Salesforce powers over 150,000 businesses worldwide, helping them manage customer relationships, automate workflows, and build custom applications. A big reason for this is its ability to integrate, scale, and adapt.
But its adaptability is paired with a level of complexity—hence the need to develop.
Successful Salesforce development requires following structured best practices to keep projects scalable, secure, and easy to maintain.
This guide covers key best practices in Salesforce development. Following these practices improves Salesforce code quality and helps developers create high-performing solutions that grow and adapt with your business needs.
What is Salesforce development?
Salesforce development is the process of customizing, extending, and optimizing the Salesforce platform to fit specific business needs. Organizations use Salesforce to manage customer relationships, automate workflows, analyze data, and integrate with external systems. While Salesforce provides many out-of-the-box features, businesses often require custom development to build solutions that align with their operations.
Salesforce development can be categorized into two main approaches:
Declarative development (low-code/no-code): Uses point-and-click tools like to automate processes, create custom objects, and configure business logic. This approach does not require coding and is often managed by Salesforce administrators.
Programmatic development (custom coding) – Uses structured languages to build complex automation, integrations, and custom user interfaces. This approach is necessary when declarative tools cannot handle advanced business requirements.
Languages used by Salesforce developers
There are several technologies and languages Salesforce developers use when creating and deploying their products. They include:
Apex: A strongly typed, object-oriented programming language used for backend logic and automation.
Visualforce: A framework for building custom UI components in Salesforce Classic.
Lightning Web Components (LWC): A modern JavaScript-based framework for creating dynamic, reusable user interfaces.
SOQL & SOSL: Query languages used to retrieve and search for records efficiently in the Salesforce database.
Salesforce APIs: REST, SOAP, and Bulk APIs allow developers to connect Salesforce with external applications and services.
Common use cases for Salesforce development
Salesforce is used by many, and across a variety of use cases. Common ones include:
Automating business processes: Creating triggers, workflows, and scheduled jobs to streamline operations.
Building custom applications: Developing industry-specific applications inside Salesforce.
Enhancing user experience: Designing interactive dashboards, reports, and UI components with Lightning Web Components.
Integrating with external systems: Connecting Salesforce with third-party software (ERP, marketing platforms, payment systems, etc.).
Improving data management: Implementing data validation, deduplication, and automated record updates to maintain data quality.
Salesforce development empowers businesses to customize their CRM, optimize performance, and scale operations efficiently. When implemented correctly, it enables companies to stay competitive by leveraging automation, data insights, and seamless integrations.
Why you should follow these Salesforce development best practices
Salesforce is a powerful platform, but without structured development practices, projects quickly become unmanageable, inefficient, and difficult to scale. Ignoring best practices results in performance bottlenecks, security vulnerabilities, and high maintenance costs—all of which slow down business operations and limit Salesforce’s full potential.
Following best practices is more than writing cleaner code—it’s about creating scalable, secure, and maintainable solutions that adapt as business needs evolve. And the time to implement these best practices is from the very beginning.
A well-architected Salesforce implementation allows teams to deliver high-quality features faster, reduce technical debt, and streamline collaboration between developers, admins, and business stakeholders.
Skipping best practices leads to technical debt—meaning costly rework, slow performance, and frustrated end users. A well-structured Salesforce solution adapts to business growth, reduces operational risks, and delivers long-term value.
If your still not convinced, consider these key reasons best practices matter:
Improves Salesforce code quality: A structured approach reduces bugs, inefficient queries, and unnecessary complexity.
Prevents governor limit violations: Salesforce imposes strict limits on queries, CPU time, and API requests. Optimized code avoids hitting these limits.
Simplifies future enhancements: Modular, reusable code means less effort is needed to introduce new features.
Strengthens security and compliance: Implementing role-based access, encryption, and secure APIs protects sensitive business data.
Enhances team collaboration: Standardized development practices allow multiple developers to work together efficiently without conflicts.
Reduces post-launch issues: Thorough testing and deployment strategies help catch errors before they impact users.
Maximizes Salesforce performance: Efficient SOQL queries, bulk processing, and asynchronous execution keep the system running smoothly.
40 Salesforce development best practices to follow for a successful build
Now that we’ve convinced you of the importance of implementing best practices in Salesforce development, here are the ones we recommend. We have broken them into categories to help clarify why they are needed and to create a simplified developer best practices checklist.
Building scalable and future-proof Salesforce solutions
A well-architected Salesforce solution adapts to business growth without performance bottlenecks or costly rewrites. Scalability is not just about handling more users or data—it’s about structuring development in a way that makes enhancements easier, prevents governor limit violations, and supports long-term business agility.
When Salesforce solutions lack scalability, teams experience slow performance, unmanageable codebases, and expensive redevelopment efforts when new business needs arise.
Following best practices for scalability ensures that Salesforce development remains flexible, high-performing, and maintainable over time.
Best practices for scalability:
Design for long-term scalability by separating UI, business logic, and data layers. This modular approach improves maintainability and simplifies enhancements.
Use bulkified Apex code and collections to efficiently process large data sets while preventing governor limit violations.
Implement modular architectures by structuring code into reusable classes, making it easier to extend features without modifying core functionality.
Leverage asynchronous processing (Batch Apex, Queueable Apex, Future Methods) to handle large operations without affecting user experience.
Optimize Salesforce Object Search Language (SOQL) queries by using indexed fields, limiting query results, and reducing unnecessary database calls.
Limit synchronous processing to avoid performance slowdowns for users interacting with the system in real time.
Regularly analyze and refactor code to remove redundancies and improve efficiency as business needs evolve.
Writing clean, modular, and reusable Apex code
Best practices in Apex development plays a critical role in Salesforce customization, but without proper structure, code quickly becomes unmanageable, inefficient, and difficult to scale. Poorly written Apex leads to hard-to-maintain logic, repetitive code, and performance bottlenecks.
Following Salesforce Apex best practices for Salesforce development creates well-structured, reusable, and testable code, allowing teams to iterate faster, debug efficiently, and extend functionality without breaking existing features. A clean and modular approach also supports collaboration and helps improve salesforce code quality.
Best practices to bulkify Apex development:
Structure Apex code with a single trigger per SObject and use a trigger framework to centralize logic. This prevents conflicts and improves maintainability.
Leverage Apex design patterns such as the Singleton, Factory, and Service Layer patterns to separate concerns and improve code organization.
Write reusable service classes to handle business logic independently of triggers and controllers, making the system more flexible.
Encapsulate SOQL queries and DML operations within dedicated classes to improve reusability and prevent governor limit violations.
Use interfaces and abstract classes to enable code reusability across multiple implementations.
Break down large methods into smaller, single-responsibility functions to improve readability and maintainability.
Write testable components that use dependency injection, allowing seamless unit testing without requiring database interactions.
Driving business success with quality-driven development
A well-built Salesforce solution delivers value beyond functionality—it must be reliable, resilient, and aligned with business goals. Poorly tested and rushed development leads to unexpected failures, security vulnerabilities, and costly post-launch fixes.
Apex best practices for Salesforce development should incorporate testing strategies and automation to minimize defects and streamline releases. Teams that adopt structured testing and deployment workflows reduce production risks, lower maintenance costs, and improve user adoption.
Best practices for quality-driven development:
Conduct thorough unit testing to cover all possible scenarios, including bulk data processing, error handling, and edge cases.
Use mocking frameworks and test data factories to create test records dynamically, improving test reliability.
Write test classes that exceed the 75% code coverage requirement, focusing on functional correctness rather than just hitting the minimum threshold.
Ensure business requirements drive test cases, verifying that each feature functions as expected before deployment.
Automate deployment processes using Salesforce DX and CI/CD pipelines to reduce manual errors and accelerate releases.
Implement static code analysis tools to detect inefficiencies, security vulnerabilities, and code inconsistencies before deployment.
Test in a sandbox or scratch org first to validate changes before they reach production.
Adopt a test-driven development (TDD) approach where unit tests are written before implementing new features.
Standardizing development practices for team collaboration
Your Salesforce development requires a structured approach that promotes clarity, consistency, and collaboration. Without standardized development practices, teams struggle with conflicting code versions, inconsistent implementations, and difficult knowledge transfer, leading to inefficiencies and delays.
A well-documented, source-driven approach allows multiple developers to work seamlessly on the same Salesforce solution, reducing errors and making it easier to onboard new team members.
Best practices for team collaboration in Salesforce development:
Maintain clear naming conventions for Apex classes, methods, and variables to improve readability and consistency across the codebase.
Use descriptive names for objects and fields to make data relationships clear and avoid confusion in queries and reports.
Document business logic and workflows to facilitate knowledge transfer between developers, admins, and business stakeholders.
Follow source-driven development (SDD) principles to manage metadata and code as part of a structured version control process.
Implement Git version control for team collaboration, allowing developers to track changes, merge updates efficiently, and prevent code conflicts.
Use branching strategies (feature branches, development branches, and release branches) to maintain code stability while enabling continuous development.
Leverage pull requests and peer code reviews to catch errors early, enforce best practices, and improve overall code quality.
Adopt a consistent deployment workflow using CI/CD pipelines to standardize how changes move from development to production environments.
Embedding security and compliance in every development stage
Last but by no means the least—security.
Security is a critical aspect of Salesforce development, protecting business data, customer information, and system integrity. Misconfigured security settings expose sensitive records to unauthorized users, while hardcoded permissions make it difficult to adapt as access requirements change.
A security-first approach is paramount. Salesforce solutions must meet compliance requirements, prevent data breaches, and maintain user trust.
Best practices for Salesforce security and compliance:
Apply CRUD, FLS, and Sharing Rules to safeguard data integrity by ensuring users only access the records and fields they are authorized to view or edit.
Avoid hardcoded user permissions—use custom settings and permission sets to manage access dynamically.
Encrypt sensitive data using Salesforce Shield Platform Encryption where applicable to enhance data security.
Monitor Apex governor limits to prevent performance issues that could expose data inconsistencies.
Use Named Credentials for API authentication to store external system login details securely instead of hardcoding credentials in Apex.
Audit login activity and permission changes to detect and respond to unauthorized access attempts.
Secure Visualforce and Lightning Components by sanitizing user inputs and using with sharing in Apex controllers to enforce security rules.
Implement two-factor authentication (2FA) and single sign-on (SSO) to strengthen authentication processes.
Regularly review security health check reports in Salesforce to identify and fix potential vulnerabilities.
Follow compliance regulations (GDPR, HIPAA, CCPA) by implementing data retention policies and anonymizing personal information when required.
