# Service Level Agreement (SLA)

Agreement defining expected service standards and response times.

[Back to glossary](/sales/glossary/)

## What is a Service Level Agreement (SLA)?

A Service Level Agreement (SLA) is a formal contract that defines the level of service expected from a provider, including specific metrics, responsibilities, and remedies if service standards aren't met.

In sales and customer success contexts, SLAs typically define:  
* Response times to leads and customers
* Resolution times for issues
* Uptime and availability guarantees
* Performance benchmarks

---

## Why SLAs Matter

### For Sales and Marketing Alignment

**Marketing SLA (MQL to SQL):**  
\-承诺: Marketing delivers 500 qualified leads monthly  
\-承诺: Sales responds within 5 minutes during business hours  
\-承诺: Sales works leads for 14 days before disqualification

**Benefits:**  
* Creates accountability for lead quality and follow-up
* Prevents finger-pointing when targets are missed
* Aligns teams around shared revenue goals

### For Customer Success

**Customer Support SLA:**  
\-承诺: Response within 2 hours for critical issues  
\-承诺: Resolution within 24 hours for high-priority tickets  
\-承诺: 99.9% uptime for software services

**Benefits:**  
* Sets clear customer expectations
* Creates metrics for team performance
* Provides recourse if service falls short

---

## Types of SLAs

### 1\. Customer-Based SLA

**Definition:**  
Specific service commitments for individual customers or customer segments.

**Examples:**  
* Enterprise customers: 1-hour response, 99.99% uptime
* SMB customers: 4-hour response, 99.9% uptime
* Free tier: 24-hour response, best-effort uptime

### 2\. Service-Based SLA

**Definition:**  
Standard service commitments for all customers using a particular service.

**Examples:**  
* All software users: 99.5% uptime guarantee
* All support customers: Initial response within 24 hours
* All email customers: Delivery within 5 minutes

### 3\. Multilevel SLA

**Definition:**  
Different service levels based on issue severity or customer tier.

**Example Severity Levels:**

| Level    | Description                     | Response Time | Resolution Time |
| -------- | ------------------------------- | ------------- | --------------- |
| Critical | System down, production blocked | 15 minutes    | 4 hours         |
| High     | Major feature broken            | 1 hour        | 8 hours         |
| Medium   | Workaround available            | 4 hours       | 24 hours        |
| Low      | Minor issue                     | 24 hours      | 72 hours        |

---

## Key SLA Metrics

### Response Time

**Definition:**  
Time between customer contact and initial human response.

**Benchmarks:**  
* **Critical issues:** 15-30 minutes
* **High priority:** 1-2 hours
* **Standard requests:** 4-24 hours

### Resolution Time

**Definition:**  
Time between issue reported and problem fully resolved.

**Benchmarks:**  
* **Critical issues:** 4-8 hours
* **High priority:** 24 hours
* **Standard requests:** 3-5 business days

### Uptime/Availability

**Definition:**  
Percentage of time service is operational.

**Common Standards:**  
* **99.9% uptime ("three nines"):** 8.76 hours downtime/year
* **99.99% uptime ("four nines"):** 52.56 minutes downtime/year
* **99.999% uptime ("five nines"):** 5.26 minutes downtime/year

### First Contact Resolution (FCR)

**Definition:**  
Percentage of issues resolved on first contact without follow-up.

**Benchmark:**  
* **Good:** 70-80%
* **Industry average:** 60-70%

## Creating Effective SLAs

### 1\. Be Specific and Measurable

**Good SLA:**  
"We will respond to all critical support tickets within 30 minutes, 24/7/365"

**Poor SLA:**  
"We'll respond to critical issues as soon as possible"

### 2\. Set Realistic Expectations

**Consider:**  
* Current team capacity and capabilities
* Peak volume periods
* Technical constraints
* Budget limitations
**Risk of Over-Promising:**  
* Damaged reputation when missed
* Financial penalties
* Customer churn

### 3\. Include Exclusions

**Common Exclusions:**  
* Scheduled maintenance windows
* Customer-caused issues
* Third-party service failures
* Force majeure events
* Free or trial tiers

### 4\. Define Remedies

**When SLAs Are Missed:**  
* Service credits (percentage of monthly fee)
* Extended contracts at no cost
* Penalty payments (less common)
* Root cause analysis and improvement plan

## Common SLA Mistakes

1. **Vague Language** \- "Reasonable effort" vs specific timeframes
2. **No Measurement** \- Can't prove compliance without tracking
3. **One-Size-Fits-All** \- Same SLA for all customer segments
4. **Ignoring Capacity** \- Setting targets team can't achieve
5. **No Exclusions** \- Not accounting for maintenance or third-party failures
6. **Forgetting Growth** \- Not updating SLAs as business scales
7. **No Penalties** \- SLAs without teeth are just promises
