Stock control different options

-- HikaShop version -- : 4.4.3
-- Joomla version -- : 3.9.28

Hello,
I have a client that sells multiple items via his website. Currently, he does not sue the stock control settings as he has a slightly more complex setup.

Some products will never be 'in stock' as they are too expensive to have sitting on a shelf and rarely ordered, but if they are ordered then the product is sourced and sent to the customer, therefore these products need to be available on the website for potential orders (even though technically stock is zero).

Then there are other items, for example lengths of copper, that are in stock. However, it could be that 30cm is not in stock but can be created by cutting down larger lengths that are in stock.

So technically, my client needs three stock states:

1. In Stock and available to order

2. Not currently in stock, but can be made from others items in stock items if ordered.

3. Not in stock, but can be fulfilled if ordered.

Does anyone have any ideas how I can achieve this within HikaShop?

Thanks

Lee

Nicolas,
Thanks for the reply. We have purchased and installed the 'pre-order' plugin. As the site is so large with over 16,000 products, we exported the hikashop_product db table and updated the product_preorder column with the values required on the required products / variants. Then uploaded the updated file and replaced the table with the modified version. All seems to have 'worked' successfully.

However, there seems to be some issues.

1. There appears to be a languge missing, PREORDER_RESET_VALUE, does not have an entry in the language file.

2. Now we have updated the product_preorder column, these values are not being shown in the backend when viewing a product or variant, even though the value is present in the db table the backend of the site shows zero value. But opening the variant and then saving, making no changes, seems to update the preorder quantity value to that shown in the db table?

How can I get the admin backend to read this column correctly and load the preorder value in the db column and not display zero?

Thanks

The pre-order plugin mentioned has its place but does not fully satisfy the requirements of the original post.

I have 2 plugins which might be useful in such situations:
