To grant access to the Subcontractor Portal for your suppliers and contractors navigate to Contacts > Suppliers / Contractors and select the relevant supplier/contractor. Alternatively, click the + Contractor / Supplier button in the top right of the screen to create a new supplier/contractor.
Once you have added the contractor or supplier, you can then add multiple contacts by navigating to the Supplier Contacts tab or Contractor Contacts tab and click the + Contact button.
Within the Add Contact side menu, click the tick-box next to Enable Portal Access.
JACK will send them an email invite to access the subcontractor portal, where they can view the tasks and documents you have chosen to share with them.
