You will have to communicate without problems via email or chat, exchange information and documents without necessarily having to see for yourself. This does not apply to really important and sensitive issues. Would you like to find yourself in the middle of a negotiation with a customer with the phone ringing continuously because your accountant wants to know which fax number to send you a Income Tax Filing Singapore form to sign?
You do not have to choose an accountant only on the basis of their prices. In fact, in most cases, it would be one of the worst mistakes you could make. More accurate and complex services often have higher costs.
It may be worth opting for a professional who costs a little more than another, but who, for example, can give you more attention, more services, availability, timeliness, or special advice. All these things must be put in writing, signed and countersigned.
