MB-800 Exam Guide: Business Central Skills, Cost and Plan

The MB-800 exam gives you the Microsoft Certified: Dynamics 365 Business Central Functional Consultant Associate credential. You get 100 minutes, you need a score of 700, and the exam is proctored through Pearson VUE. This guide covers what it tests, what it costs, and how to prepare.

What MB-800 proves and who it is for

Microsoft describes the role this way: a functional consultant implements core application setup processes for small and medium businesses. You configure the application with the implementation team so the business can manage it easily. The official certification page lists the level as Intermediate.

This exam fits you if you set up or support Business Central for a company. It also fits you if you work in finance, sales, purchasing, or inventory and want to prove you can configure the system. Candidates typically have applied experience meeting business requirements. Some specialize in one or more feature areas.

The exam covers these Business Central modules:

• Financial management

• Sales

• Purchasing

• Inventory

• Fixed Assets

It also covers role centers (insights, cues, action tiles, reports, and charts), extensions, and Copilot capabilities, including built-in agents. You should know how Business Central connects with Microsoft 365, Microsoft Power Platform, and Microsoft Dynamics 365.

Exam format at a glance

Microsoft says you may get interactive components. Try the exam sandbox before test day. It uses the same interface as the real exam, so you see the question types in advance.

If the exam is not offered in your preferred language, the study guide says you can request an additional 30 minutes. If you fail, you can retake 24 hours after the first attempt. Wait times for later retakes vary, so read Microsoft's retake policy before you book.

Skills measured and their weights

These weights come from the study guide's skills measured as of June 30, 2026. Microsoft updates the English exam first, so check the guide again before you book.

Operations is tied with financials for the largest weight, so do not treat it as an extra. Below are the setup and financials areas in detail. The operations sub-skills are listed in the official study guide.

Set up Business Central

• Create a company with Assisted Setup, and use configuration worksheets and packages.

• Create journal opening balances and migrate data.

• Manage security: user profiles, permissions, permission sets, security filters, and auditing.

• Set up reports, job queues, number series, and Copilot and agent capabilities.

• Set up dimensions, including global and shortcut dimensions and blocking combinations.

• Set up native workflows and approvals.

Configure financials

• General ledger setup, accounting periods, payment terms, deferrals, currencies, and payment methods.

• Chart of accounts, account categories, and general ledger allocations.

• Posting groups: specific, general, inventory, and general posting setup.

• Journals, batches, bank accounts, and recurring journals.

• Accounts payable and receivable, including how vendor or customer ledger entries relate to general ledger entries.

• Fixed assets: depreciation books, classes and subclasses, and depreciation methods.

What the exam costs

Microsoft publishes the exam price in USD, and it varies by the country or region where you take the exam. As of November 14, 2026, we use the vendor's published USD price for comparison.

The list price comes from Microsoft's official exam price in USD. Check the Microsoft exam page for your own country before you pay anything.

A 6-week study plan with weekly hours

This plan is our suggestion, not Microsoft's. It totals 40 hours and assumes you can open a Business Central sandbox company and click through every setup page. Reading alone rarely works for a configuration exam.

Worked example: splitting 40 hours by weight

Take the midpoint of each range and apply it to 40 hours:

• Set up Business Central, 22.5%: about 9 hours.

• Configure financials, 32.5%: about 13 hours.

• Configure sales and purchasing, 12.5%: about 5 hours.

• Perform Business Central operations, 32.5%: about 13 hours.

The weeks below follow that split. Operations practice is spread across weeks 3 to 6, so you run real transactions while the setup is fresh.

1. Week 1 (5 hours, setup): create a company with Assisted Setup. Build a configuration package. Set up number series, users, and permission sets.

2. Week 2 (4 hours, setup): set up dimensions, default dimensions, and blocking combinations. Build an approval workflow and a job queue entry. Change a report layout.

3. Week 3 (8 hours: 5 financials, 3 operations): configure general ledger setup, accounting periods, currencies, and the chart of accounts. Work through general and specific posting groups. Then post a few general journal entries and check the resulting ledger entries.

4. Week 4 (9 hours: 8 financials, 1 operations): create journal templates, batches, and bank accounts. Set up vendors, customers, and payment journals. Add a fixed asset and compare depreciation methods. Post one vendor payment end to end.

5. Week 5 (8 hours: 5 sales and purchasing, 3 operations): configure inventory, item categories, and units of measure. Run sales and purchase documents from start to finish, then post and review the entries.

6. Week 6 (6 hours: 6 operations and review): run day-to-day transactions in your sandbox from order to payment. Take the practice assessment on AI Skills Navigator, where you must be signed in to launch it. Run the exam sandbox. Redo the labs for your weakest area.

The weeks add up to 9 hours of setup, 13 of financials, 5 of sales and purchasing, and 13 of operations. Operations here includes the hands-on posting in weeks 3 to 5 plus the end-to-end work in week 6.

If you already configure Business Central at work, cut weeks 1 and 2 to a quick review and move those hours to operations. If you are new to accounting, add a few hours in week 3 on how posting groups drive ledger entries.

Common mistakes to avoid

• Skipping the hands-on work. The exam may include interactive components, so memorized answers will not carry you.

• Underweighting operations. At 30–35%, it counts as much as financials.

• Ignoring Copilot and agents. Both the audience profile and the setup skills mention them.

• Learning posting groups as a list. Practice the chain from a posted document to vendor or customer ledger entries, detailed entries, and the general ledger.

• Booking before checking the guide date. Skills measured change, so confirm you studied the June 30, 2026 version.

After you pass: renewal and next steps

The credential expires after 12 months. You renew at no cost by passing an online assessment on Microsoft Learn. Set a calendar reminder a few months ahead so you are not rushing.
