Your finance controller finds out the warehouse team overspent its supply budget after the vendor invoice already landed. The PO was confirmed, the goods received, the variance real. Without a hard gate on purchase orders, your spending policy is a suggestion, not a rule.

Purchase Order Budget Gate gives each department a spend ceiling enforced the moment a buyer clicks Confirm. Choose Block mode to hard-stop any PO that would push spend past the remaining balance, or Warn mode to flag the overage and let a manager approve or redirect. Either way, your controller knows before the invoice arrives, not after.

The remaining budget balance appears directly on the PO form and draws down in real time with every confirmed order. Buyers see exactly how much headroom is left before they raise an RFQ. No custom reports to build, no spreadsheets to maintain, no month-end calls explaining the variance to leadership.

Setup takes under five minutes: select a department, enter the date range and spend ceiling, then pick Block or Warn. Works with your existing Odoo departments on versions 16 through 19 with no extra configuration required. Install today and turn your spending policy into an actual rule.
