[thelist] development time cost on new functionality

[Bob Meetin]

I frequently run into this problem/dilemma.

With the work I do I commonly have to do substantial research and development for a custom feature for client A. It might be a few hours, perhaps a day, whatever.  Client A is satisfied to pay the cost, is not concerned about re-use.

Then along comes client B who needs the same application, then perhaps another. Once this function has been developed, it requires minimal effort to package it and apply to the next situation.  What is appropriate, to charge client B for the installation/configuration time only, or to add some additional licensing, whatever you might call it, cost to the package?
