The Purchasing Cycle: From Request to Supplier Invoice

A good purchasing process does not begin with the supplier invoice. It starts with a business requirement, approval, supplier selection, purchase order and receipt before accounting enters the picture.

Why does a business need a clear purchasing cycle?

When purchases happen only through calls and messages, it becomes difficult to know who requested the purchase, who approved it and whether received quantities match the order.

A structured purchasing process creates a clear trail.

Core stages of the purchasing process

Each stage has a separate purpose and the full process should not be reduced to a supplier invoice.
  • ✓ Internal purchase request.
  • ✓ Review and approval.
  • ✓ Supplier quotation or selection.
  • ✓ Purchase order.
  • ✓ Receipt of goods or services.
  • ✓ Supplier invoice.
  • ✓ Accounting review and posting.

Purchase request vs purchase order

A purchase request represents an internal business need.

A purchase order is the formal document sent to a supplier detailing items, quantities, prices and agreed terms.

Why connect receipt to the purchase order?

Connecting receipt to the order allows the company to compare what was requested with what actually arrived.

This helps identify shortages or excess quantities and supports invoice verification.

Where does accounting fit?

After receipt and invoice verification, the liability can be recorded according to company policy.

Keeping documents connected helps accounting understand the origin of each payable.
