The question is whether all the effort involved with setting up a company in Singapore is necessary, especially when other solutions, such as a US LLC, are significantly easier to manage. To be clear, Singapore is a great option, but in many cases, it may not be required.
Additionally, many accountants in Singapore are reluctant to work with non-resident companies. They often suggest that you operate as if you are a resident company, even if you are not. Feeling wise, I have spoken with every accountant in Singapore, and their opinions regarding non-resident companies have been quite diverse.
