Add approvers to an in-flight approval
Bring an extra approver into an approval that's already under review, without replacing the existing ones.
Sometimes a document under review needs another set of eyes — a manager's sign-off, a colleague who knows the vendor. Add Approver inserts an additional approver into the current step without removing anyone who's already there.
- The document is Under Review.
Add an approver
Open the document's actions
From the Approval inbox, open the document (or its More menu) and choose Add Approver.
Pick who to add
Select an approver from your organization's members.
Add a note and confirm
Optionally add a note, then Confirm. The document now waits on the added approver as well.

How the extra approver counts
Whether the added approver must approve, or only may, depends on how the step is configured:
- On a Joint approval step, everyone assigned — including the person you just added — must approve before the document moves on.
- On an Alternative approval step, any one assigned approver is enough.
These step types are set when an owner builds the flow — see Set up an approval workflow for a module.
To add an approver to many documents at once, use the batch tools in Batch-approve multiple documents.
