Sales Efficiency
Sales efficiency measures how effectively your sales and marketing investment converts into new revenue. It encompasses multiple metrics — magic number, CAC payback, quota attainment, and pipeline conversion rates — that together describe how much revenue each dollar of sales investment produces.
Why Sales Efficiency Matters for SaaS Companies
Sales efficiency determines whether scaling your sales team will accelerate growth or just burn more cash. If each sales rep generates $500K in new ARR against $200K in fully-loaded cost, adding reps is a great investment. If that ratio is inverted, more reps means more burn. For Seed to Series B companies preparing to scale, sales efficiency is the prerequisite for sustainable growth investment.
An Operator's Take
I think of sales efficiency as the question that comes before 'should we hire more reps?' If efficiency is low, more reps amplify the problem. Fix the process first. At one engagement, sales efficiency was terrible — $1.80 in S&M spend for every $1 of new ARR. The problem was not the reps. It was that 40% of their time was spent on manual CRM data entry, quote generation, and contract processing. We automated those workflows and reps spent 60% more time selling. Efficiency went from 0.55 to 0.9 without changing headcount.
Common Mistakes
What I see go wrong at Seed to Series B companies.
Measuring sales efficiency only by revenue per rep. Include all sales and marketing costs — tools, marketing spend, support during sales cycle.
Assuming low efficiency means reps are underperforming. Often the issue is process friction, poor lead quality, or inadequate tools.
Scaling headcount before optimizing efficiency. Adding reps to an inefficient process makes the problem bigger, not better.

Frequently Asked Questions
What is a good sales efficiency ratio?
A ratio above 1.0 means each dollar of S&M spend generates more than a dollar of new ARR — this is the minimum target. Above 0.75 is acceptable for growth-stage companies. Below 0.5 signals significant efficiency problems that should be addressed before increasing investment.
