Yes, as long as the payment hasn’t started processing yet.
To edit or cancel a payment:
Log in to your Casa account.
From your Home screen, tap the recent payment shown.
View your payment list and select the payment you want to change.
Choose Edit to update the amount, date, or payment method (if allowed by your property manager).
If changes aren’t available, tap Cancel and create a new payment instead.
Once a payment shows as Processing, it can’t be changed or canceled. You’ll still receive a confirmation email when it completes.
