One common thread that all successful startup laser engraving businesses have is that they start off with a narrow focus regarding all aspects of the business. Choosing which markets to start with can be daunting. Pick one or two markets to start with and create a successful business wrapped around those markets. When it comes to materials, pick a few to begin with and slowly add more as the business grows.
One failure many startup laser engraving shops make is trying to take in all types of engraving jobs and all types of materials. It is ok to say no to customers when you are just starting out. Take your time, be successful, and grow slowly in all aspects and you will build a strong and loyal customer base that appreciates your quality and service.
