Frequently asked questions

What does company formation, licensing and investment promotion cover?

Registry and licensing work that defines what a business may lawfully do in Thailand, including the routes available to foreign investors. It currently contains 5 sub-services: Company and partnership registration · Foreign business licence and certificate · BOI investment promotion application · Corporate change filings · Trademark registration.

How do I pick the right sub-service in company formation, licensing and investment promotion?

Start from "where will this be used and who reviews it?" That identifies the receiving authority, and the receiving authority — not the other way round — dictates the format of work required.

Can several services run in parallel?

Often yes, and it usually saves time because the same base documents are reused. Some pairs have a mandatory order, though — certified translation cannot precede a fully certified source document.

Where is company formation, licensing and investment promotion available?

Bangkok, Khon Kaen, Udon Thani and Nong Khai, plus online intake from every province and from overseas.

When is company and partnership registration the right choice?

Name reservation, memorandum of association, statutory meeting and registration with the Department of Business Development. A limited company suits liability limitation and fundraising; a partnership suits small ventures among highly trusting partners.

When is foreign business licence and certificate the right choice?

Assessment of whether the activity falls under restricted lists, and preparation of a foreign business licence or certificate application. The licence route fits general activities; the investment-promotion route fits qualifying activities willing to accept promotion conditions.

When is boi investment promotion application the right choice?

Eligibility assessment, application preparation and post-approval compliance for investment promotion. Unlike a foreign business licence, promotion grants investment incentives rather than mere permission to operate.

When is corporate change filings the right choice?

Filings for changes of directors, signing authority, registered address, objectives, capital and share transfers. Unlike incorporation, continuity of the existing entity must be preserved and historical filings must remain consistent.

When is trademark registration the right choice?

Similarity search, goods and services classification, and filing of a trademark application. Unlike company-name registration, a trademark protects commercial use for specified goods or services, not merely the registry entry.
