This same logic applies to you if you were a medical software provider. If you don't know enough about who you want to supply to, then you don't know what you can do for them. That's why medical leads are so important. It's not just about doing business. It's about finding out if they have issues that need dealing with. This could issues with their equipment, EMR system, etc. You don't even need to mention the many laws countries have with regards to the quality of these tools. Whether one likes it or not, it will affect the quality of their healthcare (and to an extent, their standards of living)
