What it shows

  • Internal requisitions must stage against departmental budget holds.
  • Signoff processes require escalation paths when threshold amounts spike.
  • Transmitted POs lock supplier orders and decrement remaining fiscal budgets.

The takeaway

Hold budget allocation during approval to eliminate procurement overruns.
