Hi there, thanks for looking ...
What we are looking for is an upgrade to OS commerce that will enable the following.
1) As well as the standard Stock amount we want all products to have a second 'real stock' amount, this will be entered by the users.
2) On the order listing screen it will show you how many products that customer has ordered versus how many of those products hold a positive number in the 'real stock' field.
3) If we wish to ship an order that only contains half of the products in 'real stock' then it will display on the invoice that the other products are still awaiting delivery from our suppliers.
4) This is ideal, but not necessary
We wish to only charge customers when their order ships, so a feature to re-process the checkout when the order goes out would be great. But not imperative.
