I have an ongoing relationship with an ad agency who subcontracts me to develop Wordpress sites for their clients. The design is provided by the agency. These are individual one-off projects for a specific client. But lately, they’ve started re-using the themes for other clients’ sites by hiring a cheaper/junior developer to install the theme and change the colors and logos and maybe move a few elements around, but it’s essentially the same site. (I didn’t build them as re-usable themes, so they’re just editing the stylesheet and some of the template code.)
I’m not sure if I should have a problem with this or not. They hired me to do a job, I charged them for the time it took to do the job, and I got paid. End of story. They now own the product at that point and can do what they want with it, no?
But yet… it seems kinda sketchy, because they’re getting a LOT more value out of the product I created than what they were initially charged for.
What do you think? How do you handle this situation?
