Marketing and Sales SLA: How to Agree on Lead Standards

Marketing says it sent 200 leads last month. Sales says it got nothing worth calling. Both are looking at the same CRM, and both are sure the other team is the problem. You have probably sat in that meeting.

The fix is rarely a new tool or a bigger budget. It is a written agreement on what counts as a real lead, how fast it gets worked, and what happens when it does not convert. That agreement is a service level agreement, an SLA, between the two teams. It turns a recurring argument into a set of numbers you can check.

This piece walks through how to build one: what to put in it, how to set the numbers, and how to keep it alive after the kickoff meeting where everyone nods and then forgets.

What a marketing and sales SLA actually covers

An SLA between marketing and sales is a two-way contract. Marketing commits to a volume and quality of leads. Sales commits to working those leads inside a defined window and logging the outcome. Each side holds up its end because the other side is watching the same dashboard.

Most useful SLAs answer four questions:

• What is a qualified lead? The exact criteria a lead must meet before sales is expected to call.
• How many? The monthly volume marketing commits to, often split by lead grade.
• How fast? The time sales has to make first contact after a lead arrives.
• Then what? The number of follow-up attempts, the disqualification rules, and how rejected leads flow back to marketing.

Get those four right and most of the finger-pointing disappears. The lead either met the criteria or it did not. Sales either called inside the window or it did not. The record is in the CRM.

Step 1: Define the qualified lead together

This is where the whole thing lives or dies. If marketing and sales hold different pictures of a good lead, no SLA will save you.

Start by separating fit from intent. Fit is whether the company looks like your buyer: industry, company size, region, budget authority. Intent is whether the person is showing buying behavior: requested a demo, downloaded a pricing sheet, replied to a sequence. A strong lead usually needs both. A CFO at your ideal company who downloaded a top-of-funnel checklist has fit without much intent yet.

Write the criteria as a checklist, not a vibe. A condensed example (numbers and fields are illustrative):

Criterion	Minimum to pass to sales
Company size	25+ employees
Region	US, UK, Canada, Australia
Role	Manager level or above
Action taken	Demo request, pricing view, or reply to outreach
Disqualifiers	Student, competitor, personal email only

The point is that both teams sign off on this table. When sales says "this lead was junk," you can check it against the row. If it passed every criterion and still felt weak, your criteria need work, and that is a marketing-plus-sales conversation, not a blame session. Getting the definitions right is the same discipline behind any solid lead qualification process, and the SLA is where you write it down.

If you already grade leads as MQL and SQL, the SLA is where you nail down what separates the two, and what each team owes the other once a lead crosses that line.

Step 2: Set the volume commitment

Marketing's side of the contract is usually a monthly number of qualified leads. The temptation is to pick a round figure that sounds good in a board deck. Resist it.

Work backward from revenue instead. If sales needs 10 new deals a month and your historical lead-to-deal rate is 5%, you need roughly 200 qualified leads. If marketing can realistically deliver 120 at current spend, you have found a gap before it becomes a crisis, and you can talk about budget or about raising conversion rather than discovering the shortfall in week three.

Tie the commitment to grades if your leads vary a lot in quality. A simple split:

• A leads (fit plus strong intent): marketing commits to 40 per month, sales commits to a 1-hour response.
• B leads (fit, lighter intent): 80 per month, same-day response.
• C leads (intent, weaker fit): no volume commitment, nurtured by marketing until they qualify.

This stops the gaming that kills trust. When the only metric is total leads, marketing has every reason to push borderline contacts across the line to hit the number. Grade-based commitments reward the right behavior.

Step 3: Lock in the response time

Speed is the part of the SLA with the clearest payoff. The longer a lead sits, the colder it gets, and the drop-off is steep in the first hour. We dug into the evidence and the mechanics in lead response time, but the headline for the SLA is simple: define a maximum time to first contact, by lead grade, in writing.

A workable structure:

• A leads: first contact within 1 hour during business hours.
• B leads: same business day.
• C leads: within 48 hours or held for nurture.

Two details people forget. First, define "first contact." A logged call attempt counts; a CRM status change does not. Second, decide what happens after hours and on weekends. A lead that arrives Friday at 6pm should not silently blow the SLA by Monday morning, so set business-hours windows or assign weekend coverage.

Here is the flow the SLA is protecting, from arrival to a logged outcome:

Step 4: Define follow-up and the feedback loop

First contact is not the finish line. Plenty of good leads need five or six touches before they pick up. So the SLA should also set a minimum number of follow-up attempts before a lead can be marked dead. Three to six touches across a week or two is a common range, spread over calls and email.

The other half of this step is the return path. When sales rejects a lead, marketing needs to know why, in a structured field rather than a vent. Build a short list of disqualification reasons: wrong fit, no budget, bad timing, bad contact data, already a customer. Each reason tells marketing something different. A pile of "bad data" points at your forms. A pile of "no budget" points at your targeting.

That feedback is what makes the SLA improve over time. Sales rejections flow back, marketing tightens criteria or targeting, lead quality rises, and the argument about low-quality leads gets quieter each quarter. Without the loop, the SLA is a one-time document. With it, it is a tuning instrument.

Step 5: Pick the metrics and where they live

An SLA you cannot measure is a wish. Decide upfront which numbers you track and which system holds them. For most teams that is the CRM plus a shared dashboard both leaders look at weekly.

The core scorecard:

• Marketing side: qualified leads delivered vs committed, by grade.
• Sales side: percentage of leads contacted inside the window, average time to first contact, average follow-up attempts.
• Shared: lead-to-deal rate by grade, and rejection reasons by category.

Keep it to numbers both sides agreed to before the month started. The whole value of an SLA is that nobody can relitigate the rules after seeing the results. If marketing missed volume, that is on the dashboard. If sales let A leads sit for a day, that is there too. This kind of shared accountability is the practical core of real sales and marketing alignment, and the SLA is the document that makes it concrete.

Common mistakes when writing the SLA

Writing it alone. If marketing drafts the SLA and emails it to sales for sign-off, sales did not agree to anything, they got assigned homework. Build it in a room together.

Too many criteria. A 14-point qualification checklist feels rigorous and kills your volume. Start with the four or five criteria that actually predict a deal and add more only when the data justifies it.

No enforcement. An SLA with no review cadence is a poster on the wall. Put a standing 30-minute monthly meeting on the calendar where both leaders look at the same scorecard.

Treating it as permanent. Your first numbers are guesses. The 5% conversion rate, the 1-hour window, the volume target: revisit them after a quarter of real data and adjust. The agreement should get sharper as you learn.

FAQ

What is a marketing and sales SLA?

A written agreement where marketing commits to delivering a set number of qualified leads at an agreed quality, and sales commits to contacting and following up on those leads within defined time windows. It also defines how rejected leads flow back to marketing.

How is an SLA different from lead scoring?

Lead scoring is the method you use to rank and grade leads. The SLA is the contract built on top of that grading: it says how many leads of each grade marketing will deliver and how fast sales will work them. Scoring tells you which leads are good; the SLA tells you what each team does about them.

What response time should we commit to?

It depends on your leads, but the principle holds across B2B: faster is better and the first hour matters most. A common structure is one hour for your highest-grade leads during business hours, same-day for mid-grade, and a longer window or nurture for low-intent leads. Set the exact numbers from your own data and your team's capacity.

Who should own the SLA?

Both team leaders own it jointly, since neither side can deliver alone. In practice one person, often in revenue operations or marketing operations, maintains the dashboard and runs the monthly review, but accountability for the numbers sits with the marketing and sales leaders together.

How often should we review it?

Monthly for the operational scorecard, quarterly for the targets themselves. The monthly review catches missed windows and volume gaps while they are still fixable. The quarterly review is where you adjust the conversion assumptions, the volume commitment, and the response windows based on a real sample of data.

What if marketing keeps hitting volume but sales says the leads are weak?

That is a definition problem, and it is exactly what the SLA exists to surface. Pull the rejection reasons from the CRM. If leads are technically passing every criterion but still converting poorly, the criteria are too loose and need tightening together. If sales is rejecting leads that clearly fit, the conversation moves to follow-up effort. Either way, the data decides, not the loudest voice.

Wrapping up

A marketing and sales SLA is not bureaucracy. It is the cheapest way to stop losing good leads to a process gap nobody owns. Pin down five things and you have most of the value:

• A qualified lead defined as a checklist both teams signed.
• A monthly volume commitment tied back to revenue, ideally by grade.
• A maximum response time per grade, with "first contact" defined.
• A minimum follow-up count and a structured rejection-reason loop.
• A shared dashboard and a standing monthly review.
