Custom CRM development steps
A typical custom CRM development project involves multiple phases, covering a process that begins well before the actual coding and continues beyond the launch of your solution.
1
Business analysis
Carry out discovery workshops and software ecosystem evaluations to determine your marketing, sales, and customer support goals and needs and define the right CRM strategy. Then, outline the functional and non-functional requirements of your future solution.
2
Design
Define your CRM’s usage scenario and user journeys and prepare a software specification detailing its architecture and features, along with wireframes and mockups. Then, select an effective tech stack and deliver a PoC to ensure the project’s feasibility.
3
Planning
Define the project’s scope, budget, team composition, and development methodology and establish a project roadmap outlining the development stages, iterations, and deliverables. Then, create a risk management strategy to help overcome potential technical and operational roadblocks.
4
Development
Proceed with front-end and back-end development in multiple iterations and set up necessary CRM integrations via APIs or middleware. Also, execute functional, performance, compatibility, usability, and security tests via manual reviews or with test automation software to identify and correct bugs, UX/UI design flaws, or other issues.
5
Rollout
Conduct user acceptance testing to validate that the application meets the requirements of its intended users. Then, deploy the solution to the selected hosting environment (on-premises, cloud, or hybrid), automating the process with the help of CI/CD tools. Finally, migrate data from your legacy systems to the new CRM after proper data cleansing and validation.
6
Maintenance & support
Provide employees with user training and support to facilitate CRM adoption. Down the line, perform ongoing maintenance to fix technical issues, optimize software operation over time, and modernize it with new features or other enhancements.
Custom vs platform-based CRM
Before embarking on a rewarding but demanding CRM development project, you should decide whether to create your software from the ground up or build it on top of a CRM platform.

Key challenges of custom CRM and how to overcome them
Full ownership of your customer relationship management software and superior control over software implementation are top priorities for many enterprises, but they typically translate into greater effort and accountability. Here are some guidelines to address common custom CRM implementation challenges.
In the short term, building custom CRM systems is typically more expensive than adopting out-of-the-box or platform-based solutions, and costs can snowball during the project due to technical complexities. Also, companies risk overlooking licensing fees for third-party development tools, hosting environment, and hardware or wasting time and resources to develop unnecessary functionality.
- Turn to expert CRM consultants providing project budgeting and license optimization advisory to define a suitable feature set and select cost-effective technologies like open-source tools and deployment models.
- Use feature prioritization techniques, such as the Karno model and RICE framework, to identify essential functionality for your solution.
- Select a CRM development service provider offering a suitable pricing system (fixed price, time and material, etc.) for your project.
- Adopt the Agile approach to project planning, management, and tracking to reduce the initial delivery timeline and support iterative product improvement.
- Apply DevOps methodologies (CI/CD and test automation, microservices, incremental build model, etc.) to streamline the development process and reduce product delivery costs.
Compliance & data security
CRM solutions process sensitive data, such as personal data and business-related information about customers, leads, and offers made, which should be protected from leaks or cyberattacks and managed according to relevant standards and regulations. While CRM vendors typically take care of these aspects, adopting a custom solution implies that safeguarding data and the application itself is your responsibility.
- Equip your CRM with solid cybersecurity features, such as identity and access management, multi-factor authentication, user activity monitoring, dynamic data masking, and encrypted data exchange.
- Perform regular risk assessments via penetration testing to identify and address potential vulnerabilities.
- Implement CRM solutions compliant with the data management standards and legislation applicable to your industry.
- Implement data governance policies defining how data assets should be managed and shared across your company.
Maintenance efforts
Despite accurate testing, software solutions can be affected over time by glitches and degraded performance due to latent defects, changes in the software environment, and other reasons. If your organization opts for a custom CRM application, maintenance, updates, and troubleshooting that would typically be included in a CRM platform subscription will instead become your responsibility.
Consider teaming up with an experienced software maintenance service provider offering post-implementation, long-term assistance who will cover:
- Adaptive maintenance
to adjust the application to your evolving software ecosystem and usage scenario
- Perfective maintenance
to improve the CRM functionality and performance through code optimization or new features
- Corrective maintenance
to fix glitches or bugs compromising the software operation and user experience
- Preventive maintenance
to ward off future problems and improve maintainability via code refactoring or backup
