A school bus pulls in, the coordinator says “we’re the 10:30 group,” and a staff member checks in the reservation. Ten minutes later it turns out the real 10:30 group is still on the highway, and the bus at the curb belongs to a different school. Now the wrong reservation shows as arrived, and someone asks the obvious question: how do we take that back?
Undoing a group check-in in Altru is less straightforward than most people expect. This article covers what to try, what to do when there’s no clean undo, and how to keep it from happening so often.
First, figure out what “checked in” actually changed
Before you try to reverse anything, look at what the check-in did to the reservation. Depending on how your organization uses group sales, checking a group in can affect:
- The reservation’s status (for example, from confirmed to arrived).
- Attendance or ticket counts that feed your daily and group sales reports.
- Any balance due, if the group paid at arrival rather than in advance.
- Capacity for the time slot or program, if your setup ties capacity to check-in.
The fix depends on which of these moved. A status flag with nothing attached is a minor annoyance. A check-in that also took a payment is a revenue question, and it should go to whoever reconciles your batches.
Is there a built-in way to undo it?
Honestly, it depends on your Altru version and your security settings, and we’d rather tell you that than guess. Some organizations find they can change the reservation’s status back or edit the arrival details from the reservation record. Others find the option isn’t there, or that only certain system roles can see it.
To find out for your own setup:
- Test in your sandbox or a test reservation. Create a fake group, check it in, then look at every action available on that reservation. Do this with an administrator login and with a typical front-desk login, because the answer may differ.
- Check your security roles. If an admin can edit the reservation but desk staff can’t, that may be the right setup. Reversals are a reasonable thing to restrict.
- Ask Blackbaud support. Give them your version and describe exactly what happened. Ask specifically whether reversing an arrival is supported and what it does to reports.
When there’s no clean reversal
If you can’t undo the check-in directly, you still have options. None of them are elegant, but they keep your records honest.
Correct the record and leave a note
If you can edit attendance counts or reservation details, set them to reflect what really happened and add a note on the reservation explaining the change, who made it, and when. Anyone looking at that group later should be able to tell it was a correction and not a data entry mistake.
Handle money separately
If a payment was taken during the mistaken check-in, process it through your normal refund or adjustment workflow. Don’t try to make the revenue disappear by editing the reservation. Your finance team will want the refund visible in the batch, not hidden.
Check the real group in when it arrives
Once the correct group shows up, check them in as normal. If the wrong reservation still shows as arrived, keep a short list of corrected reservations so the person running end-of-day or month-end reports can account for them.
Adjust your reporting, not just the record
If your attendance reports pull from check-in data, one mistaken arrival can inflate the day. A simple query of group reservations with a note or attribute marking “check-in corrected” lets you exclude or flag them without rebuilding the report each time.
Prevent the mix-up at the door
Most mistaken group check-ins come from the same few causes. A few habits cut them down considerably:
- Confirm two details, not one. Arrival time alone isn’t enough when several groups share a slot. Ask for the group name or the coordinator’s last name, and match it against the reservation before checking in.
- Use the reservation or confirmation number. If your confirmations include one, ask coordinators to have it ready on arrival.
- Check in at the count, not at the curb. Wait until you’ve confirmed headcount and chaperones. Many errors happen because staff check in as soon as the bus is spotted.
- Name a go-to person for corrections. Decide who is allowed to fix a mistaken check-in and how. A seasonal staffer improvising a fix usually creates a second problem.
Write a short correction procedure
Whatever you learn from testing, put it on one page and keep it with your group sales materials. It should say who can reverse or correct a check-in, what to do when a payment was involved, what note to leave on the reservation, and who to tell so reports stay accurate. When it happens again, and it will, nobody has to work it out from scratch with a bus full of fourth graders waiting.
Quick answers
Can front-desk staff undo a group check-in?
That depends on your security roles and version. Test with a desk-level login in a sandbox to see what they can actually do.
Will correcting a check-in change past reports?
Reports that run after the correction should reflect it, but anything already exported or shared won’t update. Let whoever owns attendance reporting know about the change.
