Sale Reports
Each sale has its own report: lots offered and sold, gross, buyer's premium, sales tax, fees, commission and what is due to consignors, plus lists such as lots with no bids.
The money figures come from the same places the money actually moves: buyer amounts from the invoices, consignor amounts from settlement. The report always agrees with those pages. Before the sale ends, the buyer's premium is an estimate from the sale's rate.
