It depends upon the commitment and preparedness of the leadership to make the public procurement efficient and corruption free.
The World Bank started bench-marking economies on the basis of legal and regulatory system, which can affect the ability of the suppliers to participate in public procurement process.
The other type is those who collect the tender notification from across the globe and make it available to all suppliers including from their home country.
A tender aggregator addresses various challenges like:non availability of data in a structured format, multiple languages and terminologies etc.
By making the tender notification information available to a wider supplier community, the tender aggregator plays an important role in making Public Procurement efficient and transparent, thus helping procurement entities spend tax payers' money judiciously.
However, due to the information often being second or third hand, some data can be lost in the process, or may become inaccurate as it is passed down the line.
Many governments have in the recent years actively published tender information in compliance with the Open Data Contracting Standard (OCDS), freely viewable by the public.
