How to Charge A software

Very complicated. It is this sole reason I closed my consultancy business and resorted to full time employment.

One thing you should look into is feature comparison with your competitors and how much do the charge. This would be a good starting point and bench mark.

Your customers are going to review all comparable software and their respective price. Typically, you will be asked like "You don't have this and this feature and why are you charging this".
