How do I limit the quantities for the product that can be added to the quote?

Once the quote is created, you may either decide on the quantity for the product or let the end client decide the quantity. You can still maintain an upper hand even while allowing the end client to decide on the quantity by setting limitations. 

You may do so by following the below steps. After the document is created and the product is added, please select the Kebab menu next to the Section header.
