Accounting services pay special attention to your company's expenses—not bills that you enter and pay (though some support this), but rather other purchases you make. This is an area of your finances that can easily get out of control if you don't monitor it. So, small business accounting software separates them into expense types. Next, the software compares them to your income using totals and colorful charts. If you're traveling and have expenses on the road, you can usually take pictures of receipts with your smartphone and upload them to your accounting app. Some accounting services attach these receipts to an expense form. Others, such as Intuit QuickBooks Online and Xero, read the receipts and transfer some of their data (such as date, vendor, and amount) to an expense form using optical character recognition technology.
