Should every feature be bulkified?
No — not every UI action needs to be designed as if it will process many records on day one, but bulkification should still be the default at shared boundaries in Salesforce. The pragmatic rule is simple: keep the UI Controller class thin, make the Service class and Selector class bulk-safe, and treat public entry points as Salesforce best practice guardrails for scalability and reuse.
What this really means for feature development is that you are not choosing between elegance and safety — you are choosing where to place the complexity so you avoid technical debt later. In an MVC-like architecture (Controller → Service → Selector), the controller can handle single-record processing for convenience, while the service layer absorbs batch processing concerns and protects the system from future reuse risks.
A good way to think about it is this: the UI is the front door, but the service layer is the foundation. If the foundation is not bulk-safe, the moment a feature is reused by triggers, batch jobs, imports, or automations, you inherit avoidable refactoring work and weaker performance optimization.
A practical line to draw
- Always bulkify triggers, batch jobs,
@InvocableMethodlogic, integrations, and any reusable services that may be called from more than one place. - Keep the UI Controller class lightweight when a feature is truly limited to one record, but have it call a bulk-safe service rather than embedding business logic.
- Use collection-based signatures in shared services and selectors to improve code reusability and reduce the risk of expensive rewrites.
- Avoid boilerplate code in the controller layer if it does not add value, but do not let that become an excuse for logic that cannot scale.
- If a feature might later be exposed to Flow, automation, or integration, assume bulkification will eventually matter and design for it early.
Why the architect is partly right
A technical architect is usually trying to prevent the hidden cost of “it only needs one record today.” In Salesforce, that mindset is often justified because platform entry points can change quickly, and what begins as a small UI action may later become part of a broader enterprise architecture patterns strategy. Building for scalability up front is usually cheaper than discovering the limit only after production volume exposes the flaw.
Where the balance usually lands
The most maintainable pattern is often:
- Bulkify the core
- Keep the UI wrapper simple
- Let the controller pass a single record into a list-based service method
That approach preserves design pattern application without forcing every method to look enterprise-heavy. It also aligns with development guidelines/standards that favor clean separation of concerns, better trigger optimization, and lower maintenance overhead.
The deeper question worth asking
The real question is not “Can this feature process 10 records today?” It is “Will this logic still be safe, reusable, and easy to evolve when the business asks for more?” That shift in framing turns bulkification from a checkbox into a strategy for reducing code complexity vs. necessity tradeoffs while protecting your architecture from avoidable risk.

- a blog-style thought leadership article,

Should every feature in Salesforce be bulkified?
No, not every UI action needs to be designed for bulk processing initially. However, bulkification should be the default approach at shared boundaries in Salesforce to ensure scalability and reduce technical debt.
What is the recommended approach for designing UI and service classes?
The recommendation is to keep the UI Controller class thin and lightweight for single-record processing while ensuring that the Service and Selector classes are bulk-safe to absorb batch processing concerns. This architectural pattern is particularly important when integrating Salesforce with external automation workflows that may trigger bulk operations.
What types of features should always be bulkified?
Always bulkify triggers, batch jobs, `@InvocableMethod` logic, integrations, and any reusable services that may be called from multiple places to ensure reliability and performance optimization. These components form the foundation of enterprise-grade Salesforce solutions and are frequently invoked by automation tools and third-party applications.
How can developers avoid technical debt in Salesforce?
To avoid technical debt, developers should build with scalability in mind from the outset, avoiding the mindset of "it only needs one record today" and designing features that are safe, reusable, and easy to evolve. Implementing structured training and documentation systems helps ensure development teams maintain consistent coding standards and architectural patterns across the organization.
What is a practical guideline for balancing UI and service complexity?
A practical guideline is to bulkify the core logic, keep the UI wrapper simple, and let the controller pass a single record into a list-based service method. This balance maintains clean separation of concerns while optimizing performance, making it easier to optimize Salesforce licensing costs by ensuring efficient resource utilization.
Why is it important to consider future scalability in feature development?
Considering future scalability is essential because as business needs evolve, what starts as a small UI action may need to be part of a broader enterprise architecture, making upfront bulkification strategies more cost-effective. Organizations that plan for scale from the beginning can more easily leverage advanced Salesforce capabilities like Agentforce without requiring extensive refactoring.
What is the deeper question to ask when designing features in Salesforce?
The deeper question to ask is whether the logic will remain safe, reusable, and easy to evolve as business demands grow, which shifts bulkification from a mere requirement to a strategy for reducing code complexity and ensuring long-term maintainability.
