Configuration or Custom Code? Making the Right Call in Salesforce

One of the most common design questions in Salesforce is whether a requirement should be met with declarative configuration, such as Flow and validation rules, or with custom code such as Apex and Lightning Web Components.

There is no universal answer. The right choice depends on the requirement, the team that will support it and how the solution is expected to change.

When configuration fits

• The logic is straightforward and likely to be adjusted by administrators.
• Standard features meet the requirement with little workaround.
• The organization has strong administrator capability and limited developer capacity.

When code fits

• The logic is complex, performance-sensitive or handles large data volumes.
• Robust error handling and automated testing are essential.
• The user interface needs behavior that standard components cannot provide.

Consistency matters more than preference

Problems often arise not from choosing one approach over the other, but from mixing both on the same process without a clear pattern. Agree standards for each type of requirement and document them, so future changes follow the same logic.

Good Salesforce solutions use configuration and code where each is strongest, guided by maintainability rather than habit.
