One of the prerequisites for establishing a business in Singapore is registering the office address there, which must be entered in the application form, submitted to, and registered with the Accounting and Corporate Regulatory Authority (ACRA).
Even though they can utilize the registered office services, registering an office address in Singapore is a need for creating a company there. Without doing so, the firm cannot be established in Singapore..
Besides that, these are two options for the owners in choosing the kind of offices to register in Singapore: Physical office and virtual office
Physical office: this is a "live" office. The owner will have the real office address located in Singapore. This office has at least one administrative personnel to attend and act on things at the office.
Virtual office: this receiving and forwarding all mail notifications and dedicating the phone lines and fax to email
