Purchasing & Procure-to-Pay

Purchase Approval

Purchase approval is the authorisation step where a designated approver reviews and sanctions a purchase before it can proceed to order.

Purchase approval enforces control over spending by requiring the right person to sign off before money is committed. Approvers check that the purchase is needed, budgeted, correctly specified and compliant with policy and pricing. Approval limits are usually tiered so that larger amounts require more senior sign-off, following the organisation's delegation of authority.

Automated approval workflows route requests to the correct approver based on value, category or cost centre, capturing decisions in an audit trail. Efficient approval balances control with speed — too many steps slow buying and encourage workarounds, while too few invite maverick spend. Clear rules and digital routing keep approvals fast without losing governance.

Frequently asked questions

What is purchase approval?
Purchase approval is the authorisation step where a designated approver reviews and sanctions a purchase — checking need, budget, specification and policy compliance — before it becomes an order.
How do approval limits work?
Approval limits are tiered thresholds set by the delegation of authority, so higher-value purchases require more senior sign-off while smaller ones can be approved locally.
