Currently I track the following in one Google Spreadsheet:
- My personal budget and expenses
- Hours worked/billed for freelance work
- Invoices sent/received
It works, but the interface has its limits. Any other tools I found so far either manage personal finance or professional time-tracking and invoicing. But none combine the two.
http://www.duetapp.com comes very close, even includes project-management nicely, but misses personal finance.
Do you know of any such apps or tools?
