Becoming a preferred customer to supplier's perspective can increase the purchaser's leverage in negotiation. Beside the size of buying organisation or its spend, the following may be sufficient to differentiate the buyer from other buying organisations:

- Simple procurement processes

- Simple contracting processes

- Clear and concise documentation

- Absence of onerous supplier terms and conditions (onerous supplier terms and conditions mean that obligations imposed on suppliers are greater than their gains)

- On-time payment: The reduction in hassle for both supplier and the buyer, if bills are paid on time, is significant. From the customer’s perspective it could also be the opener to agreeing preferential payment terms. A supplier may weigh up that payment on time at 60 days is worth taking, over the current 30-day terms that slip to 90 days and beyond.

- Transparent processes

- Ethical behavior
