NetSuite SuiteScript: Customisation Guide for Indian Teams

NetSuite SuiteScript is the JavaScript-based programming language used to customise NetSuite. For Indian implementation teams, SuiteScript is how you build custom workflows, automated processes, and integrations that go beyond what NetSuite’s point-and-click configuration offers.

SuiteScript 2.x Overview

SuiteScript 2.x is the current version, built on an AMD (Asynchronous Module Definition) pattern using JavaScript ES5. It provides modules for interacting with NetSuite records, searches, workflows, files, emails, and external systems. Scripts run on NetSuite’s server side, not in the browser.

Types of SuiteScript

A Simple User Event Script Example

This script automatically sets the memo field on a sales order when it is saved:

define(['N/record'], function(record) {
    function beforeSubmit(context) {
        var so = context.newRecord;
        var customer = so.getText({fieldId: 'entity'});
        so.setValue({fieldId: 'memo',
            value: 'Order for ' + customer});
    }
    return {beforeSubmit: beforeSubmit};
});

SuiteScript for Indian Customisations

Common SuiteScript use cases for Indian businesses:

• Auto-calculate TDS on vendor bills based on section and PAN status
• Generate custom GST reports that match your CA’s format
• Integrate with Indian payment gateways (Razorpay, CCAvenue) via RESTlets
• Sync inventory with e-commerce marketplaces (Amazon India, Flipkart)
• Create custom approval workflows for purchase orders based on Indian procurement policies

Governance and Limits

SuiteScript has a governance model that limits how many API units each script execution can consume. Scheduled scripts get 10,000 units. User event scripts get 1,000 units. A single record load costs 10 units, a search costs 10, and a record save costs 20. Plan your scripts to stay within these limits, especially for batch operations.
