FAQ

Q. Which is easier to obtain — Inno-Biz or Main-Biz?

A. For companies without R&D or patents, Main-Biz is generally more accessible. For technology-focused companies, Inno-Biz fits better. It depends on your company's profile.

Q. If I already have Inno-Biz, do I still need Main-Biz?

A. The two certifications offer different benefit ranges. For maximum procurement and financing advantages, holding both is recommended.

Q. Is there any exception to the 3-year business age rule for Main-Biz?

A. In principle, Main-Biz requires 3+ years of business history. Startups under 3 years should pursue Inno-Biz first, then apply for Main-Biz later.

A. Systematically compile your R&D investment record, patent/certification holdings, and R&D personnel data. Working with a professional will help you maximize your score without missing any criteria.
