  • The invoice number for an invoice that has an open balance
  • The current invoice balance
  • Your Company Number (also referred to as Account Number)

All this required information may be found on an invoice or on your customer statement. Be sure to use the most recent statement. After you successfully register, you will need to use your login credentials to log into MIA-Pay. See a sample Invoice and sample Statement below.
