Which is more customisable?

NetSuite offers significantly more customisation flexibility:

• A configurable interface to easily create fields and custom records with no coding
• Standard report write within netsuite that allows users to build their own
• SuiteFlow for workflow automation
• SuiteTalk for API integrations
• SuiteScript (JavaScript-based) for extensive customisation
• 700+ pre-built SuiteApps

MYOB Advanced provides customisation through Acumatica's framework but with a smaller ecosystem and more limited options.
