Multiple products, different units, one inventory

Question

The scenario is as follows:

Product A, SKU 1000, sold as 1 roll of 1000 meters of cable, price 800 euro Product B, SKU 1000, sold per meter of cable, price 1 euro

Those products should share the same inventory, if one piece of product A is sold, the available quantity of both products should be reduced automatically (product A by 1, product B by 1000). If 500 pieces of product B are sold, the available quantity of both products should be reduced automatically (product A by 1, product B by 500).

So its like this: multiple products, same SKU, different units, same inventory.

I am working with Magmi to import products into Magento so I think using a 3rd party plugin is not an option here. Whats the best solution in this case? I have done quite some research but haven't found how to tackle this issue.

Thanks in advance,

Hope to hear from you

Answer 1

Here are my 2 cents. Since A & B have the same SKU and should share the same inventory, why not make it a single product?
This way the stock is reduced correctly when you buy X meters.
If the price for product A is not 1000 * price of B then you can easily manage this with tire prices.
Create a tire price where customer group is ALL GROUPS and Qty is 1000 and set the appropriate price.
The prices should be per meter.
