Dynamics GP vs Business Central – Which is Right For You?

My Past with Great Plains, Present and Future with Business Central

To give you some context, my journey with Microsoft Dynamics began back in 2008 as a GP partner. For several years, the focus was on helping clients implement and optimize their GP manufacturing solutions.

Around 2013, there was a noticeable shift in the market. NAV (now known as Business Central) was gaining popularity, and GP partners found themselves losing deals to those that offered NAV as a solution. Since then, we have fully embraced Business Central.

Recently, Microsoft announced that support for GP will end in 2029. This end-of-life announcement means that while the software won’t stop working immediately, it will continue to work for years to come. That said, there will be no further updates or official support from Microsoft after that date.

This is truly an opportune time for GP users to explore alternative ERP solutions to ensure long-term stability and growth.

Dynamics GP vs Business Central: Feature Comparison

At the core, both GP and Business Central are robust ERP solutions that offer full manufacturing capabilities. However, there are some key differences worth highlighting to help you understand what an upgrade from GP to Business Central manufacturing might mean for your business.

I am biased because I really like Business Central, but I tried to be honest with the ratings that I put in here. Generally speaking, GP and BC are fairly close in feature sets. Frankly, GP might be slightly more feature-rich.

Other Sales & Purchasing Differences

Business Central introduces several differences in its sales and purchasing processes compared to GP. For example, Business Central does not have a separate batching system—when you post a sales or purchase order, it posts directly without any intermediary batching.

Similarly, the concept of a distinct “backorder” document doesn’t exist in Business Central. Instead, any sales order with remaining quantities is treated as open, allowing for adjustments and tracking directly in the system. This aligns with how most traditional ERP systems handle back orders, whereas GP is unique in generating a separate back order document.

Business Central replaces GP’s segmentation concepts with Dimensions, offering more flexibility for categorizing data. The role of site segments, specifically, is filled by Responsibility Centers, which provide a comparable yet streamlined functionality. Lastly, Business Central has a stronger focus on warehouse fulfillment processes, enabling you to efficiently send shipment releases to the warehouse—an improvement over GP’s handling of similar distribution tasks.

Now that we know what features are in both systems and how they compare, what about the features that are unique to each system?

Engineer-to-Order (ETO) and Project Manufacturing

Engineer-to-order (ETO) and project manufacturing in Business Central are tailored for dynamic and flexible production processes. These scenarios often involve selling a product before its bill of materials (BOM) is fully defined, relying on high-level, long-lead-time components. This approach blends aspects of GP’s project management and manufacturing modules, but Business Central takes it further with its integrated project management features.

In GP, managing ETO could involve using projects to track costs but without BOM integration, or leveraging manufacturing orders for purchasing and production while sacrificing project-specific tracking. Business Central solves these limitations by offering “project tasks” (formerly “jobs”) that combine the best of both worlds. Planning lines in Business Central function as dynamic BOMs, allowing users to create purchase orders directly against the project, link assemblies, and track subcontractor costs. This structure also supports detailed comparisons of estimated versus actual costs, a feature that’s difficult to replicate in GP without workarounds.

Moreover, Sabre ETO enhances Business Central’s ETO capabilities with BOM import features and deeper manufacturing integration, making it a game-changer for project manufacturers transitioning from GP.

Dynamics GP vs Business Central

Sales and Production Order Integration

In GP, integrating sales orders with manufacturing orders involves SOP-MOP connections that generate linked documents, either manually or automatically. Business Central mirrors this functionality with its planning module, which links production orders to sales orders. While the overall process is similar, Business Central offers added flexibility through its MRP module, which provides real-time production suggestions based on order-level demand and inventory availability.

One standout feature of Business Central is its “capable to promise” functionality, which surpasses GP’s basic “available to promise.” Capable to promise analyzes all BOM components, lead times, and MRP rules to calculate an accurate delivery date. This makes it invaluable for manufacturers dealing with complex BOMs or multi-level assembly structures. While GP’s approach to order integration is functional, Business Central’s tools provide greater precision and efficiency, particularly for businesses requiring advanced planning capabilities.

Bills of Materials (BOM) and Routings

Both GP and Business Central offer strong support for BOMs and routings, but each system has its nuances. In GP, BOMs are tied to specific items, with options for regular, phantom, and effective-dated parts. Business Central takes a more flexible approach, allowing BOMs to exist independently of items. For example, multiple items (e.g., red, blue, and green variants) can share the same BOM, reducing duplication.

One area where Business Central excels is its native Excel integration, enabling users to mass update or upload BOMs with ease—a task that is cumbersome in GP. Additionally, Business Central supports multiple active BOM versions and status tracking for design, review, or engineering phases. On the other hand, GP’s routings include convenient features like combining labor and machine time on a single line, which Business Central requires separate entries for. However, Business Central compensates with robust ISV add-ons for shop floor data collection, further enhancing its capabilities for modern manufacturing environments.

Material Requirements Planning (MRP)

Dynamics GP MRP is a bucketed system, meaning it calculates requirements for predefined time periods (e.g., weekly buckets). This approach, while traditional, can be less precise. In contrast, Business Central uses a bucketless MRP system that calculates requirements on a daily basis. This means that orders are planned for the exact dates they are needed, leading to more accurate scheduling and inventory management.

Business Central’s MRP is also more user-friendly, offering a simplified requisition worksheet for straightforward purchasing and a full planning worksheet for advanced scenarios, including MRP and MPS. While GP’s MRP is powerful, it can be challenging to set up and use effectively. Business Central provides an easier learning curve and better feature integration, making it a superior choice for most manufacturers.

Advanced Manufacturing Features

Business Central includes unique features that enhance its manufacturing capabilities. For example, the “value entry” system ensures accurate cost tracking across all layers of production, adjusting inventory values dynamically as items are consumed, subcontracted, or sold. This level of cost accuracy is unmatched in GP.

Another innovative feature in Business Central is the simulated production order, which allows manufacturers to create mock orders for quoting purposes. Additionally, Business Central supports production families, enabling co-products or by-products to be produced from a single routing—ideal for industries like automotive or injection molding. GP lacks direct equivalents for these features, highlighting Business Central’s more modern approach to manufacturing management.
