is there any way to create product that you can change name when you are sending invoice? We have some small products that we don't want to create as new products. We use it only when we are doing invoice.
Changing prices is no problem, you can set whatever special price you wnat.
But changing the name is no possible out of the box. You can implement a module to do this. But if you ask me, it is a bad idea to print other things on orders than on invoices. So better create the products.
