Salesforce App Development: A Complete Guide to Building Scalable and Custom Applications

Salesforce app development is the solution that provides the flexibility to automate complex workflows, streamline data management, and unify multiple systems into one seamless ecosystem. It ensures that as your business scales, Salesforce adapts with you rather than holding you back.

Standard features and AppExchange apps work initially, but growing businesses often face data inconsistencies and integration challenges. That’s where custom development helps.

In this guide, we’ll cover what Salesforce app development is, why businesses invest in it, and how to build scalable and custom applications that drive efficiency and growth. 

If you’re looking for a way to make Salesforce work for your business, rather than around it, this guide will show you how.

What is Salesforce App Development?

Salesforce App Development is all about creating custom applications on the Salesforce platform to make business operations smoother, automate tasks, and improve customer interactions. These apps can be used internally within a company or shared with others 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: For more advanced features, developers use Apex (Salesforce’s coding language), Lightning Web Components, and Visualforce to build apps with complex functionality.

These apps can integrate with Salesforce’s core CRM as well as other external systems, ensuring all your data stays connected. Plus, since Salesforce is cloud-based, your apps are scalable, secure, and accessible from anywhere.

For a business building custom Salesforce solutions might take time as compared to the ready-to-use solutions which you can install, configure and use instantly. With expansive diversity in operations businesses at the end need tools and systems that work for them, not against them and custom development in Salesforce empowers you with the same thing. 

Approaches for Building Apps on Salesforce

When building an app on Salesforce, organizations typically consider four primary approaches: declarative (no-code/low-code), programmatic (code-based), hybrid (a mix of both), and AppExchange-based (pre-built solutions). Each approach is unique and offers several advantages, and the choice depends on business needs, complexity, and available resources.

1. AppExchange-Based Approach

Salesforce AppExchange offers pre-built applications developed by third-party vendors, designed to address specific business needs, reducing the need for custom solutions. This approach enables rapid deployment with minimal effort and lower development costs.

While these option provides quick solutions. it’s important to consider potential customization limitations, licensing fees, and vendor dependencies before choosing this method. It is ideal for businesses looking for quick solutions without reinventing the wheel.

If you’re considering this approach, check out our complete guide on Salesforce AppExchange to explore its benefits, popular apps and more.

2. No-Code/Low-Code Approach

The declarative approach leverages Salesforce’s built-in tools to develop applications without requiring any programming.  Features like Lightning App Builder, Flow Builder, and Object Manager help users create and automate business processes. Approval Processes and Validation Rules enable them to define custom data structures and design user-friendly interfaces using a point-and-click approach.

This method is ideal for quick development, easy maintenance, and business users without coding expertise. However, it is best suited for simpler applications, as highly complex business logic, deep integrations, or customized user experiences often require programmatic enhancements.

3. Code-Based Approach

The programmatic approach in Salesforce means writing custom code to add advanced features. It uses Apex for backend logic, Lightning Web Components (LWC) for modern UIs, Aura for older components, and Visualforce for traditional pages. This approach is best suited for custom app development, used when businesses need fully tailored solutions beyond natively-built Salesforce’s capabilities.

4. Hybrid Approach 

The hybrid approach strategically combines declarative and programmatic development to achieve a balance between speed, flexibility, and functionality. Standard customizations, workflows, and UI elements can be configured using declarative tools, while Apex and LWC handle complex backend logic, external integrations, or specialized UI components. 

This approach is one of the most commonly used approaches for developing custom Salesforce applications as it strikes a balances efficiency, and flexibility, ensuring businesses can easily scale solutions with minimal disruptions. However, it requires careful coordination between administrators and developers to ensure seamless implementation and maintainability.

Plan Your Build with Right Approach

Selecting the right development approach is just the first step in creating a Salesforce application that aligns with your business goals.

Whether you opt for a no-code, code-based, hybrid, or AppExchange-based solution, the next crucial phase is translating that approach into a structured development process. This is where understanding the Salesforce development lifecycle becomes essential, ensuring a smooth transition from planning to deployment.

Building a custom Salesforce app isn’t just about writing code or configuring tools, it requires a well-planned strategy that considers business requirements, user experience, scalability, and integration needs. 

In the next section, we’ll walk through the complete process of building a custom Salesforce app with an example, outlining 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 logo and color to the App

You can Enhance user experience by adding a logo and color scheme that aligns with the organization’s branding. This helps in visually distinguishing the custom app.

Note:

• It’s recommended to follow the naming convention for the app so that it should be easily readable and accessible to desired users. 
• Continuing with our above example, here the App Name will be Event Management, description: App designed for Event Management Team. Similarly the logo is uniquely designed for Event Management. 

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 needs.

1. For Navigation Style: Standard Navigation (for internal users)

Console Navigation (for service agents handling multiple cases)

For our use case, Event Management app is for internal users so we have selected Standard Navigation as Navigation Style, Similarly we want that our users managing the events should be able to access it from desktop as well as to increase the efficiency, so we have selected Desktop and Phone as Supported Form Factors, As we don’t need to personalize the app more by disabling some of the options, so all the checkbox are left unchecked.

2. Utility Bar Configuration: 

The next Page is for Utility Items (available at the bottom left corner):

One should utilize the utility bar to provide users with persistent access to productivity tools like notes, recent items, or a softphone, regardless of which tab they are currently viewing. Consider which tools would be most beneficial for users within the context of your app to improve efficiency.

It offers different alignment options:

• Add the required utility items according to the business requirements:

For our example scenario,event management users need to access Phone, recent items and notes at any time (irrespective of the current tab), so we have added these 3 utility items:

Step 3: Adding Objects and Tabs

1. Select Required Objects and Tabs

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

• Set the objects in an order that will be quick access to the 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, required Tabs will be Home, Campaign, Events, Leads, Contacts, Tasks, Chatter, Reports, Dashboards

2. Assign User Profiles:

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

In our scenario, Custom Sales Profile, Marketing User, System Administrator are only profiles that need access to 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 need: 

• You can add Dashboards on the page for displaying the data dynamically and in a concise form
• Add 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 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: 

Now, if you want that the Dashboard should be viewed by the users according to their security and sharing permissions. For this, edit the dashboard and navigate to gear icon (settings), then there will be an option of View Dashboard As and Select ‘The Dashboard Viewer’.

Step 5: Setting a Default Application for Specific Profiles

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

This helps in navigating the user to the required App only and makes it easy for the profile users to view and access their designated 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 profile level, select any profile, then edit. 
• Now, go to Tab Permissions and change the permissions for the required apps, available options:- Default On, Default Off, Tab Hidden. 

This was just an example of how a custom app in Salesforce is built. No matter in which industry you are operating in having a customized application that works within the Salesforce ecosystem.

Build Your Salesforce App the Right Way

A custom Salesforce app sounds promising: it’s tailored, flexible and built specifically for your business and people. But here’s the reality: a lot of companies rush into app development without considering long-term scalability, ROI and usability which may lead to development of an app that drains resources instead of driving real impact.
