A Small Dropshipping Store That Suddenly Got More Attention Than Expected

Last week I helped a friend set up a tiny dropshipping store just to test a product idea. The plan was simple: a few listings, a basic supplier, nothing serious. Then a short video unexpectedly went viral, and the store received more orders in one evening than it had in the entire month. That sudden jump made us realize we never discussed the legal side at all. Now we are trying to understand how people decide what structure to use once a hobby project starts turning into something real. What helped you figure out the right moment to formalize your store?
