Thanks for your reply. We are building this marketplace to sell service. My main issue is not creating or handling services or non-shippable products. What I'm exactly looking for is that if customer added multiple products (services), then for each product an order be created. My problem will be solved by such solution. Is it possible by any module or tiny code changes?
As I had some searches, there were other people with the same issue (splitting an order) but it seems no solution is suggested. I hope I can find an answer here
Thanks again
