A purchase requisition is an internal request asking for approval to buy specified goods or services. It records the business need, requester, quantity, estimated cost, budget, required date, and suggested supplier before a purchase order is issued to an external supplier.
Review points before the transaction moves
- Confirm the party responsible for the buying decision.
- Keep the source data and approval with the transaction.
- Record exceptions instead of silently changing the original instruction.
- Make the downstream owner able to reconstruct what happened without an email search.
The boundary worth keeping clear
The definition matters because nearby terms can describe a different document, event or responsibility. Use Purchase requisition only when the record matches the conditions above. A familiar label attached to the wrong stage creates cleaner-looking data and worse decisions. That discipline also makes reports comparable across teams, systems and reporting periods.

| Checkpoint | What the record should show |
|---|---|

| Handoff | Carry the approved result into the purchase order and supplier record |
The trade-off
More controls add work at the start. That cost is visible. The cost of weak records arrives later as rework, delayed approval, margin leakage, a payment investigation or a delivery dispute. Set the control depth according to the amount, risk and reversibility of the decision.
