Hello @SuhebM ,

You must plan your core requirements and design a proper framework using guidelines from ServiceNow Documentation.

Any custom applications follow the request and fulfill framework, meaning someone requests something from a formulary or any other channel such as VA, email and so on, and then someone fulfills it from a workspace or a list view.

An example might be a custom application for your HR module in which employees can register volunteering activities, or, also, a custom application for your ITSM that register donation requests of IT Assets.

If my response helped mark as helpful and accept the solution.

hi @SuhebM ,

Before building a custom ServiceNow application, I would mainly consider these points:

1. First check whether the requirement can be fulfilled using OOTB ServiceNow functionality.
2. Decide the application scope and data model — tables, relationships, and whether existing tables can be extended.
3. Define roles, ACLs, and data access requirements from the beginning.
4. Choose the right user experience — Workspace, Employee Center, Service Portal, or UI Builder.
5. Prefer Flow Designer and OOTB configuration before custom scripting.
6. Consider integrations, notifications, reporting, and future scalability.
7. Finally, think about upgradeability and avoid unnecessary customizations of OOTB components.

If this helps, please mark it as Helpful and accept the solution.
