iOS: Got a wallet or drawer full of receipts you need to track? ExpenseMagic is a service that lets you photograph them on your iPhone and then has the data from them typed into a monthly expense report for you.
The service doesn't use optical character recognition, instead having the data entered by dedicated staff. ExpenseMagic has been customised for Australian customers, so GST and ABN details are automatically added. The data can be automatically pushed to Dropbox or Evernote, or added to your accounting system.
The ExpenseMagic app itself is free, but you pay for processing. A batch of 20 uploads is $5.49, a month of unlimited processing is $12.99, and 90 days is $21.99. If you're drowning in receipts, that could well be a sensible investment.
