Purchase order process

A simple purchase-order process that gives a small business control.

Purchase orders do not need to create bureaucracy. A simple process gives the business a record of what was requested, who approved it, what the supplier was expected to deliver and what was actually received.

1. Identify the need

Purchasing should start with a real requirement: stock replenishment, a customer job, a manufacturing material or an operational item.

Capture enough context that someone reviewing the order later can understand why it was placed.

2. Select the supplier and expected terms

Choose the supplier and confirm the products, quantities, expected prices and delivery expectations before issuing the order.

For recurring items, historical purchasing information can help staff identify unusual price changes or duplicated orders.

3. Create and approve the purchase order

The purchase order becomes the business's controlled instruction to buy. Use a consistent numbering and approval process appropriate to the size of the business.

Small businesses may use a simple manager approval while larger operations may need thresholds or role-based approval.

4. Receive against what was ordered

When goods arrive, compare the delivery with the purchase order. Record actual quantities received and note shortages or differences.

Receiving should update the relevant stock or material records rather than leaving the physical delivery disconnected from the system.

5. Resolve differences

Price, quantity and item differences should be investigated rather than silently adjusted. This helps prevent repeated supplier or internal errors.

Keep supporting documents associated with the purchasing trail where practical.

6. Review purchasing patterns

Over time, the purchase history can show which suppliers are used most, which items are frequently reordered and where buying decisions may need attention.

A structured process therefore supports both daily control and better management decisions.
