Glossary. The terms that matter.

Commercial goal

An outcome a procurement team wants, stated in its own words, such as saving $1M on indirect spend by March or moving suppliers from Net 45 to Net 60. In Whispor, every piece of work starts from a commercial goal, and the goal is what the plan and the outcome are measured against.

Commercial Intelligence

What a system knows about an organization's commercial world: spend, contracts, suppliers, the market, negotiation history and outcomes, read together. In Whispor it supplies the data behind every forecast in a plan. Negotiation Intelligence is the part of it that learns how each supplier negotiates.

Plan approval

The step between a plan and any action on it. A Whispor plan splits a goal into what Whispor does, what the team does and what is left alone, and nothing in it starts until a person approves it.

Autonomy level

How far an AI agent may go without asking. Whispor uses three: ask me every time, send inside my limits, and run it to the close. Strategic suppliers are always led by a person regardless of the level.

Finalist negotiation

Negotiating one to one with the best respondents after a sourcing event closes, instead of awarding on the sealed bids. Distinct from a reverse auction, where suppliers bid against a live price board.

Negotiation practice

Rehearsing a real negotiation against an AI playing the supplier, scored against the same target and limit the buyer will use on the call. In Whispor this is the Prepare & Train capability.

Outcome review

A written comparison, after a negotiation, of what the plan forecast, what was agreed and what was paid, with proposed changes for the next negotiation. In Whispor, proposed changes apply only after approval, and only to new negotiations.

Negotiation Intelligence

The capability layer that decides where negotiating is worth the effort, supports or runs the negotiation itself, and keeps what the organization learned for the next one. Distinct from spend analytics, which reports what was bought, and from sourcing software, which orchestrates the event around the negotiation. Negotiation Intelligence acts on the negotiation and on the counterparty, and it compounds, because positions, concessions and rate history from one deal inform the next. Whispor builds Negotiation Intelligence on Behavioral AI.

AI negotiation platform

Software that performs, or guides a human to perform, supplier negotiation using machine learning, large language models, game theory, or behavioral models. Distinct from classic sourcing software in that it acts on the negotiation itself (generating offers, choosing concessions, guiding counter-moves) rather than merely orchestrating an RFx or managing contracts.

Autonomous negotiation

An AI agent conducting supplier negotiation end-to-end inside defined guardrails, with no human in the loop per turn. The human sets the mandate and the bounds; the agent handles the conversation. Examples include Whispor's Autonomous Negotiation, Pactum, Zycus Merlin ANA, and Keelvar's sourcing bots.

Assisted negotiation

An AI layer that sits alongside a human negotiator during pre-brief, live call, and debrief (surfacing counterparty context, walk-away points, and real-time tactical guidance) while the human remains the decision-maker. Whispor's Assisted Negotiation is purpose-built for this role.

Tail spend

The long tail of supplier spend (typically the 80% of suppliers that represent 20% of spend) that is too numerous for procurement teams to negotiate individually. Historically ignored or touched only by exception, the tail is the natural home of autonomous negotiation agents.

Strategic spend

High-value supplier relationships and contracts where outcomes depend on human judgment, relationship management, and multi-variable trade-offs across price, term, payment terms, SLA, and volume. Strategic deals reward assisted negotiation more than autonomy.

One-time, no-login portal

A negotiation surface for suppliers that requires no account, no install, and no registration, accessed through a single-use link sent via branded email. Whispor's Autonomous Negotiation and Pactum both use this pattern. Contrast with bid-event platforms that require supplier portal registration.

Counterparty memory

Structured institutional memory of prior interactions with a specific supplier (prior concessions, disclosed constraints, pricing history, behavioral patterns) used to inform subsequent negotiations. In Whispor, the same counterparty memory serves every capability, from Sourcing to Assisted and Autonomous Negotiation.

Deal desk

The pricing and approval function inside a supplier's sales organization that decides, in advance, what an account manager may concede, in what order, and in exchange for what. Deal desks operate through price floors, discount approval matrices, and playbooks; the account manager on a call is the interface to that system, not the final authority. Most enterprise suppliers run one; most procurement teams negotiate without an equivalent.

Guardrails

Declarative constraints that define what an AI negotiation agent may and may not offer or concede. Guardrails replace imperative scripts with bounds the agent must respect, letting the agent choose tactics within those bounds rather than following a fixed sequence.

Contract-space model

A formal representation of the set of acceptable outcomes for a negotiation, across all relevant levers: price, term, payment terms, SLA, volume tiers, exclusivity, termination clauses, and so on. Treating the contract space as a multi-dimensional object, not a single price, is what lets an AI agent trade across levers rather than only haggle on price.

Locked mandate

A pre-negotiation commitment by the buyer's organization to the walk-away point, zone of possible agreement, and acceptable trade-offs, fixed before the call begins and protected from in-room improvisation. The mandate is the single biggest predictor of negotiated outcome; locking it is the single biggest lever procurement teams under-use.

Walk-away point

The worst-acceptable outcome at which a negotiator will terminate rather than accept the counterparty's offer. For the buyer, the lower bound of the agreement zone. An un-committed walk-away point is a walk-away point that will be crossed.

Zone of possible agreement (ZOPA)

The overlap between the buyer's and seller's reservation points, the range within which any mutually acceptable deal must lie. If the buyer's walk-away is £100k and the seller's walk-away is £120k, the ZOPA is empty and no deal exists. If the buyer's walk-away is £130k and the seller's is £110k, the ZOPA is the £110k–£130k band and the negotiation is about how that surplus is divided.

Source-to-pay (S2P)

The end-to-end procurement software category spanning sourcing, contracts, purchasing, invoicing, and payment. Major S2P suites include SAP Ariba, Coupa, Oracle Procurement Cloud, Ivalua, and GEP SMART. An "S2P-agnostic" tool is one that plugs into any of these rather than requiring a specific suite.

Best-of-breed

A procurement software philosophy that prefers specialist tools stitched together by API over a single end-to-end suite. Trades integration effort for sharper capability in each layer. The opposite philosophy is single-suite procurement.

Rate card drift

The gap between the negotiated rate on a rate card and the effective price the buyer actually pays over time. Drift accumulates through three mechanisms: off-card exceptions (items priced outside the card), volume shortfalls (actual spend falling below the volume that underwrote the rate), and unchecked index adjustments (contractual escalation clauses applied without buyer verification). The compound effect can move effective rates 8–15% from the negotiated baseline inside a single contract year.

Predictive sourcing

A category of sourcing platform (Arkestro is the canonical example) that uses machine learning to predict target prices for a commodity or category and behavioral-science nudges to steer supplier bids toward those targets across multi-round events. Predictive sourcing is AI-guided rather than autonomous: the buyer runs the event, the platform predicts and nudges.
