The process of custom software development typically involves the following stages:

Requirements gathering: This involves understanding the needs and goals of the client and defining the scope of the project.

Design: In this stage, the architecture, user interface, and database schema are designed.

Development: This is where the actual coding and programming of the software takes place.

Testing: The software is tested for bugs, errors, and performance issues.

Deployment: The software is installed and configured on the client's servers.

Maintenance and support: This involves providing ongoing support and updates to the software.
