Qteedy

With Qteedy you can allow your customers to create a quote in your Shopify store instead of making an order. Quotes can be created on cart page or product page. You can adjust price for every particular customer and then turn a quote into an order automatically. Qteedy can create a Shopify order in your store after you sent a quote. But it will not if you don't need to! You could change Quote look and feel to match your store's design.
