I do get why businesses are moving away from custom work. Some of the stuff that you may need to do custom work is; welder, pipe bender, metal cutter etc. These tools are very expensive but are still probably the cheapest bit. Then you have to consider; having a larger workshop for the extra room for the tools, ensuring that your staff are adequately trained, PPE and WHS. Then there is the maintenance of the tooling, for example, purchase of consumables (welder gas, blades etc). On top of that, the administration of the tooling; purchasing, taxation etc.
