If you are a small company, self-employed, lawyer, consultant or similar, and you receive most of your money from time, you can use TimeReporter.
The basic idea is that you can manage most of your affairs without using a computer, just your iPhone. But at the same time, if you want, you can download your data to a computer and import it into another application.
If you have someone helping you with your economy and administration, you can still send your own invoices, just send a copy to your administrator when you send the invoice to your customer.
