The new Xactimate online Estimate Writer

Updated by Jill Bowers

As part of our update to Xactimate online (, we’ve created the new Online Estimate Writer for Windows powered by Xactimate desktop code. The Online Estimate Writer is simple. You only need to install it once, and it’s self-updating, so you won’t need to worry about manually downloading new releases or program updates.   

To use our estimate writer, you need to install the Xactware ClickOnce extension in your browser. If you do not have rights to install extensions, you may need to contact your system administrator. 

Once you have the extension ready, you can open projects in Xactimate online via the project list. To do this, double click a project or highlight it and select Open from the action bar.   

The first time you open a project in the new Xactimate online, you’re prompted to install Xactimate online Estimate Writer. When installation is complete, your project opens as a Windows application you can see on your windows taskbar.  

When you finish working, simply save and exit or mark the project complete. Your work automatically saves to Xactimate online.
