For one product I need to be able to plan stock per day of month.
For example in backend
I see a calendar with whole month where every day has it's own stock. I can set whatever stock I want on whatever day I want.
For example in frontend
A customer puts 500 units in his basket, he goes to checkout and when he comes to Delivery he will see a calendar for a 30 day period of time and every day show the amount of stock for that day (just as set/planned in backend)
He pays and will get his order delivered on the day he choosed.
Now, the stock for that day only, should be affected. So when the next customer tries to make an order on the same day the stock should have lowered so the new customer cannot overbuy the planned stock.
Summary
So for this product the stock should be set per day of month and selling should only affetct that particular day.
This does not need to work with advanced stock manager, but it has to have minimum quantity of product per order and a maximum quantity per order. It has to function with multistores. And this is a Prestashop module that's wanted.
