The overhead workbook is an embedded Excel workbook and one is created for each estimate. Some sheets of this workbook are dynamically populated by QDV and can be seen as customizable pivot tables, allowing virtually any data to be collected from the estimate.

The workbook also contains custom sheets which are intended for reporting or for use with pricing calculation using data normally provided from sheets created through QDV.

Results of calculations from these custom sheets, including selling factors, risk factors, rates, etc. are returned back to QDV estimates which provides final pricing prices for each row which composes the estimate: you can provide any breakdown of the estimate in selling prices, regardless of the complexity in the calculation used to determine final pricing.
