Decoding the ERP Dilemma

Dynamics 365 Business Central vs.
Finance & Supply Chain Management

4 Myths About Dynamics 365 Business Central vs. Dynamics 365 F&SCM Dispelled 

Many mid-size to large businesses wonder why they should choose Dynamics 365 Business Central over Dynamics 365 Finance & Supply Chain Management (F&SCM, formerly “Dynamics 365 Finance & Operation”) or vice versa. Whether you’re currently on Dynamics GP or Dynamics NAV (QuickBooks or Acumatica… or PeachTree!?), it’s crucial to assess your specific needs and essential features before making a choice. There is a common belief that D365 F&SCM is the better choice due to its extensive features, while Business Central is often underestimated or overlooked. However, this is not entirely true, bigger isn’t always better… Business Central has unique strengths that make it a great fit for certain businesses, despite the rich features of F&SCM. Microsoft doesn’t heavily market Business Central, and the distinction between which type of business is better suited for BC versus F&SCM is unclear. But do not fear, we’re here to debunk these misconceptions and provide guidelines to help you make an informed decision. 

With 600+ years of combined Dynamics consulting experience, and over 1500 ERP implementations, Technology Management Concepts can provide more clarity and guidance in your decision-making process. So, let’s dive into the comparison between Dynamics 365 Business Central and Dynamics 365 Finance & Supply Chain Management!

Myth #1  

“If my company has over 100 users, I need D365 F&SCM!” 

Although Microsoft advertises Dynamics 365 F&SCM to “larger” organizations, it does not necessarily mean it is more suitable for you if you have more than what is considered a “small” organization. There are many companies with 500 users that are operating on Business Central such as Coca-Cola, US Postal Office, Michelin, and Johnson & Johnson.

In fact, if you’re concerned with the performance, Microsoft’s Principal Software Engineer, Christina Heide Damm debunks this myth by explaining that capacity is rarely a performance problem in Business Central, because there’s always a 40% buffer in the VM to create more VMs to handle the usage and allow you to scale with the data activity.  The main reason for slow performance is due to AI code and how it is using the database queries. Additionally, users can self-troubleshoot when this happens.

Obviously, there are other factors to consider aside from scalability, but if you are solely concerned with the number of users to make your decision, it is important to note the requirements that come with that number of users and whether BC or F&SCM can adequately meet those needs. 

Myth #2

“If I have many 3rdparty products with my ERP right now, going to F&SCM will allow me to have everything configured in one product” 

Just because F&SCM offers a comprehensive set of features, it does not mean it’ll replace or replicate all the functionalities provided by your third-party solutions. Most companies will still require multiple third- party products to enhance their ERP to fit their specific needs or they’ll need to do deeper customizations to fit those requirements.  

In addition, replacing all your third-party products with equivalent functionalities within F&SCM may involve additional licensing costs and ongoing maintenance expenses. Business Central offers a more cost-effective option as it allows you to retain your existing third-party products and only integrate as needed.  

It is important to also note that Business Central is generally considered to be more customizable compared to F&CSM, as it is designed to be highly flexible and adaptive, which will make it easier to configure your third-party products that have extensive customizations.


Myth #3 

“If I have multi-currency, multi-language requirements, I need F&SCM” 

Microsoft’s marketing efforts often highlight F&SCM’s global features and its built-in localization functions for various countries, however Business Central also offers both multi-currency and multi-language capabilities through localization, customization, and integration options 

Business Central offers currency management, exchange rate calculations, multi-language document templates, and language-specific reporting. 


Myth #4 

“My company is making over $100 million in revenue that means I need D365 F&SCM” 

There is a perception that as a company grows in terms of revenue, it also becomes more complex in its operations and has more extensive processes. However, it does not automatically necessitate the implementation of F&SCM. Each business is unique in its scenario, and the selection of an ERP system should be based on a thorough analysis of specific business requirements, operational complexity, industry dynamics, and growth plans, rather than relying solely on revenue figures.  

Also note that there have also been many publicly traded companies with $1 billion+ in revenue that are running on Business Central such as Johnson & Johnson, XPO Logistics, and Stanley Black & Decker


Indicators to Consider When Choosing Between D365 BC and F&SCM

Microsoft’s 1/3 rule is a simple way to help you assess whether your business needs a more comprehensive, but complex solution like Dynamics 365 F&SCM or a simpler solution like Dynamics 365 Business Central. 

However, it is important to note that the 1/3 rule is just a guideline. The best way to choose the right ERP solution for your business is to consult with a Microsoft partner like Technology Management Concepts, who can assess your specific needs and recommend the best solution for you
