Purchase Order (PO) Approval Software for Xero and QuickBooks

Every purchase is requested, approved, and checked against budget before a PO is raised. When the supplier’s bill arrives, it’s matched to the approved PO before anything is paid.

What is a purchase order approval workflow?

A purchase order (PO) approval workflow is the set of checks a purchase goes through before a PO goes to a supplier. The right people review the request, it’s checked against budget, and only then is it turned into a purchase order.

Without one, POs get raised on a verbal “yes”, approvals get lost in email and chat, and you find the budget blowout at month end. With one, spend is controlled at the point it’s committed, not after the bill has already landed in Xero.

How the PO approval process works in ApprovalPro

One flow from purchase request to paid bill, with nothing re-keyed along the way.

  1. Request

    Staff raise a purchase request and attach quotes, before anything is ordered.

  2. Approve

    The request goes through your multi-tier approval workflow, with an email to each approver.

  3. Check budget

    Approvers see the budget impact before they sign off, while there’s still time to say no.

  4. Raise the PO

    The approved request becomes a purchase order in Xero or QuickBooks automatically.

  5. Match the bill

    The supplier’s bill is matched to the PO and held until it’s approved.
