FormCalc does calculations in any QuickBooks form where Items are used. It works right there in the form--you don't have to leave QuickBooks. FormCalc can give you: * Calculated columns * Column totals and subtotals * Item size/color/count summaries * Total shipping weights * Automated Estimate calculations ...etc. FormCalc works with most versions of QuickBooks for Windows, including most old versions and non-US versions.
