PAGE: 7 USER PAYS ISSUES This is a User Pays Service as this represents a change to an existing service Who Pays? Transporters: – Common practice that when an invoice is issued there is sufficient supporting information to validate and pay the invoice – Could reduce invoice queries and disputes reducing xoserve’s workload? – If the implementation costs were very low the cost of invoicing may be greater than the value of the invoice? Shippers: – Supports their settlement and finance roles – Mod 640 designed to protect RbD Shippers
