I work for a small development/marketing firm which until recently has been a single-developer shop. We use teamwork to manage new/active projects.

My question is, how do small/medium-sized web teams manage all of their sites? We have clients with custom web applications, WordPress themes, plugins/tools, and full WordPress installs that we manage. How do you keep track of credentials, repositories, documentation, etc?

Our existing project management software feels like it is for actively-developed projects, not maintenance. I'm curious to hear anything about how other teams work. Appreciated!
