About the technology
What X++ does
X++ is the main language for custom work in Microsoft Dynamics 365 Finance and Operations and older Dynamics AX systems. Teams use it to shape business logic, forms, workflows, batch jobs, and data handling inside the ERP. It is built for complex finance, supply chain, and operations processes.
Common work
- Extend standard ERP behavior without breaking core processes
- Build business rules, validations, and posted document logic
- Adjust forms, queries, and reports for daily operations
- Connect Dynamics AX or Dynamics 365 to other systems
Tools and stack
Strong X++ work usually sits inside the Microsoft ecosystem. Experts work with Visual Studio, the Dynamics 365 development environment, extensions, models, and version control. They also need solid knowledge of SQL Server concepts, security roles, batch processing, and integration patterns.
When to bring in help
Companies bring in freelance X++ specialists when an upgrade is sensitive, a legacy customization is hard to untangle, or a rollout needs extra delivery capacity. This is common in Germany when internal teams need short-term support for finance, logistics, or manufacturing changes. Remote collaboration works well, but on-site time can help during workshops and go-live support.
What good specialists deliver
A strong X++ professional writes clean extensions, avoids unnecessary overlayering, and understands how Microsoft updates affect custom code. They test business scenarios, handle data migrations carefully, and document changes clearly. They also know when a process should be redesigned instead of patched.
What to look for
Look for specialists who have worked on real Dynamics AX or Dynamics 365 Finance and Operations projects, not only sample code. They should understand the business process behind the request, communicate clearly with functional teams, and explain risks before they touch production. For Germany-based work, strong English is often enough for remote delivery, while German helps in local workshops and user-facing sessions.
Frequently asked questions
What clients ask us most about X++ — answered in short.
X++ is used to customize Microsoft Dynamics 365 Finance and Operations and older Dynamics AX systems. It supports business logic, forms, batch jobs, validations, workflows, and data access inside the ERP. Companies use it when standard configuration is not enough for their finance or supply chain process.
No. X++ is still central in Dynamics 365 Finance and Operations, and many specialists also support older AX and Axapta estates. That makes it important for both active cloud projects and long-running legacy landscapes that still need change.
X++ is the native language for application logic in Dynamics ERP, while C# is usually used around it for integration or tooling. For custom business behavior inside the ERP, X++ is the better fit because it works directly with the application model. A good specialist knows where each language belongs.
A strong X++ specialist should also understand data entities, security roles, integration patterns, SQL Server basics, and the Dynamics extension model. Knowledge of finance, warehouse, or manufacturing processes is often just as important as coding skill. That mix helps them build changes that fit the business.
X++ projects often need someone who has already shipped real ERP changes, especially if the system is heavily customized. Smaller tasks may need only a focused specialist, but upgrades, integrations, and production issues usually need broader platform knowledge. The safest choice is someone who can trace effects across the whole process.
Yes, X++ work is often done remotely, especially for code changes, reviews, and testing. In Germany, on-site time is mainly useful for workshops, key user sessions, or go-live support when close coordination matters. Many teams use a hybrid setup.
A strong X++ freelancer can explain why a change belongs in an extension, how it affects existing logic, and how they would test it. Look for experience with Dynamics AX or Dynamics 365 Finance and Operations, clear communication, and clean delivery notes. Good specialists also flag risks before they become production issues.
Companies hire X++ specialists for upgrades, customizations, integration work, data fixes, and support for complex business processes. They are also brought in when an internal team lacks time or needs help with legacy code. In practice, it is often about keeping the ERP stable while making it fit new business needs.
The average hourly rate of freelancers in Germany who have used X++ in their recent projects is 98 €, which corresponds to a daily rate of about 787 € based on an 8-hour working day.
