The best feature of this software would be its ability to create different types of quote templates depending upon what you need, like price only or also including quantity etc., which can then easily be edited by users once it has been created! Also great about Kineken is how easy they make creating your own pricing structure (for example if I want my clients to pay per mile instead of upfront) very simple with no coding required in most cases.
It's important as an e-commerce site owner we have control over our prices - not just rely on Google Shopping feeds being able to show us correct amounts at lower rates than competitors' products but are unable to change those values ourselves until after purchase.
