Commitment Accounting
Commitment accounting is a method that records financial obligations at the point an order is placed, not only when the invoice is received or paid.
When a purchase order is raised, commitment accounting reserves that amount against the budget straight away, treating it as committed even though no invoice exists yet. This gives managers a real-time view of remaining funds — budget minus actual spend minus outstanding commitments — rather than a picture that lags until suppliers bill.
The benefit is far better budget control: because committed money is visible immediately, teams avoid the trap of overspending on the assumption that funds are still free simply because invoices have not arrived. It is a core feature of many procurement and finance systems and works hand in hand with budget control at the approval stage.
