About the technology
X++ in Dynamics
X++ is the object-oriented programming language behind Microsoft Dynamics 365 Finance and Operations. It is used to extend finance, supply chain, commerce, manufacturing, and human resources processes inside the ERP environment. Many companies also search for X++ programming or Dynamics AX expertise when maintaining older implementations.
Business Applications
X++ specialists turn complex operational rules into reliable ERP functions. Typical work includes:
- Extending forms, tables, classes, and data entities
- Building workflows for finance and supply chain approvals
- Customizing warehouse, procurement, sales, and production processes
- Creating reports, batch jobs, and periodic business tasks
The work must fit standard application behavior while supporting the company’s specific processes.
Tools and Ecosystem
X++ work is closely tied to Visual Studio, Lifecycle Services, Azure DevOps, and the Dynamics 365 development environment. Strong professionals understand extensions, metadata, data entities, Electronic Reporting, and the application object tree concepts inherited from Dynamics AX. They also work with SQL awareness, REST or OData integrations, Power Platform connections, and deployment pipelines.
When to Hire Expertise
Companies bring in freelance X++ specialists during new Finance and Operations implementations, upgrades from Dynamics AX, and major process changes. External support is useful when an internal team needs focused capacity for a release, integration, performance review, or legacy customization. In Germany, projects may also require close coordination with finance, manufacturing, or logistics teams at local sites.
Signs that specialist support is needed include:
- Customizations block an upgrade or create maintenance risks
- Batch jobs, integrations, or reports perform unreliably
- Business requirements are difficult to express in standard configuration
- Documentation and automated testing are incomplete
Quality in X++ Work
A strong professional separates configuration from customization and uses supported extension patterns instead of modifying the standard application. They write maintainable X++ code, understand data security and transaction behavior, and test across realistic business scenarios. They can explain trade-offs to functional stakeholders and document changes for future releases. Experience with both new Dynamics 365 environments and older Dynamics AX codebases is valuable when systems are being modernized.
Collaboration and Delivery
X++ projects often combine functional analysis, technical design, data migration, testing, and release management. Remote collaboration works well when requirements, environments, access rules, and acceptance criteria are clearly documented. On-site workshops can help when warehouse, production, or finance processes are difficult to observe remotely. German and English communication may both matter, depending on the users, implementation partner, and delivery team.
Frequently asked questions
What clients ask us most about X++ — answered in short.
X++ is used to customize and extend Microsoft Dynamics 365 Finance and Operations. Professionals use it for ERP logic, workflows, integrations, reports, batch processing, and extensions across finance, supply chain, commerce, and manufacturing.
X++ adds programmatic behavior when configuration cannot meet a requirement. Configuration is usually easier to maintain, while X++ is appropriate for controlled extensions, complex rules, integrations, and specialized processes that must remain inside the ERP.
X++ is the programming language historically used by Microsoft Dynamics AX and still used in Dynamics 365 Finance and Operations. A professional with Dynamics AX experience may understand legacy MorphX customizations, but current projects also require extension-based development in Visual Studio and Lifecycle Services.
X++ work benefits from knowledge of Dynamics 365 data entities, Electronic Reporting, SQL concepts, OData, REST APIs, Azure DevOps, and Power Platform integrations. Functional understanding of finance, procurement, inventory, warehousing, or production is equally important for reliable results.
X++ project needs depend on scope rather than a fixed number of years. A small report or extension may suit a focused specialist, while an upgrade, integration landscape, or manufacturing rollout calls for someone who has handled architecture, testing, deployment, and business coordination.
X++ projects can usually be delivered remotely through controlled environments, documentation, and scheduled workshops. On-site work in Germany can still help with process discovery in warehouses, plants, or finance departments, while German or English communication should match the project team and user groups.
Ask an X++ specialist to explain extension patterns, transaction handling, security, testing, and upgrade impact. Review examples of maintainable code and ask how the person distinguishes configuration from customization before discussing a delivery plan.
A strong X++ freelancer can read older Dynamics AX customizations, trace dependencies, and plan a safe path toward supported extensions. They preserve business continuity while reducing technical debt, improving documentation, and making future updates less risky.
