Key Takeaways

Inventory control safeguards cash flow and ensures products meet demand.

• Sets min/max thresholds. 

• Uses cycle counts to stay accurate. 

• Integrates with sales to adjust stock. 

• Cuts dead stock via smart planning. 

• Protects service levels.

Inventory control is a crucial aspect of effective business management, encompassing the processes and strategies used to track, manage, and optimize stock levels. It involves overseeing the entire lifecycle of inventory, from procurement to storage, sales, and replenishment.

At its core, inventory control aims to strike a balance between meeting customer demand and minimizing the costs associated with excess inventory. By implementing robust store inventory control practices, businesses can ensure they have the right amount of stock on hand, avoid stockouts or overstock situations, improve cash flow, reduce carrying costs, and enhance overall operational efficiency.

Effective inventory control relies on various methodologies and tools, including demand forecasting, just-in-time (JIT) inventory management, economic order quantity (EOQ) calculations, and the use of technology-driven solutions. These techniques enable businesses to optimize inventory levels, reduce wastage, improve order fulfilment, and ultimately enhance customer satisfaction.

With LEAFIO AI's advanced store inventory control solutions, businesses gain access to cutting-edge technology that streamlines the entire inventory management process. Our innovative algorithms and machine learning capabilities empower businesses to make data-driven decisions, identify patterns and trends, automate reorder points, and gain actionable insights for smarter inventory control.

Inventory control is the meticulous process of overseeing and regulating the quantity of products within a company's stock to prevent both shortages and overstocking. It employs various methodologies such as the Economic Order Quantity (EOQ) and reorder points to strike a balance between procurement costs and holding costs.

In tandem with store inventory control, inventory management encompasses a more comprehensive approach to handling a company's stock. It involves strategic planning and forecasting, optimizing efficiency from procurement through to sales, and a keen focus on enhancing supply chain efficiency and overall profitability.

Key elements of inventory management include implementing robust inventory control systems to facilitate streamlined monitoring and management. These systems often incorporate advanced inventory tracking mechanisms, allowing real-time visibility into stock levels, demand patterns, and order fulfillment processes.

Different types of inventory control are employed based on the nature of the business and its products. For instance, a periodic inventory system involves conducting intermittent physical counts of stock to update inventory records. In contrast, a perpetual inventory system maintains continuous real-time tracking through automated tools and technologies.

An integral component of inventory management is recognizing the role of supply chain dynamics. This involves coordinating and optimizing the flow of goods from suppliers to manufacturers and ultimately to end consumers. Effective inventory management contributes to a more resilient and responsive supply chain, reducing lead times and enhancing overall operational efficiency.

In summary, while store inventory control primarily deals with day-to-day stock management through techniques like EOQ and reorder points, inventory management takes a holistic perspective, incorporating strategic planning, forecasting, advanced inventory control systems, tracking mechanisms, various types of inventory control methods, periodic inventory systems, and a keen focus on optimizing the supply chain for sustained profitability.

The main functional aspects of the store inventory control system include the following:

• specification of goods, their ID numbers and types of inventory control;
• keeping information on goods' serial numbers;
• barcodes implementation and control;
• ABC goods prioritizing;
• replenishment process;
• managing inventory lists;
• real-life/real-time warehouse reports;
• real-time goods location tracking;
• inventory storage oversight;
• accounting and tax operations associated with warehouse management;
• synchronizing warehouse stock with sales.

If a business does not control its stock, this can result in backorder or overstock, both of which are risky for financial performance and customer loyalty. Overstock is an excess of unsold goods which freezes operating capital and eventually becomes ‘dead’ stock that should be written off or liquidated. Backorder, in turn, leads to customer dissatisfaction, because a seller can’t supply them with the items they want in time. If a store inventory control system is implemented correctly, a business takes full oversight over its stock management.

By optimizing inventory control processes, businesses can also streamline supply chain processes, reducing logistics, storage and transportation costs.

So, the primary functions of store inventory control systems are clear, they help retailers to effectively spend their money on warehouse replenishment and restocking and to increase cash flow by rationally controlling the warehouse internally. Let’s talk about the main methods these systems use:

This formula calculates the amount of stock you need using the following indicators:

• Q - economic order quantity (units);
• S - ordering cost per purchase;
• D - demand in units;
• H - carrying cost per unit.

Read more about this formula here.

While the Economic order quantity formula points to the cost-effective amount of stock needed, Reorder time formula calculates the right time to order the goods. Here is a formula:

You need three indicators - a lead time, demand and safety stock.

It is the number of days needed for the stock order to be delivered to your warehouse after you have put in an order to your supplier. For businesses dealing with Chinese markets and shipping their stock from China, this indicator is crucial. When we are talking about routine regular orders, imagine how important it becomes during any logistics breakdowns, strikes, demand surges or seasonal deliveries.

To calculate the lead time demand, multiply two numbers: lead time for a particular item and average daily consumption of this item

It is a cushion, a buffer of goods available in your warehouse. To perform a safety stock calculation, multiply an item's highest (maximum) daily consumption and the highest lead time for this item (in days). Then multiply an item's average daily consumption and lead time (in days). Finally, subtract the latter from the first number. Voila, this difference is your safety stock number in items/units.

Importantly, efficient stock control needs a combination of these two methods, of both EOQ and Reorder Time.

One of the benefits of store inventory control systems is that they perform these calculations automatically and all you have to do is to turn on automated notifications – the system will automatically update you on reorder time and quantity!

Proper KPIs are fundamental to efficient inventory management, as these indicators drive future performance and profit. Most KPIs are coupled with Inventories as a primary asset of the retail business and with Sales as the ultimate result in retail. 

It is also worth understanding that many KPIs «dilute» everyone's contribution, and too few do not give the whole picture. So it is worth determining both the quality and quantity of KPIs in each business area you manage. 

Typical indicators are: 

1. INVENTORY COSTS. It gives a general idea about the company's investment in inventory at the moment and over time. In addition to tracking this indicator in the moment and dynamics, the assessment of the inventory structure demonstrates how much the company is worth in terms of insurance stock, inventory, surplus, and the actual stock for sales. 

Below are examples of the inventory structure of two grocery retailers (a gray area - insurance and on-shelf inventory, a green area - sales inventory, and a purple area - excess inventory):

2. SALES. Sales in purchasing prices (cost of sales) and selling prices. In essence, everyone in the retail company works for sales. Regarding category management, sales are analyzed by category in terms of outlets, suppliers, and other analytics. 

3. OVERSTOCKS. Shows the % and value of inventories that have been formed as a result of increased orders or a significant drop in consumer demand. In addition to the surplus itself, it is also worth assessing how long this surplus has been in the store or the warehouse.

4. LOST SALES. Show the % and value of potential statistical sales that did not occur due to out-of-stocks. It isn't easy to get an accurate % of missed sales due to the specifics of the indicator itself. But this does not mean that when analyzing the effectiveness of inventory management, we should abandon taking this indicator into account at all.

LEAFIO Inventory Optimization system has a special report on the statistics and causes of missed sales, which shows the changes in the dynamics of the indicator as a separate category of products and groups.

5. SERVICE LEVEL. It's a % of the availability of goods from the assortment matrix on the store shelves. It is similar to missed sales but measured in units rather than money.

6. INVENTORY TURNOVER. The ratio of inventories to sales shows how many days of sales the current balance will be enough.

To summarize, the KPIs above hold the potential to drive retail profits up and give clarity on operational performance at a time when circumstances change constantly.

Each business is unique, with its individual needs, KPIs, targets and strategies. Inventory control techniques and methods vary, but all of them are acceptable. The use of each method depends on your business size, model, policies and financial objectives.

You can use different store inventory control methods in your strategy, but switching between them too often can negatively impact financial reporting, accounting, and analytics.

Here is the very guide which takes you to the basics of implementing an inventory control system in your company. So, to get started:

In terms of inventory, the turnover metric is one of the most common, critical and useful indicators that shows the number of times inventory is being sold per year/quarter/etc. To set ideal inventory turnover goals, you have to take into account the benchmarks across your industry or sector and calculate profit margins for the whole inventory and each SKU in particular.

There are several other metrics to consider and monitor, such as inventory carrying cost, sales of inventory per day, the ratio of inventory to sales conversion, etc.

Efficient warehouse management, including goods movement, transfer and storage, is one of the most important elements of store inventory control. It’s all about common sense – if your warehouse is messy or the products are placed chaotically, you can hardly ensure a steady flow of sales, deliveries and inventory movement. Consider cycle counting as a way to perform stock counts and keep an eye on goods quantities.

If products are difficult to find and identify, you will need more manpower and more time for order fulfillment and logistics. If products are being searched and the “in and out” movement is controlled manually, the possibility of human error increases. To stay cost-effective and reduce the effects caused by human  error, create a user-friendly and easily categorized system for all your goods and products. The ABC method of inventory classification and analysis based on goods profitability and sales value is one of the most efficient options to consider.

Some owners of micro- or small businesses are running their control processes using an Excel spreadsheet with 2-3 functions and manually filling in all warehouse data by hand. Manual inventory control requires investment into human capital, as a person is responsible for fixing even the little movements of goods, keeping track of goods names, types, locations, numbers, etc.

On the contrary, automated inventory control systems can perform the following functions in seconds, saving time and costs. New technologies can automatically prevent overstock and backorders, track consumer demand and align inventory levels accordingly, predict the next warehouse order by analyzing sales and goods movement, manage warehouse and barcode systems, and even analyze future sales trends.

Are you struggling with retail inventory control problems and challenges? Do you find it difficult to maintain accurate inventory levels, manage stockouts and overstocking, and keep up with customer demand? 

Let's explore the problems and challenges associated with retail inventory control to better understand how to tackle them head-on:

Stockouts and Overstocking: Balancing inventory levels to avoid both stockouts and excess stock is a constant challenge.

Demand Forecasting: Inaccurate predictions of customer demand can lead to imbalances in stock levels.

Order Management: Inefficient order processes can result in delays and errors.

Technology Issues: Outdated or inadequate inventory management systems can hinder efficiency.

Supply Chain Disruptions: External factors like supplier issues or transportation problems can impact inventory control.

Inventory Obsolescence: Products becoming outdated can result in financial losses.

Effective inventory management is vital for businesses, and various techniques can be tailored to suit different needs:

1. Just-in-Time (JIT): Pioneered by Toyota, JIT minimizes inventory, reducing overheads by purchasing goods only when needed. However, precise timing is crucial to avoid stockouts.
2. Bulk Shipments: Buying and shipping goods in bulk is cost-effective for items with stable demand and long shelf lives. However, it requires upfront investment and careful consideration to prevent excess stock.
   
3. Dropshipping: By cutting out the middleman, dropshipping lowers overheads, but it sacrifices control over quality and delivery speed, with potential customer complaints directed to your business.
   
4. Consignment: This method allows experimenting with new product lines without upfront costs, placing the risk on the consignor who gets paid only after the goods are sold.
   
5. Cross-docking: Eliminating storage needs, cross-docking streamlines the supply chain, particularly useful for items with short shelf lives or same-day delivery promises.
   
6. Cycle Counting: A more convenient alternative to full stock takes, cycle counting involves regularly checking small amounts of inventory, ensuring accuracy and reducing the need for extensive audits.
   

Always remember to use a properly integrated inventory control system in your operations. Forecasting demand, keeping records of warehouse data and replenishing it on time is tiresome work that requires precise planning. An integrated stock management system is designed to help you. It will not only keep your cash flow steady, your stock managed, your barcode scanner system efficient and customers happy, but also maintain relationships with suppliers and synchronize all warehouse processes.
