While NetSuite customizations improve business efficiency, unmanaged scripts, workflows, and integrations can lead to long-term technical debt.
1. Common Sources of Technical Debt
Overlapping or redundant scripts
Poorly documented workflows
Excessive client-side logic
Hard-coded IDs and environment-specific paths
2. Impact
Slow system performance
Errors during upgrades
Difficulty troubleshooting or extending custom logic
3. Prevention Strategies
Maintain a Customization Register (who created, when, and why).
Use naming conventions for scripts and records.
Review scripts quarterly for unused code.
Prefer SuiteFlow or standard configuration where possible.
4. Governance & Code Review
Check governance limits in heavy scripts (use runtime module).
Implement peer review for all deployments.
Store all custom code in version control (e.g., Git).
