Any service company uses materials in its operations. In the beauty business, we spend 10% to 25% of the revenue or even more on products and materials. Do you ever think that the inventory in stock is a substantial amount of money frozen in products stored in your warehouse? You can not use them to cover your business cost or just spend them.
While it is essential to have inventory on hand to support your business operations, having too much of it ties up cash and results in high costs, and low levels cause stockouts and lost sales. Obviously, we must find the sweet spot — the optimal balance between having enough inventory to meet demand and keeping inventory costs low.
This article will explore how you can uncover hidden savings in your inventory management and maximize your return on investment (ROI). This metric, which measures the profitability and efficiency of an investment or business initiative, is critical to assessing the success and viability of projects and making informed business decisions.
To illustrate this idea, let's look at a simple example. Imagine a beauty salon owner who spent $30,000 on inventory. Every week, an extra $5,000 is required to support operations. However, if the salon could operate efficiently with only $20,000 invested in initial stock, the difference of $10,000 would be cash in the bank account, with nothing else changing. That's the idea — you can generate cash by reducing your inventory investment without changing anything else.

Hidden savings is something that appears when your inventory strategy is weak. And the key to resolving this problem is moving from tactical, reactive decision-making to a proactive, data-driven approach focused on maximizing efficiency and minimizing costs. Even though it might be a tough job without special software, I will explain the whole process in a way that helps you to implement the new approach in your business.
In developing an effective inventory strategy, it is essential to begin with the collection of data. This includes compiling a list of products utilized and each product's daily or weekly usage. Estimation of this usage can be accomplished by calculating the number of products used per service multiplied by the average number of services provided per week. For instance, if a hair salon uses half an ounce of shampoo per wash and performs ten washes daily, this translates to daily usage of five ounces.
However, for a more accurate measurement, I advise keeping records of each time a product is depleted. This practice will provide valuable insights that inform better decision-making. Here at Suplery, we adopt this stock-keeping method to make informed predictions of future demand.
The next step involves determining the ideal time between orders and order quantity. This analysis takes into account various factors, including internal business standards, supplier quantity discounts, minimum free-shipping amount, order processing costs, and daily product needs. Typically, the most popular products are ordered every 2-4 weeks. At the start, you can just pick up any frequency that allows you to minimize shipment costs and get quantity discounts.
With usage and ordering information, we can calculate the required inventory level to sustain operations between orders. In addition, to cater for unexpected events like increased demand or delivery delays, a safety stock amount must also be included. Together required inventory level and safety stock amount will be the target inventory level which, expressed in value this quantity, will show minimum inventory investment. Finally, the difference between the current stock value and minimal investment represents the hidden savings — funds that hat you can safely take out.
In order to reach your desired inventory levels, it is imperative to adjust your product ordering accordingly. This involves reducing the quantities of overstocked products, thereby decreasing the invoice total and freeing up funds.
A tricky thing in this process is the timing of reordering. Although it may appear logical to place an order when inventory levels reach the safety stock amount, the lead time for delivery must be taken into account. As we expect the order to arrive precisely when the inventory reaches the safety stock level, placing orders early enough to ensure timely delivery and maintain the target inventory level is advisable.
The most important thing here is to make this new inventory strategy a permanent fixture. It is essential to incorporate regularly reviewing the target inventory level, order quantities, and frequency into your daily operations. The use of software like Suplery can greatly assist in optimizing inventory levels and ensuring that orders are placed on time.
Moreover, data-driven analysis and continuous readjusting of inventory levels will allow keeping investment on a minimal sufficient level. So, you can maximize your return on investment (ROI) and ensure that your business operates as efficiently as possible. Whether you are just starting or looking to streamline your existing operations, these steps will help you get the most out of your inventory investment.
In this part, I will use the abovementioned theory to illustrate how the concept works.
Assuming a salon offers only one service, it uses 3 pieces of Product A and 5 pieces of Product B per service. Each pack of products A and B contains 50 pieces sold at $100 and $200 respectively. The salon currently has 15 packs of each product in its warehouse. The salon serves 25 customers per week and orders products every two weeks.
Here's how to calculate the target inventory level and hidden savings:
Step 1: Weekly usage
The salon uses 75 pieces of Product A and 125 pieces of Product B per week.
Step 2: Between order time
The salon orders product every two weeks.
Step 3: Operating quantity
To secure 2 weeks' worth of operation, the salon needs 150 pieces of Product A and 250 pieces of Product B.
Step 4: Safety stock amount
To account for fluctuations in demand and potential delayed deliveries, the salon needs a safety stock of 190 pieces of Product A and 315 pieces of Product B, or 2.5 weeks of operation.
Step 5: Target inventory level
The target inventory level is the sum of the operating quantity and safety stock, or 340 pieces of Product A and 565 pieces of Product B.
Step 6: Inventory investment and hidden savings
Each piece of Product A and B costs $2 and $4 respectively. So, the minimum inventory investment is $2x340+$4x565=$2,940. Currently, the salon keeps 15 packages of each product with a total value of $4,500. This results in hidden savings of $1,560, which is over 30% of the inventory value. My experience shows that is a quite common result. If fact, a salon can save 20% to 50% of inventory investment or from 4% to 10% of the overall monthly turnover simply by using efficient inventory strategies.
