When a CMS is enough
If the website mainly requires editing pages, news, images, and simple forms, a ready-made CMS can be a fast and effective solution.
When custom logic appears
Different roles, approval stages, complex data relationships, specialized reports, or external integrations often justify a custom administration environment.
The main criterion
The admin system should simplify the workflow. If the team has to work around CMS limitations every day, the technology is starting to work against the business.
