Procurement & 3-Quote L1 purchase orders

Collect competitive vendor quotes, enforce L1 lowest-bid selection or exception rationale, and track PO payments.

The Purchase Order manager (in Project → Finance and Budget Reconciliation) provides finance and procurement teams with an append-only, server-owned audit trail of how vendors were sourced and awarded.

  • Collect competitive vendor quotes on a PO with private quote document uploads
  • Select the winning quote — if a non-L1 (not lowest-priced) vendor is chosen, you must record a mandatory exception_rationale and approver
  • Route POs through a governed lifecycle: Draft → Pending Approval → Approved → Sent to Vendor → Acknowledged → Partially Fulfilled → Fulfilled → Closed
  • Record partial or full payments against the PO and link related invoices
Note. Every quote upload, vendor award, L1 exception, approval, and payment is stamped into procurement_audit_trail.
