The two-key package check

The situation

A prepaid balance lives in the client record; equipment use lives in an appointment or device log. When those sources are never compared, a completed session can remain absent from the package balance without anyone deliberately taking it.

The common mistake: making reception memory the package ledger

A prepaid package is a commitment to deliver defined services under agreed conditions. When consumption is updated only if someone remembers during a busy checkout, the balance can drift away from the services delivered.

The answer is a second evidence source and a documented reconciliation process, not suspicion or pressure on staff.

The method: two keys — balance and verified use

Each prepaid equipment session should have two records that can be reconciled.

• Key 1 — Package consumption: record the completed session against the agreed balance at checkout, with a documented reason for any exception.
• Key 2 — Verified treatment use: match the session to its appointment and, where safely available, the relevant device log or runtime record.
• Weekly review: compare verified treatments with package consumption. Investigate differences by date and time, preserving the explanation and correction.
• Fair-process rule: explain the control to the team, limit access appropriately and use the data to improve the process. Do not treat an unexplained difference as proof of misconduct.
