Invoice Validation

Invoice validation enables Carrier/Client to identify where it is being overcharged by its Suppliers.

Invoice validation enables the Carrier/Client to identify where they are being overcharged by Suppliers of international voice minutes, and will challenge excessive invoices creating added book profit by way of received rebates.

TWS-PostNet will provide sufficient information, to enable the Carrier/Client to challenge its Suppliers when over-invoiced.

Optimisation services we will do this for both “Once-Off” and “Recurring” over-charging throughout the Carrier/Client complete system


We provide information on all Supplier overcharges to Carriers/Clients for onward dispute or handle the end-to-end dispute process on behalf of Carrier/Client to the Suppliers.

Suppliers overcharge for International Termination and Global Inbound traffic and are typically 10% to 20% of the average monthly Invoiced amount. We have identified and contributed to Cost Benefits as high as 80% on some International destinations.


We offer the initial Invoice Validation Service as a Gain Share. This means if TWS-PostNet doesn’t provide realized Cost Benefit to Carrier, there is no Cost.
