Intuit has announced that customers using the company's online version of QuickBooks accounting software can now access their accounts on their BlackBerry and their iPhone.

Information Week reports that the application has an optimized interface for the mobile screen and customers can access it through a smartphone's mobile browser. Mobile users can check current bank and credit card balances, track who owes them money and who they owe, find vendor and contact information with addresses via Google Maps, and run QuickBooks balance sheets and profit and loss reports.

The mobile version of the QuickBooks online software is a product of the company's Intuitlabs.com, a site where customers are encouraged to try Intuit's releases and provide feedback. On the QuickBooks for iPhone page, the developers are already fielding multiple suggestions for improvements.

Yahoo News reports that Laura Olcott, treasurer for Twin Cities Co-op Preschool in Corte Madera, CA, said QuickBooks Online is perfect for her company because there is no "office," just volunteers working from home or work offices.

"Given the virtual nature of our interactions, iPhone support helps us be more productive," Olcott said. "While waiting for an appointment, I was able to check QuickBooks Online using my iPhone to look up parents with open balances and send them an e-mail reminder to pay their bill."

Intuit is referring to the new product as an early version Web-based mobile application.

QuickBooks Online costs $9.95 a month, and the company is offering a free 30-day trial. The BlackBerry and iPhone applications are free to QuickBooks online users.
