Teachworks allows you to send a receipt email to customers when a payment has been received or recorded for their account. Payment notifications are set in your companies Account Settings:
Go to the Account & Settings tab and click on Account Settings
Scroll down to the Invoice Settings section and set the Payment Received Email to "Enabled".
Save the form.
If you accept payments online and a customer makes a payment or if you use the Bulk Invoice Payments feature the payment received email will be sent after the successful payment.
If you are manually recording or processing a single payment, you'll see a checkbox on the payment giving you the option to send the receipt email.
You can customize the Payment Received template by following the instructions here: Customizing Notification Templates.
