You will need to bring your subcontractors onboard with Constrafor to execute contracts or request COIs.
To add a contractor to join your company for a project, click on the Contractors module at the top of the screen.
Next, click on the Invite company button on the right side of the page.
A box will appear prompting you to enter the name of the company and the email of the person who will be managing the Constrafor account for that subcontractor. After filling in that information, click Invite company.
