I've been asked to possibly duplicate a website I have written for a small organization which has a few branches. It is each of the branches that would like the site. I would be writing a single customizable site and distribute a copy to each branch. Each branch has their own budget. I'm curious on if there is a common way to charge for this. Would I just charge each branch as if it was a single site sale, or sell as a package that the organization would distribute. It seems as if there were a licensing scheme it would be easy for them to get around it.
I have done such a project recently. I made a fixed price per license which was lower than the total development price for the project, buth the combined licences nicely add up. There was only one customer who initialy wanted the project, so developing costs were at my risk.
This kind of stepwise pricing can be worth it if developing a single site may be too expensive for one customer, but when you know or reasonably can assume that others will also buy it, is worth the effort. With my project, every customer including the first one knew about the price discount and that the project could be distributed to others. Your situation is different because you already did the development for one organization. You should carefully read the contract you have with them to see if you are allowed to resell the same site twice; it could well be so that the first organization owns rights which prohibit reselling.
