The SLA is not what was actually broken
I wrote a marketing-to-sales SLA in my first year running growth at a seed-stage company, and it barely moved anything. Response times stayed the same. Sales kept calling the leads garbage in Slack. The document sat in Notion, unopened, three weeks after we agreed on it.
That's not a bad-execution story, it's the default outcome. Seventy-three percent of B2B companies have no documented SLA between marketing and sales, so "go write one" is the advice you hear everywhere. But only 8 percent of B2B companies have a documented, shared definition of what actually makes a lead qualified. Handing two teams a clean response-time table doesn't survive contact with a rep who doesn't believe the leads in it are real.
What the SLA measures, and what it can't
An SLA measures speed. It can't measure agreement. Eighty-two percent of C-level executives at B2B companies believe their marketing and sales teams are aligned. Only 35 percent of the people actually doing the work, the reps taking the calls, the marketers building the campaigns, say the same thing. That 47-point gap isn't a communication problem you close with a faster response window. It's a definitions-and-incentives problem wearing a communication-problem costume, and handoffs broken this way destroy over a trillion dollars of B2B revenue a year globally.
Three gaps that break the handoff before the SLA gets tested
Before I write another SLA for a client or my own team, I check three things first, because writing the document before fixing these is exactly why the last one didn't work.
- Definition gap. "Qualified" means two different things when each team invents its own definition in isolation. If your marketer counts a whitepaper download as qualified and your rep expects someone ready to discuss pricing, every handoff becomes a renegotiation, no matter what response window the SLA promises.
- Incentive gap. Marketing is usually paid on volume: leads generated, MQLs delivered, pipeline sourced. Sales is paid on closed revenue. A response-time target doesn't touch either incentive, so when the two teams disagree about a lead, each side keeps optimizing for a number the SLA never mentions.
- Feedback loop gap. Sales marks a lead "junk" and moves on. Marketing never sees why. Without that loop, marketing keeps generating the same low-quality volume the SLA is measuring the response time to, and the SLA quietly becomes a stopwatch on a problem nobody is actually fixing.
Fix the gaps, then write the SLA, not the reverse
Close the definition gap first, in one sitting: pull ten leads sales called good and ten they called bad, and find the three data points that actually separated them. That becomes your qualification checklist, written by both teams together, not handed from one to the other.
Close the incentive gap by adding one shared number both teams are measured on, something like leads that reach a second call, not just volume for marketing or closed revenue for sales. A single shared metric does more for alignment than a five-page playbook.
Close the feedback loop by making disposition reasons mandatory in the CRM, and reviewing the top three reasons together every two weeks, not quarterly. Fifteen minutes every two weeks catches drift before it becomes a trend line marketing didn't know existed.
Only once those three are moving do you write the response-time SLA. At that point it isn't creating alignment, it's documenting alignment that already exists, which is the only version of an SLA that survives past the second month.
What to do this week
Skip the SLA draft for now. Pull ten good and ten bad leads from the last month, get someone from sales in a room for twenty minutes, and build the qualification checklist together. Put one shared metric on both teams' dashboards. Make disposition notes mandatory starting Monday. Write the SLA in week three, not week one.
Frequently asked questions
Does a marketing-sales SLA actually help at all?
Yes, but only after the underlying agreement exists. An SLA formalizes a shared understanding into a number; it can't create the understanding itself.
What should I fix before writing an SLA?
Start with a shared, written definition of what counts as a qualified lead. Most misalignment traces back to marketing and sales quietly using different definitions.
How do I know if my problem is definitions or incentives?
Ask five people on each team, separately, what makes a lead qualified. If you get five different answers, it's a definition gap. If everyone agrees on the definition but still argues about priority, it's an incentive gap.
How long does it take to fix these gaps?
The definition and feedback-loop fixes can happen in a single week with the right people in the room. The incentive fix usually takes longer since it touches comp plans, but a temporary shared metric can bridge the gap in the meantime.
Is this only a problem for bigger sales teams?
No, it shows up faster at small teams, since one misqualified lead is a much bigger share of a two- or three-person pipeline than it is at a fifty-person org.
