What is SLA (Service Level Agreement)?
A service level agreement (SLA) is a formal agreement between two parties — often marketing and sales, or a company and its customers — defining specific performance standards, responsibilities, and accountability metrics.

What is an SLA (Service Level Agreement)?
An SLA is a documented agreement that defines what each party commits to delivering — with measurable standards, timelines, and consequences for falling short.
In marketing, SLAs most commonly refer to the agreement between marketing and sales teams. Marketing commits to delivering X qualified leads per month. Sales commits to following up within Y hours. Both sides have clear, measurable accountability. HubSpot’s research shows that companies with marketing-sales SLAs achieve 34% greater revenue than those without them.
SLAs also exist between companies and customers (uptime guarantees, response time commitments) and between businesses and vendors. The internal marketing-sales SLA is the one that most directly impacts revenue growth.
Why Does an SLA Matter?
Without an SLA, marketing blames sales for not closing leads and sales blames marketing for sending bad leads. The finger-pointing never ends because there’s no shared definition of success.
- Alignment — Both teams agree on what a qualified lead looks like, how many are needed, and how fast they’ll be worked
- Accountability — Measurable commitments replace vague expectations. If marketing promises 200 MQLs and delivers 130, that’s a visible miss
- Revenue predictability — Known lead volumes + known follow-up rates = predictable pipeline generation
- Reduced friction — Clear agreements eliminate the most common source of marketing-sales conflict
The SLA is the single most impactful document for fixing broken marketing-sales alignment.
How an SLA Works
A good marketing-sales SLA covers three areas.
Marketing’s Commitments
Marketing defines how many leads they’ll deliver monthly, at what quality level, and through which channels. Example: “Marketing will deliver 250 MQLs per month with a minimum lead score of 50 and verified contact information.” The definition of MQL must be agreed upon by both teams.
Sales’ Commitments
Sales defines how they’ll handle those leads. Example: “Sales will contact every MQL within 4 business hours, make a minimum of 5 follow-up attempts over 14 days, and update the CRM disposition within 24 hours of each attempt.” This prevents leads from sitting untouched.
Shared Definitions
Both teams must agree on terminology. What exactly is an MQL? What makes it a sales qualified lead? At what point does a lead get recycled back to marketing? These definitions prevent 90% of the “your leads are bad” vs. “you’re not following up” arguments.
Review Cadence
Meet monthly to review SLA performance. Marketing shows lead volume and quality trends. Sales shows follow-up compliance and conversion rates. Adjust targets quarterly based on actual data — not assumptions.
SLA Examples
Example 1: B2B SaaS marketing-sales alignment A SaaS company establishes: Marketing delivers 300 MQLs/month (defined as: visited pricing page, company size 10-500, submitted a form). Sales contacts each MQL within 2 hours, attempts 6 touches over 10 days. Result: pipeline from inbound increases 45% in the first quarter because leads get worked faster and more consistently.
Example 2: Agency-client SLA A digital marketing agency’s SLA with clients guarantees: monthly reporting by the 5th of each month, 24-hour response to client emails, and minimum organic traffic growth of 10% quarterly. theStacc operates on a similar model — publishing 30 SEO articles monthly with measurable organic traffic impact, giving clients clear expectations and accountability.
Common Mistakes to Avoid
Most businesses make the same handful of errors. Recognizing them saves months of wasted effort.
Chasing tactics without strategy. Jumping on every new channel or trend without a clear plan. TikTok one month, LinkedIn the next, podcasts after that — none done well enough to produce results. Pick your channels based on where your audience actually spends time, not what’s trending on marketing Twitter.
Measuring the wrong things. Tracking impressions and likes instead of conversion rate and revenue. Vanity metrics feel good in reports. They don’t pay the bills.
Ignoring existing customers. Most marketing teams focus 90% of their energy on acquisition and 10% on retention. The math says that’s backwards — acquiring a new customer costs 5-7x more than keeping one.
Key Metrics to Track
| Metric | What It Measures | Good Benchmark |
|---|---|---|
| Customer Acquisition Cost (CAC) | Total cost to acquire one customer | Varies by industry — lower is better |
| Customer Lifetime Value (CLV) | Revenue from a customer over time | Should be 3x+ your CAC |
| Conversion Rate | % of visitors who take desired action | 2-5% for websites, 15-25% for email |
| Return on Investment (ROI) | Revenue generated vs money spent | 5:1 is a common benchmark |
| Click-Through Rate (CTR) | % of people who click after seeing | 2-5% for ads, 3-10% for email |
Quick Comparison
| Aspect | Basic Approach | Advanced Approach |
|---|---|---|
| Strategy | Ad hoc, reactive | Planned, data-driven |
| Measurement | Vanity metrics (likes, views) | Business metrics (revenue, CAC, LTV) |
| Tools | Spreadsheets, manual tracking | Marketing automation, CRM integration |
| Timeline | Short-term campaigns | Long-term compounding strategy |
| Team | One person does everything | Specialized roles or automated workflows |
Frequently Asked Questions
What should a marketing-sales SLA include?
At minimum: lead volume targets, lead quality definitions, follow-up timing requirements, CRM update expectations, and a monthly review cadence. Add escalation procedures for when either side falls short of commitments.
How often should we update the SLA?
Review performance monthly. Update the SLA terms quarterly based on what the data shows. If marketing consistently over-delivers and sales can’t keep up, either increase sales capacity or reduce lead volume targets. The SLA should reflect reality, not wishful thinking.
What if one side consistently misses their SLA?
Address it immediately in the monthly review. Chronic misses mean either the targets are unrealistic or there’s a resourcing problem. Adjust targets downward if needed, or invest in the capacity to hit them. An SLA that nobody meets is worse than no SLA at all.
