Your company can obtain the banking information, or Telpay can.
Having the banking information for a biller is an advantage but not vital in order for them to receive payments for the first time.
What is needed:
1) Company Name
2) Full Address
3) Phone Number
4) Email Address or Fax #.
If there is no banking information, the initial bill payment will be a cheque mailed to the address provided. From that point on, Telpay sends a Biller Information form requesting the biller's banking information for them to receive payments electronically.
