While I like the new online services, the add-ins that power them are not as quick and easy to set up in Office Accounting 2007 as I think they should be. They require many steps and a program re-start or two, so you really need to be committed to make them work.
While it's possible to use Microsoft Office Accounting on its own, the application really shines when integrated with other Microsoft Office apps. For example, you can use Microsoft Word to modify invoice templates and add one of the new PayPal payment buttons. Financial data can be transferred to Microsoft Excel, for flexible calculations.
Many of the program's accounting capabilities can also be accessed using the Business Contact Manager add-in to Microsoft Outlook. However, a beta 2 version of Outlook 2007 is required to support this integration, and I was not able to test it.
While Microsoft Office Accounting adds multi-currency support, the time-of-transaction conversion rate method used is too simple to satisfy many accountants, and it is inferior to foreign-currency accounting in Sage's Simply Accounting. However, these features in Office Accounting easily beat out similar features in QuickBooks, which assumes the rest of the world's currency doesn't exist.
Microsoft Office Accounting looks slick, with an informative company dashboard that summarizes business financial performance and to-dos. In general, the software narrows but does not eliminate the lead held by its leading small-business competitors, such as Sage's Peachtree. Despite enhancements in the latest versions of QuickBooks and Peachtree, Office Accounting still offers the best integration with Microsoft Office applications.
One caveat: I had to try three times before I successfully installed the beta, and it operates a tad sluggishly. I therefore don't recommend it for production use.
