Top Methods In NetSuite Integration

NetSuite is an all-in-one business management suite with ERP, a financial management system, inventory and manufacturing tools, and CRM software. NetSuite's ability to streamline operations, modernise processes, and centralise data onto a single dashboard makes it an invaluable tool for businesses of any size. For this reason, integration can be helpful for firms that want to standardise and connect their enterprise's customers, back-end processes, data, and apps.

What Is NetSuite Integration?

Netsuite is a SaaS that may streamline nearly every aspect of your business by integrating your customer relationship management (CRM), enterprise resource planning (ERP), and electronic commerce (e-commerce) systems. Instead of using separate programs for internal financial data, customer information, and e-commerce transactions, they can all be integrated into a single NetSuite dashboard.

In layman's terms, NetSuite is a robust business tool that integrates multiple pieces of software and cloud-based services into a unified system. NetSuite allows you to consolidate all of your business's accounting, customer, and e-commerce data into one location, eliminating the need for multiple programs.

While NetSuite puts a wealth of useful business information at your fingertips, you still need a solid plan and integration strategy to maximise it. Now, we will discuss the most popular methods for integrating the NetSuite platform with external, on-premise, middleware, or legacy systems, allowing for seamless data exchange and operation.

The Top 5 NetSuite Integration Resources

There are a number of approaches to go about integrating NetSuite. Here are the top integration methods and NetSuite integration platforms from which to choose for your business.


Suitelets enable programmers to make their own unique NetSuite pages and user interfaces. With suitelets, programmers may build completely unique user experiences in NetSuite. These unique pages can be built from scratch in HTML, Flash, or on NetSuite's javascript-based front-end development platform, SuiteScript. Nevertheless, SuiteTalk can only be used in tandem with a limited number of external and older applications, and SuiteTalk provides an off-the-shelf application programming interface. If you want more control over which systems you may connect to and how your dashboard looks, you may want to consider a different integration approach.

Extensions and external interfaces for applications can also be tailored with suitelets' flexible back ends. Suitelets demand a skilled developer due to the complexity of the multiple programming languages used. Suitelets do require a skilled developer to design, which can be time-consuming and expensive due to the number of different programming languages involved.

Suitelets are ideal if your firm requires more sophisticated reporting capabilities than those provided by the system by default. Suitelets are a fantastic alternative to the cumbersome default reporting that many businesses are forced to use. These come in handy if the user wants to change things like the interface's color scheme, size, or layout.


SuiteScript, NetSuite's JavaScript-like scripting language, allows robust application-scripting capabilities across the platform. Within the NetSuite ecosystem, it enables developers to craft adaptive business logic tailored to individual companies' needs. SuiteScript is a terrific place to start when customising your NetSuite integration process, but it won't give you access to every feature in the system. Although SuiteScript won't let you manage every aspect of your NetSuite account, they're a great way to personalise your experience.

SuiteScript is used by NetSuite's RESTlets and Suitelets to build critical UI components that run entirely in the cloud. SuiteScript allows programmers to do things like modify a page's functionality, set up recurring actions, and design unique workflows. Since SuiteScript is a servicer-side script that works in a request-response model, they provide you complete freedom when creating application extensions for NetSuite. SuiteScript also facilitates ad hoc testing for debugging scripts, adding to its dynamic debugging capabilities.


If you require a higher degree of customisation and integration than is provided by Suitelets, RESTlets may be a better option. SuiteScript, which is discussed in the following section, is needed for RESTlets, another sort of NetSuite script that facilitates integration. RESTlets are used by other applications to get data into the NetSuite and send secure data from the NetSuite to other apps. By the use of RESTlets, both external and internal applications can easily interact with NetSuite using the RESTful architecture. The flexibility and control that RESTlets provide set them apart from Suitetalk. With RESTlets, developers may work freely on their own processes for typical REST functions like POST, PUT and benefit from RESTlets' famed speed when interacting with data.

Like Suitelets, RESTlets requires a developer who is fluent in SuiteScript and can tailor their skills to the specific requirements of your business. Data can be transferred securely from NetSuite to other applications via RESTlets. To develop an Application Programming Interface, RESTlets are appropriate since they can be clearly developed and programmed according to specific integration needs. RESTlets, like Suitelets, need a skilled programmer who is fluent in SuiteScript and familiar with your company's unique requirements. Ideal for businesses that employ complex algorithms for data sorting or that need extensive configuration choices.


With a hand-coded integration, engineers create the full NetSuite integration from the start, making it the most flexible option because it's tailored to your company and its software. Hand-coding your NetSuite integration is the most time- and labour-intensive choice since developers must code every aspect; it also requires constant upkeep, including integrating newly onboarded tools and routine updates. Ideal for organisations that need a highly specialised version of NetSuite and have the means to invest in its constant evolution.


NetSuite offers two web service choices for integrating third-party software. Suitetalk is one of them; it's a web service communication layer that facilitates collaboration between NetSuite's ERP, CRM, and e-commerce offerings. Nevertheless, SuiteTalk only connects with a limited number of external services and older platforms. If you're hoping to tailor your NetSuite experience—both in terms of the look and feel of your dashboard and the other systems, you can connect to—you may want to look into an alternative connectivity method.

Suitetalk is not part of NetSuite and allows developers to create business objects in Java or .NET using any language or platform that supports lightweight REST-based integration. SuiteTalk can only be used in tandem with a limited number of external and older applications. This integration tool can modify, retrieve, add, and remove data in and out of NetSuite.


To identify the most effective workflow solution, companies experiment with various platforms and applications to streamline administrative tasks. NetSuite makes it easy for firms to centralise their back-office functions, giving them a cost advantage and streamlining operations. Regrettably, attempts to standardise procedures in different contexts frequently come at the expense of both effectiveness and responsibility.
