Hi, my client has a Grocery store and want to sell online with shopify. He sells product by weight. What he want is that when a customer place an order (EX: 2kg of carrots), the customers see an "expected" total price. Then my client will modify the order with the exact quantity and price, send the bill to the client, and when paid he send the products. That's because when building the order the carrots could be 2.1kg or 1.9kg (hard to be exact 2kg) and the total price will change. There is a way we can do that? Can the order placed online be as "draft", then change the weight and price with the right one and send the new invoice to the client for payment?
