How relevant is this direction for accounting now? I need a quality service or a qualified accountant for remote paperwork. Any ideas?

There are several international accounting services that operate in Singapore. I like this option - https://osome.com/sg/incorporation/ You can choose your option from the list of services or sign a full support contract. It was difficult for me to start a business in Singapore, although it was just an online store first. This country has its own specifics and you will need to get used to these features.
