Eniven,Your new favorite word is "comparable." The best way to find out information about the industry is to look at comparables. Find a competitor who has recently gone public. Read and use their market analysis numbers. They must disclose pretty much everything in order to have an IPO. Most of what you need will be there. Best part - it`s free.Good luck.
I am not a financial advisor but have read up on this topic. Typically you split expenses because you are 50:50 profit partners. You can write into an operating agreement one party is liable for all expenses. This party will then be able to use those expenses in their tax return as deductions.
Brian,Terms on an invoice are what you set. A typical range is from 1%-5% (although 5% is a very large discount for only 20 days advance).Factorers look at who the purchase order is from (because that is what they are buying). A P.O. from Dell will have a lower rate than one from a small company because the likelyhood of Dell defaulting is low. I wish I could give you more of a range but it is a very negotiable deal. Good luck
