External Reviewers
Invite a principal contractor or client outside your company to review and approve a workpack, and learn how invited reviewers find and action their work.
External Reviewers
Some workpacks need a sign-off from someone outside your own company — most often the principal contractor or client reviewing a subcontractor's Inspection & Test Plan. External reviewers let you add those people to a workpack's approval chain by email, without first setting them up as members of your team. They receive a secure, password-free link, open just the workpack they were invited to, and record their approve-or-reject decision.
This page covers both sides of that exchange: the host who invites a reviewer, and the reviewer who receives the invitation.
For the Host: Inviting an External Reviewer
External reviewers are added the same way as internal approvers — through the approval chain on the workpack. See Approvals & Sign-Off for the full picture of how the chain works; this section focuses on the external part.
Add an external approver to the chain
You build the approval chain while the workpack is still in draft. On the workpack's detail page, find the Approval Chain card.
- Click Add approver to create a new step in the chain.
- In the step's type dropdown, choose External (the alternative is Internal, for someone already on your team).
- Enter the reviewer's email address. This is the address the invitation will be sent to, so check it carefully.
- Optionally enter a role (for example, "Principal Contractor" or "Client QA") so everyone can see who this step represents.
- Use the up and down arrows to position the step in the order you want decisions to happen.
- Click Save to store the chain.
You can mix internal and external steps freely, and add as many as the review process needs. Each step in the chain decides in sequence.
Send the invitations
Adding an external email to the chain does not contact anyone yet — it only records who will be invited. The invitations go out when you submit the workpack for approval.
- With the chain saved, click Submit on the workpack.
- In the submit dialog, choose how much the reviewers will see (this is the visibility setting):
- Approval only — the reviewer sees the workpack as it stands at submission, so they can make their decision. This is the default.
- Ongoing — the reviewer keeps visibility of the workpack as it continues to progress on site after approval.
- Click Confirm to submit.
On submit, each external email in the chain receives an invitation to review the workpack. Once the workpack is submitted, the chain becomes read-only — you can no longer freely re-order or edit steps.
Replacing or correcting a reviewer
If you submitted with the wrong email, or a reviewer needs to be swapped out, you don't have to start over. On a submitted workpack, any step that is still pending shows a Replace action.
- Click Replace on the pending step.
- Choose whether the replacement is Internal or External, and enter the new person or email.
- Optionally adjust the role.
- Enter a reason for the change — this is required and is recorded on the workpack's audit trail.
- Confirm. The new reviewer is invited in place of the old one.
Steps that have already been approved or rejected cannot be changed.
For the Reviewer: Receiving and Actioning an Invitation
If you've been named as an external reviewer, you don't need an existing account or a password to take part.
Opening your invitation
You'll receive an email invitation to review a workpack. Opening the secure link in that email signs you in automatically — there's no password to create or remember. If a one-time code is requested, enter the code from the email to confirm it's you.
This sign-in is scoped to the work you were invited to. You will not see any of the host company's other projects, workpacks, or data — only the workpacks that have been shared with you.
Finding workpacks shared with you
Once signed in, the workpacks awaiting your attention appear in the Incoming view. Each row shows:
- Name — the workpack's title; click it to open the full workpack.
- Project — the project the workpack belongs to.
- Status — where the workpack currently sits in its lifecycle.
- Last edited — when it was most recently updated.
When a workpack is waiting specifically on your decision, the row is flagged with an Action required badge so you can tell at a glance what needs you next.
On a phone, the table keeps the name and the action flag in view and tucks the project and last-edited details away on wider screens, so you can triage from the field.
Reviewing and deciding
- From the Incoming view, click the workpack name to open it.
- Read through the workpack — the inspection items, attachments, and any history are visible to you.
- When you're ready, record your decision:
- Approve — sign off using the on-screen signature pad, and optionally add comments. A signature is required to approve.
- Reject — send it back with comments. A short explanation (a sentence or so) is required so the host knows what to fix.
Your decision moves the workpack to the next step in its chain, or completes the approval if you were the final reviewer. What you can do is limited to reviewing and deciding — external reviewers don't edit the workpack's content or manage the team.
