If you need to delete an estimate in Quickbooks, there are a few different ways to go about it. The first option is to go to the Estimates tab in your company’s account, select the estimate you want to delete, and click the “Delete” button next to its name. If you need to delete multiple estimates at once, you can use the “Select All” button on the Estimates tab. Then, click the “Delete” button next to each estimate’s name. If you need to delete an estimate that is stored in a past year but is still active in Quickbooks, you can use the “Undo” feature. To do this, open your company’s account and click on the Estimates tab. Next, select the estimate you want to undo and click on the “Undo” button next to its name. ..
