Inventory Optimization for Manufacturers in a Modern ERP 

Anyone that has been in inventory optimization knows that there’s always something you seem to have too much of, sitting longer than expected. At the same time, something else runs short at exactly the wrong moment. 

The conclusion many arrive to is to add a little more buffer, just to be safe. But, over time, those buffers stack up. 

What started as a simple precaution turns into a pattern, possibly a really costly one. 

Has Your Inventory Stopped Feeling Predictable? 

Inventory issues tend to be a mix of small inconsistencies that become notable trends over time. Some common examples include: 

• A planner increases safety stock on a critical component because it caused issues last quarter. 

• Purchasing reacts to a recent shortage by placing larger than usual orders. 

• Operations hesitates to rely on stated inventory levels without a second check.  

Conversations about inventory turn into conversations about what might happen instead of what’s actually happening. 

The system still holds the data, but decisions begin to drift away from it. 

How Inventory Management Turns into a Guessing Game 

Inventory planning sits in the middle of several moving parts: demand, production, and supply. When those pieces aren’t fully aligned, it becomes difficult to make confident decisions about what to carry and when. 

Demand signals may lag behind real conditions or reflect outdated assumptions. Production constraints aren’t always visible at the same time inventory decisions are being made. Supply variability adds another layer of uncertainty, especially when lead times fluctuate or suppliers aren’t consistent. 

In many environments, the ERP contains much of this information, but not in a way that naturally comes together for decision-making. Teams are left connecting the dots themselves, often relying on experience to fill in the gaps. 

The Cost of Holding Extra Inventory 

Holding extra inventory can feel like the responsible choice, especially in uncertain environments. It reduces the risk of stockouts and keeps production moving when things don’t go as planned. 

But that safety comes with tradeoffs. 

Excess inventory ties up capital that could be used elsewhere in the business. It introduces costly complexity in storage, handling, and inventory management. Slow-moving or obsolete items quietly accumulate, often going unnoticed until they become a financial issue. 

There’s also a less visible cost: attention. Teams that are fixated on monitoring, adjusting, and explaining inventory positions are not spending as much (if any) time on improving how inventory is managed in the first place. 

What Balanced Inventory Actually Looks Like 

Optimizing inventory should reflect actual demand patterns, not conservative assumptions layered on top of one another. It means production capacity is part of the equation, so materials arrive in a way that supports how work flows. It also means supply variability is accounted for but not overcompensated for. 

When inventory is aligned this way, decisions feel less reactive. Teams aren’t constantly adjusting buffers or second-guessing what they see. Instead, they’re making informed adjustments based on current conditions. 

How Dynamics 365 and Ellipse Solutions Help Bring Inventory Back Into Alignment 

This is where a connected ERP approach makes a difference. 

Microsoft Dynamics 365 brings together demand, supply, and production planning in a shared environment. And as a result, Inventory decisions are no longer made in isolation, rather they’re informed by what’s happening across the business. As demand shifts or production plans change, those updates are visible in a way that supports more timely decisions. 

That visibility reduces the need to rely on excess buffers as a safety net. Teams can respond to changes with more context, rather than compensating for uncertainty ahead of time. 

Ellipse Solutions helps manufacturers make this practical. Inventory management looks different across industries and operations, and there’s no standard model that fits everyone. Ellipse works with teams to align Dynamics 365 capabilities with how inventory is planned, reviewed, and adjusted within the business. 

Inventory Management Shouldn’t Depend on Guesswork 

Uncertainty will always be part of manufacturing. As you are probably well-aware, demand will change and supply will vary.  

But inventory planning doesn’t have to rely on guesswork. 

If your team is consistently compensating with extra stock, or if inventory decisions feel more reactive than intentional, it may be worth stepping back and looking at how well your ERP supports alignment between demand, production, and supply. 

Ellipse Solutions helps manufacturers use Dynamics 365 to create a more connected view of inventory—reducing excess, improving responsiveness, and making inventory decisions easier to stand behind.
