Just a few general business questions: Sp, for a certain project, I have startup costs, I have monthly costs like rent and electricity, I have variables costs based on the materials I use to produce, but what do I call mid-development costs that I use to increase the cash flow? Like for instance, if during the second fiscal quarter of starting a company I run an add, and the add servers no other purpose than the increase the cash flow, what kind of expense is that called?

Another is: How exactly do you find out or estimate how many sales you get for just a random kind of product? What would I research? What information would I look for?
