Our iPhone application acts as a mobile receipt scanner. It can also be
used to log cash receipts. But both of these operations tie directly
into the full online service. It’s also entirely free.
we do expense
reports that don’t suck. We do it by importing your expenses *and your receipts* straight from your credit card, submitting PDF expense reports by email, and reimbursing reports up to $10,000 entirely online (now with QuickBooks support).
It’s a hosted service available at expensify.com, also integrated straight into Salesforce.com.
