Financial risks are as significant as technical and market risks for physical goods companies. Take a look at how companies like Amazon are run, and you will see that pricing, cost, and payment terms are very important.
Amazon is a retailer. Soylent is a manufacturer. It has plenty of capital to not have to worry about inventory turns. Manufacturers need to worry about making a good product and getting into customer hands first and foremost. Financial shenanigans are a distraction for a budding manufacturer.
Speaking as someone who has worked at a few electronic hardware OEMs (and been involved in production), I can tell you that inventory cost and risks are a significant concern.
