I sell custom-printed stickers and I want to be able to create quotes for customer orders. However, it would not be feasible for me to list every possible combination of elements as its own product since there are so many custom parts that go into each order. For example, pricing changes depending on size, color, number of stickers ordered, bulk discount etc. There is no stock item, each order is custom and will cost something different. How can I quote for this? The only way I know how currently is to create products, but with this level of product customization that won’t work.
