Your subcontractor submitted an invoice and you would like to request a lien waiver. Here's how you can do it.
First, you'll need to make sure you have a lien waiver template set up in the contracts module. This article covers how to set up your lien waiver template.
Once your template is set up, you can request lien waivers from the invoicing module. Head over to the Invoicing module and to the Lien waivers tab. Click "Request lien waivers' in the top right corner of your screen. 
Fill out the lien waiver request creating form with the following information:
- Project.
- Subcontractor.
- Invoice the lien waiver is related to (this is important to populate the right amount in the lien waiver).
- Lien waiver template: this is one of the lien waiver templates available in your contracts module.
This will create the lien waiver in draft mode and you'll be able to make any required changes before sending for signature. When you are ready, you can send the lien waiver request to your subcontractor in the top right corner: - Send: this will allow your subcontractor to request edits to the document. If they do, the document will be sent back to you for review, and you'll be able to accept or reject the requested changes.
- Send for signature only: this will NOT allow your subcontractor to request edits through Constrafor.
