IP stands for Intellectual Property. When you deal with anything creative, you have to think about copyright and the intellectual property on that work and that includes the creation of software code.

This gets back to the question of buy vs. build. If there is an existing solution that can suit your needs just fine, then it makes sense to buy, but the software developer owns the code and you are basically licensing the software from there. However, if you need a specialized solution that is customized to your needs and decide to go the custom development route, then the question of who owns the code is an important one.
