visit singapore 2-3 days in a week with SVP

[jimwonder]

Hi,
i'm indonesian and i holded EP before resigned, now work as a freelancer, have some clients in singapore and i need to come to Singapore every week for 2-3 days to attend meeting and consultation then go back to indonesia. I can't get any pass from all my clients because we are in short term and don't sign any contract. When i invoiced they charge 15% for tax return.
am i permitted to enter singapore in SVP with situation like this, or do i need to bring any document or confirmation letter from my client to present to ICA officer?


Thanks.
