CIPS Commercial Negotiation L4M5 Exam Dumps: Updated Questions & Answers (January 2026)

Buying organisation may increase its leverage with suppliers by concentrating spend. Supplier spend consolidation can take many forms as outlined below:

Vendor base reduction: straightforward reduction of number of suppliers in any category

Volume pooling: pooling cross organisational requirement until your order volume is high enough to attract new bidders/additional discounts

Volume redistribution: making recommendations following spend analysis to move from one supplier to another

Volume consolidation across categories: certain purchase requirements may be common across a number of categories

Standardisation and harmonisation of specifications: analysis of specifications and standards for a high spend purchased input, may show that there is a little difference between them and that the specification can be standardised or at least harmonised across the group or across national, regional or global operations.

Forming purchasing consortia: buyers may decide to come together and combine their purchase volumes to attract better deals.

Sally's objective is to achieve a 5% saving. If the supplier offers this saving in a different form (aftercare package), and the total value meets her goal, then accepting this alternative shows flexibility and supports a collaborative,win-winoutcome.

Tradeables—variables such as price, delivery, quality, and payment terms—are introduced in the bargaining stage of negotiations. This is the phase where both parties test positions, make concessions, and trade issues to create acceptable packages. Proposing and opening are earlier stages focused on setting out agendas and clarifying needs, while closure comes after tradeables are resolved. Introducing tradeables too early can weaken leverage, and leaving them too late risks deadlock. Bargaining ensures the structured exchange of concessions while protecting the overall bargaining mix.

Delivering on commitments is fundamental to building high-trust relationships. When an organization reliably fulfills its promises, it reinforces the supplier’s confidence in the partnership, fostering long-term collaboration. While contract management and audits are supportive processes, delivering on commitments directly strengthens trust, as emphasized in CIPS best practices for relationship management.

Absorption costing allocates indirect overheads to units, which is inherently judgemental; selecting allocation bases that “fairly” load overhead to products is the well-known difficulty. (By contrast, option B describes activity-based costing concepts—cost pools and drivers.)

Late paymentsdamage trust and strain supplier cash flow, becoming a direct source of conflict. Similarly, when gains, risks, or costs arenot equitably shared, perceptions of unfairness can destabilize the relationship.

“Persistent late payments not only threaten supplier cash flows but can significantly erode trust. Additionally, disproportionate sharing of risks or benefits can create resentment and hinder collaboration.”

To achieve a win-win (integrative) negotiation, Sally should accept the 5% discount on the aftercare package (B), as it meets her objective for a total discount while respecting the supplier'slimitations. This approach demonstrates flexibility and is in line with CIPS principles on integrative negotiations, where both parties achieve value in different forms.

In some markets, suppliers experience peaks and troughs in demand and so buyers can increase their leverage through developing an understanding of how busy their vendor are at particular time during the year or business cycle and targetting at quieter period. Similarly, if a buyer can develop an understanding of supplier capacity and to what extent have they covered their fixed cost, they may be able to target suppliers when their average costs are likely to be lowest. Vendor's average costs will be higher at low and high capacity utilisation.

When facing a monopoly supplier, buyers must find creative ways to introduce leverage. Publicly exploring alternative solutions can create the perception of competition or a fallback plan, thus shifting bargaining power slightly toward the buyer.
