Now, now...PhilC's apps can and most certainly are used by vendors.
Can you do the same thing without his apps? Yes.
Do his apps save time? Yes.

Listen, if you know how to strip a CR2, transfer morphs, edit channels, model 3d, perform correct grouping of an obj file or are able to strip away all poly instances of a morph to allow you to sell to the public without infringing on copyright's...then there is no need for this post (or possibly his applications).

Making conforming clothing and/or characters for Poser is not an easy overnight learning process. There is a big learning curve. Sure you can do it but be prepared for some battle. His apps are designed for all levels of users...from newbs to vendors.

Before anyone buys any application they need to know ahead of time where and what their own personal shortcomings are...then target those areas and go hunting (for apps).

Comitted to excellence through art.
