Salesforce app development enables businesses to automate complex workflows, manage data more effectively, and integrate disparate systems into a seamless, unified operation. As your business grows, Salesforce adapts to your needs without slowing you down.

While standard features and AppExchange apps are helpful at first, growing businesses often encounter problems with data inconsistencies and integration.

That’s where custom development helps.

In this guide, we will explain what Salesforce app development is and why businesses choose to invest in it. We will also show you how to create custom applications that can help your business grow and work more efficiently.

If you want Salesforce to fit your business needs instead of the other way around, this guide will help you do that.

What is Salesforce App Development?

Salesforce App Development involves creating custom apps on the Salesforce platform. These apps help businesses operate more efficiently, automate tasks, and enhance customer interactions. Companies can use these apps internally or share them through Salesforce AppExchange.

Salesforce makes it easy to build apps in two ways:

1. No-Code/Low-Code Tools: You can create apps without writing code using tools like Flow Builder and App Builder.

2. Custom Development: To create apps with complex features, developers use Apex, which is Salesforce's coding language. They also use Lightning Web Components and Visualforce.

These apps work with Salesforce’s leading CRM and other external systems to keep all your data connected. Since Salesforce is cloud-based, your apps are easy to scale, secure, and can be accessed from anywhere.

Key Characteristics of a Salesforce Application

The following are the key characteristics of a Salesforce application:

• Faster Time-to-Market – Custom Salesforce applications help businesses quickly adapt to market changes. They enable companies to launch new initiatives more rapidly than their competitors.

Building custom Salesforce solutions can take more time than using ready-made options that can be easily installed and started using. However, businesses have diverse needs, and they require tools that support them rather than hinder them. Custom development in Salesforce provides this support.

Approaches for Building Apps on Salesforce

When organizations build an app on Salesforce, they usually consider four main approaches: 

1. Declarative (no-code/low-code): This method requires little to no coding.

2. Programmatic (code-based): This approach involves writing code to build the app.

3. Hybrid: This combines both declarative and programmatic methods.

4. AppExchange-based: This includes using pre-built solutions from the AppExchange.

Each approach has its benefits. The choice depends on the organization's business needs, the complexity of the app, and the available resources.

1. AppExchange-Based Approach

Salesforce AppExchange offers ready-made apps created by third-party companies. These apps are designed to meet specific business needs, which helps avoid the need for custom solutions. This method enables quick setup with reduced effort and lower development costs.

While these options offer quick solutions, it's essential to consider potential limitations, such as customization, licensing fees, and vendor dependence, before making a decision. This method is ideal for businesses seeking rapid results without having to start from scratch.

If you're considering this approach, take a look at our comprehensive guide to the Salesforce AppExchange. It covers the benefits, popular apps, and more.

2. No-Code/Low-Code Approach

The declarative approach utilizes Salesforce’s built-in tools to create applications without requiring programming knowledge. Users can easily build and automate business processes using features such as Lightning App Builder, Flow Builder, and Object Manager. They can define custom data structures and design user-friendly interfaces through a straightforward point-and-click method, thanks to Approval Processes and Validation Rules.

This method is ideal for rapid development and straightforward maintenance. It works well for business users who lack coding skills. However, it is best for simpler applications. If you require complex business logic, deep integrations, or customized user experiences, you will likely need to implement programming enhancements to achieve these goals.

3. Code-Based Approach

In Salesforce, a programmatic approach means writing custom code to create advanced features. It uses Apex for backend logic, Lightning Web Components (LWC) for modern user interfaces, Aura for older components, and Visualforce for traditional pages. This approach is ideal for developing custom apps when businesses need tailored solutions that go beyond what Salesforce offers by default.

4. Hybrid Approach 

The hybrid approach mixes two methods of development: declarative and programmatic. This balance enables the achievement of speed, flexibility, and functionality. You can use declarative tools to set up standard customizations, workflows, and user interface elements. For more complex tasks, such as backend logic, external integrations, or special UI components, use Apex and LWC.

This method is one of the most commonly used for creating custom Salesforce applications. It offers a good balance between efficiency and flexibility, allowing businesses to scale their solutions easily and with minimal disruption. However, it requires close cooperation between administrators and developers to ensure smooth implementation and easy maintenance.

Plan Your Build with the Right Approach

Choosing the right approach to develop your Salesforce application is just the first step in meeting your business goals.

After deciding on a no-code, code-based, hybrid, or AppExchange-based solution, the next important step is to turn that choice into a transparent development process. Understanding the Salesforce development lifecycle is crucial for a seamless transition from planning to deployment.

Creating a custom Salesforce app involves more than just coding or setting up tools; it also requires strategic planning and effective implementation. It requires careful planning that looks at business needs, user experience, scalability, and integration.

In the next section, we will outline the entire process of building a custom Salesforce app using an example. We’ll highlight the key steps to ensure a successful and scalable implementation.

Building Custom Salesforce App: A Step-by-Step Development Process

Step 1: Creating the Application

1. Navigate to Setup , then search for App Manager and open it.

2. Create a New Lightning App:

• Click on New Lightning App (top right corner).

• Add App Name and branding by applying the logo and color to the App.

You can enhance the user experience by incorporating a logo and color scheme that aligns with the organization’s branding. It helps visually distinguish the custom app.

Note:

• It is best to follow a naming system for the app so that it is easy to read and accessible to users. 

• The App Name is "Event Management." This app is made for the Event Management Team. The logo is specially designed for this purpose.

Step 2: Configuring Setup and Navigation Options

Next Page is Setup and Navigation Options:- 

These options are to make the app more personalized according to the business's needs.

• For Navigation Style: Standard Navigation (for internal users)

Console Navigation for Service Agents Managing Multiple Cases

We designed the Event Management app for internal users, so we chose Standard Navigation as the Navigation Style. To help users manage events effectively, we allow access from both desktop and mobile devices. Therefore, we selected Desktop and Phone as the Supported Form Factors. Since we don't need to personalize the app by disabling options, we left all the checkboxes unchecked.

• Utility Bar Configuration: 

The next page is for Utility Items, found in the bottom left corner. 

Use the utility bar to provide users with easy access to tools such as notes, recent items, or a softphone, regardless of which tab they are viewing. Consider which tools will most benefit users in your app, enabling them to work more efficiently.

It offers different alignment options:

• Add the necessary utility items based on what the business needs.

Event management users need to access Their Phone easily, recent items, and notes at any time, regardless of which tab they are on. Therefore, we have added these three tools for convenience.

Step 3: Adding Objects and Tabs

1. Select Required Objects and Tabs

Now, select the objects or tabs that are required for the app:

• Arrange the objects in a way that provides quick access to users.

• Keep navigation minimal—don’t overload users with too many tabs.

• The first tab will be the default landing tab. 

For the Event Management App, the following tabs are needed: Home, Campaign, Events, Leads, Contacts, Tasks, Chatter, Reports, and Dashboards.

2. Assign User Profiles:

• At Last, select the profiles that will have access to this app.

Only the Custom Sales Profile, Marketing User, and System Administrator profiles need access to the Event Management App.

Step 4: Customizing the Home Page

Now customize the Home Page for the Event Management Team. 

1) Go to Setup-> Lightning App Builder -> New Lightning Page. 
2) Customize the Page according to your needs: 

• You can add Dashboards to the page to show data clearly and dynamically.

• Add the related list of child objects

• You can also create lightning web components

• Build CRM Analytics collection (Dashboards or reports)

• Create Screen Flows, etc.

 3) Save and activate the page, and then select the Apps on which you want to show this page:

4) At last, this is how the Event management App will be visible to the users.

Note: 

To make sure users can view the Dashboard based on their security and sharing permissions, first edit the dashboard. Then click on the gear icon (settings). Look for the option called "View Dashboard As" and select "The Dashboard Viewer."

Step 5: Setting a Default Application for Specific Profiles

How to set an app as the default App for a particular profile?

It helps users find the right App easily. It also makes it simple for profile users to see and access their assigned Apps.

• Click on Profile and go to Edit 

• Select Custom App Settings and mark the App as Default 

Note: It’s recommended that only specific apps should be visible for the users belonging to a particular profile. It enhances the security and accessibility of apps. In this use case, we will assign Event Management as default for Custom Sales Profile and Marketing User Profile.

Step 6: Managing Tab Visibility

How to make any tab visible or hide by default?

• At the profile level, select any profile and then edit it. 

• Now, go to the Tab Permissions and change the permissions for the required apps. Available options are: Default On, Default Off, and Tab Hidden. 

This example shows how to build a custom app in Salesforce. Regardless of your industry, having a tailored application that integrates seamlessly with the Salesforce platform is crucial.

Build Your Salesforce App the Right Way

A custom Salesforce app can be very beneficial because it is designed specifically for your business and your team. However, many companies rush into creating an app without thinking about long-term growth, return on investment (ROI), and ease of use. It can result in an app that uses up resources without delivering real value.

A clear vision and the right expertise can turn a Salesforce app into a valuable tool. It can help your teams work more efficiently, enhance customer experiences, and boost business growth. At Codleo, we are a trusted Salesforce app development company. We focus on creating scalable solutions that solve real problems.
