Make sure that there are no untranslated (empty or Draft) segments left in the files and make sure that the segments are in whatever final status they should be. If you're not sure what that is for your project, double-check your project instructions or with your PM.

If you are asked to sign off files, select all the files in the project and click Home > Open For Sign-off. This will open the files in a combined view, where you can click Complete Sign-off to change the status of all segments in the opened files.

The delivery method depends on the way you originally received the project.

Go to the Projects tab, right-click the project and select Create Return Package. Include all the file that you want to deliver (usually every file in the package). Select location where you want to create the return package and click Finish.

Send the return package (.sdlrpx) to your PM.

Simply notify your PM that you are ready.

With the file open in the editor, go to File > Save Target As (or click Shift + F12).

Save the translated file in the original format (.mqxliff or .mqxlz) and send it to your PM.
