How to Customise Microsoft Dynamics 365 Without Breaking the System
By Robert Ulrich
Customising Dynamics 365 can transform how your business operates without adding complexity. Smart customisation improves usability, aligns workflows, and boosts overall productivity. But reckless changes risk breaking user interfaces and slowing adoption.
Understanding the difference between customisation and configuration is key to success. While configuration adjusts out-of-the-box settings, customisation extends tables, workflows, and Power Apps. This ensures flexibility and keeps business processes efficient.
Investing in careful customisations helps your Microsoft 365 ecosystem scale smoothly. Integrating Power Platform, Teams, and other tools avoids unnecessary developer intervention. Every thoughtful change supports long-term upgrades and strategic business goals.
What Is Dynamics 365 Customisation And How It Differs from Configuration
Dynamics 365 customisation involves adjusting tables, workflows, and user interfaces beyond standard configuration. You can add new entities, extend Power Apps, or include code extensions. These changes let your business processes work the way your team needs.
While configuration tweaks out-of-the-box features, customisation allows deeper control over usability and productivity. For example, changing a form or building a role-specific dashboard is customisation. This ensures your system matches real-world processes.
Smart customisations support adoption and future upgrades without breaking Microsoft 365 tools. Using Power Platform and Teams strategically maintains flexibility. It also reduces unnecessary developer intervention and keeps changes manageable.
Most Popular Dynamics 365 Customisations
Custom Dynamics 365 adjustments help businesses work smarter and faster. They improve usability, productivity, and align the system with real business processes.
Custom Tables and Fields
Custom tables and fields let your CRM match actual business operations. They make data easier to manage and support key business processes. Properly planned customisations improve productivity without slowing adoption.
Forms and Views
Adjusting forms and views ensures users see the right data at the right time. This boosts usability and reduces errors in workflows. Role-specific dashboards further tailor insights to each user’s tasks.
Business Rules and Workflows
Automating tasks with business rules and workflows removes repetitive manual work. You can use Power Automate or custom code sparingly. This keeps processes efficient and helps employees focus on high-value tasks.
Power Apps Customisation
Extending features with Power Apps customisation enables mobile access to your CRM. Teams can work anywhere without losing connection to business data. It also supports integration with Teams, Outlook, or ERP systems.
Role-Based Dashboards
Dashboards tailored by role give meaningful insights to the right people. They simplify decision-making and increase adoption. Combined with custom tables and forms, they make Dynamics 365 intuitive.
Custom Plugins
When low-code solutions aren’t enough, custom plugins add advanced logic. They extend Dynamics 365 without breaking standard user interfaces. Smart customisations balance power and system stability.
When Should You Customise Dynamics 365?
- Assess if changes impact revenue or compliance before customising Dynamics 365.
- Determine if critical business processes justify deep customisations.
- Avoid unnecessary adjustments that create technical debt.
- Check if out-of-the-box features already meet your needs.
- Leverage standard workflows and tables to reduce developer intervention.
- Plan for smooth Dynamics 365 updates.
- Identify who will manage customisations, plugins, and Power Apps.
- Ensure system monitoring, upgrades, and security keep your CRM stable.
Dynamics 365 Customisation Best Practises for a Stable System
Always use Power Platform first and add custom code only when necessary. This keeps Dynamics 365 scalable, reduces errors, and strengthens your customer relationship management. It also improves overall performance.
Keep customisations modular and fully documented. Organised system entities and custom attributes make maintenance easier. Testing in sandboxes protects workflows and business processes.
Follow Microsoft security and ALM standards. Proper system monitoring ensures smooth upgrades and stable CRM. Applying managed solutions correctly prevents unexpected issues.
Common Customisation Mistakes and Fixes
Hard-coding logic instead of using Power Automate creates brittle customisations. It increases errors and slows productivity.
Replacing standard UI features unnecessarily can break user interfaces and confuse employees. Stick to supported customisations for stability.
Ignoring dependencies or version issues risks failed upgrades. Lack of governance over customisations leads to inconsistent CRM behaviour. Always plan and test changes carefully.
