| Ingredients form the lifeblood of every food-related venture, regardless of whether it's a street food truck or a bustling restaurant. The finished product, and everything that goes into creating it, from raw materials like flour and eggs, constitute the inventory. This inventory is crucial, ensuring businesses can satiate customer demands and optimize profits.
| | Imagine buying 500 hamburger buns on Monday and only selling 100 by Friday. The rest go stale and straight into the trash. That's money you just threw away. |

| == Poor Inventory Management Risks == | | == What Is Inventory? == |
| Poor inventory management can lead to risks that can significantly impact a food business's financial health and operational efficiency. Here are some of the risks associated with poor inventory management:
| |
|
| |
|
| # '''Cash crunch''': Too much capital invested in inventory reduces the money available for other critical business operations such as expansion, marketing, or even meeting day-to-day expenses. This can lead to a cash crunch, making it difficult for the business to respond to unexpected expenses or opportunities. The business might be forced to borrow more money to finance its operations, increasing debt and interest expenses.
| | '''Inventory''' is the stuff your business has on hand that it plans to sell or use. For a food truck, that's your ingredients: buns, lettuce, meat, sauces, drinks. For a clothing store, it's the shirts on the racks. For a tech company, it's the laptops in the warehouse. |
| # '''Inventory bloat''': This refers to a situation where a business has more inventory than it can sell in a reasonable time. This can occur due to over-purchasing, poor sales forecasting, or sudden changes in market demand. While having a large inventory might seem like a good idea, as it ensures that the business can meet any sudden increase in demand, it comes with its own problems.
| |
| # '''Spoilage''': If items aren't sold before their expiry date, they have to be discarded, leading to direct financial losses. This is especially relevant for food businesses, where many items have a short shelf life.
| |
| # '''Damage:''' The more items a business has in its inventory, the higher the chances of items getting damaged due to accidents, poor handling, or even natural disasters. Damaged items can't be sold, leading to financial losses.
| |
| # '''Unnoticed shifts in demand''': When a business has a large inventory, it might continue selling items that are no longer popular, while missing out on new trends that could bring in more revenue.
| |
| # '''Price fluctuation''': The cost of items can change due to factors like changes in supply, changes in demand, or even geopolitical events. If a business has a large inventory of an item whose price drops significantly, it might have to sell the item at a loss.
| |
| # '''Inventory write-down''': In the case of a business sale, only a portion of the inventory's value is typically going to be recovered.

| Inventory Performance Monitoring
| | == Why Waste Hurts == |
|
| |
|
| Most businesses measure their inventory performance using the '''Inventory Turnover Ratio (ITR). ITR''' gauges the frequency of inventory buying and selling during a certain period. It is considered a liquidity indicator<sup>{{#info-tooltip: <big>Liquidity indicators are financial ratios that measure a company’s ability to pay off its short-term debt obligations. They show a company’s cash levels and the ability to convert other assets into cash to pay for liabilities and other short-term obligations.</big>.}}</sup> as cash flow improves when inventory 'turns over' rapidly instead of stagnating unsold.
| | Every item sitting in your storage costs you money. You paid for it, and until you sell it (or use it to make something you sell), that money is stuck. And if the item goes bad before you can use it? That money is gone forever. |

| | '''Waste''' is one of the biggest profit killers for food businesses. Throw away 20% of your ingredients and you just wiped out a huge chunk of your profit. This is why tracking what you buy and what you use is so important. |
|
| |
|
| == Simulation == | | == The Real Term: Just-In-Time (JIT) == |
| Most businesses use a management system to maintain an appropriate inventory level and use the ''Inventory Turnover Ratio'' to measure inventory performance.
| |
|
| |
|
| === Inventory Turnover Ratio ===
| | '''Just-In-Time''' (or JIT) is an inventory strategy where you order supplies right before you need them, rather than keeping a big stockpile. The goal is to minimize waste while never running out. |
| Inventory Turnover Ratio (ITR) measures the number of times inventory is bought and sold over a certain period. It is a liquidity indicator because cash flow significantly improves when inventory is 'turning over' (moving in and out) frequently instead of sitting unsold in storage.
| |
|
| |
|
| Although the appropriate turnover rate depends on the size of a business, a low turnover ratio generally indicates lower sales or too much inventory in storage. A higher ratio indicates higher sales and requires efficient inventory management to meet demand.
| | JIT was popularized by Toyota in their car factories. Instead of storing thousands of parts in a warehouse, they had parts delivered right when the assembly line needed them. Less storage space. Less waste. Less money tied up in stuff sitting on shelves. |
|
| |
|
| Because the shelf life of food and its related stock is often short, food businesses aim for higher inventory turnover. Inventory turnover can be calculated using either the '''cost of goods sold''' (COGS) method or the total sales method. The COGS method is preferred because it excludes the retail markup included in the sales method, which can falsely inflate results.
| | For a food truck, JIT means ordering ingredients more frequently in smaller amounts rather than buying in bulk and hoping you use it all. |
|
| |
|
| ==== Inventory Turnover COGS ==== | | == Overstock vs Stockout == |
| This method uses the Cost of Goods Sold (found on the income statement) and Average Inventory to determine inventory turnover. The formula is:
| |
| Inventory Turnover = COGS / Average inventory
| |
|
| |
|
| Average inventory = (Beginning inventory + Ending inventory)/2
| | The two biggest inventory mistakes: |
|
| |
|
| == Management Systems ==
| | * '''Overstock''': You ordered too much. Food spoils, money is wasted, and your storage is full of stuff you can't sell fast enough. |
| Developing an inventory management system for a food stand requires consideration of storage space constraints and the sales forecast.
| | * '''Stockout''': You ordered too little. Customers want to buy, but you have nothing to sell. Every stockout is a missed sale and a disappointed customer who might not come back. |
|
| |
|
| === Storage Space ===
| | The goal is to land in the middle. Enough to meet demand, not so much that you're throwing things away. |
| In the simulation, all inventory is stored on the food stand. Storage space is limited, and the goal is to balance maximizing cash flow and storage space.
| |
|
| |
|
| ==== Bulk Purchasing ==== | | == How to Figure Out How Much to Order == |
| Maximizing storage space may sometimes mean bulk-purchasing some ingredients to reap cost savings. Before making a bulk purchase, consider the discounts on offer from vendors closely to be sure:
| |
|
| |
|
| a. The cost savings is worth tying up the cash.
| | The best approach is to track your data: |
|
| |
|
| b. There is sufficient space to store the items.
| | * '''Look at past sales''': How much did you sell last week? Last month? That's your baseline. |
| | * '''Watch for patterns''': Do you sell more on weekends? During lunch? Near payday? Adjust orders based on these trends. |
| | * '''Add a safety buffer''': Keep a small extra amount for unexpected demand, but don't go overboard. |
| | * '''Review and adjust''': Check your waste at the end of each day. If you're consistently throwing food away, order less. If you're selling out early, order more. |
|
| |
|
| c. There are no potential expiration issues.
| | == How It Works in Business Heroes == |
|
| |
|
| ==== Minimizing Waste ====
| | Inventory management is a constant balancing act in the game: |
| Properly managed inventory ensures minimal waste. Waste can be categorized as any ingredient or drink thrown away due to overstocking, spoilage, or expiration. In the simulation, wastage occurs when ingredients or drinks get thrown away because you ordered more than you could store. Any purchased item that exceeds the food stand's storage limit turns to a loss called Wasted Overstock. It is easy to overstock in a bid to reap some cost savings on bulk purchasing an ingredient.
| |
|
| |
|
| ==== Expiry Management ====
| | * '''Storage capacity''' is limited. Each business unit type has a fixed amount of storage space. Bigger trucks hold more, but even the biggest truck has limits. |
| '''Expiration''' issues are a serious consideration when making bulk purchases. Although this might not be in the simulation yet, expiry management is an essential part of food inventory management and deserves mention. Food safety mandates that safe and fresh ingredients are used in all consumable products. You need to use your stock well before its expiry date and ensure that no product that includes expired ingredients is sold to customers. One way to ensure effective expiry management is using the "First Expired, First Out" (FEFO) method. FEFO means that the ingredients with the earliest expiration date are used first. | | * '''Cold storage''' is needed for perishable ingredients. Without upgrading to cold storage, you can't carry items like fresh meat or dairy. |
| | * '''Manual ordering''' gives you full control. You pick what to buy, how much, and when. This works great if you're paying attention. |
| | * '''Auto-replenishment''' lets you set automatic reorder points. It saves time but might over-order or under-order if your sales patterns change. |
| | * '''Spoilage happens'''. If ingredients sit too long, they go to waste. Track what you're using and cut back on items that spoil before you use them. |
|
| |
|
| But FEFO will be unable to help if an item or ingredient with low demand is bulk-purchased. It is safer and more profitable to make bulk purchases of high-demand items and ingredients to avoid the loss of having some stock expire while in storage.
| | The best players check their inventory regularly and adjust their orders based on actual sales. Don't guess. Use your data. |
|
| |
|
| To do this, however, a knowledge of how the food stand consumes each ingredient daily is required. And this knowledge is at the heart of sales forecasting.
| | == Real-World Example == |
|
| |
|
| === Sales Forecasting ===
| | Walmart is one of the best inventory managers in the world. They use real-time data from every store to know exactly what's selling and what's sitting on shelves. When a hurricane is coming, they already know to ship extra bottled water and Pop-Tarts (seriously, their data shows those are the top sellers before storms). |
| Intelligent sales forecasting improves the inventory management process. Accurately estimating the food stand's future sales under varying conditions will help to avoid unnecessary inventory purchases.
| |
|
| |
|
| There is no single way of accurately estimating sales for a food stand. Still, you can use some information in the simulation to generate a decent estimate. The quickest way is to track the number of burgers and drinks sold daily and use that as an estimate for future inventory needs. This method, while easy, does not account for the different factors that impact sales.
| | This data-driven approach to inventory is why Walmart can keep prices low while rarely running out of popular items. |
|
| |
|
| ==== Performance Logs ==== | | == Key Takeaway == |
| To significantly increase accuracy, the following data can be logged:
| |
|
| |
|
| * Daily or weekly number of burgers and drinks sold per stand.
| | Good inventory management means having just enough of the right stuff at the right time. Track your sales, watch for waste, and adjust constantly. |
| * Amount of ingredients used (per recipe).
| |
| * Average population size during the period (including any event that caused an increase or decrease).
| |
| * Weather and temperature during the period.
| |
| * Any news events or occurrences during the period.
| |
|
| |
|
| These logs can serve as historical performance data to guide daily or weekly sales estimates and hence, stock purchasing decisions.
| | == Watch and Learn == |
|
| |
|
| === Using a PAR System === | | {{#widget:YouTube|id=jxH1oEGP-iE}} |
| Stock requirement estimates can be narrowed further to the ingredient level by combining the information in your logs with a Par System. PAR stands for Periodic Automatic Replenishment. While the name sounds complex, it is a straightforward system. It indicates the amount of stock needed to service your food stand over a fixed period.
| |
| | |
| If you use 300 grams of burger patty in a particular recipe daily or weekly, that's your par for the period. You will maintain a par sheet where the amount of inventory left in storage is updated and compared with your par, and the difference is purchased accordingly.
| |
| | |
| For instance, if the food stand uses 72 cans of sauce per week, the amount of sauce entered in the par sheet is 72. The sheet is reviewed at the beginning and end of the week, alongside the number of cans left in storage. Then, orders for the following week are placed to ensure the minimum par level is met. Par levels change based on season, weather, and events. You can easily use the information in your logs to predict appropriate par levels under varying conditions.

What Is Inventory?
Inventory is the stuff your business has on hand that it plans to sell or use. For a food truck, that's your ingredients: buns, lettuce, meat, sauces, drinks. For a clothing store, it's the shirts on the racks. For a tech company, it's the laptops in the warehouse.
