It happened before sunset. The service was recorded, the invoice was open, and the patient changed their mind. The fastest button on the screen is delete. The day closes and the numbers look clean. Weeks later, when someone reviews the movement, the deletion does not leave enough of a trace. The question is where the invoice went. The answer is “it was removed because the visit did not happen”.
A cancellation is a movement, not an absence
If an invoice was issued, undoing it is a credit note. The note points at the original invoice and the same visit, and it has a reason: the service did not take place, a line was wrong, or the money was returned. The drawer goes down by the amount. The report does not lose the line.
Elite Care raises that note from the same service chain, on the same day, before the employee leaves. A silent edit so the drawer matches is the thing to avoid. The drawer matches because the cancellation is written, not because the row vanished.
Access to the note is narrower than access to create the invoice. Reception may create. The financial reversal goes through whoever the organisation named. That procedure saves you from the delete button more reliably than a policy in a drawer.
