UPDATE: Sorry about that. The App World link said free but as the comments point out, it’s a 14 Day trial with a $7.95/month subscription.
EzBillMaker is a new free app on App World that lets users create bills, quotes, expense reports and timesheets. Once created, it delivers the fully-formatted documents to any fax or email. EzBillMaker also gives the user’s customer the option to pay their bill with a credit card in PayPal’s secure environment. User data is backed up on a secure server that also provides ad-hoc reporting and data export facilities.
