If your clinic must handle a debt write-off for a patient, we would kindly record this via choosing the bad debt payment type:
1. Click 'Pay' on the invoice'
2/Select payment type and scroll down to choose 'Bad debt':
3. Click 'Submit'
This makes the invoice no longer outstanding but record it as a debt write-off.
Please note, when using this way to settle bad debt payments, when exporting a report do filter this column to ensure it does not effect your calculations.
