If you have a PDF that might not need any editing once sent and needs to be sent in a hurry, you can create a PDF contract template.
To create the PDF template, go to Templates and click on Template library.
Choose the template called Standard PDF, confirm.
Once you confirm you will be directed to the template, here you can choose the appropriate settings (in the settings tab to the right), such as language, delivery method, signing method etc.
When you're done, go back to the main menu. click on New contract where your PDF template will be listed and ready to use!
