I found out our lead handoff was broken by accident. A prospect who had downloaded two guides, attended a webinar, and visited our pricing page three times told me, almost apologetically, that nobody from our team had ever followed up. She had been sitting in our CRM as a marketing qualified lead for eleven days.
That is not a fluke. It is the default state of most early-stage B2B SaaS companies, because most of them never wrote down what happens the moment a lead crosses from marketing's job to sales's job.
What actually breaks in the handoff
Seventy-three percent of B2B companies have no documented service-level agreement between marketing and sales. That single gap is why an estimated 53 percent of qualified leads die before a rep ever picks up the phone. The lead did the work of raising a hand. Nobody on the other side had a job description that said catch it.
The failure is almost never a single dramatic mistake. It is five small gaps stacking on top of each other:
- No written SLA, so nobody owns the outcome when a lead goes cold.
- MQL and SQL definitions that live in someone's head instead of a shared doc, so marketing and sales are grading the same lead on different scales.
- Manual routing, meaning a lead sits in an inbox or a spreadsheet until someone remembers to look.
- Context that gets stripped in the transfer, so the rep opens the record cold instead of knowing what the person actually read, clicked, or asked.
- No feedback loop back to marketing, so a bad lead source keeps getting funded because nobody ever reports which leads actually closed.
The SLA to write this week
You do not need a RevOps hire or a marketing automation platform to fix this. You need one shared document, agreed by whoever runs marketing and whoever runs sales, even if that is the same two founders wearing both hats. It has four parts.
- A shared MQL definition, in writing, combining fit and behavior. Fit is job title, company size, and industry. Behavior is a specific action, like requesting a demo or visiting the pricing page twice in a week, not a vague 'showed interest.'
- A shared SQL definition that sales has to actively agree to, not one marketing hands them. If sales can reject a lead, they need documented criteria for why, so the rejection becomes data instead of an argument.
- A response-time commitment from sales, in writing, and a routing commitment from marketing. A two-hour first-touch window on high-intent leads is a strong early-stage target; anything past 24 hours and the lead has usually moved on to a competitor or lost the urgency that made them qualify in the first place.
- A weekly feedback loop, ten minutes, where sales reports back which handed-off leads actually converted and which were mis-qualified, so the MQL definition gets sharper instead of staying frozen from the day someone first wrote it.
Why the definitions matter more than the software
Only 8 percent of B2B companies have shared, documented MQL and SQL definitions. Everyone else is routing leads on gut feel, which means the same lead can look qualified to the person who generated it and unqualified to the person who has to call it. That mismatch is measurable: average MQL-to-SQL conversion across B2B sits around 13 percent, while teams running a documented, behavior-based qualification model convert closer to 39 to 40 percent. That gap is not a talent gap. It is a definitions gap.
If you are still working out where the MQL and SQL lines actually sit for a team without a dedicated sales function yet, start with the underlying framework before you formalize the handoff itself. The SLA only works once both sides agree on what they are handing off.
What this looked like once we fixed it
After the eleven-day lead, we wrote a one-page SLA in an afternoon. MQL: director-level or above, 50 to 500 employees, plus a demo request or two pricing-page visits in seven days. SQL: sales confirms budget authority and a stated timeline on the first call. Response commitment: two business hours for any lead that requested a demo, same day for everything else. Feedback loop: fifteen minutes every Friday.
Nothing about our product or our marketing spend changed that week. The only thing that changed was that a lead could no longer sit unclaimed. Within a month, the Friday feedback call had already killed one lead source that looked great in a dashboard and closed nobody, and doubled down on a smaller one that was quietly converting at three times the rate.
The 30-day move to make first
Pull the last 20 leads that were marked qualified. Count how many got a first response within two hours, and how many are still sitting untouched. That number, not a benchmark from a company ten times your size, is the actual case for writing the SLA. Then write the one-page version above, get both sides to sign it, and put the Friday feedback call on the calendar before you do anything else.
Frequently asked questions
What is a marketing-to-sales SLA?
A written agreement between marketing and sales that defines what counts as a qualified lead, how fast sales commits to following up, and how routing and feedback work between the two teams.
Do we need a CRM or automation platform to do this?
No. A shared document and a calendar reminder for a weekly feedback call cover most of the value. Automation helps once lead volume is high enough that manual routing becomes the bottleneck, not before.
How fast should sales respond to a qualified lead?
Within two business hours for high-intent leads like demo requests. Response time is one of the strongest predictors of whether a lead converts, and it decays fast after the first day.
What is a good MQL-to-SQL conversion rate?
Around 13 percent is the broad B2B average. Teams with a documented, behavior-based qualification model and a real feedback loop report conversion closer to 39 to 40 percent.
Who should own the SLA, marketing or sales?
Neither, alone. It has to be co-owned, because the moment one side writes it unilaterally, the other side treats it as someone else's rulebook instead of a shared commitment.
A lead handoff SLA is one page, takes an afternoon to write, and stops the most expensive kind of leak a startup has: paying to generate a lead and then losing it to silence. See how we help early-stage founders build a repeatable lead process before scaling spend on top of a broken one.
