Ensure the management is run according to strata title act.

Preferably pppoint professional manager to run it so that everything done is according to the act, although committee members can run themselves, but it is not preferred, due to potential conflict of interest.

You don't need specific software, just ordinary accounting software will be enough to do the bookeeping matter.
While Manager and office clerk run the daily routine show.

Ensure every documentation and financial situation is in check, and every meeting is minuted, to avoid potential any dispute in the future.

Run it transparently and having good communication channel with residents and owners, that may minimise any potential dispute in the property management.
