Hello,
HikaShop is an e-commerce system but with some configuration, you can achieve something close to what you want to do.
You can see to create "quote" orders with a special order status (for example, for "free" orders).
Then, once you have edit the quote to fill the prices etc, you can change the order status to make it available to final payment :
