Hi,
The crux of the matter is this sentence:
I open three different browsers. 1 and 2 order 6 each leaving 4 remaining
The stock of the product will be modified based of different conditions:
- First, if the product is in a cart, the stock is not changed. The stock is only changed later in the ordering process.
- In the HikaShop configuration page, you have the setting "Update the product stock on confirmed status". If that setting is turned off, then the stock of the product will be modified once the cart is transformed into an order. This happens when the customer clicks on the "finish" button at the end of the checkout, before he is redirected to the payment gateway for the payment.
- If the "Update the product stock on confirmed status" setting is activated, then the stock of the product will be updated after the order's status changes from "created" to "confirmed". This normally happens after the payment gateway receives the payment from the customer and notifies the payment plugin which will in turn ask HikaShop to change the status of the order to "confirmed".
So I'm thinking that the way your HikaShop is configured, it hasn't yet taken into account the purchase of the 12 products and thus it still only displays the initial stock.
Now, on top of all this, if you want to have a cart reservation system where the customers are guarantied they can purchase the products in their cart during a specific period of time, we have this newly released plugin:
