Has anyone used ACS which is the service netsuite trys to sell when your having issues with their system. I cant for the life of me wonder why anyone would pay 40k for that service.

depends on the issues, if it's truly a defect or enhancement then their is no need for ACS support. If their is a need for further support related questions or questions about using the platform then ACS could help. Also that's not the only use case, you can offload other tasks and smaller projects to them. Example: Workflows, Scripts, Forms, etc. At which point it's similar to work with a third party partner and makes a little more sense. If you just need help with training on using the platform then they offer LCS.

For an issue you should contact regular NetSuite support. ACS is mainly for advanced customization, small projects... I was candidate for a job at NetSuite ACS, and they told me "we don't solve any shit with NetSuite, that's job for NetSuite Support department" Unfortunately, I can say "Good luck with SuiteAnswers and Support" 😁
