Marketing SLAs: How to Write One with Sales and Freelancers

Geometric illustration of shared responsibilities in an SLA

A marketing SLA (service level agreement) is a short document that sets out who does what, by when, and to what standard. Within a company, it is especially useful in two areas: between marketing and sales, to establish how many leads are needed, what makes a good lead, and how quickly someone should follow up; and between a company and outside professionals, to define deliverables, response times, revision rounds, and what happens when something goes off track. This guide covers both, with a sample calculation, a metrics table, an escalation process you can adapt, and the clauses that matter in an NDA with a freelancer.

TL;DR

  • An SLA turns vague promises (“we’ll send you more leads,” “we’ll call them right away”) into measurable commitments, with an owner and a deadline.
  • For marketing and sales, start with the revenue target and work backward to the number of qualified leads needed each month.
  • The trickiest part is lead response time: it must reflect the sales team’s actual capacity, not wishful thinking.
  • With freelancers, the SLA defines deliverables, response times, revisions, and reporting; the NDA protects information without preventing the professional from doing their work.
  • Without an escalation process, an SLA is just a document nobody opens.

What an SLA is and why it matters for marketing

The concept originated in IT services, but the structure works anywhere. The AgID guidelines on PDND interoperability describe an SLA as an agreement between a service provider and a service recipient, built on two levels: Service Level Indicators (SLIs), which measure the service, and Service Level Objectives (SLOs), which define the targets to reach. The same document identifies the elements of a good agreement: the parties involved, the term, scope, objectives, penalties, and exclusions.

In marketing terms:

  • SLI: average time between a lead entering the CRM and the first sales contact.
  • SLO: 90% of qualified leads contacted within 24 business hours.
  • Scope: inbound leads from the website and campaigns only, excluding trade shows and events.
  • Exclusions: company-wide vacations, technical issues with the CRM.
  • Consequences: not fines between colleagues, but a clear escalation process (more on that later).

Unlike a contract with a vendor, an SLA between departments is not legally binding: it works because it was written together, is visible to everyone, and is reviewed regularly.

SLA, KPI, SLO: three different things

This is the question we hear most often, and the confusion is costly: teams end up calling a KPI dashboard an SLA, even though nobody has committed to meeting its targets.

Term What it is Marketing example Who is accountable
KPI A measure of business performance Customer acquisition cost, conversion rate The department responsible for it
SLA A mutual commitment between two parties Marketing delivers 25 MQLs per month; sales contacts them within 24 hours Both parties signing the agreement
SLO The numerical target within the SLA 90% of leads contacted within 24 hours The party that made the commitment
SLI The measurement used to check the SLO Average hours from lead arrival to first contact Whoever manages the data (often marketing ops)

In short: a KPI tells you how you’re doing; an SLA says who needs to do what to help you succeed.

The SLA between marketing and sales

This is the most searched-for use case—and the most useful. In the HubSpot Skill Up podcast episode on sales and marketing SLAs, the logic is simple: marketing commits to a certain quantity and quality of leads, and sales commits to working those leads within a defined timeframe. The episode also emphasizes that the hardest part isn’t the metrics, but sales reps’ response time, which needs to be negotiated based on actual operating capacity.

Why does timing matter so much? A study of more than two million leads published in Harvard Business Review in 2011, reviewed and analyzed by Rework, found that companies attempting contact within an hour were nearly seven times more likely to qualify the lead than those that waited longer. An SLA that says “follow up within 72 hours” because nobody wanted to discuss it is effectively throwing away part of the media budget.

How to build one in six steps

  1. Start with the revenue target. Not the number of leads marketing thinks it can generate, but how much revenue the company needs to bring in during the period.
  2. Define MQLs and SQLs together. An MQL (marketing qualified lead) is a contact that meets agreed-upon criteria: industry, company size, role, and action taken. An SQL (sales qualified lead) is an MQL that sales has vetted and accepted. If only one department writes the definitions, the SLA is already on shaky ground.
  3. Calculate how many leads you need. Use historical conversion rates, even approximate ones, and work backward from closed deals to leads (see the example below).
  4. Set lead response times. Define the first contact, number of attempts, and window for accepting or rejecting a lead. Ask the sales team how many hours they actually have available, not how many they wish they had.
  5. Build in a feedback loop. Every rejected lead goes back to marketing with a reason selected from a fixed list (“outside target market,” “no budget,” “incorrect contact”). That’s the data that improves campaigns.
  6. Set a review cadence. A monthly check of the numbers and a quarterly review of the definitions are enough for most small and midsize businesses.

A worked example

A B2B services company has an annual target of €600,000 in new revenue and an average contract value of €20,000. That means it needs 30 new customers.

  • If sales closes 25% of SQLs, it needs 120 SQLs per year.
  • If 40% of MQLs become SQLs, it needs 300 MQLs per year.
  • Spread across twelve months: 25 MQLs per month.

The SLA becomes: marketing delivers at least 25 MQLs per month based on the agreed definition; sales contacts every MQL within one business day, makes at least three attempts in five days, and accepts or rejects it with a reason within ten days. These rates are hypothetical: replace them with your own, even if you only have data from the last six months.

The metrics to put in writing

Area Indicator Sample threshold Owner
Volume MQLs delivered per month ≥ 25 Marketing
Quality Share of MQLs accepted by sales ≥ 40% Marketing
Speed Time from lead arrival to first contact Within 1 business day Sales
Persistence Contact attempts per lead At least 3 in 5 days Sales
Clarity Rejected leads with a stated reason 100% Sales
Data Required CRM fields completed 100% Both

Escalation policy: what happens when the SLA isn’t met

An SLA without consequences is wishful thinking. But those consequences shouldn’t turn into a trial: the marketing SLA template from Craft emphasizes shifting from blame to shared accountability. A three-level process works in most cases:

  1. Level 1: automatic alert. A lead that hasn’t been contacted after 24 hours triggers a notification to the assigned sales rep and sales manager. No meeting, just visibility.
  2. Level 2: weekly check-in. If missed targets exceed an agreed threshold (for example, 20% of leads not contacted on time that week), the two department heads have a fifteen-minute conversation and decide on an action: reassign leads, pause a campaign, or revise MQL criteria.
  3. Level 3: agreement review. If the SLA is missed for two months in a row, the problem isn’t the people—it’s the agreement: the numbers are wrong, or the capacity isn’t there. Rewrite the SLA with leadership.

The same framework applies to an external provider: an alert, a discussion between the points of contact, then a review of the contract or scope.

SLAs with freelancers and external teams

When part of your marketing is outsourced, the SLA shifts from a relationship between departments to one between a company and a professional. Here, it also carries contractual weight and is the simplest way to avoid arguments over “when” and “how much” once a project is underway. If you’re considering this route, we’ve explained when outsourcing marketing makes sense and how to make it work.

What to define:

Item What to specify Example
Deliverables What, in what format, and by when 8 posts per month, source files included, by the 25th of the previous month
Response times How quickly messages receive a response, and during which hours Within 1 business day, 9 a.m.–6 p.m., Monday through Friday
Revisions How many rounds are included and their turnaround times 2 rounds, feedback within 3 days, changes within 2
Approval Who approves and what happens if there is no response One point of contact; after 5 days without a response, the deliverable is considered accepted
Reporting What is measured and how often Monthly report with agreed-upon metrics
Delays What happens if either party misses a deadline Rescheduling in writing; delayed feedback shifts deadlines

Two things to keep in mind. The SLA works both ways: if the company supplies materials late, the freelancer’s deadlines shift. And a good SLA starts with a good brief: without clear objectives, delivery timelines are meaningless. That’s why it helps to start with a structured creative brief and checklist, then include the SLA in a freelance contract designed to protect both parties.

A practical caution: an SLA with an independent professional defines outcomes and deadlines, not attendance requirements or working methods. If you find yourself wanting to impose fixed hours or office attendance, have an employment advisor review the classification of the working relationship before you sign.

NDAs with freelancers: the clauses that matter

A nondisclosure agreement almost always accompanies the SLA because the freelancer has access to sales data, launch plans, and strategies. As this guide to nondisclosure agreements for businesses explains, an NDA serves two purposes: it limits how shared information can be used and formalizes the commitment not to disclose it to third parties.

What you need to include:

  • A precise definition of confidential information. “Everything related to the company” is too vague to be useful in a dispute.
  • Permitted use. The information may be used only for the specified project.
  • Duration of the obligation, including after the engagement ends.
  • Return or destruction of materials at the end of the project.

And what to avoid. According to this guide to NDAs for freelancers and consultants, an NDA should not become a noncompete agreement in disguise: it needs an exception for portfolio use (agreeing on what can be shown and when) and one for general skills and methods, which the professional must be free to reuse. The same guide suggests responding to an overly restrictive agreement with a revised version: if the client rejects reasonable requests, that’s a warning sign worth taking seriously.

If the project involves customers’ personal data, confidentiality alone isn’t enough: data processing must also be governed in accordance with the GDPR. When truly sensitive information is involved—patents, confidential price lists, corporate transactions—have a lawyer with expertise in business contracts review the agreement.

Automating response-time monitoring

An SLA monitored manually in a spreadsheet that gets updated whenever someone remembers won’t last more than a few weeks. The handoff from marketing to sales should be managed in the CRM: automatic assignment, a timer starting when the lead arrives, notifications at each escalation level, and rejection reasons in a dropdown menu.

CRM lead assignment timer and escalation flow

Italian businesses are moving in this direction. In the 2025 ISTAT report on businesses and ICT, marketing and sales are the business function where artificial intelligence is most widely adopted (33.1%). Beyond the CRM, companies looking to go a step further can use custom AI agents to monitor tasks and deadlines, helping send reminders when someone is late, summarize lead status, or prepare the weekly report. We’ve covered what’s really changing in this space in our guide to AI for marketing in 2026.

One rule holds true regardless of the tool: automate measurement and alerts, not decisions. Deciding whether a lead is a good fit or an SLA needs rewriting is still a job for people.

Mistakes that undermine an SLA

  • Writing it alone. An SLA imposed by marketing on sales, or vice versa, will be ignored at the first difficult week.
  • Too many metrics. Once you go beyond six or seven indicators, people stop looking at them. Keep the ones in the table and add only what you’ll actually use.
  • Ambiguous definitions. “Hot lead” is not a definition. “A company with 20–200 employees that has requested a demo” is.
  • No baseline data. If you don’t know how long it currently takes to follow up with a lead, measure it for a month before setting a threshold.
  • Never reviewing it. Markets, products, and teams change; the SLA needs to keep up.
  • Forgetting external collaborators. If a freelancer manages half your campaigns, they also need to know the internal SLA and the timelines it creates.

Our perspective

Every day, we work with companies and startups that bring external marketing, design, content, and digital development professionals into their teams. What we see is that an SLA rarely fails because of the numbers: it fails when the people expected to meet it haven’t been carefully selected and brought together. A brilliant freelancer who doesn’t connect with the sales team will deliver perfect materials at the wrong time.

That’s why, even before the document, we focus on two things. The first is selection: we look beyond technical skills to fit with the company’s culture and pace. The second is management: when professionals work as a coordinated team with a single point of contact, the company can focus on strategy instead of chasing deadlines one by one. At that point, the SLA stops being a list of penalties and becomes what it should be: a clear agreement between people working toward the same result.

Frequently asked questions

What does SLA mean in business?

SLA stands for service level agreement. It is a document that sets measurable commitments between two parties: a provider and a client, or two departments within the same company. It specifies what is guaranteed, which indicators are used to measure it, and what happens if the targets aren’t met.

What’s the difference between a KPI and an SLA?

A KPI measures a result, such as conversion rate or customer acquisition cost. An SLA is a mutual commitment that uses specific indicators to verify that each party is doing its part. You can have many KPIs without any SLA, but every SLA relies on clearly defined indicators.

Should a freelancer sign an NDA before seeing the brief?

It’s a common and reasonable practice when the brief contains confidential information. The NDA should be proportionate, though: limited to genuinely sensitive information, with a defined duration and no clauses that prevent the professional from working in their field. If the agreement is highly restrictive, asking for changes is normal.

How often should a marketing SLA be reviewed?

Check the numbers every month, and review definitions, thresholds, and scope quarterly. An additional review is needed when the product, pricing, sales team size, or acquisition channels change. If the SLA is missed for two consecutive months, it needs to be rewritten—not just brought up again.
