Best practice for inventory management: Gaining control over inventory without adding complexity

Introduction: the key role of inventory management

Inventory management is at the very heart of every chain of supply. The best way to get a handle on inventory management is quite plain: keep track of your stock levels, where it all is, and what status it's in, so your team can act with confidence as they put deals into place. Get it right and everything just clicks into place. Get it wrong and problems will soon start to show up.

Too much stock ties up cash and puts a strain on the whole cash flow operation.
Too little stock brings operations to a grinding halt. And if your planning is poor you'll struggle to meet customer demand and you may even miss sales.
Bad data just leads to bad decisions.

That's why organisations just keep coming back with the same question. What are the best ways to manage inventory, and how do you put them into practice in real life?

This blog takes a close look at the best ways to manage inventory in practical terms, covering inventory management strategies and inventory control from basic principles right through to the day to day action on the warehouse floor. For medium to large enterprises in manufacturing, warehousing, retailing, and distribution using SAP or planning a SAP S/4HANA migration, the focus is on accuracy, process design, inventory visibility, stock movement control, cycle counting, reducing complexity, multi site operations, and data quality, because these are the disciplines that protect supply chain performance, warehouse efficiency and cash flow. We'll also explore how the PreBilt inventory management functionality makes good practice a reality in SAP environments every single day.

Defining what are the best ways to manage inventory

Now what do we mean by the best ways to manage inventory?

The best ways to manage inventory aren't about striving for perfection. They're about control, visibility and doing things in a consistent way.

At a basic level, good inventory management means:

• You know what inventory items you've got and you're maintaining the right stock levels

• You know where it all is

• You know its status and condition

• You trust the inventory data and the inventory records enough to act on them

Effective inventory control depends on having a clear inventory management plan and the right inventory system or inventory management system.

The problem isn't understanding these principles. Its applying them on a big scale, across different sites, teams and systems.

Start with accuracy, not reports

Accuracy comes first before even thinking about real time inventory reports

One of the most common mistakes in inventory management is to focus on reports before you've actually got the accuracy right.

The best practice for inventory management starts on the warehouse floor, not in a dashboard. If stock movements aren't recorded correctly in the first place, then no amount of reporting will sort it out later. Real time inventory tracking gives you up to date visibility into stock levels.

That's why best practice focuses on:

• Keeping your inventory up to date in real time

• Validating things at the point where the action is taking place

• Cutting back on manual keying wherever possible

PreBilt supports this by taking users through inventory transactions step by step. Scans are validated. Errors are flagged up early. The right data flows back into SAP automatically to strengthen your inventory tracking.

Regular audits help identify any discrepancies in your inventory records, so accuracy comes first and then insight follows.

Get processes to match real life warehouse operations

Processes have to work on the shop floor, not just on paper.

Inventory processes often look neat and tidy on paper, but they just don't work out in practice. So good warehouse management has to match the real world and support efficient business operations.

Best practices for inventory management realise that:

• Warehouses are busy and physical environments

• Users are short on time

• Decisions get made quickly

Warehouse workers shouldn't have to work round the system. The processes need to fit the reality of the job, not the other way round.

PreBilt inventory management functionality is built around tasks, not transactions. Users don't need to understand SAP movement types or menu paths. They're guided through receiving, movements, picking and counting in a way that supports day to day inventory operations and better stock control on the floor.

That should also reflect the whole production process as raw materials and finished goods move through operations.

That reduces the need for training, speeds up execution and improves adoption.

Keep inventory visible, without overwhelming teams

Inventory visibility is a must for operational efficiency. But more data doesn't always equal better visibility.

Best practice inventory management is about:

• Clear stock status

• Meaningful exceptions

• Confidence in what you're seeing

Teams don't need to see everything all the time. Monitoring inventory performance and a few key performance indicators helps identify inefficiencies. They need to see what matters.

By making sure the inventory data is accurate at the point of execution, PreBilt helps SAP give clearer and more reliable inventory visibility. That makes it easier to trust what you're seeing, make faster and better-informed decisions, and support customer satisfaction if things start to change.

Inventory control: keeping stock movement simple and under control

Uncontrolled stock movement is one of the biggest causes of inventory inaccuracy.

The best practices for inventory management include:

• Defining simple putaway and movement rules that support stock control

• Clear location strategies

• Validating item and location combinations for efficient stock control

PreBilt makes sure these rules get followed in real time as things get moved around, checking to make sure the right item is going to the right place, in the right condition.

That prevents all sorts of problems from happening in the first place, like moving the wrong items or storing too much stock, rather than having to clean up afterwards.

Prioritising cycle counting over annual stock takes

Annual stock takes can be a real pain and seem expensive, and by the time they're finished the numbers are probably already out of date.

Experts in inventory management generally agree that:

• Regular cycle counting is the way to go

• You should also use risk based count strategies on your high value items

• And keep on top of things through continuous reconciliation

Regular audits help you spot discrepancies in your inventory records and should inform your safety stock calculations to keep costs down. Keeping some safety stock on hand with the right levels can act as a buffer against uncertainty and reduce the risk of running out of stock.

PreBilt makes it easier to do cycle counting by guiding users through the process, highlighting any discrepancies as you go, and then getting the results back into SAP straight away.

That means you've got accurate inventory all year round, not just at the end of a long annual stock take.

Reducing complexity while maintaining control

There's a common misconception that making inventory processes simpler means losing control, the opposite is often true. Good inventory control can cut costs by up to 20%.

Best practice inventory management is all about:

• Cutting out unnecessary steps

• Reducing the number of decisions you need to make

• Standardising where you can

PreBilt helps reduce complexity by hiding the technical details of SAP from users and keeping full control in the background, keeping the SAP core clean and robust, giving users a simpler experience.

Managing inventory across multiple sites

Managing inventory across different warehouses or locations adds another layer of complexity. It also depends on strong supplier relationships and disciplined supply chain management.

Experts agree that best practice includes:

• Having consistent processes across all your sites

• Using standardised data and labelling

• Sharing rules but giving local sites some flexibility

Because PreBilt is flexible and configurable rather than being hard coded it can support consistent inventory management practices while still being able to accommodate site specific differences when needed.

Ensuring data quality through process design

Data quality is an outcome, not just something you do.

Inventory data quality doesn't improve because someone cleans it up in a spreadsheet afterwards, it improves because processes prevent bad data from being created in the first place.

Clean data is also really important for accurate demand forecasting and prediction.

Experts in inventory management agree that best practice focuses on:

• Validating things at the source

• Giving clear feedback to users

• Reducing the number of opportunities for error

PreBilt plays a key role here too. Every scan, movement and confirmation is checked before it hits SAP, keeping data clean without adding any extra administrative overhead.
