Office management software for a plumbing contractor?

[thecompu-doctor]

Just wondering what you all have run into as far as a full scheduling, invoicing and management software goes for a trade contractor?

I've found wintac seems to cover most of my clients needs, but I'm looking for more options.

I've also found QXpress that integrates in with quickbooks, which is a big bonus for my client as they already use QB.
