Each concern has its general manager, responsible directly to head-quarters, which handles internal bookeeping, taxes, finance, and law. But the latter usually only intervenes in the early stage; firms are on their own, with only monthly reviews.
而掌管內部帳目、稅務、財務、法律工程發展等事的總部，通常只在加入新工業或設廠之初才參與建立制度，公司一旦正式運作就「放牛吃草」，此後只進行按月考核。
