What is the MB-800 Microsoft Dynamics 365 Business Central Functional Consultant Associate exam?
MB-800 is an Microsoft certification exam for people who configure and support Dynamics 365 Business Central. Business Central is Microsoft's cloud ERP system built for small and medium-sized businesses. Passing this exam earns the Microsoft Certified: Dynamics 365 Business Central Functional Consultant Associate credential.
The exam is aimed at functional consultants and implementers, not developers. It checks whether you can set up a Business Central environment and configure the core modules that a typical company needs to run its day to day operations. This includes finance, sales, purchasing, and inventory.
Many candidates come to this exam after working on live Business Central projects, often through a Microsoft partner. The certification is a way to show a client or employer that you understand the platform beyond the basics.
How much does the MB-800 Microsoft Dynamics 365 Business Central Functional Consultant Associate exam cost?
Microsoft charges $165 for the MB-800 exam voucher when you buy it directly. Cyber VK sells the same official voucher for $44.99, a saving of $120.01, which works out to 73% off the official price.
The voucher from Cyber VK is the same Microsoft product you would get anywhere else. It is not a discount code or a trial. You use it to book your exam through the normal Microsoft exam scheduling process, at a test center or online.
If you want to buy the voucher, you can do that on the MB-800 exam voucher page.
What is on the MB-800 Microsoft Dynamics 365 Business Central Functional Consultant Associate exam?
The exam covers five domains. Each one maps to a part of Business Central that a functional consultant is expected to configure.
| Domain | What it covers |
|---|---|
| Business Central | Setting up companies, users, and the base configuration of a Business Central environment |
| Finance | Configuring the general ledger, budgets, bank accounts, and financial reporting |
| Sales | Setting up customers, sales processes, and sales order handling |
| Purchasing | Setting up vendors, purchasing processes, and purchase order handling |
| Inventory | Managing items, item tracking, and warehouse and stock control |
The exam has 60 questions to answer in 2 hours 30 minutes. You need a score of 700 (on 100 to 1000 scale) to pass.
How hard is the MB-800 Microsoft Dynamics 365 Business Central Functional Consultant Associate exam?
MB-800 is an associate level exam, so it sits between entry level and expert. It expects hands on familiarity with Business Central, not just reading about the product.
The time pressure is real but manageable. With 60 questions in 2 hours 30 minutes, you get a reasonable amount of time per question if you know the material. People who struggle usually have not spent enough time actually configuring the modules in a live or trial environment.
The finance domain carries the most weight, so gaps in your finance knowledge will cost you more than gaps elsewhere. Sales, purchasing, and inventory are closely related in practice, so understanding how a document flows from sales order to shipment, or purchase order to receipt, helps across several domains at once.
How to prepare for the MB-800 Microsoft Dynamics 365 Business Central Functional Consultant Associate exam
A simple week by week plan works well for most candidates. Adjust the length to fit your current experience with Business Central.
- Week 1: Get access to a Business Central trial or sandbox and walk through basic company setup.
- Week 2: Work through the finance domain. Set up a chart of accounts, post journal entries, and run financial reports.
- Week 3: Work through sales and purchasing. Create customers, vendors, sales orders, and purchase orders end to end.
- Week 4: Work through inventory. Set up items, check stock levels, and post inventory transactions.
- Week 5: Review weaker domains and try the free MB-800 practice questions on Cyber VK.
- Week 6: Do a final review of all domains and book your exam once you feel ready.
If you already work with Business Central day to day, you can likely compress this into 4 weeks by skipping straight to review and practice questions.
Common mistakes people make
Some candidates focus only on one module they use at work, such as sales, and skip finance because it feels less familiar. Since finance carries a large share of the exam, this is a costly gap.
Others study the theory but never open a live or trial system. Business Central questions are scenario based, so you need to know what a screen actually looks like and what steps a task takes, not just the name of the feature.
A third common mistake is booking the exam before doing any practice questions. Practice questions show you how the questions are phrased and where your knowledge is thin, so it is worth doing this before you commit to a date.
Is the MB-800 Microsoft Dynamics 365 Business Central Functional Consultant Associate certification worth it?
MB-800 is the main associate certification for anyone whose job is implementing or supporting Business Central. If you already work as a functional consultant on Business Central projects, the certification is a direct match for your day to day work and worth pursuing.
Cyber VK also sells vouchers for other Microsoft associate and expert exams, including AZ-204 Microsoft Azure Developer Associate, DP-203 Microsoft Azure Data Engineer Associate, PL-300 Microsoft Power BI Data Analyst Associate, MB-330 Microsoft Dynamics 365 Supply Chain Management Functional Consultant Associate, PL-200 Microsoft Dynamics 365 Customer Experience Analyst Associate, Customer Experience Edition, SC-100 Microsoft Cybersecurity Architect Expert, AB-900 Microsoft Copilot and Agentic AI Fundamentals, and MB-920 Microsoft Dynamics 365 Fundamentals ERP. If you work across the wider Dynamics 365 or Power Platform stack, these are worth considering alongside MB-800.
For someone new to ERP work in general, MB-800 is still a reasonable place to start, since Business Central is one of the more widely deployed ERP systems in the small and medium business market. Just make sure you get real hands on time with the product before you sit the exam.
