BUY-SIDE NEGOTIATION SUPPORT
The negotiation phase is where most value is won or lost
A well-run sourcing process can be undone in the negotiation phase. Vendors arrive prepared — with experienced commercial teams, pre-rehearsed concession strategies, and a precise view of their walk-away position. Most FS procurement teams are managing multiple competing priorities at this very moment, and the commercial intensity of a major vendor negotiation is often underestimated until it is too late to correct.
Wilverley provides independent commercial negotiation support that rebalances the table. We prepare your team, lead or shadow the commercial workstream, and ensure that the outcome your sourcing process earned is the outcome your contract reflects.
WHAT HAPPENS WITHOUT INDEPENDENT SUPPORT
Stage 1
Vendor arrives prepared
The vendor's commercial team has negotiated dozens of deals like yours. They have a playbook, a concession ladder, and a clear red line. Your team may have run one negotiation of this scale in the past five years.
Stage 2
Pressure mounts
Timeline pressure, stakeholder expectations, and the cost of delay create leverage for the vendor. Concessions are made incrementally, each one individually defensible, collectively significant.
Stage 3
Value leaks
Industry research estimates 9–15% of contract value is lost in negotiation. On a £30M contract that is £2.7–4.5M, value that was earned in the sourcing process and surrendered at the table.
Stage 4
Contract misses the deal
Even when commercial positions are well held, the final contract frequently fails to reflect what was actually agreed. The legal drafting phase is a second negotiation that many clients do not realise they are in.
WHAT THIS ENGAGEMENT COVERS
Negotiation strategy
Building your full negotiation plan before the first session — defining commercial priorities, establishing your concession ladder, identifying leverage points, and preparing specific responses to the tactics the vendor is likely to deploy. We know those tactics because we help vendors develop them.
Commercial benchmarking
Independent benchmarking of the vendor's commercial proposal, pricing levels, payment terms, service level structures, risk allocation, and penalty regimes against current market standards and comparable deals we have seen on both sides of the market.
Stakeholder alignment
Ensuring your negotiating team enters every session with a unified, briefed commercial position. Vendor teams look for inconsistency between your stakeholders. We remove it before they can find it.
In-negotiation support
Active support during commercial sessions, advising in real time on positions and proposals as they emerge, reviewing vendor offers before your team responds, and ensuring no value is conceded in the room that did not need to be.

THE DUAL-SIDE ADVANTAGE — IN PRACTICE
Wilverley also advises technology vendors on how to approach financial services negotiations, including concession strategy, pricing floor setting, and reading the buyer's commercial signals. That means we bring direct, current intelligence about the specific commercial dynamics on the sell side into every buy-side engagement. This is not a theoretical advantage.
"We advise technology vendors on how to approach financial services negotiations. That means we know the tactics, the pressure points, and where the real flexibility sits — before we sit down on your side of the table."

What vendor commercial teams typically do, and how Wilverley prepares you to respond
VENDOR TACTIC
Anchor high on price, then offer structured discounts tied to volume commitments or contract length, making the discount feel like a concession when it is priced in from the start.
WILVERLEY PREPARATION
We benchmark the opening position against market before the first session, so your team knows the real discount to market, not the discount to the vendor's anchor.
VENDOR TACTIC
Introduce timeline pressure at key milestones, board approvals, budget cycles, resource availability, to force commercial concessions under urgency that is often manufactured.
WILVERLEY PREPARATION
We map your timeline against the vendor's real pressures, their quarter end, their revenue targets, their competitive situation, and identify where the genuine urgency sits and where it does not.
VENDOR TACTIC
Disaggregate commercial positions across multiple workstreams, legal, commercial, technical, SLA, and trade across them in ways that appear balanced but systematically favour the vendor.
WILVERLEY PREPARATION
We maintain a holistic commercial scorecard across all workstreams so your team can see the aggregate position at any point, and trade across workstreams deliberately rather than reactively.
VENDOR TACTIC
Use the legal drafting phase to re-open commercial positions that were agreed in negotiation, reframing them as clarifications or drafting issues rather than commercial changes
WILVERLEY PREPARATION
We document commercial positions formally at each session and conduct a commercial integrity review of the final contract before signature, catching every re-opener before it becomes binding.
HOW AN ENGAGEMENT WORKS
1 Commercial position assessment
We review the vendor's proposal, your current commercial position, and the negotiation history to date to establish a baseline understanding of where value has already been conceded and where it remains to be captured. We are direct about what we think is achievable from this point.
2 Benchmarking and strategy development
We benchmark the vendor's commercial proposal against the market, develop your negotiation strategy, and build the concession plan, establishing what you are willing to trade, in what sequence, against what return. This is done before the first session, never during it.
3 Team preparation and rehearsal
We brief and align your negotiating team, covering the strategy, the vendor's likely approach, individual roles in the room, and responses to the specific tactics we expect the vendor to deploy. Where helpful, we run a rehearsal session before the first commercial meeting.
4 Active negotiation support
We attend commercial sessions, in the room or immediately available by phone, advising in real time on positions, proposals, and tactics as they emerge. Between sessions, we review what was agreed, what was conceded, and what the next session needs to achieve commercially.
5 Contract integrity review
Once terms are agreed, we conduct a commercial review of the draft contract, checking that every position agreed in negotiation is accurately reflected and that no commercial dilution has been introduced in the drafting. This step is included in every engagement.
FEE STRUCTURES
£40–120K
Fixed fee. For programmes already at BAFO or shortlist stage where commercial negotiation support is the specific requirement. Covers strategy, preparation, active in-negotiation support, and contract integrity review. Scoped to the complexity and expected duration of the negotiation.
From £25K
Fixed fee. For in-flight contracts requiring renegotiation — scoped separately based on contract value, complexity, and the specific commercial issues to be resolved. Can be combined with an ongoing retained advisory arrangement.
£75–200K
Fixed fee or time-and-materials. Full engagement covering both the sourcing programme and the negotiation phase. Negotiation support included as part of the complete sourcing engagement — not priced as an add-on.
Outcomes-based fee structure
We offer an outcomes-based uplift on all negotiation engagements, our additional fee is tied to verified savings against a pre-agreed commercial baseline. We are willing to put our fee at risk against the outcome because we are confident in the value we deliver. The baseline and verification methodology are agreed before work begins, independently of the negotiation itse

WHY CLIENTS CHOOSE WILVERLEY FOR NEGOTIATION
We know the other side
Wilverley advises technology vendors on their FS commercial strategies. We know how vendor commercial teams prepare, what their real priorities are, and where they have flexibility that they will not volunteer. This intelligence is current and specific, not generic market knowledge.
FS-only focus
Our buy-side practice is exclusively Financial Services. The dynamics of FS technology negotiation, regulatory context, supplier leverage, internal governance, and risk appetite are specific to the sector. Our advice is calibrated to that context, not adapted from a generalist playbook.
No conflicts of interest
No vendor relationships, preferred supplier panels, or commercial arrangements that create an interest in any particular outcome. Our only commercial interest is the savings we help you achieve, and when we structure an outcomes-based fee, that alignment is explicit and contractual.
Outcomes-based by choice
We offer to put some of our fee at risk against the outcome of every buy-side negotiation engagement. We do this because we are confident in the result, not because we are required to. If you want us to be held to the outcome, we will agree to it before work begins.
COMMON QUESTIONS
Our negotiation has already started. Can you join mid-process?
Yes — and this is the most common entry point for a negotiation-only engagement. We review the negotiation history, establish what has already been conceded and what remains to be captured, and build a strategy from the current position. We are direct about what is still achievable from where you are. The earlier in the process we are involved, the better the outcome, but late involvement is significantly better than no involvement.
Our internal team is experienced. What does independent advisory add?
Experienced internal teams know their own organisation well — their risk appetite, their stakeholders, their priorities. What they typically lack is up-to-date intelligence on how the specific vendor on the other side of this negotiation is operating, what they are offering to other clients, and where their commercial flexibility actually lies. That is what we add. The most effective negotiation teams combine internal knowledge with independent market intelligence.
Can you advise on a renegotiation without having been involved in the original negotiation?
Yes. We regularly advise on renegotiations of in-flight contracts where we had no prior involvement. We review the existing contract, establish the current commercial baseline, assess the vendor's likely position and leverage, and develop a strategy from there. Prior involvement helps but is not a prerequisite.
How does the outcomes-based fee work in practice?
Before work begins, we agree on a commercial baseline — the vendor's current or opening commercial position. At the conclusion of the negotiation, a savings calculation is prepared against that baseline. The methodology for calculating savings is agreed upon up front and independently verified by a third party, separate from both Wilverley and the client's negotiating team. Our outcomes fee is applied to the verified savings figure. The full mechanics are set out in the engagement letter before any work starts.
You advise vendors on their FS negotiations. Are you conflicted?
We never advise both sides of the same transaction. If any vendor in your negotiation is a current Wilverley client on a related sell-side engagement, we will tell you immediately and manage the conflict before proceeding. Our conflict policy is systematic and available in full on request. In practice, the intelligence our sell-side work gives us is what makes our buy-side negotiation advisory significantly more effective than a buy-side-only advisor — but only if that intelligence is deployed cleanly and without conflict.
