The "Hide Price" feature gives users the ability to send a PO to a supplier without disclosing the amount of the PO.
This is often the case when working with consultants and contractors. With a regular PO, the contractor sees the total amount of the PO, giving them an incentive to bill for the full PO amount. Now, without the value of the PO shown, it's easier to have the vendor accurately bill based on actual work performed, rather than meet the PO amount.
To enable this feature, create a support ticket.
Once the feature is enabled, a "Hide Price" checkbox will be available on the requisition header.
When an AP user flips a PO where "hide price" has been checked, the invoice defaults to 0.00.
This is expected behavior.
The supplier has no view of the price on the PO, so the amount invoiced may never be never exactly what was on the PO.
Coupa defaults the flipped invoiced to 0.00, because it is safer to force AP to double check the actual PDF invoice than to risk Coupa assuming the PO value is the same.
