Hi! I work at a NetSuite partner and don't have hands-on experience with Lab Gurus specifically, but for essential oil/QC-heavy operations we usually see people either extend NetSuite's native Quality Management with custom QC record types (batch/lot testing, COA generation) or integrate a dedicated LIMS via SuiteTalk/RESTlet rather than replacing NetSuite outright. Happy to share what's worked for similar clients if that'd help your evaluation.
