QuickBooks & Xero et al were waaay more than I needed or wanted to pay for.
I ended up using the free tier of Toggl, doing a CSV export and generating a butt-ugly invoice from Excel.
If this tool were available, I'd have used it.
Invoicing in Bonsai is also free and pretty nice, especially if using other parts of their service.
I'm also currently exploring the invoice integration in Wave.
Both of these are free.
Focus on the time tracking, reporting, etc.
For my own use case I would like to have one location to enter time then select a range, hit "invoice" and be able to send that to a client with a very simple credit card payment system.
I'm a Front End Web Developer at a startup offering a time tracking app with QuickBooks integration. QuickBooks is a premium feature, but we have a 30 day free trial so you can give it a spin.
Our focus is on construction companies, who love our offline support, but it works great for time keeping for anyone and everyone here dogfoods the app every day.
We recently had a big investment come in from CAT: http://www.caterpillar.com/en/company/innovation/caterpillar...

Welcome to the niche, I've only been here for a year and I've been amazed at just how deep and complex a time tracking application really is.
Also, I didn't find where to generate an invoice.
