The National Board of Revenue (NBR) will upgrade the UNCTAD software by September next year to make the system more robust against underinvoicing in external trade, NBR officials said.

Underinvoicing is an illegal practice to dodge the correct duty on imported products by quoting an incorrect price.

The move comes in response to a claim from a former central bank governor that the country was incurring huge revenue losses due to NBR's failure to detect under-invoicing.
