If you have multiple estimates for a job and your customer has accepted one
of the estimates, you might want to make the unaccepted estimates inactive.
When you make an estimate inactive QuickBooks keeps a record of it, but does
not use the estimate numbers in reports.
To do this task
Click Customer Center.
On the Transactions tab, click Estimates.
Double-click the estimate you want to make inactive.
On the Estimate form, click to clear the Estimate Active checkbox.
Click Save & Close.
