What are some recommendations for affordable accounting offices in Bangkok for a BOI-certified software company?

Plenty of fraudsters in Thailand who hold themselves out as qualified accountants, lawyers, etc. Even foreign fraudsters holding themselves to be in professions that simply do not exist in Thailand, like real estate brokers and agents. The fraudsters come to Thailand because of these gaps. Its a magnet for charlatans. Hire someone in a reputable firm who works with a licensed Thai colleague (if there is one) who is licensed and qualified in his or her home jurisdiction. This is the model the larger firms use. If he or she engages in fraud, you will have some recourses. Little or no recourse with local parties.

I suggest most people here know where Bangkok is, without the need to add “Thailand” 😉

I can recommend someone to help with the BOI application process, but not the accounting part.

Also doubtful your application will be successful if planning 4 staff, BOI expect more than that normally.

I have personally had BOI on 2 of my own companies and assisted on a dozen applications.

Being that accounting is a restricted occupation, for Thais only, you need one for more than just dealing with the BOI. A licensed accountant has to sign off on lots of regular government filings. My wife is a licensed accountant. What is your budget?

Maybe read the BOI guidelines first, I don’t think small companies apply. The investment I think was very high last time I checked. Small companies can’t apply for BOI, or at least it is my understanding.
