How long does an Invoice Approver have to approve, reject or comment on an invoice?

Departments have 7 days to complete receipt and invoice approval. If receiving takes up the full seven days, the Invoice Approver will be provided no more than 3 additional days to approve, reject or comment on the invoice before it is processed by the Invoice Settlement team. If no receipt is required, the Invoice Approver has 7 days to approve, reject or comment on an invoice.
