-language explanations and unfamiliarity with the corresponding Japanese document names
  • A need for concrete tax advice tailored to their specific business challenges, ideally explained in Japanese
  • A need to identify issues beyond indirect tax, including direct tax, transfer pricing, trademarks, consumer protection, and personal data protection across global e-commerce operations
  • A need for business requirements definition, functional requirements definition, and non-functional requirements definition

OPTI addresses these challenges by combining technology with in-house tax specialists.

 

Taxually Implementation Support Package

OPTI's Taxually implementation support package provides comprehensive support, from organizing pre- and post-implementation issues to coordinating with internal stakeholders. In addition, under OPTI's white-label offering — starting from 200,000 yen per month — OPTI acts as an intermediary to handle tax filing using Taxually, allowing companies to pursue global expansion with confidence.

Integration with Stripe

Companies using Stripe can seamlessly integrate Stripe with Taxually, using their transaction data directly for efficient tax filing. OPTI maximizes this integration while coordinating with clients' finance and corporate planning departments and handling filing on their behalf, providing a framework for companies to confidently enter international markets.

Target Companies and Future Outlook

The target audience includes digital-focused companies, physical goods e-commerce businesses, and online marketplaces that are seriously considering digitalization or e-commerce expansion.

Through its partnerships with Stripe and Taxually, OPTI will continue to facilitate smoother global e-commerce expansion for Japanese companies. Beyond simple tool implementation, OPTI provides comprehensive solutions tailored to management challenges, supporting confident and reliable entry into international markets.
