Not every company should build a custom application right away. Sometimes an existing SaaS product solves the problem faster and cheaper. A custom web app makes sense when the process is specific, data needs to move in a particular way, or existing tools create too much manual work.
If the problem is standard, such as CRM, email, invoices, or basic task management, an existing tool may be enough. It lets the team validate the process before investing in features they do not fully understand yet.
Custom development makes sense when the business advantage lives in the process. Examples include custom order handling, customer portals, quote systems, reporting, or integrations across several data sources. In that case, the app is not a nice extra. It is an operating tool.
A practical approach is to clarify the process, test it with simple tools, and then build a custom app around proven requirements. This reduces guessing and increases the chance that the product will actually be used.

Fast validation
Custom
Unique workflow
A custom application is strongest when it reduces manual steps, improves access to data, and supports a way of working that cannot be recreated well in standard software.
