A supervisor can read your workforce roster, confirm work, and report a late, an early finish or a no-show. A supervisor cannot send records to people who have no Credda account, and cannot see the analytics columns on any plan, including the most expensive one.
The seat exists because the owner is not in the room when the work happens. The head chef, the duty manager, the night lead, the senior carer on the round: those are the people who actually saw the shift.
What a supervisor can do
Read the workforce roster. The people, and the record of what has been confirmed about them here.
Confirm work. The ordinary confirmation, exactly as an owner or admin would do it.
Report an adverse outcome. Late, Left early and Did not turn up are all available to a supervisor. This is the load-bearing one. A shift lead is usually the only person who witnessed a no-show, so leaving them out would mean the adverse half of the record could only be entered by somebody who was not there. The rules do not soften for a supervisor: a written reason is still required, the second confirmation step is still required, and adverse recording is still on the Business plan.
What a supervisor cannot do
See work scores or any analytics column, on any plan. This is not a paywall. Buying the Business plan changes nothing for this seat. A supervisor should never be shown an upgrade prompt for it, because upgrading would not grant it. It is a decision about how much one seat should be able to watch, not a price.
Record a shift for somebody who has no Credda account. Staging a record sends an email on the company's behalf to a person who never signed up for anything. That is a decision about how the business represents itself, not something you witnessed on a shift, so it belongs to an owner or an admin.
See colleagues' scores. A supervisor is refused the team score views whether or not the organization has turned on colleague visibility. The supervisor check runs first, so the setting can only ever narrow a door that is already open.
When a supervisor tries one of these, they get a message saying the action is outside a supervisor's scope. That is the seat working as intended. It is not a bug and it is not a billing problem, so there is nothing to fix and nothing to buy.
Choosing between supervisor and admin
If the person needs to send record invitations to workers who have not signed up, or needs the analytics columns, they need admin. If they need to record what happened on their own shift, supervisor is the right seat, and it is the narrower one, which is the point of having it.
A care agency with four coordinators and one registered manager usually wants the manager as owner or admin and the coordinators as supervisors. Each coordinator can confirm the rounds they oversaw and report a missed one, and none of them can mail a stranger on the agency's behalf.
Seats cost money on a paid plan
Every accepted membership is a billable seat on a paid plan, whatever the role, supervisors included. A pending invitation is not a seat, because it may never be accepted. A free organization is never billed for anybody.
The bill can always come down. An owner or an admin can remove a member, and any member can leave. The seat count you are shown before you pay is the same number your card is charged for, because it comes from one calculation. Who counts as a billable seat has the rest.
