Matches could include a 3-way match based on invoice, purchase order and goods receipt /service receipt or a 2 way matching based on the invoice and purchase order.
Match refers to the comparison of the quantities, price per unit, terms, etc. appearing on the invoice to the information on the purchase order and to the quantities actually received. After the electronic invoice has been validated by the three-way match, it can be further processed for payment. The three-way match is an important step in safeguarding an organisation's assets.
