Stock by Attributes 5.0 Beta (for v1.5.0)

[DivaVocals]

You are right this mod isn't going to solve your problem because I don't think you need to use attributes at all let alone an add-on to manage stock by attributes..

Why are you using attributes for this product at all?? If you are selling a product where 1 unit = 1/4 meter, and I choose 8 units this would be 2 meters correct?? If I choose 2 units, this is a 1/2 meter. If I choose 4 units, then this is 1 meter. So what is the need for attributes here?? I think if you have clear product descriptions your customers will understand that 1 unit is equal to 1/4 meter.

This add-on looks extremely useful, but I'm not sure if it will address my needs. Hopefully those who have used it can help me before I go through the pain of installing it unnecessarily.
The issue I have is our store will be selling fabric. Each product can be sold in 3 different sizes (quarter metre, half metre or metre).
We purchased in 5 metre "bolts", which equates to 20 quarter metre pieces, so initial stock level shows as "20 Units". We need the stock to be adjusted accordingly, so if for example someone purchases 2 metres, stock is reduced by 8 units, half metre only reduces stock by 2 units, etc.
In a fresh v150 install, the attributes sort the pricing perfectly but stock is only adjusted by the total quantity regardless of attribute chosen.

Will this add-on help me? If not, will any others that anyone is aware of?
All suggestions greatly appreciated.
