To mark a booking paid or settled with the artist or agent, you must first record a payment on the booking. Then go to Payment > Settlement > Record Settlement. We'll suggest an amount based on what has been collected and available. However, you can add any amount you'd like. 

You can record what payment method was used to pay the artist in addition to adding notes, attachments and a reference code or number. 

Once the payment is fully settled, enable "Settlement complete" to move the booking out from the 'Settlements' stage.
