If your profit margins are lower than expected despite strong sales, hidden costs in your ordering process may be to blame. These costs can significantly impact your profits by increasing overall business expenses and reducing the efficiency of your supply chain. This inefficiency can lead to more extensive and more costly problems over time.

This article will explain identifying, calculating, and managing these ordering costs. By addressing these hidden expenses, you can improve your profit margins and enhance the financial health of your business.

What Is an Ordering Cost?

Ordering costs refer to the expenses associated with placing and receiving orders from suppliers to replenish inventory. This includes administrative costs, order processing fees, delivery charges from suppliers (such as shipping, labor, packaging, and additional overhead expenses), and setup costs. Understanding ordering costs is crucial for assessing a company’s sales profitability and the efficiency of its order fulfillment process.

These costs significantly influence inventory management strategies. For instance, high ordering costs might lead a company to buy inventory in larger quantities but less frequently to reduce these expenses. This strategy, however, needs to be weighed against carrying costs, which are the expenses associated with storing and maintaining inventory.

It’s vital for businesses to accurately calculate both ordering and carrying costs to find their optimal order quantity. This is the amount that minimizes overall inventory management costs.

Ordering cost also plays a key role in determining the Economic Order Quantity (EOQ), which helps optimize inventory levels by balancing holding and ordering costs. For example, a business might face ordering costs like paperwork, transportation, and quality control checks when placing orders with suppliers to restock its supplies of raw materials or finished products.

Key Examples of Ordering Costs

Ordering costs are expenses incurred during the procurement of goods and services. Here are some common examples of ordering costs and their impacts on expenses:

• Shipping Costs: This includes fees for transporting goods from suppliers to your warehouse, such as carrier fees, expedited shipping charges, customs duties, and handling fees. These costs vary depending on the order volume, shipping distance, and delivery speed, directly affecting your cost of goods sold.
• Administrative Costs: These are expenses related to processing orders, including labor and resources for preparing purchase orders and communicating with suppliers. These costs are high if your business frequently places orders, especially as complexity and volume increase.
• Setup Costs are expenses related to preparing equipment or machinery for production, particularly for small or customized orders. These costs can be significant due to the time and resources required to adjust machinery or processes, impacting production efficiency and per-unit costs.
• Inspection Costs: These costs arise from inspecting goods to meet quality standards. They include labor and resources for verification processes. If discrepancies or defects are found, additional expenses such as returns or reordering can increase the ordering costs.

How Carrying Costs Are Related to Ordering Costs?

Carrying or holding costs encompass the total expenses associated with storing and maintaining inventory over time. These include warehousing expenses, insurance premiums, depreciation of goods, and the opportunity cost of capital tied up in unsold stock. Conversely, ordering costs are incurred each time an order is placed, covering administrative tasks, shipping, and inspection of received goods.

The relationship between carrying and ordering costs is pivotal in inventory management. Frequent, smaller orders can reduce carrying costs by minimizing the amount of inventory held, but this strategy increases ordering costs due to the higher number of orders processed. Alternatively, placing larger, less frequent orders can lower ordering costs but elevate carrying costs, as more inventory is stored for extended periods. Achieving an optimal balance between these costs is essential to minimize total inventory expenses and maintain efficient operations.

How to Calculate Ordering Costs?

To calculate ordering costs, follow these steps:

1. Identify Key Components of Ordering Costs

To calculate ordering costs, you must identify all the expenses involved in placing orders. These typically include administrative costs, which cover the expenses for processing purchase orders, such as labor and resources.

Shipping costs are also crucial, as they pertain to the fees for transporting goods from suppliers to your location. Additionally, inspection costs should be considered, which involve the expenses for inspecting and verifying the quality of the received goods.

2. Calculate the Total Ordering Cost

To calculate the total ordering cost, use the following formula:

Total Ordering Cost = (Number of Orders per Period) × (Cost per Order)

Here, the “Number of Orders per Period” refers to the total orders placed within a specific timeframe, such as monthly or annually. The “Cost per Order” is each order’s administrative, shipping, and inspection costs.

For example, consider a business that places 20 orders monthly, with costs per order broken down as follows: $50 for administrative, $100 for shipping, and $30 for inspection. This results in a total cost per order of $180 ($50 + $100 + $30 = $180). Applying the formula, the calculation would be: 20 orders per month × $180 per order = $3,600 per month. Therefore, the monthly ordering costs for the business would amount to $3,600.

The Importance of Managing Ordering Costs in Inventory Control

Ordering costs are not merely an entry in your financial statements—they are essential in managing your inventory and maintaining a profitable fulfillment operation.

Each order brings associated expenses for processing, shipping, and receiving inventory. These costs can accumulate rapidly with frequent orders. High ordering costs can reduce profit margins without careful management and pressure your cash flow and financial resources. Controlling these costs is vital for profitability, particularly in industries with narrow margins.

The economic order quantity is a useful metric for determining the right amount of inventory to order, helping balance the costs of ordering against the costs of holding inventory.

Understanding Economic Order Quantity

EOQ is a method businesses and organizations use to determine the optimal amount of inventory needed in stores. By calculating EOQ, companies can find effective strategies to decrease ordering and carrying costs. Operations and supply management professionals commonly utilize this metric to keep inventory purchases within budgetary constraints.

Additionally, businesses calculate EOQ to decide the frequency of inventory orders; ordering less frequently can help lower the costs of placing orders. When assessing EOQ, several important factors need to be considered:

• Carrying Costs: Carrying costs include expenses for warehouse space, utilities, insurance premiums, and depreciation of inventory value due to obsolescence or technological advancements. Opportunity cost also factors in, representing potential returns missed when capital is tied up in inventory.
• Ordering Costs: As mentioned, ordering costs are expenses incurred from placing and receiving inventory orders. These include administrative costs related to processing purchase orders, shipping and transportation fees, inspection costs to ensure inventory meets specifications, and setup costs, particularly in manufacturing setups.
• Annual Demand: Annual demand measures the total inventory needed annually to meet customer needs. It incorporates historical sales data to forecast future needs, adjusts for market trends and seasonal changes, and considers the product life cycle stage. Lead time is also critical, covering the period from order placement to inventory receipt.

How to Calculate Economic Order Quantity?

The EOQ formula assists companies in calculating the best order quantity to reduce overall inventory management costs, which cover the costs of ordering and storing inventory.

To figure out the EOQ and ordering cost for your business, you can follow these practical steps:

• Determine Annual Demand: Start by figuring out how many units of a product you sell or need over a year. You can find this information on your company’s income statement from the previous year. Look for the total number of products sold annually. This step can be repeated for each type of product your company deals with.
• Calculate the Cost Per Order: This step involves adding up all the costs of placing an order with your suppliers, such as procurement, administrative expenses, and processing fees. To get this number, divide the total amount spent on placing orders with suppliers last year by the number of orders. Remember, this cost might include delivery charges from suppliers, setup costs, and interest charges on credit purchases.
• Assess the Carrying Cost Per Unit: This cost is what it takes to store a single inventory unit. Add the capital cost (what your company invests in inventory), inventory service costs (like insurance, taxes, and maintenance), and inventory risk costs (which could cover things like theft or depreciation). Don’t forget to include storage costs such as rent and utilities. Sum all these costs and divide by the total number of units to find the carrying cost per unit.
• Apply the EOQ Formula: Now use the EOQ formula, which is EOQ = √[(2 x Demand x Order Cost) / Carrying Cost]. Fill in your specific values for demand, order cost, and carrying cost to calculate the EOQ. This figure represents the optimal number of units to keep your ordering costs as low as possible.

Example of Calculating Ordering Cost Using EOQ Formula for a Retail Business

Suppose you own a retail store that sells a popular electronic gadget. You want to manage your inventory efficiently to save money. Here’s what you know:

• Annual Demand (D): You sell 12,000 gadgets each year.
• Ordering Cost (S): Every time you place an order, it costs you $100 (including administrative costs, order processing etc.).
• Carrying Cost (H): It costs $5 to store one gadget for a year (including storage space, insurance, etc.).

Step 1: Identify the Variables –

D = 12,000 gadgets/year

S = $100 per order

H = $5 per gadget/year

Step 2: EOQ Formula –

EOQ= √[(2 x Demand x Order Cost) / Carrying Cost]

Where,

EOQ= √[(2 x 12,000 x 100) / 5]

Step 3: Calculate the Numerator and Denominator –

2 × 12,000 × 100 = 2,400,000

Where the Denominator:

Carrying Cost = 5

Step 4: Divide the Numerator by the Denominator –

2,400,000 / 5 = 480,000

Step 5: Take the Square Root:

EOQ = √480,000 ≈ 692.82

Since you can’t order a fraction of a gadget, round up to:

EOQ = 693 gadgets

Interpreting the Results

Based on the annual demand of 12,000 gadgets, you must place orders approximately 17 times yearly. This is calculated by dividing the annual demand by the order quantity (12,000 ÷ 693 ≈ 17.31). Ordering at this frequency helps balance ordering costs and carrying costs, ensuring efficient inventory management.

Several calculations are necessary to determine the total ordering cost.

• First, the number of orders per year is found by dividing the annual demand (12,000 gadgets) by the right order quantity (693 gadgets), resulting in approximately 17.31 orders per year.
• Next, the total annual ordering cost is calculated by multiplying the number of orders (17) by the ordering cost per order ($100), which equals $1,700 annually.

The average inventory level is then determined by dividing the order quantity (693 gadgets) by 2, yielding an average inventory of 346.5 gadgets. To find the total annual carrying cost, this average inventory is multiplied by the carrying cost per gadget ($5), resulting in $1,732.50 annually.

Finally, the total annual inventory cost is the total ordering cost ($1,700) and the total carrying cost ($1,732.50), equaling $3,432.50. So, by ordering 693 gadgets each time, the company places approximately 17 orders per year, incurs an annual ordering cost of $1,700, an annual carrying cost of $1,732.50, and a total inventory cost of $3,432.50.

Effective Strategies to Manage Ordering Costs and Optimize Inventory

Managing your ordering costs is essential for keeping your inventory expenses in check. Here are some practical strategies to help you save money and improve your business operations:

• Negotiate with Suppliers

Conversations with suppliers can open doors to benefits like bulk discounts, lower shipping fees, and better payment terms. Establishing strong relationships through regular and significant orders builds trust, which might lead to more favorable deals and ongoing cost reductions.

• Automate the Ordering Process

Automation tools such as enterprise resource planning (ERP) and inventory management software can help simplify purchase order creation, approval workflows, and inventory tracking processes. This cuts administrative costs, reduces errors, and improves data accuracy, offering valuable insights for further cost reductions.

• Improve Warehouse Layout and Space Utilization

Keeping your warehouse organized can decrease the time and effort needed to handle incoming orders, reducing administrative and inspection costs. Efficient use of space allows you to store more inventory without increasing carrying costs, helping you balance your ordering and holding expenses effectively.

• Consolidate Orders When Possible

Merging several smaller orders into one larger order can reduce the number of shipments and related costs, such as transportation and handling fees. For example, consider a bi-weekly or monthly schedule rather than placing weekly orders for materials if it suits your inventory needs. This strategy lowers shipment frequency and maximizes bulk purchase benefits, improving cost efficiency.

• Implement Just-In-Time (JIT) Inventory Management

Adopting a JIT system means that materials and products are ordered and received only as needed for production or sales. This approach lowers holding costs and minimizes the risk of having too much stock, leading to more effective inventory management.

• Utilize Data Analytics for Demand Forecasting

Data analytics to understand demand trends allows for more precise ordering, reducing surplus inventory and stockouts. Accurate forecasting helps maintain optimal inventory levels, keeping ordering costs under control.

• Establish Vendor-Managed Inventory (VMI) Agreements

With VMI, your suppliers take care of the inventory levels of their products in your warehouse. This arrangement can lead to more efficient stock turnover and lower ordering costs since suppliers are vested in optimizing inventory levels.

• Regularly Review and Adjust Order Quantities

Reviewing and tweaking your order quantities based on sales data and inventory turnover helps ensure that your ordering practices stay in tune with your current business needs, avoiding over or under-ordering.

Conclusion

Understanding and managing ordering costs is essential for maintaining profitability and operational efficiency. These costs, which include administrative expenses, shipping, and inspection, can significantly impact overall business performance if left unchecked. Balancing ordering costs with carrying costs is crucial to minimizing total inventory expenses.

Tools like the Economic Order Quantity (EOQ) formula provide valuable insights, helping businesses determine the right order quantity and frequency. By carefully calculating and addressing these costs, companies can enhance their inventory management strategies, improve profit margins, and ensure better financial health.
