After a buyer sends a Purchase Order, the supplier must acknowledge receipt and confirm they can fulfill the order. Acknowledgment is the supplier's formal commitment to the order terms — quantities, pricing, and delivery dates.
Full acknowledgment confirms the entire order at once.
- The supplier opens the order and clicks Acknowledge Order.
- Optionally, they add a note and attach a confirmation file (e.g., an order confirmation PDF).
- The PO status changes from Waiting for Acknowledgment to On Track.
- The buyer sees the acknowledgment timestamp on the order detail page.
Once acknowledged, the order moves forward in the PO Lifecycle and the supplier can begin fulfillment.

When enabled for your organization, partial acknowledgment lets the supplier confirm individual line items rather than the full PO.
- Each line item has its own Approve toggle.
- A Select All / Approve All button is available for fast bulk acknowledgment.
- The supplier submits their selection. Approved lines are confirmed; unapproved lines remain open.
- The PO header displays a Partially Acknowledged status so both parties can see progress at a glance.
- Unapproved lines are still eligible for automated follow-up reminders.
- The supplier can return at any time to acknowledge the remaining lines.
The Orders page provides clear visibility into acknowledgment status:
- A Waiting for Acknowledgment state card on the dashboard highlights orders that still need supplier confirmation.
- Automated follow-up reminders are sent to suppliers if they have not acknowledged within a configurable period (typically two to three days after the order is sent).
- For partially acknowledged orders, buyers can drill into the Order Detail Page to see exactly which lines are confirmed and which are still pending.
When a supplier opens an order in the Supplier Order Portal:
- The Acknowledge Order button is displayed prominently at the top of the actions panel.
- All line items are visible for review before acknowledging.
- The supplier can attach an order confirmation document as part of the acknowledgment.

- Instead of acknowledging outright, the supplier may choose to propose changes by clicking Propose Revision. See Revisions for details on that workflow.
Once a PO is fully acknowledged, it progresses through production, shipping, and delivery stages. For the complete state flow, see PO Lifecycle.
