how do i remove "estimate" from my proposals ??

We can remove the automatic prefix of Estimate to your subject lines, @SnowGhost so that your customers will know that it is a proposal not an estimate. 

In QuickBooks Online (QBO), you'll need to customize the labels and titles on your sales forms to remove the automatic "Estimate" prefix from the subject lines in your proposals.

To do so, here's how:

1. Go to the Gear icon.
2. Under the Your Company column, choose Custom Form Styles.

      3.Click the New Style dropdown menu, then select Estimate

      4.From the Content tab, click the Pencil icon of the header part.

      5.In the Form section, uncheck the Form Names to remove the word Estimate.

      6.Proceed to the Emails tab, then modify the Subject section.

      7.Hit Done.

Now, when you create a new proposal using the customized form style, it should display without the "Estimate" prefix or with the new title you specified.
