The first key step of the purchasing process – is the identification of need – as we stated in our purchasing process video, typically this comes in two forms

1/ An internal request based on a requisition form
2/ A “buy” signal generated from the companies ERP/MRP system

Companies typically employ a purchase requisition process to “manage” these buy signals – allowing requests to be documented/tracked whilst following an appropriate approvals workflow. It’s important to differentiate this step in the buying process from raising an order – Purchase requisitions are not purchase orders and do not form a contract with a supplier for materials or commit money.

What actually triggers a purchasing requirement?

There can be various reasons for a company needing to buy something this could come from

• Materials needed for the manufacturing process
• Parts that are required to sell on to customers
• Safety stock
• Internal use / development needs
• New employees (e.g. requirements for IT equipment or office furniture)

Indeed –the signal to “go and buy” can come from almost anywhere (from requests for pens to requests for heavy machinery).

What is included in the Purchase requisition?

Whilst many requisitions simply state the product – depending on the end usage a requisition might need to be accompanied by various information from a technical specification to a concept to assist the buyer when seeking price and availability enquiries.

A purchase requisition will usually include key information such as

• What part/product is required
• How much of the part is needed
• When is it required by

Supplier selection

Whilst it is normally the role of the buyer to select the supplier that will be used – there is often input into supplier selection as part of the requisition process for example the requisition may stipulate proprietary items or the product may come from a vendor catalogue. Whatever supplier information is presented as part of this phase – final supplier selection is normally a procurement function.

To authorize or not to authorize – that is the question

Once a need has been identified that doesn’t necessarily mean that the purchase will proceed – there is usually an authorization process that accompanies the requisition phase – this is often a line manager or someone that has budgetary responsibility – they will verify a number of things before approval – for example

1/ Do I have budget funds for this item
2/ Is it completely necessary that we purchase the item
3/ Are we buying the right item
4/ Are we buying enough of the item

Once enough information has been gathered on the requirement and it has been approved it will usually be forwarded to the buying department for action.
