Ask HN: Integrated Billing and Expenses for Consultants

Hello fellow HN readers. I'm looking for an all in one solution that does the following things:

* Time tracking which can be billed to clients * Expense tracking (expenses can be billed back to clients) * Import expenses from receipt images (preferably via smartphone) * Import expenses via email (for things I buy online) * Sending invoices.

It seems to me that only way to get something like is to hobble together a bunch of services. I'm currently using Freshbooks for invoicing and time tracking. (Eon is nice for OSX). Handling expenses has turned out to be quite tricky. Have you guys been able to construct anything similar to this?
