If you believe an invoice has been paid by your client, and you wish to stop the reminders from Chasr, you need to log into your Xero.com online account and reconcile the payment against the outstanding invoice.
Once you have checked that payment has been made, you can add the transaction on Xero.com. We think its best to do this before proceeding in order to ensure that your Accounting records are accurate.
This will close the outstanding invoice and mark is "PAID" on Chasr. All reminders and notifications regarding this overdue invoice will no longer be issued.
