Purchase requisition: the start of every purchase

A purchase requisition is an internal request for approval to purchase something. When a team member identifies a need — new equipment, consumables, a service — they complete a requisition describing what is needed, how much, why, and which budget it should come from. That request then goes to the people authorised to approve spend of that type and size.

The key distinction is that a requisition is internal and a purchase order is external. A requisition asks 'may we buy this?'; a purchase order tells a supplier 'we are buying this.' Nothing is committed to a supplier until the requisition is approved and converted into a purchase order. This separation is what gives the organisation a checkpoint to control spend before money is committed.

A good requisition captures enough detail for an approver to make a decision without chasing information: a clear description, quantity, estimated cost, the budget or cost centre, the business justification, and often a preferred or contracted supplier.

The requisition process is the front end of procure-to-pay. Done well, it captures the right information once and routes it cleanly, so approval and ordering are fast.

The requisition is the control point before money is committed. It is far easier to question, redirect or reject a purchase at the requisition stage than after a supplier has been told to proceed. A disciplined requisition process is how organisations enforce budgets, keep buying on-contract and prevent maverick spend before it happens.

It also creates the record everything else depends on. A clean requisition — with the right budget line, justification and supplier — flows straight into an accurate purchase order and, later, a clean three-way match. Weak or skipped requisitions are a common root cause of downstream problems: budget overruns, off-contract buying and invoices that cannot be matched. Standardising the requisition, ideally through a self-service catalogue where items and prices are pre-approved, removes most of that friction.

A site supervisor needs safety consumables. Rather than calling a supplier directly, they raise a requisition specifying the items, quantities, estimated cost and the maintenance budget line, with a short justification. Because the amount is within the supervisor's manager's authority, it routes to that manager, who approves it the same day. The approved requisition converts into a purchase order automatically.

The difference a good process makes is speed with control. If the items sit in a pre-approved catalogue with contract pricing, the requisition is a few clicks, the cost is already known and correct, and the budget check is automatic — so approval is quick and the resulting purchase order is accurate. Malaysian organisations that move requisitions onto a managed catalogue in this way remove most of the back-and-forth while keeping every purchase inside budget and on-contract. Use the requisition template linked below to standardise the form if you are still on spreadsheets.

A purchase requisition is the internal request for approval to buy — the control point before any commitment is made to a supplier. It captures the need, cost, budget line, justification and preferred supplier, then routes for sign-off, and once approved becomes a purchase order.

A disciplined requisition process enforces budgets, curbs maverick spend and produces the clean record the rest of procure-to-pay depends on. Standardising the form, checking budget up front, requisitioning from a catalogue and automating routing keep it fast enough that people actually use it.
