CRM (Customer Relationship Management) apps play a crucial role in managing and improving customer relationships for businesses. There are innumerable advantages of using a CRM app for your business such as helping your business serve the customers better, increasing the customer satisfaction rate, improving the customer relationship management workflow, boosting customer retention rate, and driving word-of-mouth promotion, to name a few.

No wonder the requirement for CRM apps is spiking high and is catering to its growing market. As stated in a recent market report, the global customer relationship management market is forecast to grow at 12.5% to reach $145.79 billion by 2029 compared to its benchmark of $63.91 billion in 2022. This enormous growth scope represents the crucial role of a CRM app for your business. And no matter which sector your business operates in, it is important to opt for a CRM app or system for customer relationship management to aid in your business growth and profit.

If you have some technical knowledge or expertise, then building a React Native can be one of the best options to explore. React Native development has several advantages such as competitive product development, cross-platform compatibility, and UI and customer-driven design and approach, to name a few. And in this blog, we will give you a guide to building a React Native CRM. So let's get started!

Reasons Why Your Business Needs A Custom CRM

Before we walk you through the guide to building a React Native CRM, let’s know why your business needs a CRM, precisely a custom CRM in the first place.

Building a CRM With React

1.  Caters to a Customer-Driven Approach

To be successful, it is important for any business to take a customer-driven approach where most of your focus remains on the customer’s experience, engagement, and satisfaction level.

Opting for a custom CRM enables you to look after these factors by handling customer relationships, managing relevant workflows, and simplifying the outreach process.  As a result, you can manage the customer lifecycles, optimize them, and come up with a more customer-driven approach for your business.

2.  Offers Competitive Advantages

By opting for a custom CRM system, you can leverage several competitive advantages for your business. As such a CRM system is tailored to meet the specific customer relationship management requirements for your business, it provides a compact solution to manage and improve customer relationships as per your requirements.

Not only does it help you eliminate any possible loopholes in your present customer relationship management system but lets you optimize the whole process and KPIs to beat the competition. As per the present market, your competitors’ approaches, their audience satisfaction level, and other factors, you can leverage a custom CRM to get several competitive advantages in terms of your customer experience, engagement, retention, and others.

3.  Provides Robust Data Security

According to a recent IBM study, data breaches cause more than 4 billion loss on an average per year. Every business needs to deal with various types of customer data starting from their basic information to confidential ones.

On one hand, customer data is vital in catering to their requirements efficiently, but on the other, it increases the vulnerability of your customers’ information. Not only does it put your customers’ confidential data at risk, but affects your overall ROI. Adopting a quality CRM lets you handle the security measures and data protection metrics to safeguard them from any possible threats or breaches.

4.  Aids in Marketing

Adopting a custom CRM system improves your customers’ experience, helps your business meet their demand efficiently, and enhances customer relationship at many levels. As a result, not only do the customer lifecycle values get improved or the retention rate increase, but they aid in your business’s marketing through word-of-mouth promotion.

Benefits of React Native

As discussed before, a custom CRM system is a must-have for any business. But why should you use React Native to build it? To find the answer, we need to have a look at the key benefits of React Native.

Building a CRM With React

1.  High Reusability

One of the exclusive perks of opting for React Native is, that it facilitates high code reusability that not only cuts down the additional time or cost for deployment but simplifies the whole process. No matter which platform your app is being developed for - iOS, Android, or any other, you don’t need to write and execute separate codes.

Instead, you can reuse even more than half of the code for different platforms. This in turn optimizes the development process, helps in faster launch and delivery and reduces the hassles of maintenance or upgrading significantly.

2.  Cost-Efficient

React Native is famous among startups as well as medium to growing businesses for being cost-effective. As discussed above, the code reusability is applicable for diverse platforms and media and this ensures that you don’t need to hire platform-specific developers for your product development.

Also, React Native comes with a range of pre-built functions and components to serve different purposes during app development. As a result, you can save additional spending on coding and testing such functions.

3.  Enhanced Performance

If your goal is to develop a product, precisely a mobile app with strong performance capability, then React Native can be your choice. The same is applicable to custom CRM development.

The React Native infrastructure is highly compatible with mobile devices - both Android and iOS. By leveraging the Graphics Processing Unit (GPU) and Central Processing Unit (CPU) for the native platforms, it ensures high speed and better performance for mobile apps as well as other systems.

4.  Live Reloading

It often becomes hectic and tricky to keep track of the changes you make in your code while developing a product. You may need to modify your code to fix changes, improve certain outputs, or for testing purposes.

In all these cases it is important to ensure that the changes are incorporated during the compilation process. React Native comes with a greater advantage in this case. Its auto-live reloading feature enables you to make changes in the app loading phase or reload a specific area for compilation purposes.

How to Build A Custom CRM Using React Native

Now that you have a clear knowledge of the advantages of both custom CRM and React Native, let’s know how to build a custom CRM using React Native. Here are the steps to build a custom CRM with React Native.

1.  Research and Idea Validation

The very first step to developing a custom CRM with React Native is doing extensive research and validating your idea of developing a custom CRM app. Based on your business type, the sector you are operating in, target audience, customers, customer relationship goals, and basic requirements for customer relationship management, you need to do thorough research on your basic idea.

The goal is to come up with a specific set of requirements or solutions you are looking for in your custom CRM app. For instance, your goal can be improving the customer satisfaction or engagement rate, or boosting the retention rate, or improving the customer lifecycle value, or all of these. The target of this stage is to validate your core idea to obtain a set of well-defined features/solutions you expect from the custom CRM.

2.  Market Analysis

For building a React Native CRM, you must execute this step of market analysis where you get a realistic picture of where your CRM app stands in the present market. This will help you compare the app idea/outline/expected functionalities with the already existing similar custom CRM apps, chalk out what areas you need to focus more, on or what is redundant, and deploy a competitive custom CRM.

Such a custom CRM can help you transform the customer experience, engagement, satisfaction, and other important KPIs while giving a competitive edge to your business.

3. Understanding React Native Functionalities for Development

As discussed earlier, React Native comes with a lot of pre-built functions that make it stand out from other development frameworks. But to unleash their potential fully, you must know how they work, how to apply them in the right scenarios, and execute or test them.

If you are developing a mobile app, then you will also get to utilize its capacity to create diverse user interfaces (UIs) with them. And to nail all of the functionalities, applicability, and use cases of React Native better and create a custom CRM with it, you will need to have a clear understanding of it.

Apart from React Native’s core components, you can utilize React Native’s custom components for a custom CRM development.

You can easily create and export custom components through React as shown below -

import React from "react";

import { View, Text } from "react-native";

You can easily export class as shown here-

export default class CustomText extends React.Component {

render() {

return (


<Text style={{color: 'blue',fontWeight: 'bold'}}>Click Me</Text>





You can also use the following code for passing props:

import React from "react";

import { View, Text, TouchableOpacity } from "react-native";

import PropTypes from 'prop-types';

export default class CustomText extends React.Component {

constructor(props) {



render() {

return (

<TouchableOpacity onPress={this.props.onPress}>


<Text style={{color: 'red',fontWeight: 'bold'}}> {this.Props.title}







CustomText.propTypes = { title: PropTypes.string.isRequired, onPress: PropTypes.func.isRequired };

However, these are just a few of the instances to know while building a CRM with React Native. To build a custom CRM with React Native like a pro, you need to have an in-depth idea of how React Native works.

Outsourcing Or Developing From Scratch?

As evident from the above discussion, building a CRM with React Native is not a cakewalk unless you are an expert in this field. Furthermore, you will need to maintain and upgrade the system/app in the long run.

To accommodate all the criteria and develop a functional custom CRM, you must have professional real-time experience in creating similar apps. Or else, it is best to outsource it from a professional team. This will ensure that your custom CRM system is developed and launched on time, has high quality, and is suitable for the present market without making a hole in your pocket.
