Backorders: Why partial fulfillment creates complexity in Dynamics 365 F&SCM

Backorders are a routine part of any distributor’s operations. If an item isn’t available, you wait for it to come in, then ship it. Simple enough.

But that assumption only holds in a controlled environment. In reality, distributors are dealing with fluctuating inventory levels, unpredictable supply chains, and increasing pressure to meet customer expectations. In that context, backorders become more complicated, especially when only part of an order can be fulfilled.

Partial fulfillment introduces additional dependencies, system behavior, and decisions that aren’t always obvious. And when those aren’t clearly understood or managed, the impact shows up across operations, visibility, and customer experience.

Backorders are just one example of a larger challenge: most distributors operate with processes that don’t fit neatly into standard system logic, even with Dynamics 365 for Finance & Supply Chain Management (F&SCM). To understand where complexity starts, it helps to begin with the simplest version of the process.

The backorder baseline

In an ideal scenario, order fulfillment follows a clean, linear path. A sales order is created, inventory is available, and the order moves through picking, packing, and shipping without interruption. That flow works well, as long as inventory is there to support it.

When inventory is missing or only partially available, the process changes. Instead of a single, continuous workflow, fulfillment becomes fragmented. Some items move forward, while others wait.

So, what happens next?

Where backorders get complicated

Partial fulfillment turns a straightforward process into a multi-step one. Instead of a single transaction, you now have a split outcome: part of the order is shipped, and part remains open. That remaining portion needs to be tracked, released, and fulfilled later, often under different conditions than the original order.

This creates a disconnect between what the system shows and what’s happening operationally. The order is still active, but part of the work is already complete. Managing that gap requires more coordination than many teams expect.

In Dynamics 365 F&SCM, fulfilling backorders—especially for partially fulfilled orders—often involves background processes rather than a fully visible, step-by-step workflow.

These processes monitor inventory, attempt to release remaining quantities, and retry fulfillment based on system logic. While this is designed to handle complexity behind the scenes, it can make it difficult for teams to understand what’s happening in real time.

As a result, questions arise: Has the system tried to release this order? Is it waiting on inventory, or has the process stopped? When will it move forward?

Teams feel like they’re reacting to the system rather than managing it.

Even with planning tools in place, backorders depend on when inventory becomes available, and that timing isn’t always predictable. Vendors may ship inconsistent quantities, lead times may shift, and transportation delays can disrupt well-planned schedules. In many cases, backorders remain open longer than expected, not because of a system issue, but because of the real world.

That unpredictability makes it difficult to provide accurate timelines or confidently prioritize fulfillment for customers.

The operational impact

Backorders are challenging because they don’t live in just one part of the business. They sit across inventory, order management, planning, and warehouse execution. Each of these areas has its own processes, priorities, and data.

That’s why backorder challenges are rarely just about system configuration. More often, they stem from process inconsistencies, limited visibility, and a lack of coordination across teams.

Internal challenges

Teams may struggle to identify which orders are still waiting or determine which ones should be prioritized. Managing backorders often becomes a manual effort, requiring additional time and coordination. Instead of a controlled process, fulfillment becomes reactive.

External challenges

Customers experience the effects of backorder complexity through unclear timelines, partial shipments that lack context, and delays that aren’t communicated proactively. Even when inventory constraints are unavoidable, the absence of clear communication can lead to frustration. In distribution, where reliability matters, that can hurt customer trust.

It’s not just backorders

Backorders are one example of how complexity shows up in inventory management but they’re far from the only one. Most distributors have at least one process that doesn’t fit neatly into standard system logic.

For example:

• Some distributors manage customer-owned or consigned inventory, where product is sold but remains in the warehouse, requiring custom handling to separate ownership from availability.
• Others deal with inconsistent vendor packaging, where case quantities vary from shipment to shipment, making standard unit conversions unreliable.
• In certain industries, operational requirements such as cleanroom handling introduce additional steps that change how inventory moves through the warehouse.

Each of these scenarios creates challenges similar to backorders: They introduce variability, require additional tracking, and often push standard functionality beyond its intended design.

What to do about it

In our experience, distributors that manage backorders or other non-standard processes well don’t necessarily eliminate complexity. They create structure around it.

Let’s return to the backorder example:

Define how the process should work. Teams need to understand when it makes sense to ship partial orders and when it’s better to wait. Without that, decisions vary from order to order, which introduces inconsistency.

Visibility is another critical factor. Distributors that stay on top of backorders tend to monitor them actively, rather than relying entirely on background system processes. Regularly reviewing open orders and identifying delays prevents issues from lingering unnoticed.

It’s also important to align inventory data with planning and execution. Backorders depend on inbound supply, so teams need to know what’s coming in and when. When that information isn’t accurate or accessible, it becomes much harder to manage expectations or make informed decisions.

Ownership plays a role, as well. Backorders are easier to manage when there is a defined process and clear accountability. Assigning responsibility and establishing a regular review cadence helps keep things moving.

Finally, communication matters. In environments where delays are sometimes unavoidable, being transparent with customers by setting realistic expectations and providing updates can make a significant difference.

How Sikich can help

Because non-standard processes vary, there’s rarely a one-size-fits-all configuration for all distributors. In many cases, distributors need to adapt standard Dynamics 365 F&SCM functionality or introduce custom logic to align with how their business operates to fulfill backorders. Success depends on how well the system is aligned with real-world processes and how effectively teams execute against them.

Let’s talk.

At Sikich, we work with distributors to bridge that gap. If backorders or other warehouse processes are creating challenges in your business, we can help.
