Microsoft Dynamics 365 Business Central Developer (MB-820) – Complete Exam Information
Who Should Take This Exam
The MB-820 is designed for developers who work with Business Central or want to start. You’re a good fit if you’re a software developer moving into the ERP space, a NAV developer upgrading your skills to Business Central, a functional consultant who wants to add development expertise, or an IT professional responsible for customizing Business Central systems. You don’t need years of experience, but you should be comfortable with programming concepts and object-oriented thinking.
This certification helps developers who want to specialize in ERP solutions, consultants looking to command higher rates, and anyone building a career in the Microsoft ecosystem. Business Central skills are in demand because companies constantly need developers who can customize their ERP systems.
MB-820 Exam Structure and Format
The MB-820 exam costs $165 USD, though prices vary by country. You’ll have 100 minutes to complete the test. The passing score is 700 on a scale of 100-1000, which works out to about 70%.
The exam includes multiple question types: standard multiple choice, multiple select (choose all that apply), drag-and-drop code ordering, case studies with several related questions, and hotspot questions where you select parts of code or interface elements. Some questions give you partial AL code and ask you to complete it correctly.
Microsoft updates the exam regularly, and the most recent update went live on June 10, 2025. Always check the official study guide for the latest changes.
Exam Domains and Skills Measured
Here’s exactly what the exam covers, based on the official Microsoft study guide:
- Describe Business Central (10-15%)
This section tests your understanding of Business Central’s architecture and components. You need to know the difference between the base app and system app, understand how extensions work versus classic customizations, and explain Business Central’s update lifecycle. You’ll answer questions about online versus on-premises deployments, the AppSource publishing process, and how Business Central fits into the larger Microsoft ecosystem. People often underestimate this section, but it’s foundation knowledge that shows up in later questions.
- Install, develop, and deploy for Business Central (10-15%)
Here you’ll work with development environment setup, Visual Studio Code configuration, and AL extension management. Questions cover debugging techniques, deployment processes, managing multiple extensions in one workspace, and handling multilanguage development. You need hands-on experience setting up a development environment, not just theoretical knowledge. Expect questions about launch.json configuration and workspace management.
- Develop by using AL objects (35-40%)
This is the biggest chunk of the exam. You’ll need to build and extend tables, pages, and reports. Questions cover different page types (Card, List, Document), Role Center design, enum creation, report substitution, and XMLport configuration. You’ll work with permission sets, entitlement objects, installation codeunits, and upgrade codeunits. The query object section tests your ability to aggregate data, join data items, and use queries instead of record variables. This section separates people who actually code from those who just read about it.
- Develop by using AL (15-20%)
This section digs into AL programming itself. You’ll customize the UI experience with profiles and views, implement user assistance models, create teaching tips and onboarding checklists, and use assisted setup. You need to understand Business Central’s data process model, including document standards and master data patterns. Questions cover AL procedures, data types, file management, error handling, and access modifiers. You’ll write code snippets that manipulate data correctly and handle exceptions properly.
- Work with development tools (10-15%)
You’ll work with the Test Toolkit, develop test codeunits, and write test procedures. Telemetry questions cover how to configure monitoring, analyze signals in Application Insights, and create custom telemetry for your extensions. This section often trips up developers who don’t work with production systems, so make sure you understand telemetry patterns.
- Integrate Business Central with other applications (10-15%)
The final section covers REST API integration using HTTP classes, JSON handling, creating and working with Business Central APIs, and implementing OData bound and unbound actions. You’ll see questions about Read Scale-Out for performance optimization. Integration is critical for modern Business Central implementations, so Microsoft tests this thoroughly.

Cost and Requirements
The exam costs $165 USD when you register through Pearson VUE. There are no formal prerequisites – you don’t need other certifications first. However, Microsoft recommends at least six months of hands-on Business Central development experience before attempting the exam.
If you fail, you can retake it after 24 hours. Your certification is valid for one year, then you’ll need to renew it by passing a free online assessment on Microsoft Learn. This keeps your certification current as Business Central evolves.
Why MB-820 Certification Matters in 2026
The MB-820 certification opens real career opportunities because Business Central is growing fast. Small and mid-sized businesses are moving to cloud ERP systems, and Business Central is Microsoft’s primary offering for that market. Companies need developers who can customize it.
Business Central developers in the United States earn an average of $110,387 per year, with entry-level positions starting around $90,000 and senior roles reaching $150,000 or more. Top earners can make up to $195,231 annually. These numbers reflect strong demand and limited supply of qualified developers.
The certification proves you understand AL programming, extension development, and Business Central architecture. It shows employers and clients you can handle real projects, not just talk about them. Many consulting firms require this certification for their Business Central developers.
Beyond salary, the MB-820 gives you flexibility. You can work as an internal developer for companies using Business Central, join a Microsoft partner as a consultant, freelance on implementation projects, or specialize in specific industries like manufacturing or distribution. The certification is your entry ticket to all these options.
Business Central continues evolving with new features every release wave. Certified developers stay current with these changes and can command premium rates for their expertise. In 2026, skills in Power Platform integration, AI features, and cloud-native development are especially valuable additions to your core Business Central knowledge.
Proven Study Strategies for MB-820 Success
Start with a realistic timeline. If you’re already a developer with some Business Central exposure, plan for 8-10 weeks of focused study. Complete beginners should budget 12-14 weeks. Don’t try to cram this exam – the practical knowledge takes time to sink in.
- Week 1-2: Build Your Foundation
Get your development environment set up correctly. Install Visual Studio Code, the AL extension, and connect to a Business Central sandbox. Work through the basic Microsoft Learn modules to understand Business Central architecture. Don’t skip this even if it seems basic – the exam tests these concepts.
- Week 3-6: Deep Practice with AL Objects
This is where you actually code. Create table extensions, build pages, write codeunits with event subscribers, and design reports. Build at least one complete mini-project that uses multiple object types. Our PassITExams practice questions work perfectly here because they give you realistic scenarios to practice.
- Week 7-8: Integration and Testing
Work with APIs, practice reading and writing JSON, and get comfortable with the Test Toolkit. Set up Application Insights for your sandbox and learn to read telemetry. These topics often get neglected but they’re critical for the exam.
- Week 9-10: Practice Tests and Weak Spots
Take full-length practice exams with PassITExams. Track which domains you’re weak in and focus your remaining time there. Review every wrong answer to understand why you missed it. Time yourself to get used to the 100-minute limit.
Study Tips That Actually Work:
- Code every day, even if it’s just 30 minutes. Consistency beats marathon sessions.
- Use the Visual Studio Code debugger constantly. The exam tests your ability to troubleshoot.
- Join the Business Central community forums and read discussions about common problems.
- Practice explaining concepts out loud. If you can’t explain it simply, you don’t understand it well enough.
- Review the official GitHub samples for Business Central development patterns.
- Don’t just memorize syntax – understand when to use each AL object type and why.
Resources to Use: Start with PassITExams materials as your core study tool. Add the official Microsoft Learn paths for Business Central development. Use the Microsoft documentation for reference when you hit something confusing. The Business Central developer community on GitHub has excellent code samples you can study and modify.
What Not to Do: Don’t just read study guides without coding. You’ll fail. Don’t skip the sections that seem boring (like telemetry) – they’re on the exam. Don’t rely solely on your work experience if you’ve only touched one area of Business Central. The exam covers the whole platform.

Frequently Asked Questions About MB-820
How hard is the MB-820 exam really?
It’s moderately challenging. If you’ve coded in AL before and understand Business Central basics, you’ll find it manageable with good preparation. Complete beginners need to put in more work. The exam tests practical skills, not just memorization, so hands-on practice matters more than cramming facts. Most people who fail did so because they skipped the coding practice and tried to memorize their way through.
How long does it take to prepare for MB-820?
Most developers need 8-12 weeks of focused study. If you’re already working with Business Central, you might cut that to 6-8 weeks. Beginners should plan for 12-14 weeks. Don’t rush it – building actual coding skills takes time. Studying 1-2 hours daily works better than weekend marathons.
Can I pass MB-820 without Business Central experience?
Technically yes, but it’s much harder. You’ll need to be disciplined about practicing in a sandbox environment and coding every scenario yourself. PassITExams materials help, but you also need to actually build extensions, not just read about them. If you have general programming experience, you can learn Business Central while studying for the exam – just give yourself enough time.
What’s the best way to use PassITExams dumps?
Start by taking a diagnostic test to find your weak spots. Then study those domains using our PDF materials and code along with the examples. Take practice tests weekly to track progress. In your final two weeks, do full-length timed practice exams daily. Review every wrong answer thoroughly – that’s where the real learning happens.
Are PassITExams questions similar to the real exam?
Yes, very similar. Our questions come from recent exams, so you’ll see the same question types, difficulty level, and topic coverage. Many candidates report seeing questions on the actual exam that closely match our practice materials. That’s because we continuously update based on real exam feedback.
What if I fail the MB-820 exam?
You can retake it after 24 hours. Use that time to review your exam score report, which shows which sections you struggled with. Focus your restudy efforts there. If you studied with PassITExams and still failed, contact us for a refund under our money-back guarantee. But honestly, most people pass on their second attempt if they used quality materials the first time.
How much does the MB-820 cost total?
The exam itself costs $165 USD. PassITExams materials are much less expensive than traditional training courses while being more effective. Budget around $200-250 total for the exam and study materials. That’s a small investment considering the salary increase you’ll get with certification.
Do I need to know C/AL from old NAV versions?
No. The MB-820 focuses entirely on AL programming in modern Business Central. C/AL is legacy technology. If you know C/AL, some concepts will feel familiar, but the exam doesn’t test it. You need to learn AL syntax and modern extension development patterns.
What’s the difference between MB-820 and MB-800?
MB-800 is for functional consultants who configure Business Central without coding. MB-820 is for developers who write AL code and build extensions. They’re completely different roles. Developers need MB-820. If you want both perspectives, take both exams, but start with the one that matches your actual job.
Can I take MB-820 online from home?
Yes, through online proctoring with Pearson VUE. You’ll need a webcam, stable internet, and a quiet space. The online option is convenient, but make sure your setup meets all technical requirements before test day. Some people prefer testing centers because there are fewer technical issues.
How often does Microsoft update the MB-820 exam?
Microsoft updates certification exams regularly, usually once or twice a year. They add new features as Business Central evolves and remove outdated content. Always check the official study guide before scheduling your exam. PassITExams keeps our materials updated with these changes automatically.
Will this certification help me get a job?
Yes. The MB-820 proves you have real Business Central development skills. Many Microsoft partners require it for their consultants. Even if it’s not required, it makes your resume stand out. Combine it with actual project experience, and you’ll be a strong candidate for Business Central developer positions.
