If the towns villages don't produce what the workshop needs, it won't make anything, thus won't make money. How much the villages produce (hearth) effects how much you produce. How much your product sells also matters. Also: workshops make money in intervals, as they need time to create their product.
workshops not making money. I currently have a wood workshop in Senon A brewery in sargot The iron shop in maraunmath (spelling) None have generated any capital..luckily I can Smith, but trying to establish some positive income. The main thing is looking at the villages connected to the town.
