# NetSuite SuiteScript vs Custom Code

> **Definition:** SuiteScript is NetSuite's proprietary JavaScript-based scripting language for customizing ERP workflows, with strict sandboxing limitations, governance point quotas, and no access to the underlying database schema.

## In depth

SuiteScript allows NetSuite administrators to customize workflows, but within tight constraints: governance points (CPU budget per script execution) are limited, database access is restricted to NetSuite's record API (no direct SQL), and all customizations must survive NetSuite's quarterly upgrade cycles. Complex business logic frequently hits governance limits, requiring expensive SuiteScript optimizations or architectural workarounds. In contrast, custom ERP gives full PostgreSQL access with no sandboxing restrictions.

## How ERPStack applies this

We analyze SuiteScript customizations during migration discovery to understand the business logic they implement, then rebuild that logic as clean TypeScript functions in a custom Next.js ERP with unrestricted PostgreSQL access.
