What This Is

A vendor is any external provider you pay to do something you don't have the team, time, or expertise to do yourself. This playbook turns "I guess they're doing a good job" into a measurable system: onboarding, performance scoring, renewal decisions, and the monthly vendor meeting that catches hidden costs before they become emergencies.

Key Components

Core Framework

Step 1: Tier Your Vendors (1 Hour)

Not all vendors are equal. The critical ones deserve separate treatment. A tier system keeps you from over-managing the trivial and under-managing the important.

Critical Vendor

Definition: Eliminating this vendor for even a week creates a business-critical outage or revenue loss.

Examples: Hosting provider, core payment processor, key SaaS platform Management frequency: Weekly

High Vendor

Definition: Their failure creates a measurable disruption but the business can survive short-term. High opportunity cost.

Examples: Customer support vendor, marketing agency, warehouse space Management frequency: Bi-weekly

Moderate Vendor

Definition: Failure creates some inconvenience but business continues.

Examples: Office cleaning, graphic designer, IT managed services Management frequency: Monthly

Low Vendor

Definition: Failure is annoying but not critical. Maintenance only.

Examples: Coffee service, office supplies, miscellaneous subscriptions Management frequency: Quarterly

Step 2: The Vendor Onboarding Checklist (90 Minutes)

A bad vendor onboarding process is the #1 source of vendor disasters. You don't know what you don't know until something goes wrong.

Commercial check: Contract signed, payment terms, renewal dates
Access check: Non-disclosure agreement (NDA) signed, rights granted
Technical check: Credentials, SLA guarantees, uptime commitments
Security check: SOC 2 report reviewed, penetration testing history
On-call check: Who to call in an emergency, escalation path
Reporting check: Monthly reporting template agreed, delivery frequency
Offboarding check: Cancellation process documented, data portability clause
Timeline: Schedule the first follow-up meeting (14 days)

Step 3: Vendor Performance Scoring (Monthly)

Assign a score (1-10) to each metric. Average the scores for a vendor's monthly score. Use this score for renewal decisions and to escalate underperforming vendors.

Performance Scorecard by Tier

Metric Weight Target (10) Critical
Uptime/Availability 35% 99.9% Yes
Response Time 20% 4 hours Yes
Quality 15% 85% No
Cost Control 15% Within budget No
Compliance 15% 100% Yes
Scoring rule: If a metric hits 7 or below, flag it. If the average is below 7, initiate a performance improvement plan.

Step 4: The Monthly Vendor Meeting (30 Minutes)

A 30-minute meeting with every vendor you pay more than $1,000/month. No fluff. Just the five questions that expose hidden costs and performance gaps.

The Five Questions

  1. What did we get this month that we didn't expect? Look for unexpected value, new features, or unadvertised services.
  2. What's broken and when will it be fixed? Don't ask vague questions. Demand dates.
  3. What costs more than last month and why? Rate increases, unused add-ons, hidden fees. Force transparency.
  4. What have you delivered that wasn't billed? Extra support, bug fixes, training. Ask for it next month.
  5. Is there anything we should have asked that we didn't? This is how you find new things the vendor won't tell you voluntarily.

Step 5: The Quarterly Review (2 Hours)

Compare the actual scores to the target scores. Make a renewal decision. If you're letting a high-tier vendor go, give them 60 days notice and start the onboarding process for a replacement.

Quarterly Review Agenda

Question Action Item
What was the actual score vs. target? Calculate and flag gaps
Is renewal still justified? Yes/No + timeline
What changed since last quarter? Document for next review
What did we learn? Update onboarding checklist

Worked Example

The $150,000 Mistake

A SaaS vendor was delivering at 98% uptime (target 99.9%). The company didn't flag it because they were "happy with the service." When the vendor increased prices by 25% six months later, the team realized they had been overpaying for a service they didn't realize they were getting only 98% of.

The fix: Monthly vendor meeting exposed the uptime gap. A 1.9% difference looks small until you multiply it by $60,000 in annual spend. The company renegotiated, installed a competitor during the contract term, and reduced costs by 18%.

Next Steps

Immediate Actions (Next 2 Weeks)

  1. Score all vendors in your system (create a spreadsheet if you don't have one)
  2. Assign tiers based on the tiering framework
  3. Schedule the first monthly vendor meeting with your top 10 vendors by spend
  4. Download the SLA template to upgrade the 3 worst contracts
Common Pitfall: Thinking vendors will tell you when they're underperforming. They won't. The monthly meeting is the only way to catch gaps before they become exits.
