Independent Review of Microsoft Dynamics 365

Microsoft Dynamics 365 (D365) occupies a unique spot in the enterprise software market. It is used by organizations across virtually every industry and geography, scalable enough for some of the world’s largest enterprises and flexible enough to fit higher-growth mid-market companies. But is it the right fit for your organization? As independent advisors with no financial ties to Microsoft, we have seen the good, the bad, and the ugly across hundreds of D365 implementations. This comprehensive review covers the platform’s history, strengths, weaknesses, ecosystem, and the practical considerations every organization should weigh before selecting and implementing D365.

A Brief History of Microsoft Dynamics 365

Microsoft Dynamics 365 originated from a series of acquisitions Microsoft made over the years. The legacy products that fed into D365 include:

• Great Plains (now Dynamics GP)
• Axapta (now Dynamics AX)
• Navision (now Dynamics NAV)

In 2016, Microsoft consolidated its various ERP, CRM, and standalone business applications under the Dynamics 365 umbrella. Today, D365 is a family of solutions that organizations can adopt individually or together. You can start with just CRM and grow into a full ERP footprint, or implement the full suite from the start.

There are two primary editions of D365:

• Finance and Operations (F&O): Designed for larger enterprises and more complex organizations. Often evaluated as an alternative to SAP S/4HANA.
• Business Central: Targeted at small and mid-market businesses. Competes more directly with Oracle NetSuite than with the larger ERP platforms.

The right edition depends on the scale and complexity of your operations, which we explore further in our broader ERP selection and implementation work.

The Strengths of Microsoft Dynamics 365

Familiar Look and Feel

One of D365’s biggest strengths is its traditional Microsoft look and feel. The user experience is intuitive for employees already accustomed to Microsoft 365, SharePoint, Teams, and other Microsoft productivity tools. This familiarity reduces the learning curve and improves adoption, both of which directly affect the success of your organizational change management effort.

Deep Integration With Microsoft Office

D365’s integration with the Microsoft Office platform is unmatched in the ERP market. The integration goes well beyond exporting data to Excel. Users can open, manipulate, and update data directly in Excel and publish it back into Dynamics. Other Microsoft products integrate equally well, including Power BI for business intelligence, Outlook for CRM contact and email management, and Teams for collaboration. For organizations already committed to the Microsoft ecosystem, this level of integration is one of the most compelling reasons to choose D365.

Flexibility and Open Architecture

D365’s flexibility is a defining strength. Configuring workflows to meet specific business needs is straightforward, and the platform’s open architecture makes it relatively easy to integrate with third-party systems. Compared to less flexible products like SAP S/4HANA, this configurability gives D365 a significant advantage for organizations that need to tailor processes to their unique operations.

User-Friendly Interface and Personalization

D365 offers a more integrated system feel than ERP platforms that resemble websites. Users can customize their own views, set up personal dashboards, and even publish those customized views for broader team use. For example, a customer service manager can create a tailored view with specific columns and share it across the entire customer service team, ensuring everyone is working from the same information.

Comprehensive End-to-End Coverage

D365 covers the full spectrum of business processes: CRM, ERP, sales, customer service, operations, financials, and more, all within a single platform. While Independent Software Vendor (ISV) extensions may be needed for specialized functionality, the breadth of native coverage means most business needs can be met within the D365 ecosystem.

The ISV Model

The Microsoft Independent Software Vendor (ISV) ecosystem is a significant strength. Third-party vendors build tailored solutions on top of D365 that address industry-specific needs. For example, in the government sector, Tyler Technologies has built specialized solutions on the D365 platform that meet the unique requirements of public-sector organizations. This ISV network opens up tailored options that may not be readily available with other ERP systems. The trade-off is that businesses must carefully evaluate ISV solutions to make sure they fit without introducing unnecessary complexity.

The Weaknesses of Microsoft Dynamics 365

The Dark Side of Flexibility

D365’s flexibility is also one of its biggest risks. Just because you can change the software easily does not mean you should. Many of the clients we work with fall into the trap of over-customizing the system, often because employees are reluctant to change how they work. The result is technical debt, instability, and an implementation that becomes harder to maintain and upgrade over time.

In many of these cases, customization is not really a technology problem. It is a symptom of unaddressed change management. Recognizing customization requests as a potential signal of resistance, rather than a pure technical requirement, is one of the most valuable shifts in perspective a transformation team can make.

Maturity Gaps in Some Functional Areas

Like many ERP vendors migrating legacy on-premise functionality to the cloud, D365 still has maturity gaps in certain functional areas. While GP, AX, and NAV had decades of development behind them, D365 is a younger platform, and not all of the advanced functionality from the legacy products has been brought over.

Common gap areas include:

• Product Lifecycle Management (PLM)
• Human Capital Management (HCM)
• Some advanced manufacturing capabilities

For organizations whose operations depend heavily on these functions, it is worth carefully evaluating whether D365 can support them natively or whether ISV extensions will be required.

Cloud Maturity

D365 was not born in the cloud. It started as an on-premise solution and evolved into a cloud platform later than competitors that were cloud-native from day one. The cloud version has matured significantly, but organizations that need the full depth of the on-premise functionality should verify that what they rely on has been brought into the cloud product.

The Reseller and Partner Network Problem

D365’s reseller and partner network is arguably the product’s biggest weakness. Microsoft takes a more open approach to managing its partner ecosystem than other major ERP vendors, which means the market includes a wide range of providers. Some are highly competent. Others lack the necessary expertise to deliver a successful implementation.

Choosing the right Microsoft Dynamics 365 implementation partner is arguably an even more important decision than choosing D365 itself. A weak partner can compromise even the strongest product.

How to Choose the Right D365 Implementation Partner

Because the partner network is uneven, partner selection deserves as much rigor as software selection. Here are the criteria that matter most.

Assess the Competencies of the Partner

Your integrator is only as good as the team members they actually assign to your project. Evaluate their skills in:

• Microsoft Dynamics 365 (specific to the modules you are implementing)
• Project management and program governance
• Business process design and reengineering
• Organizational change management
• Quality assurance and risk mitigation

If gaps exist, plan to fill them with a third-party firm that brings the missing competencies.

Look for Past Experience With Projects Like Yours

Your organization is unique. Ensure the partner has worked with companies that share your industry, culture, scope, and complexity. This prevents your consultants from learning on the job or delivering a generic solution that does not fit. Pay particular attention to product experience as well. D365 is broad, and a partner experienced in finance may not have depth in supply chain, manufacturing, or POS.

Take the Partner’s Estimates With a Grain of Salt

Microsoft Dynamics 365 partners typically have no incentive to be conservative in their proposed timelines and budgets. This is one of the reasons most D365 implementations take more time and money than originally estimated. Look for critical activities missing from the partner’s plan, especially organizational change management and implementation readiness. Plan to fill those gaps with internal resources or independent third-party expertise.

Plan for Organizational Change Management Separately

Most D365 partners are focused exclusively on system functionality, not on the human side of the transformation. Yet change management is one of the most important determinants of success. Identify strong change management resources, whether internal or external, and assign clear ownership. This work should not be left to a partner whose core competency is software configuration.

Establish a Strong Quality Assurance Process

Regardless of which partner you choose, your implementation will carry meaningful risk. Independent quality assurance reduces that risk by providing objective oversight of the partner’s work, the project plan, and the readiness for go-live. This is one of the most effective investments an organization can make in protecting a D365 implementation.

Implementation Challenges to Plan For

D365 implementations come with predictable challenges. Planning for them upfront, ideally during Phase Zero planning, prevents most of the surprises that derail less-prepared projects.

• Complexity of implementation: The high degree of customization possible in D365 means implementation is genuinely complex. Each configuration decision affects others, requiring deep understanding of the organization’s needs.
• Heavy client engagement required: D365’s flexibility demands significant client involvement throughout the project. Without active participation, the system will not be configured optimally.
• Training and user adoption: The platform’s flexibility means users need to understand how to navigate and use it effectively. Strong training and change management strategies are essential.
• Managing scope creep: Extensive customization options can lead to scope creep as new features get continuously added. Strict project management practices keep this in check.
• Integration challenges: Even though D365 integrates well, connecting it with legacy systems still requires careful planning, middleware, and testing.
• Customization maintenance: Customizations need ongoing maintenance, particularly when D365 releases updates that affect them.
• Total cost of ownership: License fees, implementation, training, maintenance, and integration all need to be budgeted realistically from the start.

Is D365 a Good Fit for Your Organization?

Whether D365 is the right choice depends on your business goals, priorities, and ecosystem. It is often a strong fit when:

• Your organization is already invested in the Microsoft ecosystem
• You need a flexible, configurable platform rather than a highly standardized one
• You have growth ambitions and need a platform that scales with you
• You need strong CRM and ERP capability within a single ecosystem
• You can commit to active client involvement throughout implementation

It may not be the right fit when:

• You need highly mature functionality in PLM, HCM, or advanced manufacturing
• You require tight standardization and limited customization
• Your team lacks the bandwidth for deep engagement during implementation
• You need a cloud-native platform with no on-premise legacy

The decision should be made based on fit with your business, not on vendor pressure or industry momentum. When we advise clients on this decision, we always start with a clear understanding of business priorities and let those drive the technology evaluation.

Questions We Hear Most

What Is the Difference Between D365 Finance and Operations and Business Central?

Finance and Operations is built for larger, more complex organizations with sophisticated functional needs. It is the version most often evaluated against SAP S/4HANA and Oracle Fusion Cloud. Business Central is designed for small and mid-market organizations with simpler requirements. It is closer in fit and price to Oracle NetSuite. The right choice depends primarily on organizational scale, transactional volume, and the complexity of your operations.

How Important Is the Implementation Partner Compared to the Software Itself?

More important, in our experience. The same D365 platform can produce vastly different outcomes depending on who implements it. A weak partner with a strong product is a far worse combination than a strong partner with a less perfect product. This is why partner selection deserves rigorous evaluation and why independent quality assurance is one of the most valuable investments organizations can make in a D365 project.

Can You Start With D365 CRM and Add ERP Later?

Yes. D365’s modular structure is designed to support this kind of phased adoption. Many organizations start with the CRM components to address immediate sales or customer service needs, then add Finance and Operations or Business Central as they expand the scope. This phased approach reduces risk and lets the organization absorb change at a manageable pace.
