Applications :: Finding Best Business Software?

I've been doing a lot of research and feel like I'm smoking crack for not being able to find what I want. I recently started a small client-service based business that has assets. What I'd like to do is find one application that does all of the following:

- Allow me to track time by project/client/task, etc. with a built-in timer that also allows bulk input of time
- Turn tracked time into invoices easily
- Track my expenses and mileage
- Track my assets
- Integrate with my bank accounts for reconciliation of payments, transactions, etc.
- Maintain all of the financials of my company (things like depreciation of assets, taxes owed, financial reports, etc.)
- Light customer management
- Export ability to excel, .pdf and email directly from the app
- Possibility of future integration with online credit card payments
