Heather Bennett

NetSuite, a popular cloud-based business management software, utilizes a powerful scripting language known as SuiteScript. SuiteScript is an integral part of the NetSuite platform, allowing developers to customize and extend the functionality of their NetSuite account.

What is SuiteScript?

SuiteScript is a server-side JavaScript-based scripting language developed by NetSuite. It provides developers with a comprehensive set of APIs (Application Programming Interfaces) to interact with the NetSuite platform and build custom business logic, workflows, and integrations.

Why Use SuiteScript?

SuiteScript offers several benefits:

  • Flexibility: With SuiteScript, you can tailor NetSuite according to your unique business requirements. It allows you to create custom workflows, automate processes, and integrate with external systems.
  • Efficiency: By leveraging SuiteScript’s capabilities, you can automate repetitive tasks and streamline your business operations.

    This helps improve efficiency and productivity in your organization.

  • Scalability: SuiteScript supports businesses of all sizes. Whether you are a small startup or a large enterprise, you can utilize SuiteScript to scale your operations as your business grows.

SuiteScript Features

SuiteScript offers various features that enhance its functionality:

1. Server-Side Execution

SuiteScript is primarily designed for server-side execution. This means that scripts written in SuiteScript run directly on the server rather than on the client’s browser. Server-side execution ensures data security and reduces the processing load on client devices.

2. Object-Oriented Programming (OOP)

SuiteScript follows the principles of Object-Oriented Programming (OOP). It provides a wide range of built-in objects and functions that can be used to manipulate and interact with NetSuite records, transactions, and other entities. This allows developers to write clean and organized code.

3. Event-Driven Architecture

SuiteScript follows an event-driven architecture. It allows developers to define scripts that are triggered by specific events or actions within NetSuite. For example, you can create a script that runs whenever a new sales order is created or when a customer record is updated.

4. SuiteScript APIs

SuiteScript provides a comprehensive set of APIs that enable developers to interact with NetSuite’s core functionalities. These APIs cover areas such as record manipulation, search operations, workflow management, file handling, email communication, and more.

SuiteScript Versions

NetSuite offers two versions of SuiteScript:

1. SuiteScript 1.0

SuiteScript 1.0 is the older version of SuiteScript and is based on JavaScript 1.5. It uses script records and custom records for customization purposes.

  • Advantages: SuiteScript 1.0 has been around for a long time and has extensive documentation and resources available online.
  • Disadvantages: SuiteScript 1.0 has some limitations in terms of performance and flexibility compared to SuiteScript 2.0.

2. SuiteScript 2.0

SuiteScript 2.0 is the latest version of SuiteScript introduced by NetSuite in 2015. It is based on ECMAScript 5 (JavaScript 1.8.5) and provides enhanced performance, modularity, and improved error handling capabilities.

  • Advantages: SuiteScript 2.0 offers better performance and more advanced features compared to SuiteScript 1. It also follows modern JavaScript standards.
  • Disadvantages: As SuiteScript 2.0 is relatively new, it has fewer online resources and documentation compared to SuiteScript 1.


In conclusion, NetSuite utilizes the powerful scripting language called SuiteScript for customizing and extending its functionality. With its flexibility, efficiency, scalability, and various features such as server-side execution, object-oriented programming, event-driven architecture, and comprehensive APIs, SuiteScript empowers developers to create tailor-made solutions for their businesses. Whether you choose SuiteScript 1.0 or the newer SuiteScript 2.0 depends on your specific requirements and preferences.
