A common merchant question
How should several variants use one limited pool of stock?
Practical answer
Choose one product that represents what you physically count. Avoid giving every selling option the full quantity, because that can make more stock appear available than you own.
How Kaijuu helps
Kaijuu lets you connect related products to one stock source. Stock updates remain a separate control that you choose to enable.
Separate presentation from stock
The storefront may need many choices while the stockroom holds one base item. Keep one physical quantity and treat each choice as a selling presentation of it.
Avoid duplicate independent counts
Giving every variant the full base quantity can multiply apparent availability. Use a shared relationship and confirm that one sale reduces the common pool.
Business example
Three framed-print listings use one boxed print
Oak Frame, Black Frame and Gift Wrap are selling choices for the same boxed print, with nine physical prints available.
| Listing | Ordered | Shared prints remaining |
|---|---|---|
| Oak Frame | 2 | 7 |
| Black Frame | 1 | 6 |
| Gift Wrap | 2 | 4 |
- Choose the boxed print as the stock source
- Connect each listing
- Review the common stock after five sales
