Account
An account is the financial ledger that gathers everything billable done for one patient at one facility into a single running balance. Charges flow into it, invoices are raised from it, and payments are settled against it — it is where the platform answers "what does this patient owe here, and what has been paid?"
Charge Item
A charge item is a single billable line for one service or product given to a patient — a consultation fee, a lab test, a dispensed medicine, a bed-day. It is the atom of billing in Care: the smallest unit that records what was charged, how much, and why, before anything is grouped onto an invoice.
Invoice
An invoice is the bill Care produces for a patient: it gathers the charges raised on an account into a single, numbered statement of what is owed. It is the moment billing becomes official — the point where running charges are frozen into a document the patient or payer can be asked to settle.
Payment Reconciliation
A payment reconciliation in Care is the record of a single payment made toward a patient's account — how much was paid, how, when, and by whom. It is how money received at the counter, online, or as a deposit becomes a traceable entry against what the patient owes.
