Hi there and let me help you today, Tiger7.

Each version of QuickBooks is designed to address specific business needs. And, our QuickBooks Online Accountant is designed specifically for accountants. It lets you easily connect with and manage your clients' QuickBooks data.

You get accountant-specific tools and reports to make your reviews easier. In QuickBooks Online Accountant, you can:

• Manage your client's books
• Access exclusive accountant tools.

For more information on how to use the program, visit the website and sign up whenever you're ready: QuickBooks Online Accountant.

Once you have access to QBO, you can migrate the QuickBooks Desktop file to the Online version. I'm adding these articles as your guide through the process.

• Move your QuickBooks Desktop file to QuickBooks Online
• Learn about converting from QuickBooks Desktop to QuickBooks Online.

Stay in touch with me if you need anything else with QuickBooks Online. I'll be around to provide the information that you need.
