Our principles are that re-use of materials should benefit all parties and ultimately lower costs and decrease risks on projects. As such, offering value for money to buyers is critical. Having said that, being a marketplace, The Code Market doesn't seek to dictate prices (thats the job of the buyers within the market!).
Our general suggestion is that materials should be sold at 30% of the cost that a normal customer would incur, should they have done the work themselves. Let's work this through using an example of Ted, a Developer who developed some complex legislative reporting for the Financial Services sector.
If the customer had completed the reporting, it would typically take a month to design, develop, test and document the reports. The cost of this might be $100 000 (including all the usual project phases). Assuming that Ted owns the IP (and Ted may be the customer who initially developed the materials!), we would suggest that Ted could look to market the materials at $30 000.
This way, Ted recoups his initial costs and makes a profit after selling the materials four times. Likewise, buyers save a substantial amount and will have a vested interest in buying Ted's materials.
