FormCalc for QuickBooks

FormCalc enables you to do calculations in any QuickBooks form where items such as invoices, purchase orders, sales receipts, and others are used.
It works right there in the detail area of the QuickBooks form. You dont have to leave QuickBooks or go to a different window; just press a hotkey and FormCalc goes to work, adding the calculated results to your QuickBooks form.
FormCalc lets you choose the calculations you want to do on each form, and stores your calculation settings for up to 10 different forms and/or QuickBooks form templates. Available calculations include column-to-column calculations, totals and subtotals, item summaries and statistics, extended totals and subtotals, weighted averages, and more.
These let your forms have things like:
* Calculated columns.
* Nested subtotals--even for columns QuickBooks doesnt work with, like Quantity and Custom Field columns--such as separate billable hours subtotals for different employees or different types of services provided.
* A summary of shirt colors on a clothing order,
* Total shipping weight for an Invoice (calculated by multiplying each Items weight by its Quantity).
* Weighted average moisture content for truckloads of raw material.
* Automated labor calculations on Estimates (per-Item installation labor multiplied by the Quantity to be installed)
...and more.
FormCalc works with nearly all QuickBooks versions for Microsoft Windows, even including most older versions as well as many non-U.S. versions.
