When missing functionality in , the decision to develop the functionality yourself or to look for an existing application on the AppSource marketplace is crucial. This decision can significantly impact your implementation timeline, maintenance workload, and overall business efficiency. Generally, it's advisable to explore existing applications on AppSource before opting for custom development, unless your needs are highly specific and complex. This approach often provides faster implementation, easier updates, and less maintenance burden compared to custom development.
Reasons to Consider an Existing App
Wide Range of Options
The offers a vast selection of apps catering to various industries and business requirements. This increases the likelihood of finding a suitable solution that meets your needs without the need for custom development.
Future needs
It is also important to think about what are your needs going to be in the future. Maybe you just need one feature today, but with your planned growth there are other features and functionalities that you should consider. Are these offered in the app? You may want to think about long-term plans before developing for a specific current need.
Regular Updates
App developers typically update their applications to maintain compatibility with the latest Business Central versions. This ensures that your solution remains up-to-date with new features and security patches, reducing your maintenance workload. Regular updates from app developers mean you don't have to worry about the technical aspects of keeping your solution current.
Tip: you can see when the latest update occurred, this can help give you an indication about how active the developer is in maintaining its solution.

Community Support
If you encounter issues, you can often leverage the app developer's support network and user community. This can be a valuable resource for troubleshooting problems, sharing best practices, and getting the most out of your app. Community support can provide quick solutions and insights that might not be readily available if you were to develop the functionality yourself.
When to Consider Custom Development
Unique Needs
If your required functionality is highly specialized and not addressed by any existing app, custom development may be necessary. Custom development allows you to tailor the solution precisely to your unique business processes and requirements.
Tip: If you are already using a Microsoft Dynamics 365 product, start by seeing if you could leverage the Power Platform to extend the functionality that you need. This low-code option will be easier to maintain since there is the Microsoft community available to support it.
Deep Integration
When you need tight integration with other systems or complex data manipulation, custom development might be the best approach. Custom solutions can be designed to seamlessly integrate with your existing systems, ensuring smooth data flow and operational efficiency. This level of integration is often difficult to achieve with pre-built apps.
Tip: what is available from an integration standpoint?
Control Over Features
If you need to customize every aspect of the functionality, building your own solution provides more flexibility. Custom development gives you complete control over the features and capabilities of your solution, allowing you to create a tailored experience that aligns perfectly with your business goals.
Key Factors to Consider When Choosing Between an App and Custom Development
Complexity of the Required Functionality
Simple needs are more likely to be met by an existing app, while complex requirements may require custom development. Assess the complexity of the functionality you need and determine whether it can be addressed by an existing app or if custom development is warranted. You may be surprised how close you can get with an industry-specific application.
Development Expertise
If your team lacks the necessary development skills, finding an existing app is likely the easier option. Custom development requires a skilled team of developers who are familiar with Business Central and its ecosystem. If you don't have access to such expertise, leveraging an existing app can save you time and effort or look at a Power Platform extension.
Budget
Custom development can be more expensive than purchasing an existing app, depending on the complexity of the required features. Consider your budget constraints and weigh the costs of custom development against the benefits of using a pre-built app. While custom development offers greater flexibility, it often comes with higher costs and longer implementation times.
Different parameters you need to consider:
- Which platforms
- How many people will need to access
- Are there any other integrations you need to consider
- How picky are you for the UI design
- Where are the databases and level of security?
- How many different features do you need?
Conclusion
The decision to develop functionality yourself or to look for an existing app in Microsoft Dynamics 365 Business Central depends on various factors, including the complexity of your needs, your team's expertise, and your budget. Exploring existing applications on the AppSource marketplace is generally a good starting point, as it offers a wide range of options, regular updates, and community support. It will also give you a baseline when evaluating the costs.
By carefully evaluating your requirements and considering the pros and cons of each option, you can make an informed decision that best supports your business objectives.
