    Is there a setting limits on the quantity of sales?

    Is there a setting limits on the quantity of sales?
    In the form of the product already exists the possibility to select the desired number of the buyer. How is possible restrict the buyer to show him that he chooses the product more than remains in stock? Thus the system will limit the sale of the product, which remains a little, or no longer exists. https://yadi.sk/i/Fg9Lss2FiyJFy

    I'm afraid that we do not have a quantity of available products in any of the Payment Tools.

    We can achieve what you are looking for by using widgets and regular form fields instead, for both presenting your products, and calculating the total amount to be paid, and then only passing that calculated amount to the payment tool for processing.

    Now, this is slightly more involved to set up, but we can use the Inventory widget to hold the total amount of available items for each product. (manual: How to Add a Widget to your Form)

    So if you have 3 products, you will add the Inventory widget 3 times to your form. The inventory widget allows for adding the product image as well.

    Then, you will use a Form Calculation to calculate the total price, such as:

    (number of product 1 selected X price) + (number of product 2 selected X price)

    And finally, we forward this data to the payment tool for payments, by following this guide:

    You can check out a demo form of the this setup, here:

    Please let us know if you need further assistance in setting it up, and we will be happy to help.
