When I used to sell KM gear, clients would always ask me for ideas to boost their business. They would ask if they should get into garment printing, blueprints, wide format, etc. I would say that all of those would be good if you already have some demand to justify the costs of new equipment, but really, you just need to advertise more. Many print shops invest very little time, effort, and money into marketing themselves. I'd often hear that they advertised a lot in their early days, but then business was good, so they didn't really do it much anymore. Here are some ideas I shared before to boost your business.
