TL;DR
MB-800 tests whether you can configure Dynamics 365 Business Central for a small or mid-size business, not whether you can write code for it. Four domains: setup (20-25%), financials (30-35%), sales and purchasing (10-15%), and day-to-day operations (30-35%). Passing score is 700/1000. The exam has no formal prerequisite — Microsoft expects applied, hands-on experience with the product instead. Study each domain in the Business Central web client itself, not just in slides, because the questions describe configuration scenarios you have to reason through.

As a candidate for Microsoft's official exam page (checked September 7, 2026)puts it, you implement Dynamics 365 Business Central: configuring the core application, creating companies, migrating data, and collaborating with an implementation team so the business gets a system it can actually use. Business Central is Microsoft's cloud ERP for small and mid-size companies that have outgrown basic accounting software — distinct from Dynamics 365 Finance or Supply Chain Management, which target larger, more complex enterprise operations.
Microsoft does not publish an exact question count or time limit on a per-exam basis, and MB-800's official pages don't list one either — so this guide doesn't invent a number. What Microsoft does confirm is the domain breakdown below, straight from the MB-800 study guide.
Set Up Business Central
20-25%This domain is where an implementation actually starts: a new company shell, security, dimensions for reporting, and the approval workflows that keep transactions honest.
- • Create a company using Assisted Setup, then build a configuration worksheet and configuration package to move settings and master data between environments
- • Create journal opening balances and migrate data to and within Business Central
- • Manage security: user profiles, permission sets, security filters, security groups, and security auditing
- • Set up core functionality: report layouts, job queues, number series, and Copilot/agent capabilities
- • Set up dimensions and dimension values, global vs. shortcut dimensions, default dimensions for master data and account types, dimension priorities, and blocked dimension combinations
- • Configure approval workflows: native workflows, notification setup, and workflow user groups
Where candidates lose points: global dimensions vs. shortcut dimensions. Global dimensions are baked into every posting and are expensive to change later; shortcut dimensions 3-8 are easier to add after go-live but don't appear on as many standard reports and filters. A scenario question that asks "which dimension type should be used for a reporting requirement discovered after go-live" is testing exactly this trade-off.
Configure Financials
30-35%The heaviest domain, and the one that underpins everything else in Business Central — a mistake in posting group setup surfaces months later as a reconciliation problem.
- • Configure general ledger setup, accounting periods, payment terms, deferrals, currencies/exchange rates, and payment methods
- • Manage the chart of accounts: account categories and subcategories, financial reporting by category, and general ledger allocations
- • Set up posting groups: specific and general posting groups, general and inventory posting setup, and allowing multiple posting groups
- • Set up journals and bank accounts: bank accounts, journal templates and number series, batches, and recurring journal templates
- • Set up accounts payable and receivable: vendor and customer accounts, Purchases & Payables and Sales & Receivables setup, payment/cash receipt journals, payment registration, and the relationship between ledger entries and detailed ledger entries
- • Configure fixed assets: depreciation books, fixed asset classes/subclasses, main assets and components, and depreciation methods
Where candidates lose points: general posting groups vs. specific posting groups. General posting groups (business + product) decide which G/L accounts a transaction hits; specific posting groups (customer, vendor, inventory) apply on top of that. Questions describing "a transaction posted to the wrong revenue account" are almost always a general posting group combination, not a specific one.

Start Free Practice →Configure Sales and Purchasing
10-15%The smallest domain by weight, but it's where inventory setup decisions ripple into every purchase order and sales order processed later.
- • Configure inventory setup, core item settings (item categories, attributes, units of measure, item variants), locations, and stockkeeping units
- • Understand the relationship between items, item ledger entries, value entries, and general ledger entries, and differentiate between costing methods
- • Configure master data for sales and purchasing: shipping agents, shipping addresses, vendor order addresses and lead times, and locations
- • Manage pricing and discounts: vendor purchase prices, purchase line/invoice discounts, customer sales prices, and sales line/invoice discounts
Where candidates lose points: costing methods. FIFO, LIFO, Average, Standard, and Specific each change what "item cost" means at the moment of posting versus at adjustment. A scenario about a company wanting cost to reflect the exact unit received (e.g., serialized high-value items) is describing Specific costing, not Average — a distinction that trips up candidates who memorized definitions without applying them.
Perform Business Central Operations
30-35%Tied with Financials for the largest weighting. This domain tests the daily-use functional consultant skills: running the actual documents through the system, not just setting it up once.
- • Perform basic tasks: designing/customizing/personalizing pages, filters, finding documents and related entries, Edit in Excel, and data analysis mode
- • Process purchases and sales: quotes, orders, receiving/shipping, over-receipts, reversing receipts/shipments, recurring lines, blanket orders, and deferrals
- • Process financial documents: purchase/sales invoices and credit memos, combining shipments/receipts into a single invoice, correcting posted invoices, releasing/reopening documents, and prepayment invoices
- • Process journals and payments: payment journals, cash receipt journal, payment registration, applying/undoing applied ledger entries, bank reconciliation, recurring journals, general ledger allocations, exchange rate adjustments, and the Dimension Correction Tool
- • Process fixed asset transactions: acquisitions, depreciation, and disposals
- • Process inventory transactions: receipts, shipments, transfers between locations, cost adjustment, counting, and reclassification
Where candidates lose points: the Dimension Correction Tool is new-ish to many study plans and gets skipped. It lets you fix dimensions on already-posted entries without reversing them — know that it exists and when you'd reach for it instead of a full reversal, because "correct a posted entry with the wrong dimension" is a recognizable question shape.
How to Split Your Study Time
A weighting percentage isn't a study-hour percentage on its own — some domains take longer to get comfortable with per point of exam weight because they involve more distinct pages and settings. Here's a reasonable split for a 40-hour study budget, weighted toward the two heaviest domains but padding Setup slightly because dimensions and security trip up candidates coming from other Dynamics 365 apps.
| Domain | Exam Weight | Suggested Hours (of 40) |
|---|---|---|
| Set Up Business Central | 20-25% | 9 hours |
| Configure Financials | 30-35% | 13 hours |
| Configure Sales and Purchasing | 10-15% | 5 hours |
| Perform Business Central Operations | 30-35% | 13 hours |
Do the reading in Microsoft's Business Central documentation alongside a trial or sandbox company — MB-800 questions describe configuration scenarios inside specific pages, and reading about a setting is not the same as having clicked through it. Once you've worked a domain in the product, run our MB-800 practice questions for that domain before moving to the next one, rather than saving all practice for the end.
If you already work with Business Central day to day, shift hours away from Setup and toward whichever of Financials or Operations you touch less often in your current role — most functional consultants specialize in one feature area on the job, and MB-800 expects familiarity with all of them. If you're coming from a different Dynamics 365 app (Finance, Supply Chain Management, or Customer Service), don't assume the terminology transfers: Business Central's posting groups, dimensions, and page names are its own, not a re-skin of the Finance and Operations platform those exams cover.

Check My ReadinessQuestions About the MB-800 Exam
What does the MB-800 exam actually cover?
Four skill areas, per Microsoft's official study guide (skills measured as of June 30, 2026): Set up Business Central (20-25%), Configure financials (30-35%), Configure sales and purchasing (10-15%), and Perform Business Central operations (30-35%).
What is the passing score for MB-800?
700 out of 1000, the same scaled threshold Microsoft uses across its role-based associate exams.
How much does the MB-800 exam cost?
Microsoft's exam FAQ states Associate and Expert-level exams typically cost $165 USD, adjusted for local currency and tax. MB-800 is Associate level, so budget for that rate rather than the Fundamentals-level price.
Are there formal prerequisites for MB-800?
No formal prerequisite exam is listed. Microsoft's audience profile describes applied experience implementing and configuring Business Central's financial management, sales, purchasing, and inventory modules instead.
Does MB-800 cover AL extension development or coding?
No. MB-800 is scoped to functional configuration. Writing AL code and building extensions belongs to the separate MB-820: Business Central Developer exam — a different credential for a different role.
Does the MB-800 certification expire?
Yes, every 12 months. Renewal is a free online assessment through Microsoft Learn — you do not retake the full paid exam.
Which Business Central module should I study first?
Start with Configure financials. General ledger setup and posting groups underpin nearly every transaction tested later in the operations domain, so getting financials solid first makes the rest of the material click faster.
How is MB-800 different from MB-230, MB-310, and MB-330?
All four are Dynamics 365 functional-consultant exams, but they don't share a product. MB-800 is Business Central, the cloud ERP built for small and mid-size companies. MB-230 (Customer Service), MB-310 (Finance), and MB-330(Supply Chain Management) are built on the separate, larger Dynamics 365 Finance and Operations platform aimed at bigger enterprises. The underlying application, page layouts, and even the terminology differ enough that studying one won't meaningfully prepare you for another.
