Vendor Management Skill for Claude

Vendor Management

Covers the vendor lifecycle from selection to exit. Two failures dominate this

discipline: tiering vendors by spend rather than by blast radius, and losing

every point of renewal leverage to a missed notice deadline. This skill is built

around preventing both.

When to use this skill

• Selecting a vendor and needing a scorecard that survives scrutiny
• A renewal is approaching and the notice deadline needs to be found before it passes
• Reviewing the vendor portfolio for concentration, risk tier coverage, and consolidation
• Preparing a business review with SLA performance and credits owed
• A vendor is underperforming and the case needs to be built on trend, not anecdote
• Planning an exit and needing the sequence right

Inputs the skill expects

• For selection: weighted criteria, must-have requirements, and 0-10 scores per vendor with evidence
• For the portfolio: annual spend, category, renewal date, notice days, and auto-renew flag per vendor
• Risk inputs per vendor: data classification, business criticality, alternative availability, subprocessor use
• Internal owner per contract
• For SLA reporting: committed metrics with target, actual, direction, credit tiers, and prior-period history
• Annual contract value and the contractual credit cap

Clarify First

Before generating, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• [ ] Is the notice deadline known, or only the renewal date? — the notice deadline is what constrains action, and missing it removes all leverage for a full term
• [ ] Were the scoring weights set before any vendor was scored? — weights chosen after seeing candidates produce a justification, not a decision
• [ ] What does this vendor actually hold or touch? — data sensitivity and criticality drive the risk tier; spend does not
• [ ] Which must-haves are genuinely pass/fail? — every entry on that list eliminates a candidate, so preferences belong in the weighted criteria

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Workflows

Workflow 1 — Select a vendor

• Agree weighted criteria and the must-have list before looking at any candidate. Record who agreed them and when.
• Define anchors for each criterion — what a 10 looks like and what a 5 looks like. This is what stops the scorecard becoming post-hoc justification.
• Score each candidate against evidence (demo, reference call, document reviewed), not impression. Note the evidence in the scorecard.
• Run the scorer and read the stability check before the ranking. A margin under 5% is a tie — decide it on commercial terms, exit cost, or reference calls instead.
• If the result flips when a weight moves 50%, take that criterion back to the decision owner before proceeding.

Workflow 2 — Review the portfolio

• Build the vendor list with renewal date, notice days, and auto-renew flag. The notice deadline is derived, and it is the date that matters.
• Set as_of explicitly so the analysis is reproducible and reviewable later.
• Run the analyser and work the urgent renewals first — anything marked LOCKED has already lost its negotiating window for this term.
• Check concentration in both forms: single-vendor share above 25-30% is a dependency, and category HHI tells you whether you have leverage or diversification.
• Treat every unowned contract as a future auto-renewal. Assign an owner before anything else in the report.

Workflow 3 — Run an SLA review

• Collect committed metrics with target, actual, direction, and credit tiers. Include prior periods — the trend is the argument.
• Run the report and check credits earned against the contractual cap. Credits exceeding the cap mean the remedy structure is too weak to change behaviour.
• Claim the credits. Unclaimed credits are the norm, and most contracts require you to ask.
• Escalate severe breaches to the contract owner, not the account manager — the account manager cannot change the terms that caused it.
• Carry the findings into the renewal ask: credit tiers that bite, and a termination right after repeated breach.

Decision frameworks

Risk tiering [PROVEN]

Score data sensitivity plus business criticality, then apply modifiers.

| Data classification | Points | | Business criticality | Points |

|--------------------|--------|---|---------------------|--------|

| PHI / health | 4 | | Critical (revenue stops in hours) | 4 |

| PII | 3 | | High (core function stops in a day) | 3 |

| Financial | 3 | | Medium (productivity loss) | 2 |

| Confidential | 2 | | Low (inconvenience) | 1 |

| Internal | 1 | | | |

| Public | 0 | | | |

Modifiers: no ready alternative +2 · network access to your systems +2 ·

subprocessors +1 · non-adequate jurisdiction +1 · vendor under 20 people +1.

| Total | Tier | Core obligations |

|-------|------|------------------|

| 8+ | Tier 1 critical | Annual security review, quarterly business review, tested exit plan, SLA with credits |

| 6-7 | Tier 2 high | Full questionnaire at onboarding, semi-annual review, documented exit plan |

| 4-5 | Tier 3 moderate | Short-form questionnaire, annual review, verified data export |

| Under 4 | Tier 4 low | Confirm what data it touches; nothing further |

Tier by blast radius, not spend. The $8K tool holding your entire customer

list outranks the $400K hosting contract holding nothing sensitive.

Where renewal leverage comes from [PROVEN]

| Source | Worth | Requires |

|--------|-------|----------|

| A real alternative | 10-30% | 3-6 weeks of genuine evaluation, an internal sponsor willing to switch |

| Vendor fiscal timing | 10-25% | Knowing their year-end and aligning your close to it |

| Multi-year commitment | 10-20% | Price protection, exit-on-SLA-failure, and an increase cap — all three |

| Volume / consolidation | 15-30% | Real growth, not aspirational seat counts |

| Reference or case study | 5-15% | Marketing time, not money |

| Annual prepay | 5-10% | Cash-flow float, and a viability check first |

Not leverage: complaining about price, threatening to leave without an

alternative, escalating without a specific ask, or loyalty — long tenure lowers

vendor risk, which is why tenured accounts are often priced higher.

Renewal calendar [PROVEN]

| Days before renewal | Action |

|--------------------|--------|

| 180 | Usage vs entitlement; confirm owner; decide renew / renegotiate / exit |

| 150 | Open the alternative evaluation if renegotiating seriously |

| 120 | First vendor conversation — signal expectations before they build the quote |

| 90 | Notice deadline on most annual contracts. Serve notice if there is any doubt. |

| 60 | Negotiate substance: price, increase cap, true-down, SLA credits, exit rights |

| 30 | Close; anything open now resolves in the vendor's favour |

Serving notice is not leaving — it converts an auto-renewal into a negotiation.

Terms worth more than price [RECOMMENDED]

| Term | Target |

|------|--------|

| Annual increase cap | CPI, or 3-5% maximum |

| Seat true-down rights | At renewal, without penalty |

| Termination for SLA failure | Defined breach threshold, no penalty |

| Data export format | Open, documented, and tested |

| Subprocessor change notice | 30 days with an objection right |

| Assignment on acquisition | Consent required, or an exit right |

Seat true-down is the most valuable and least-requested term: nearly every SaaS

contract lets you add seats mid-term and forbids reducing them.

Anti-Patterns

Tiering by spend

Mistake: Applying diligence proportional to contract value — heavy scrutiny on the big infrastructure contract, a credit card and no questions for the $8,000 tool.

Why it happens: Procurement owns the process and procurement thresholds are denominated in money. Approval workflows trigger on spend because that is what finance systems can see.

Instead: Tier on data sensitivity and business criticality, with modifiers for substitutability and subprocessors. The small tool holding your customer list has a far larger blast radius than the large contract holding nothing sensitive, and it is exactly the one that gets bought on a card without a security review.

Discovering the notice deadline after it passes

Mistake: Tracking renewal dates only, then finding at day 60 that the 90-day notice window closed a month ago and the contract has auto-renewed for another year.

Why it happens: Renewal dates are what contracts and calendars display. The notice deadline is a derived date nobody computes, and auto-renew clauses are written to be easy to miss.

Instead: Track both dates per contract, and treat the notice deadline as the real one. Serve notice at the deadline as routine on anything you intend to renegotiate — it reopens the contract without committing you to leave. An unowned contract is the one this happens to, so assign an internal owner to every vendor.

The scorecard that ratifies a decision already made

Mistake: Choosing the vendor, then building a weighted scorecard whose weights and scores produce that vendor as the winner.

Why it happens: Rarely cynical. Someone forms a view during the demos, and weights get set afterwards with that view in the room — each individual weight feels defensible while the set of them is not.

Instead: Set and record the weights, with named anchors for what a 10 and a 5 look like, before any candidate is scored. Then run the sensitivity check: if the winner changes when one weight moves 50%, the result is an artifact of the weighting rather than a finding about the vendors, and the decision owner needs to see that before signing.

Treating the SLA as a control

Mistake: Accepting a 99.9% uptime commitment with a 2% service credit and considering the risk managed.

Why it happens: The SLA exists, it has numbers in it, and it satisfies the checklist item. Nobody computes what the credit is actually worth against what an outage costs.

Instead: Price the remedy. A 2% credit on a $20K quarter is $400 for an outage that may cost you far more — that is a rounding error the vendor has already priced in, not a control. Negotiate tiered credits (5/10/25%), a cap above 20% of period fees, and a termination right after repeated breach. Losing the account changes vendor behaviour; credits do not. And measure availability against the error budget, not the percentage — missing 99.9% by half a point is nearly six times the permitted downtime.
