Hello. I have been using Podio for quite a while, and have set up completely custom workspaces for lead management, sales teams, project management etc...
It is very likely that you will need to create custom Podio apps for your needs, as the apps in the app market are just general and will not include everything you need. I can do this and have created many custom apps in the past.
I will work with you until the end to make sure Podio is functioning in the way you need it to.
Thanks
