Key Takeaway: Every purchase moves through the same basic stages whether or not anyone's tracking them formally. Naming the stages is what makes them manageable.
What's on This Page
The Stages
- Requisition: identifying the need to buy, ideally from a reorder point trigger rather than a guess
- Purchase Order: a formal, numbered document specifying exactly what's being ordered (see Purchase Orders Explained)
- Receiving: checking delivered quantity and condition against the PO
- Invoice Matching: comparing PO, receiving record, and supplier invoice before paying (3-way match)
- Payment: released only once everything matches
Why Formalize Every Stage
Skipping stages is where duplicate orders, overpayment, and unverified deliveries happen. A wholesaler eliminated duplicate purchases almost entirely simply by centralizing visibility into the requisition and PO stages. See the case study.

Checklist
- Confirm requisitions are triggered by real reorder points
- Ensure every order gets a formal, numbered PO
- Check delivered quantity and condition at receiving
- Match PO, receiving record, and invoice before payment
- Release payment only once all three documents agree
- Review the full cycle periodically for skipped or informal steps
Common Mistakes
FAQ
What are the core stages of the purchase cycle?
Requisition, purchase order, receiving, invoice matching, and payment. Skipping any stage is usually where disputes and overpayment start.
Why does formalizing every stage matter for a small business?
Because that's exactly where duplicate orders, overpayment, and unverified deliveries happen when a stage gets skipped informally.
Does the purchase cycle need to be complex to be effective?
No. Even a simple, five-stage process run consistently prevents most of the common purchasing mistakes.
What triggers the requisition stage ideally?
A calculated reorder point, not a visual check or a guess, so the cycle starts from real data rather than instinct.
