I have zero experience with ecommerce but the concept of dropshipping makes sense to me as a starting point since there's no inventory risk. Not sure where to begin though. From what I've been reading, the steps seem to be: pick a niche, set up a store, find reliable suppliers, import products, and then market. The part that seems most complicated is the middle stuff, keeping pricing updated when supplier costs change, making sure out-of-stock products don't stay live on your site, and processing orders without errors. For anyone who has done this, what do you wish you knew before you started and what's the most common mistake beginners make in the first month? Also, are tools worth it for helping with the middle-ground stuff?
