I may be bias, but Financio (https://financio.co/) is highly suitable for startup businesses / small - micro businesses. It is supported by a local team and is SST compliant.

They have a free version (limited to 10 invoices /mth) and the premium version is only RM 31.08/mth.

P.S: I am the Community Manager here at Financio, and I can assure you that the team is ready to provide necessary support.
