Daily takings is the end-of-day report: what came in, by payment type and by who took it, against what the invoices say. If the register doesn't match, this is where the difference shows.
What it shows
Daily takings lists every payment taken on one day at one location, grouped by payment method, for the end-of-day cash-up. Voided payments and reversals are left out; refunds are shown on their own so the register total is money actually taken. Payments made from a patient's account credit aren't money taken that day and are left out too.
Filters: a single date, a location. It needs the financial reports permission, which Administrators and Bookkeepers have.
Reading it
Headline figures: Total taken, Refunds.
Columns: Time, Patient, Method, Taken by, Amount.
Acting on it
Count the register against the Cash line and the terminal batch against the Card line. A difference usually means a payment recorded with the wrong method or not recorded at all; find it on the Payments page and void and re-record it, see Fix a payment recorded incorrectly.
