Can I increase the paid-up capital after incorporation? How do I do so?

Yes you can. It is a fairly simple process and involves the following steps:

1. Inject additional capital into the company bank and send us a copy of the bank statement
2. We prepare the documents and circulate to obtain the signature from the appropriate parties
3. Update ACRA and get an updated company profile showing the revised paid-up capital
