Hi,
1. Cost based - you actually check what are the costs and apply standard industry / target markup
2. Value based pricing is based on the customer willingness to pay and can be done in 2 ways:
3. Competitor based pricing - basically it's benchmarking against competitors. Make sure you take into account the segment (i.e. in premium higher price may be the proxy for quality)
Don't forget about the pricing strategy - here you define how you will price the product taking into account 1,2,3 and your company strategy. Maybe you decide to have a zero margin if you can crossell other services. Or maybe you would like to subsidize to win the competition. Also, think of price differentiation and having different pricing tiers (e.g. basic, premium or even freemium) and how it helps to drive price perception and fulfill strategic goals
Good luck!
