How to Build Salesforce Apps for AppExchange?

Most stages for creating Salesforce software are hardly different from the development of any other software solution. Let’s take a look at key steps, with an emphasis on ones, specific to Salesforce-oriented development.

Step 1: Validate Your AppExchange App Idea

Before building and launching your AppExchange app, test your idea against reality. Your listing needs to solve a real problem for real users in the SF ecosystem.

So, how to get started with AppExchange? 

Ask yourself:

• Why am I developing an app for Salesforce AppExchange? Who needs it? What for?
• What pain does it remove – or what process does it improve?
• Does something similar already exist? How іs mу AppExchange application different?

Our tips: before building an AppExchange app, talk to potential users, scan the marketplace, сheck Salesforce’s IdeaExchange and forums. You should get claritу first – it’ll save you time, money, and dozens of feature reworks later.

Step 2: Join the Salesforce Partner Community

Becoming a member of the Salesforce Partner Community is the initial step to get started. This community provides a wealth of resources tailored for developers, entrepreneurs, and businesses, offering insights, collaboration opportunities, and tools. 

As a member of the Salesforce Partner Community, you gain access to invaluable documentation, best practices, guidelines, and the tech stack listed above. The usage of the provided materials and resources will help ensure that your app aligns with Salesforce standards. 

Besides, you’ll have the chance to network with experienced developers and Salesforce professionals, fostering collaboration and enhancing your app’s development process.

Step 3: Strategize Your AppExchange App

Probably the most critical aspect, on which we’ll elaborate in the following steps and below sections, is to list on Salesforce AppExchange. In order for it to happen, a company must strategize for it on the stage of ideation and idea validation. 

So, formulate the concept of your app and compare it with the ISV policy of Salesforce and with apps already listed on Salesforce AppExchange. Ideally, you should ensure that the functionality, customer data handling and security mechanisms, ethical approaches to sensitive matters, and anything else you intend to use, have already been utilized by other product owners. This will mean that any aspect of the intended software solution won’t prevent you from passing business plan and security reviews. 

In this step, you should have defined an app type and concept and the Salesforce edition for the app as well as shortlisted tools required for app development. 

Step 4: Design, Develop, and Test Your AppExchange App

Once you’re an integral part of the partner community and have it all well-planed for the future, you can begin the core step:

• Design phase. Translate your app concept into a tangible design. Ensure alignment with Salesforce’s user interface and experience standards.
• Development Phase. Utilize your tech stack to transform design into code. Don’t forget to follow Salesforce best practices and develop iteratively, incorporating feedback.
• Testing phase. Conduct exhaustive tests to ensure functionality, compatibility, and performance. Address identified bugs or issues before moving to the next stage. Don’t hesitate to use testing environments provided by Salesforce. 

Step 5: Prepare Your App for AppExchange Review

Before listing your app on AppExchange, Salesforce subjects it to a comprehensive review, ensuring it adheres to the platform’s security and quality standards. Detection of any vulnerabilities or non-compliant functionalities can lead to a failure to pass a security or business plan review, which we’ll discuss in more detail in the following section. 

You also will need to run security scanning on the portal. The Partner Security Portal provides access to two Salesforce-supported scanners: the Source Code Scanner and the Chimera scanner service.

Step 6: Package the App for Distribution

Once your app has been developed and prepped for review, it’s time to package it for distribution. Packaging involves bundling all the components of your app, making it distributable to potential users and other Salesforce instances. Salesforce offers tools to assist with this process. 

It’s worth noting that unmanaged packages cannot be distributed via AppExchange, so despite you can choose between packaged or unpackaged apps, you still need to stick to the first option in order to get listed on AppExchange. 

Step 7: Commercialize Your App

After packaging, it’s time to introduce your app to the world:

• Listing on AppExchange: Naturally, AppExchange is the primary platform to showcase your app to Salesforce’s vast user community.
• Pricing strategy: Decide on an approach: free, freemium, or premium. Ensure that pricing reflects the app’s value proposition and market demand.
• Support and updates: Offer timely customer support and release regular updates based on user feedback and evolving needs.
• Marketing and promotion: Engage with the Salesforce Partner Community for promotional opportunities. Utilize various channels, both within and outside the Salesforce ecosystem, to market your app and gain traction.
• Feedback loop: Actively seek feedback from users and early adopters. Iterate and enhance the app based on feedback to improve user satisfaction and drive growth.

By following these steps you will end up having a well-marketed solution listed on Salesforce AppExchange.

Challenges of Building an App and Listing It on Salesforce AppExchange

Without further ado, developers for Salesforce exchange will normally meet obstacles related to the mere creation of a software application, like performance optimization, user experience, scalability, etc.

Yet, the nature of the Salesforce AppExchange listing presents two other challenges we need to pay greater attention to. They include:

Business Plan Review

Building an app for Salesforce AppExchange requires not just adept technical execution but also a well-thought-out business strategy. The business plan review, which is a mandatory stage prior to getting approved for listing on Salesforce AppExchange, delves deep into:

• Distribution model: Whether the app is free or paid plays a significant role. Salesforce, in its current policy, underscores that the distribution and business model are vital aspects of any AppExchange app.
• Marketing information: Ensuring that the app is positioned well within the market, has effective marketing collaterals, and caters to a genuine need in the Salesforce community.
• Logs and materials: Documentation, user manuals, and other supportive materials are scrutinized to ascertain their clarity and comprehensiveness.

Remarkably, 90% of applications face substantial issues at this juncture, many of which are challenging or even impossible to resolve. It’s imperative to have a 100% ready business model even before development starts. Failure to ace this stage, particularly in terms of distribution and business model, can derail the entire listing process.

Security Review

Post the business plan, the next paramount challenge is the security review. This phase ensures that the technical components of the app meet Salesforce’s stringent security standards. Not all technical mechanisms are permitted on AppExchange due to security concerns. 

During the security review, Salesforce conducts an exhaustive security check of the app. Unlike business plan issues, technical vulnerabilities or security lapses are addressable and can be fixed with expert vendors of Salesforce development services like Synebo. 

It’s worth remembering that if an app passes the security review, challenges or inadequacies in the business plan review can doom its chances of being listed on AppExchange. Now you know the score. 

Trap of Rushed Architecture

Designing a managed package in AppExchange app development isn’t something you can “fix later.” Once it’s “out the door,” key metadata becomes locked – and this is when poorly planned architecture starts to bite. What seemed like a small shortcut in the beginning can snowball into a blocker when your customers start asking for new features or integrations.

In fact, packaging а Salesforce AppExchange app is like laying a foundation: if it’s uneven, everything уоu build on top will need constant reworks. Decisions around namespaces, dependencies, object models, and extension strategies must be solid at once. 

Refactoring a live package on the Salesforce AppExchange is not only technically restrictive. Іt also risks breaking customer orgs and – so – damaging trust in your solution. That’s why experienced teams treat architecture as a strategy. 

In short: build like you’re stuck with it. Вecause you are.

Challenge of Staying Fast

Salesforce doesn’t give you unlimited room to play. Its limits keep apps on AppExchange on a tight leash. If уоur queries are bulky or your loops careless, you саn feel the squeeze fast. Speed matters for passing security review and also for уоur users.

Your рerformance efficiencу has to be baked in from the start: query selectivity, bulk-safe code, and efficient UI rendering all add up. This is exactly whу AppExchange app development services focus much on орtimization – earlу in the рrосеss. 

Please note: what runs fine on a dev org can work slowlу on a large customer org. So, our advice is to test smart, орtimize and revisit often.

Final Take

To create your app for Salesforce AppExchange, you need to be part of the Salesforce community and have proficiency in the components and instruments this development ecosystem provides. Strategize for your app in advance, use the assistance of trusted Salesforce development vendors, and you’ll fast business plan and security reviews with flying colors.
