End the Lead-Quality Blame Game with a Sales–Marketing SLA

Every company with a sales and a marketing team eventually has the same argument. Marketing says it is delivering plenty of qualified leads. Sales says the leads are junk. Both are partly right, and the argument never ends — because there is no shared definition of what a qualified lead even is.

What an SLA fixes

A Sales–Marketing SLA (service-level agreement) replaces opinion with agreement. It does three things: defines each stage of a lead the same way for both teams, sets a clear handoff process, and commits both sides to mutual standards on volume, quality and speed. Once it exists, lead quality stops being a matter of opinion and becomes a number you both watch.

Start with shared definitions

The foundation is a shared vocabulary. A Lead is any captured contact. An MQL meets agreed fit and engagement criteria. A SAL is a lead Sales has reviewed and accepted. An SQL has confirmed need, budget and timeline. Write the qualifying criteria down together — fit, engagement signals, and disqualifiers — so a lead only advances when it genuinely meets the bar.

Commit to speed-to-lead

Response time is the single biggest lever on conversion, and the one teams most often ignore. Set times you will actually honour: first contact on a new MQL within 30 minutes in business hours, a minimum number of follow-up attempts over a set window, and a rule for returning leads that do not qualify.

Review one scorecard

Finally, both teams should look at the same numbers on a set cadence: MQL volume, MQL-to-SQL rate, speed-to-lead, win rate and revenue sourced from marketing. Weekly on flow, monthly on the scorecard, quarterly on the agreement itself. The template above gives you all of it ready to fill in.

The bottom line

The blame game ends the moment both teams agree what good looks like and watch the same scorecard. Put it in writing, review it on a cadence, and marketing and sales finally pull in the same direction.
