One door, two or three clinics. The person registers once, which is right. The mistake starts when each clinic has its own price slip and the cashier in the middle hears the numbers out loud. “Dermatology 200” is called from the door. The cashier writes 200 on the last open visit, which is the dental visit from the morning.
Each service sits on its own specialty’s visit
A complex lives on a shared desk and shared finance. That does not mean a mixed invoice. The dental visit has its services. The dermatology visit has its services. The cashier collects against the right open visit, and sees the specialty on the line, not in a colleague’s voice.
In Elite Care reception is shared and access to the file is not. The cashier does not need the skin diagnosis in order to collect the skin line. They need a visit, a line, and an amount. The end-of-day report can split by specialty without splitting the organisation into separate systems.
If each clinic insists on its own book because “the cashier gets it wrong”, the usual cause is that the line was never tied to a visit. The extra book hides the mistake. It does not fix it.
