Purchase Orders greater than €20,000 are not currently being published, a report found, however the Council disputes this statement
Carlow County Council chief executive, Kathleen Holohan, says the local authority has concerns over publishing Purchase Order details due to the "threat of cyber crime".
The concerns were outlined in the Audit Committee Report to Council on the 2017 Annual Financial Statement and Local Government Auditors Report.
Peter Scully, Audit Committee Chairperson, said "the Council currently has 71 Low Value Purchase (LVP) Cards in use. The 2017 LVP card spend was €528,000".
He added: "An analysis of this spend needs to be carried out to ensure that the aggregate spend on categories of goods and services procured does not exceed the relevant procurement thresholds.
"Contract Award Notices are not currently being published for tender competitions. Purchase Orders greater than €20,000 are not currently being published.
"This should be published on the Council's website on a quarterly basis.
"The above needs to be addressed by management."
In a written response, Ms Holohan said: "The Council has concerns about publishing Purchase Order details having regard to the threat of cyber crime. Payments made greater than €20,000 are published annually on the Council's web site."
A Purchase Order (PO) is a commercial document and first official offer issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services.
It is used to control the purchasing of products and services from external suppliers.
