Analyse the answers and make an informed decision to choose the preferred type of CRM. One of the good practices is to collect user personas for different team members like managers, customer support, or sales and marketing teams. To collect user opinions, you can perform surveys, discussions, user interviews, and process mappings.
- Select the Right Technology Stack
Selecting necessary technologies can hinder the overall performance, scalability, and maintenance needs of your CRM. Your decision can shape the entire development and integration process. Here are the key options that help you decide the right technology to effectively create CRM software:
Frontend Development:

Database Choice:
- PostgreSQL or MySQL for organized relational data management
- MongoDB for versatile data structures and quick prototyping
API Integration:
- REST API for integrating modern web services

4. Implement Third Party Integrations
Modern businesses utilize multiple software tools to ensure seamless connectivity and workflow efficiency. Create CRM software that needs to integrate with existing system or third-party platforms like email software, customer support, and marketing automation tools.

Start from unit testing for each component, then integration testing to check the module compatibility, and load testing to evaluate system performance under pressure. User acceptance testing and performance testing help identify potential challenges with usability and workflow conditions. Consider platforms like Selenium for UI testing, JMeter for load testing, and Postman for API validation.
- Deployment and Post Maintenance
After ensuring the platform functions as intended, launch the software in a real-world environment using deployment platforms. This includes CI/CD pipelines, like GitHub commands, Jenkins, Azure DevOps, and Bitbucket Pipelines that simplify the deployment process. After successfully launching your CRM software, continuous usage monitoring, performance metrics, bug detection, and regular updates are crucial for ensuring post launch effectiveness.
