Most businesses work with external accounting professionals whether it’s a CPA who prepares your taxes, a bookkeeping firm that helps with monthly closings, or financial consultants who provide periodic guidance. These outside professionals often need access to your financial data to do their work effectively. But should you pay for additional Business Central licenses just so your accountant can review your books a few times a year?
Microsoft recognized this common need and built a solution directly into Business Central: the External Accountant license. This complimentary license gives your outside accounting professionals appropriate access to your Business Central data without requiring you to purchase additional user licenses.
This guide will help you understand what the External Accountant license includes, who should use it, how to set it up, and how to make the most of this valuable feature that comes included with your Business Central subscription.
What Is the External Accountant License?
The External Accountant license is a special type of Business Central access designed specifically for accounting professionals who work with your business but aren’t your employees. These licenses are provided at no additional charge with every Business Central subscription, recognizing that businesses routinely need to share financial information with their CPAs, bookkeepers, and financial advisors.
Every Business Central subscription automatically includes three External Accountant licenses. You don’t need to purchase them separately, request them specially, or pay anything extra. They’re simply part of your subscription, ready to use whenever you need to give an outside accounting professional access to your system.
The External Accountant license is structured as a named user license, meaning you assign it to a specific individual accountant or accounting professional. That person can then access your Business Central environment from any device, their office computer, laptop, tablet, or smartphone just like your internal users.
What Makes External Accountant Licenses Special?
External Accountant licenses are unique in several important ways that make them particularly suited for outside professionals.
First, they’re complimentary. Unlike other Business Central licenses that require monthly subscription payments, External Accountant licenses come included with your Business Central subscription at no extra charge. You get three of them automatically, which typically covers most businesses’ needs for external accounting support.
Second, they’re designed for non-employees. These licenses are specifically intended for professionals who work with your company but aren’t part of your organization. This includes your CPA firm, outside bookkeeping services, tax preparers, financial consultants, and auditors. Because they’re designed for external users, they include appropriate safeguards and limitations.
Third, they provide comprehensive financial access. External Accountants get extensive access to all your financial data and reports, which is exactly what they need to prepare taxes, review your books, provide financial advice, or complete audits. They can see everything necessary to do professional accounting work.
Fourth, they include important security boundaries. While External Accountants have broad access to financial information, they cannot access administrative functions or other sensitive areas that should remain under your internal control. This balance provides necessary access while maintaining appropriate security.
What Can External Accountants Do?
Understanding the capabilities of the External Accountant license helps you know what to expect when you give your accounting professional access to your Business Central system.
1. Complete Financial Data Access
External Accountants have full access to all financial information in your Business Central system. They can view your entire chart of accounts, see all account balances and transaction details, review general ledger entries from any period, and access historical financial data. This comprehensive access ensures they can perform their professional work without constantly asking you to pull reports or export data.
They can access all your financial reports including profit and loss statements, balance sheets, cash flow statements, trial balances, and any custom financial reports you’ve created. They can also view budget information, see budget versus actual comparisons, review budget allocations, analyze spending patterns against budgets, and provide advice on budget management.
For accounts payable and receivable, External Accountants can review vendor invoices and payment history, see customer invoices and payment status, check aging reports for both payables and receivables, analyze cash flow based on payment patterns, and identify potential collection issues or opportunities for payment optimization.
2. Bank Reconciliation and Cash Management
External Accountants can work with your banking information to help with reconciliation and cash management. They can view bank account information and transactions, perform bank reconciliations, review reconciliation history, identify unreconciled items, and help resolve discrepancies. This capability is particularly valuable during monthly or quarterly closings when timely reconciliation is crucial.
3. Fixed Asset Management
If your business tracks fixed assets in Business Central, External Accountants can access all related information. They can view your fixed asset registry, review depreciation schedules and calculations, see acquisition and disposal information, check depreciation methods and useful life assumptions, and analyze fixed asset values for financial reporting purposes.
4. Cost Accounting and Allocation
For businesses using cost accounting features, External Accountants can access cost centers, analyze cost allocations, review cost accounting reports, evaluate profitability by cost center or department, and provide recommendations for cost management.
5. Multi-Company Access
If your Business Central subscription includes multiple companies or entities, External Accountants can access all of them with a single license. This is particularly useful if your accounting firm works with a business group that has multiple legal entities, all of which need consolidated reporting or tax preparation.
6. Period Closing and Financial Statements
External Accountants can assist with period closing activities by reviewing period-end adjustments, verifying closing entries, checking for open items that should be closed, validating financial statement preparation, and confirming that all necessary transactions are recorded before closing a period.
7. Tax Preparation Support
Since many businesses use External Accountant licenses for their tax preparers, these licenses provide appropriate access for tax-related work. External Accountants can review tax-related transactions and reports, access information needed for tax return preparation, verify deductible expenses and taxable income, review sales tax or VAT reporting, and gather documentation needed for tax filings.
8. Analytics and Business Intelligence
External Accountants can access Business Central’s reporting and analytics tools to run standard financial reports, create custom report views for specific analysis, use drill-down capabilities to investigate details, export data to Excel for additional analysis, and provide insights based on financial trends they observe.
What Can’t External Accountants Do?
While External Accountant licenses provide extensive financial access, they intentionally exclude certain capabilities to maintain appropriate boundaries between external professionals and internal management.
1. No Administrative Access
External Accountants cannot access user management functions. They can’t create or modify user accounts, change user permissions or security settings, assign licenses to users, or manage password policies and security settings. System administration remains firmly in the hands of your internal team or your IT partner.
They also cannot configure system settings, modify company information or preferences, change integration settings with other systems, alter workflow configurations, or adjust system-wide defaults. These administrative controls ensure that outside professionals can’t inadvertently or intentionally change how your system operates.
2. Limited Access to Non-Financial Areas
External Accountant licenses focus on financial information. While they can view information connected to financial transactions, they have limited access to operational areas. They typically cannot manage sales orders or customer relationship activities beyond what’s necessary to understand financial implications, process purchase orders or manage vendor relationships except as related to financial obligations, control inventory operations or warehouse management, or access service management or manufacturing modules.
This limitation makes sense because external accountants generally don’t need to run your operations they need to understand the financial results of those operations.
3. No Transaction Creation in Most Areas
External Accountants can view financial data extensively, but their ability to create or modify transactions is carefully controlled. They generally cannot create sales invoices or purchase orders, post inventory transactions, enter new customer or vendor master records, or initiate operational transactions. This read-focused access with limited write capabilities ensures they can review and analyze your finances without making changes to operational data.
4. No Access to Certain Sensitive Applications
External Accountants cannot access other Business Central applications beyond their external accountant role. This means they can’t access your full Business Central environment beyond what the External Accountant license specifically permits, use features reserved for full internal users, or access administrative applications and setup functions.
Who Should Get External Accountant Licenses?
Identifying the right professionals for External Accountant licenses ensures you’re using this valuable resource appropriately.
1. Your CPA Firm
Your certified public accountant or CPA firm is the most common recipient of External Accountant licenses. If your CPA prepares your annual tax returns, they need access to detailed financial information throughout the year. An External Accountant license lets them review your books periodically, pull necessary reports, verify transaction details, and gather everything needed for tax preparation without you having to export and send files repeatedly.
If your CPA provides compilation or review services, they can access your financial statements directly, review supporting details, verify account balances, and complete their professional work efficiently. For audit services, while auditors may have different access requirements, External Accountant licenses can support certain audit activities by giving auditors direct access to financial records and supporting documentation.
2. Bookkeeping Services
Many businesses outsource some or all of their bookkeeping to external firms. If you work with an outside bookkeeping service that helps with monthly closings, they can use an External Accountant license to review your financial transactions, identify needed adjustments, verify account reconciliations, and ensure your books are ready for management review.
If your bookkeeping service handles specialized tasks like sales tax preparation and filing, they can access the necessary reports and transaction details, verify tax calculations, review taxable and non-taxable transactions, and prepare required filings.
3. Financial Consultants and Advisors
Business financial consultants often need access to detailed financial information to provide valuable advice. If you work with a consultant who provides strategic financial planning, they can use an External Accountant license to analyze your financial trends, review historical performance, compare actual results to projections, and develop recommendations based on real financial data.
For consultants helping with cash flow management, direct access to Business Central lets them review receivables and payables aging, analyze cash flow patterns, identify opportunities for improvement, and provide timely advice based on current financial position.
4. Interim or Part-Time Controllers
Some businesses hire fractional CFOs or part-time controllers who aren’t full-time employees. If these professionals work with multiple clients and spend limited time with your organization, an External Accountant license might be appropriate for their needs. They can review financial performance, monitor key financial metrics, provide oversight on financial operations, and offer strategic guidance without requiring a full user license.
5. Tax Specialists
If you work with tax specialists beyond your general CPA perhaps for sales tax compliance, international tax matters, or specialized tax credits External Accountant licenses give them appropriate access. They can review relevant transactions, access specific reports needed for tax compliance, verify calculations and reporting, and gather documentation for tax filings or credits.
6. Business Valuation Professionals
When you need business valuation services for estate planning, mergers and acquisitions, or other purposes, valuation professionals can use External Accountant licenses to access historical financial statements, review revenue and expense trends, analyze asset values and liabilities, and gather data needed for valuation calculations.
How to Set Up External Accountant Access
Giving your accounting professional access through an External Accountant license involves a straightforward process, but understanding the steps helps ensure smooth setup.
1. Inviting Your External Accountant
The process begins in Business Central with the invitation feature. You’ll navigate to the External Accountant setup area in Business Central, enter your accountant’s email address, provide their name and contact information, and send the invitation. Business Central generates an automated welcome email sent to your accountant that includes instructions for accessing your environment, a verification process for security, and information about getting started.
Your accountant receives this welcome email and follows the instructions to verify their identity, set up their access, and log into your Business Central environment for the first time. This secure process ensures that only the intended professional gets access to your financial data.
2. Managing External Accountant Users
Once set up, External Accountant users appear in your Microsoft 365 admin center in a special category. You can see who has External Accountant access, view when they last accessed your system, manage their permissions within the External Accountant role, and remove their access when it’s no longer needed.
It’s important to understand that External Accountant users are different from regular Microsoft 365 users in your organization. They’re specifically designated as external users, which means they appear separately in your user management, have different permission structures, can access only what the External Accountant license permits, and don’t count against your regular user licenses.
3. Security and Access Control
When you give someone External Accountant access, you’re maintaining good security practices. You should communicate clearly about what they can and cannot access, set expectations about data confidentiality, establish when and how often they’ll need access, and determine how long their access should remain active.
Many businesses review External Accountant access periodically to ensure only current professionals have active access, access rights align with current business relationships, no unused licenses are left active unnecessarily, and security practices remain appropriate.
4. Working with Multiple Accounting Professionals
Remember that you get three External Accountant licenses with your subscription. If you work with multiple professionals, you can assign each their own license. For example, you might give one license to your CPA firm for tax preparation, another to your bookkeeping service for monthly support, and a third to a financial consultant for strategic planning. Each professional gets their own login and appropriate access without interfering with the others.
If you need more than three External Accountant licenses, you can discuss options with your Cloud Solution Provider, though three licenses typically accommodate most businesses’ needs for external accounting support.
Making the Most of External Accountant Licenses
Getting maximum value from External Accountant licenses requires some thought about how you’ll use them.
1. Clear Communication with Your Accountant
When you first give your accountant access, take time to explain what’s available. Show them how to log in and navigate Business Central, point out where key reports and information are located, explain any custom reports or views you’ve created, and clarify what they can and cannot do with their access. This upfront investment in communication saves time and confusion later.
Discuss how they prefer to work. Some accountants want to log in and pull what they need independently. Others prefer to have you generate certain reports for them. Understanding their work style helps you support them effectively while they have External Accountant access.
2. Establishing Regular Access Patterns
If your accountant needs regular access perhaps monthly for bookkeeping review or quarterly for tax planning establish a routine. Let them know when information will be ready for their review, ensure necessary transactions are recorded before their scheduled review time, close periods appropriately before they begin their work, and be available to answer questions about specific transactions or unusual items.
This routine helps your accountant work efficiently and helps you ensure your books are ready for their professional review.
3. Document Sharing and Collaboration
While External Accountants have extensive access to your financial data, sometimes additional documentation is needed. Establish how you’ll share supporting documents like bank statements, receipts for unusual transactions, explanations for adjustments, or documentation for specific line items. Many businesses use shared folders, email, or document management features in Business Central to keep everything organized.
4. Period Closing Collaboration
If your accountant helps with period closing, coordinate the process carefully. Determine who makes closing entries, establish who posts final adjustments, clarify when periods should be closed, and decide how closing documentation will be handled. Clear roles and responsibilities ensure smooth monthly or quarterly closings without duplication or confusion.
5. Tax Season Preparation
If your accountant prepares your taxes, External Accountant access can streamline tax season significantly. Throughout the year, ensure your books are kept current so your accountant can review them at any time, close periods promptly so financial statements are available, flag unusual transactions with explanatory notes, and keep supporting documentation organized. When tax season arrives, your accountant can access everything they need directly rather than waiting for you to prepare and send extensive information packages.
6. Ongoing Value from External Relationships
External Accountant access isn’t just about convenience it can improve the quality of professional advice you receive. When your accountant has direct access to your current financial data, they can provide more timely advice, identify issues or opportunities quickly, answer questions based on real-time information, and offer proactive guidance rather than reactive problem-solving.
This ongoing access can transform your relationship with external accounting professionals from periodic reporting exercises into continuous advisory relationships that add real value to your business.
Common Questions About External Accountant Licenses
1. How many External Accountant licenses do we get?
Every Business Central subscription includes three External Accountant licenses at no additional charge. This typically accommodates most businesses’ needs for external accounting professional access.
2. Can we assign an External Accountant license to someone who’s not really an accountant?
External Accountant licenses are specifically intended for external accounting professionals CPAs, bookkeepers, financial consultants, and similar professionals who provide accounting services to your business. Using them for other purposes goes against the licensing terms and isn’t appropriate.
3. What happens if our accountant leaves or we change accounting firms?
You can easily revoke an External Accountant’s access when the relationship ends. Simply remove their user access through your Microsoft 365 admin center or Business Central user management. You can then assign that External Accountant license to your new accounting professional.
4. Can External Accountants access our system anytime, or only when we give permission?
Once you grant External Accountant access, that professional can log in whenever they need to, just like your internal users. If you want to restrict when they can access your system, you’ll need to manage that through communication rather than technical controls. If you need to temporarily prevent access, you can disable their account and re-enable it when appropriate.
5. Do External Accountants see everything our regular users see?
External Accountants see all financial data but have limited access to operational areas and no access to administrative functions. They have a specialized view of Business Central focused on what accounting professionals need.
6. Can we upgrade an External Accountant license to a full user license?
External Accountant licenses are a separate license type designed specifically for external professionals. If someone becomes an employee who needs full system access, they would need a regular Business Central license rather than an External Accountant license.
7. How do we know when our External Accountant accesses our system?
Your IT administrator or system manager can review access logs to see when External Accountants log in and what they access. This audit trail ensures appropriate oversight of external access.
Security Considerations for External Accountant Access
While External Accountant licenses provide valuable access to outside professionals, maintaining good security practices is important.
1. Verify Professional Credentials
Before granting External Accountant access, verify that the individual is indeed a qualified accounting professional. Confirm their credentials, verify they have a legitimate business relationship with your company, ensure they understand confidentiality obligations, and establish clear terms for their access to your data.
2. Confidentiality and Professional Standards
Professional accountants are bound by ethical standards and confidentiality requirements. However, it’s still good practice to discuss expectations explicitly, document confidentiality obligations, clarify what they can and cannot share, and establish professional boundaries. Most accounting professionals take these obligations seriously, but clear communication prevents misunderstandings.
3. Regular Access Reviews
Periodically review who has External Accountant access to your system. Verify that all active External Accountant users still need access, confirm that business relationships are still active, remove access for professionals you no longer work with, and ensure no licenses are sitting unused. This regular housekeeping maintains security and ensures you’re using your available licenses appropriately.
4. Data Backup and Recovery
While External Accountants generally only view and analyze data rather than making extensive changes, maintain good backup practices. Ensure regular backups of your Business Central data, test recovery procedures periodically, maintain audit trails of changes made, and have processes for reviewing and verifying any adjustments made by external users.
5. Communication About Sensitive Matters
If your business is involved in sensitive matters pending litigation, potential mergers or acquisitions, confidential strategic initiatives discuss with your external accountant what information they should and shouldn’t access, whether any special confidentiality measures are needed, and how to handle particularly sensitive financial information.
The Bottom Line
The External Accountant license is a valuable feature included with your Business Central subscription that facilitates productive relationships with external accounting professionals. By giving your CPA, bookkeeper, or financial consultant direct access to your financial data, you eliminate the constant back-and-forth of report requests, data exports, and file sharing.
Your accounting professionals can work more efficiently when they have direct access to the information they need. You save time by not having to prepare and send information packages. And the quality of professional advice often improves when advisors can see real-time financial data rather than relying on periodic snapshots you provide.
With three External Accountant licenses included automatically, you have the flexibility to work with multiple professionals, perhaps your CPA for tax work, a bookkeeper for monthly support, and a consultant for strategic planning. Each gets appropriate access without you having to purchase additional licenses.
The key is using these licenses appropriately for qualified external accounting professionals and managing them with good security practices. When used correctly, External Accountant licenses represent significant value included in your Business Central subscription.
