When using deferred charge (deposit or charge-later) pre-orders, PreProduct can delay charging and send an “upcoming charge” email to advise customers first.
By default this email won’t send as the delay time defaults to 0. You can change this from the “Deferred charge pre-orders” section of the “Setup” screen. Any positive number will enable the email and tell PreProduct the amount of time to wait between sending the email and triggering the charge.
Now, when you choose to charge customers, PreProduct will email all customers ahead of their credit card or PayPal account being charged.
