The difference between a comma and a decimal point in bookkeeping is generally a large one. In U.S. accounting or bookkeeping procedures, a comma indicates a separation between the hundreds place and the thousands place. A decimal point indicates a separation between dollars and cents. When a number appears in QuickBooks that has a comma in the place of a decimal point, the problem is seldom with the QuickBooks software. Rather, it is with the Windows regional settings. The procedure you use to make this change is the same regardless of whether you are using the Premier 2008 version or a more recent version. If this box remains unchecked, the entry “12345” is the numerical equivalent of $12,345, as the program will assume the decimal point’s place is after the last number you entered. This is a possible situation where the decimal point/comma issue in QuickBooks relates to another issue than a comma placement issue. Tips Writer Bio
