The developer is obliged to undertake continuous development of its programme: to make necessary changes in a timely manner, to find and repair errors, watch for updates version of the jQuery library, changes in PHP, HTML 5. Now web-programming and Internet is growing much faster than we think with You. The developer of the program need to constantly evolve and not to stand still. Only then this program will be always in demand and number of sales it will grow every year. Thank you.
