I agree with Suzi, 710 wouldnt apply to an SMS as its a prompt and you should still issue your reminder notice as normal.
At Wollongong we used to send an SMS reminder out 2 days before the payment due date to let them know the instalment was due for payment soon. Ratepayers opted into this, and it was built into our e registrations. As in a customer could tick to register to receive notices electronically and also sms notifications from council (t&C applied that was approved by legal)
We used to run a file to show customers with outstanding balance, remove those with a direct debit debit in place then wash it against the registrations. Our former print house PML would send them on our behalf.
