BIS requires that a purchase order must be issued to a supplier before any commitment to purchase goods or services is made on behalf of BIS.
To facilitate payment, suppliers must quote the relevant purchase order number on all invoices. Invoices must be addressed as instructed on the purchase order.
BIS pays suppliers in accordance with our contractual commitment. Our standard payment terms for suppliers are 30 days from the end of the month in which the tax invoice is dated.
Please refer to the BIS Purchase Order Terms and Conditions for further details.
