- MB-310 is Microsoft's exam for the Dynamics 365 Finance Functional Consultant Associate credential, delivered by Pearson VUE in 100 minutes.
- Financial management is the heaviest domain at 35-40%, so it deserves the most preparation time.
- Passing requires a scaled score of 700, not a raw percentage of correct answers.
- The skills measured update on August 14, 2026, removing cost management and adding budget planning.
What Is MB-310, Exactly?
MB-310 is the exam code Microsoft assigns to the Microsoft Certified: Dynamics 365 Finance Functional Consultant Associate certification. It is not a generic finance credential and it is not issued by a third-party training organization - it comes directly from Microsoft Corporation and is proctored through Pearson VUE. If you've seen the acronym "MB-310" attached to a different kind of certification elsewhere, that is a different exam entirely; this article, and this site, deal exclusively with the Dynamics 365 Finance version.
At its core, MB-310 validates that you can configure, implement, and support the financial management components of Microsoft Dynamics 365 Finance - the ERP module that handles general ledger, accounts receivable, accounts payable, budgeting, and fixed assets for mid-size and enterprise organizations. Passing the exam earns you the "Associate" title, a credential that sits on Microsoft's official certification ladder alongside other Dynamics 365 functional consultant paths.
Who Pursues the MB-310 Credential
The people who sit MB-310 are usually already working around ERP systems in some capacity. That includes functional consultants configuring Dynamics 365 Finance for clients, accountants and finance analysts transitioning into systems-facing roles, and implementation partners who need a Microsoft-recognized credential to staff client projects. Organizations that deploy Dynamics 365 Finance often look for this certification specifically when hiring or promoting consultants, because it signals hands-on familiarity with the exact modules - ledger, receivables, payables, budgeting, fixed assets - that a live implementation touches.
If you're weighing whether the certification maps to real hiring demand or fits your career plans, the deeper breakdown in MB-310 Jobs and the analysis in Is the MB-310 Certification Worth It?

Inside the Exam Experience
MB-310 is a proctored exam lasting 100 minutes, and Microsoft notes it may include interactive components - meaning some questions go beyond simple multiple choice and ask you to manipulate a simulated interface or sequence steps correctly. This matters for pacing: interactive items typically take longer to work through than a standard multiple-choice question, so time management across the full 100 minutes is part of what's being tested, not just your accounting knowledge.
Two logistics details catch candidates off guard:
- Breaks consume exam time. If you step away during the exam, the clock keeps running - there's no pause on the 100-minute allotment.
- No returning to reviewed questions after a break. Once you've viewed a question and then take a break, you cannot go back to revisit it. This changes how you should approach flagging items for later review.
Microsoft also permits limited access to Microsoft Learn content during eligible role-based exams like MB-310, but this is restricted - it is not unrestricted web browsing, it doesn't extend your time, and it's meant as a narrow reference tool rather than a research shortcut. Treat it as a safety net, not a study substitute.
Key Takeaway
Budget your 100 minutes assuming interactive items will slow you down, and avoid taking breaks until you're certain you won't need to revisit earlier questions.

The Five Domains You're Tested On
MB-310's content is organized into five functional domains, each carrying a different weight in the overall exam. Understanding these weights should directly shape how you allocate study hours.
Domain 1: Implement Financial Management (35-40%)
This is the largest domain by a wide margin and covers the core general ledger configuration that everything else in the system depends on.
- Chart of accounts, financial dimensions, and ledger setup
- Journals, allocations, and consolidation configuration
- Financial reporting structures
Domain 2: Implement Accounts Receivable, Credit, Collections, and Subscription Billing (15-20%)
Covers the customer-facing money-in side of the ledger, including newer subscription billing capability.
- Customer invoicing and free text invoices
- Credit limits and collections processes
- Subscription billing configuration
Domain 3: Implement and Manage Accounts Payable and Expenses (10-15%)
Focuses on the vendor and employee-expense side of the ledger.
- Vendor invoice processing and payment configuration
- Expense management setup
- Vendor-related workflows and approvals
Domain 4: Manage Budgeting (10-15%)
Budget planning was added to the skills measured as of the August 14, 2026 update, replacing the previous cost-management objective.
- Budget register entries and budget control
- Budget planning configuration
- Budget cycle setup
Domain 5: Manage Fixed Assets (10-15%)
Covers the lifecycle of capital assets inside the ledger.
- Fixed asset acquisition and depreciation profiles
- Asset disposal and transfers
- Integration between fixed assets and the general ledger
For a line-by-line breakdown of sub-topics within each of these five areas, MB-310 Exam Domains 2026: Complete Guide to All 5 Content Areas goes deeper than the summary above.
| Domain | Weight | Primary Focus |
|---|---|---|
| Implement financial management | 35-40% | Ledger, dimensions, journals, consolidation |
| Accounts receivable, credit, collections, subscription billing | 15-20% | Customer invoicing, credit, collections |
| Accounts payable and expenses | 10-15% | Vendor invoicing, payments, expense reports |
| Manage budgeting | 10-15% | Budget control, budget planning |
| Manage fixed assets | 10-15% | Acquisition, depreciation, disposal |
How the 700 Passing Score Actually Works
MB-310 uses Microsoft's scaled scoring system, and the passing threshold is 700. That number does not mean you need 70% of questions correct - it's a scaled result where different questions can carry different weight depending on difficulty and domain. Some candidates assume they can calculate exactly how many questions they're allowed to miss, but because of the scaling and the mix of interactive items, that kind of arithmetic doesn't hold up reliably.
The practical implication is that you should study to a level of genuine competence across all five domains rather than trying to game a percentage. MB-310 Passing Score 2026: Exactly What You Need to Pass unpacks the scoring mechanics in more detail if you want the full explanation.
What Background You Need Before Sitting
Microsoft recommends candidates have accounting knowledge along with hands-on experience implementing Dynamics 365 Finance before attempting MB-310. This isn't a formal prerequisite in the sense of a required course, but it reflects reality: the exam's scenario-based and interactive questions assume you've actually configured ledgers, processed vendor and customer transactions, or worked through a budget cycle inside the application - not just read about it.
If you're coming from a pure accounting background without system exposure, or a systems background without accounting depth, expect a steeper climb on whichever side is unfamiliar. MB-310 Requirements 2026: Eligibility, Prerequisites & How to Qualify lays out how to close either gap before exam day.
Keeping the Credential Current
Once earned, the MB-310 certification is valid for 12 months. Microsoft doesn't require you to retake the full proctored exam to keep it active - instead, renewal happens through a free, online, unproctored, open-book assessment that becomes available during the six months before your certification expires.
A few details matter here:
- Successful renewal extends your validity one year from the existing expiration date, not from the day you complete the renewal assessment.
- The renewal assessment's objectives differ from the initial exam blueprint - it's testing whether you've kept pace with product changes, not re-testing the original five domains verbatim.
- Because it's open-book and unproctored, it's designed as a knowledge refresh rather than a second high-stakes exam.
Mapping Study Time to the Domains
Because Implement financial management carries 35-40% of the exam, it deserves the largest share of your calendar - not an equal fifth alongside the other four domains. A reasonable way to sequence preparation is to front-load the general ledger and dimension work first, since concepts there resurface inside receivables, payables, and fixed assets later.
Financial Management Foundations
- Chart of accounts, financial dimensions, ledger setup
- Journals, allocations, and consolidation
Receivables and Payables
- Customer invoicing, credit, collections, subscription billing
- Vendor invoicing, payments, expense management
Budgeting and Fixed Assets
- Budget register entries and budget planning
- Fixed asset lifecycle and depreciation profiles
Timed Practice
- Full-length practice runs under a 100-minute clock
- Review flagged weak areas across all five domains
Since the skills measured update on August 14, 2026 removes the cost-management objective and adds budget planning, make sure whatever materials you're studying from reflect that change - outdated guides may still emphasize cost management. A structured week-by-week plan built specifically around the current blueprint is laid out in MB-310 Study Guide 2026: How to Pass on Your First Attempt, and a condensed reference for last-minute review is available in MB-310 Cheat Sheet 2026: One-Page Review of Must-Know Facts.
Running realistic timed questions on the main practice test platform before exam day is one of the more effective ways to get comfortable with the interactive question format and the 100-minute pacing described earlier in this article. Working through a full MB-310 practice test set also helps surface which of the five domains still needs attention before you commit to a testing date.
