Just look at the price per piece to decide which one to choose.
On the Supplies Ordering screen, the larger the bundle, the lower the price per unit. As a hypothetical example, if a pack of 100 is 130 won each, a pack of 200 is 115 won, and a pack of 500 is 100 won, since they are the same product, you will naturally go for the larger one.
All that is displayed on the screen is the price per unit. that is How many months is it?is not written.
Revealed after the box arrives
If a shelf receives 400 units and has 700 units in stock, there is no room for 300 units. The remaining boxes are stacked in the aisle next to the workbench, reducing the space you have to pass by.
The money you save stays on your receipt. However, the narrowed route is not recorded in any ledger. So you only find out after you buy it.
Two numbers complete the calculation.
| value to take out | where | example |
|---|---|---|
| In stock now | Amount remaining in warehouses and shelves | 200 |
| usage per month | Recent performance of ordering records | 100 |
It is more accurate to obtain both values from the order record rather than guessing them from memory. If the estimate is larger than the actual value, you will end up buying more than you need, and if it is smaller, it will quickly drop.
Let's look at how many months it will take and where to put it.
The calculation is two lines.
- 200 units in stock + 500 units on order = 700 units
- 700 units ÷ 100 units per month = 7 months supply
Overlay the storage capacity here. If the shelf receives 400 units, it is 700 − 400, which is 300 units exceeded. If you decide based on just how many months you have, you won't see these 300.
Reduce your order and it will end up on the shelf
If you order only 200 units, your inventory will be 400 units, which is 4 months' supply and is exactly the amount you can store. The price per unit will increase slightly, but the aisles will remain the same.
I’m not saying that buying in bulk is wrong. If it is within the storage capacity, purchasing in bulk is obviously advantageous. However, the expiration date and storage conditions vary for each item, so you should first check whether the item can be stored for a long time. For items with high seasonal demand, it is safer to use the average of the last few months rather than one month's worth.
Today I just write down two numbers
Before you press the order button, just write down your current inventory and monthly usage. The actual store was not photographed and the boxes were drawn as shapes.
