Series B companies face a unique challenge in their sales operations. They've proven product-market fit but now need to build scalable revenue engines that can support rapid growth. The wrong metrics can waste precious time and resources during this critical phase.

Series B sales teams need specific KPIs that balance growth velocity with efficiency, focusing on metrics like customer acquisition cost, sales cycle length, and pipeline conversion rates that directly impact their path to profitability. Unlike earlier-stage startups, Series B companies must prove they can scale sustainably while maintaining healthy unit economics.

I've seen too many Series B teams get distracted by vanity metrics instead of focusing on the key performance indicators that actually drive revenue. The KPIs you choose now will determine whether your sales team becomes a growth engine or a resource drain as you scale toward your next funding round.

Key Takeaways

• Series B sales teams must track KPIs that prove scalable growth rather than just activity metrics
• Pipeline conversion rates and customer acquisition costs are more important than total lead volume at this stage
• The right sales KPIs help balance rapid growth with the efficiency investors expect from maturing companies

Core KPIs for Series B Sales Teams

Series B sales teams need specific metrics that reflect their growth stage focus on scaling revenue predictably. The most critical measurements center on consistent revenue expansion, deal closure efficiency, individual performance against targets, and transaction value optimization.

Revenue Growth and ARR

Annual recurring revenue stands as the foundation metric for Series B companies. I track both month-over-month and year-over-year ARR growth to understand momentum patterns. The target growth rate typically ranges from 100-200% annually at this stage.

Total revenue measurements include both new customer acquisition and expansion revenue from existing accounts. I monitor new ARR separately from expansion ARR to identify which growth engine drives performance.

Key ARR Metrics:

• Net new ARR per month
• ARR growth rate (monthly and annual)
• Expansion ARR percentage
• ARR churn rate

Revenue growth consistency matters more than sporadic spikes. I look for steady monthly increases that compound over time rather than unpredictable revenue patterns that make forecasting difficult.

Closed Deals and Win Rate

Win rate reveals sales team effectiveness at converting qualified opportunities into customers. Most effective sales teams track between 4-10 KPIs with win rate as a core foundation metric.

I calculate win rate by dividing closed-won deals by total closed deals (won plus lost). Industry benchmarks vary, but Series B SaaS companies typically target 20-25% win rates for new business.

Deal velocity impacts cash flow and growth projections. I measure average sales cycle length from first contact to signed contract. Shorter cycles indicate product-market fit strength and sales process efficiency.

Win Rate Analysis:

• Overall team win rate
• Individual rep win rates
• Win rate by deal size
• Win rate by lead source

Tracking closed deals by rep helps identify top performers and coaching opportunities for struggling team members.

Quota Attainment

Individual quota attainment shows whether reps meet their assigned targets. I track this monthly and quarterly to spot performance trends early. Strong Series B teams achieve 70-80% quota attainment across all reps.

Team quota attainment measures collective performance against company revenue goals. This metric directly impacts investor confidence and future funding rounds.

I monitor quota attainment distribution to understand team health:

Consistent underperformance indicates hiring issues, training gaps, or unrealistic targets. I adjust quotas based on market conditions and historical performance data.

Average Deal Size

Average deal size directly impacts revenue growth efficiency. Sales teams should track deal size as a key performance indicator alongside other revenue metrics.

I calculate this by dividing total revenue by number of closed deals over a specific period. Growing average deal size reduces the number of customers needed to hit revenue targets.

Deal size trends reveal market positioning effectiveness. Increasing averages suggest successful upmarket movement, while declining sizes may indicate competitive pressure or pricing issues.

I segment deal size analysis by:

• New customers vs. existing customer expansions
• Sales rep performance
• Product line or package type
• Customer segment or industry

Tracking deal size distribution prevents over-reliance on a few large deals that create unpredictable revenue patterns.

Sales Pipeline and Conversion Metrics

I track these metrics to measure how effectively my Series B sales team moves prospects through our funnel and converts leads into revenue. Pipeline coverage ratios and lead conversion rates directly impact my ability to hit growth targets and scale predictably.

Lead Generation and Opportunities Created

I measure lead generation effectiveness by tracking the number of qualified opportunities my team creates each month. For Series B companies, I typically see successful teams generating 3-5 qualified opportunities per sales rep monthly.

Key metrics I monitor include:

• Monthly qualified leads generated
• Lead-to-opportunity conversion rate (usually 15-25%)
• Source attribution for highest-converting channels
• Time from lead capture to qualification

I focus heavily on lead quality over quantity. My team tracks which lead sources produce the highest conversion rates and longest customer lifetime values. Marketing-qualified leads should convert to sales-qualified opportunities at consistent rates.

The lead response time significantly impacts conversion success. I require my reps to respond to inbound leads within 5 minutes during business hours. This aggressive response time increases our connection rates by 60% compared to waiting an hour.

Conversion Rate and Sales Funnel

My sales funnel conversion rates tell me exactly where prospects drop off and which stages need improvement. I track conversion rates between each stage of our sales process.

Critical conversion metrics I analyze:

I calculate our overall lead conversion rate by dividing closed deals by total leads generated. For Series B companies, I aim for a 3-6% lead-to-close conversion rate depending on deal size and complexity.

Sales cycle length directly impacts conversion rates. I track average days in each funnel stage and identify bottlenecks. Opportunities stalled beyond our average timeline have 50% lower close rates.

Pipeline Coverage and Forecast Accuracy

I maintain pipeline coverage of 3-4x my quarterly revenue target to account for deal slippage and natural attrition. This coverage ratio ensures I hit my numbers even when 25-30% of forecasted deals push to the next quarter.

My forecast accuracy improves when I track essential pipeline metrics consistently. I measure forecast accuracy by comparing predicted revenue to actual closed revenue each quarter. Accurate forecasting requires at least 80% precision at the 90-day mark.

Pipeline health indicators I monitor weekly:

• Total pipeline value vs. coverage target
• Weighted pipeline based on stage probability
• Deal velocity and progression rates
• Win rate by deal size and source

I review pipeline coverage monthly and adjust lead generation accordingly. When coverage drops below 3x, I increase marketing spend and prospecting activities. Sales pipeline metrics tracking on a daily basis helps me make informed decisions about resource allocation and team performance.

Sales Efficiency and Activity KPIs

I track activity-based metrics to measure how efficiently my sales reps convert their daily efforts into revenue. These KPIs reveal whether my team's calling cadence, meeting frequency, and deal progression align with our growth targets.

Sales Activities and Productivity

I measure the volume and quality of daily sales activities to understand my team's productivity patterns. Key sales activities include calls made, emails sent, meetings booked, and demos completed per rep.

My most critical activity metrics include:

• Calls per day: I track 40-60 outbound calls per rep daily
• Email open rates: I aim for 25-30% open rates on prospecting sequences
• Meeting conversion: I measure how many calls convert to qualified meetings
• Activity-to-opportunity ratio: I calculate how many activities generate each new opportunity

I use activity data to identify top performers and coach struggling reps. High-activity reps who generate few opportunities need better targeting or messaging. Low-activity reps may need motivation or process improvements.

The close ratio metric helps me understand which activities drive the best results. I compare activity levels across my team to set realistic benchmarks and quotas.

Sales Cycle Length

I monitor average sales cycle length to predict revenue timing and identify bottlenecks in my sales process. My Series B company typically sees cycles between 30-90 days depending on deal size.

Key cycle metrics I track:

I break down sales cycle data by rep, deal size, and customer segment. Enterprise deals naturally take longer than mid-market opportunities. New reps often have longer cycles while they learn our methodology.

When I notice cycle length increasing, I investigate common sticking points. Long cycles often indicate pricing objections, missing decision makers, or unclear next steps. I work with reps to identify and remove these obstacles.

Sales Calls and Touchpoints

I analyze call frequency and quality to optimize my team's outreach strategy. The number of touchpoints needed to convert prospects varies by market segment and buying committee size.

My call performance metrics include:

• Dial-to-connect ratio: I expect 8-12% connection rates for cold calls
• Call duration: Qualified conversations average 8-15 minutes
• Follow-up frequency: I track touchpoints per prospect over time
• Call outcome tracking: I categorize each call as qualified, not interested, or follow-up needed

I review call recordings to identify coaching opportunities and successful talk tracks. Sales teams that track touchpoints typically see higher conversion rates than those using random outreach patterns.

Data shows most prospects need 6-8 touchpoints before responding. I ensure my reps maintain consistent follow-up without becoming pushy or aggressive.

Customer Retention and Expansion KPIs

I track retention rate to measure how well my sales team keeps existing customers, while customer lifetime value shows me the long-term revenue potential of each client. My team focuses on upselling and cross-selling metrics to drive expansion revenue from our current customer base.

Retention Rate and Churn Rate

I calculate my customer retention rate by dividing the number of customers at the end of a period by the number at the start, then multiplying by 100. For Series B companies, I aim for retention rates above 90% annually.

My customer churn rate is the flip side of retention. I track it monthly and quarterly to spot trends early. A churn rate below 5% monthly is strong for B2B SaaS companies.

I break down churn by customer segments to find patterns. Enterprise customers typically have lower churn than small businesses. I also track voluntary churn (customers who leave by choice) separately from involuntary churn (failed payments).

Key retention metrics I monitor:

• Monthly recurring revenue (MRR) churn rate
• Customer count churn rate
• Cohort retention analysis
• Time to churn after onboarding

Customer Lifetime Value (CLV)

I calculate CLV by multiplying average revenue per customer by gross margin percentage, then dividing by churn rate. This tells me how much revenue I can expect from each customer relationship over time.

For my Series B sales team, I track CLV trends by customer segment and acquisition channel. I want to see CLV growing as we improve our customer relationship management and reduce churn.

I compare CLV to customer acquisition cost (CAC) to ensure profitable growth. My target is a CLV to CAC ratio of at least 3:1. Higher ratios indicate more efficient sales and marketing spend.

CLV components I track:

• Average contract value
• Contract length
• Renewal rates by segment
• Expansion revenue per customer

Upselling, Cross-Selling, and Referrals

I measure upselling success by tracking the percentage of existing customers who increase their spend. My team targets at least 20% of customers for upselling opportunities each quarter.

Cross-selling metrics show how well I expand into new product lines or services. I track the number of products per customer and revenue from additional offerings. Multi-product customers typically have higher retention rates and lower churn.

Referrals from happy customers are highly valuable leads. I track referral volume, conversion rates, and the CLV of referred customers. Referred customers often have 25% higher retention rates than other acquisition channels.

Expansion metrics I monitor:

• Net revenue retention (NRR) above 110%
• Upsell conversion rate by customer segment
• Cross-sell attach rates
• Referral program participation and results

Sales Efficiency and Financial Health Metrics

These metrics reveal how efficiently your Series B sales team converts investment into revenue growth. They measure the true cost of acquiring customers and the sustainable revenue patterns that drive long-term business value.

Customer Acquisition Cost (CAC)

Customer acquisition cost (CAC) measures the total expense of gaining one new customer. I calculate this by dividing all sales and marketing costs by the number of customers acquired in that period.

For Series B companies, CAC typically ranges from $200 to $15,000 depending on your industry. B2B software companies often see CAC between $1,000-$5,000 per customer.

Here's how I break down CAC calculation:

• Sales team salaries and commissions
• Marketing campaign costs
• Software tools and technology
• Content creation and advertising

I track CAC monthly to spot trends early. If CAC rises faster than customer lifetime value, it signals efficiency problems. Sales KPIs that align with business objectives help identify these issues before they impact growth.

The CAC payback period matters too. I aim for 12-18 months maximum. Longer periods strain cash flow and indicate poor sales efficiency.

Monthly Recurring Revenue (MRR) and Recurring Revenue

Monthly recurring revenue (MRR) tracks predictable revenue from subscriptions and contracts. This metric shows business stability and growth trajectory.

I calculate MRR by adding all recurring subscription revenue normalized to monthly amounts. Annual contracts get divided by 12. One-time payments don't count toward MRR.

Key MRR components include:

• New customer MRR
• Expansion MRR from upgrades
• Churned MRR from lost customers
• Net MRR growth rate

Series B companies should target 15-25% monthly MRR growth. I track this alongside B2B sales KPIs that focus on conversions and efficiency to understand revenue quality.

Recurring revenue provides cash flow predictability. It helps forecast future performance and makes your company more attractive to investors. I monitor MRR trends to spot seasonal patterns and growth opportunities.

Average Purchase Value

Average purchase value measures the typical amount customers spend per transaction. I calculate this by dividing total revenue by the number of sales transactions.

This metric reveals customer spending patterns and pricing strategy effectiveness. Higher average purchase values indicate successful upselling or premium positioning.

I track average purchase value across different segments:

Increasing average purchase value costs less than acquiring new customers. I focus on bundling products, offering premium tiers, and training sales teams on value-based selling.

When sales metrics measure performance against strategic goals, average purchase value becomes a powerful lever for revenue growth without proportional increases in acquisition costs.

Tools, Enablement, and Sales Operations

Effective CRM systems and data management form the backbone of Series B sales performance tracking. Sales operations teams must focus on building predictable revenue streams through strategic enablement programs that equip managers with actionable insights.

CRM and Data Management

Your CRM platform becomes the single source of truth for tracking Series B KPIs. Salesforce and HubSpot dominate this space because they offer robust reporting capabilities that Series B companies need.

I recommend configuring your CRM to automatically capture pipeline velocity, deal progression, and rep performance metrics. Clean data entry standards are non-negotiable at this stage. Poor data quality will skew your KPIs and lead to bad business decisions.

Key CRM configurations include:

• Custom fields for deal qualification scores
• Automated stage progression workflows
• Revenue forecasting dashboards
• Activity tracking for sales rep accountability

Your CRM should calculate metrics like average deal size, win rates by rep, and time-to-close automatically. Manual reporting wastes valuable time that sales managers need for coaching and strategy.

Sales Operations and Sales Enablement

Sales operations teams must build systems that support consistent performance measurement. Sales enablement KPIs directly impact your ability to scale revenue predictably.

I focus on three core enablement areas: content utilization, training effectiveness, and tool adoption. Track which sales materials generate the highest close rates. Measure how quickly new hires reach full productivity after onboarding.

Content performance metrics include:

• Usage rates by sales stage
• Win rates when specific materials are used
• Time saved per deal cycle

Sales operations should also monitor technology stack efficiency. If reps spend too much time switching between tools, productivity drops. Integration between your CRM, email platform, and sales engagement tools is essential.

Sales Strategy and Predictable Revenue

Building predictable revenue requires strategic KPI alignment across your entire sales organization. I measure both leading indicators like pipeline generation and lagging indicators like closed revenue.

Pipeline coverage ratios become critical at Series B stage. You need 3-4x pipeline coverage to hit quarterly targets consistently. Track this metric weekly, not monthly.

Sales managers need real-time visibility into:

• Individual rep performance against quota
• Deal slippage patterns by product line
• Customer acquisition cost trends
• Monthly recurring revenue growth rates

Your sales strategy should include specific playbooks for different deal sizes and customer segments. Measure conversion rates at each stage of these playbooks. This data helps you identify where reps need additional coaching or where your process needs refinement.

Frequently Asked Questions

Series B sales teams face unique challenges when selecting and implementing KPIs that support rapid scaling while maintaining sustainable growth metrics. The following questions address common concerns about measurement frameworks, target setting, and performance tracking during this critical growth phase.

What are the top KPIs to measure sales team performance in a Series B company?

I recommend focusing on key performance indicators that drive revenue and support scaling objectives. Monthly recurring revenue (MRR) growth rate stands as the most critical metric for Series B companies.

Customer acquisition cost (CAC) and customer lifetime value (LTV) ratio should maintain a 3:1 minimum ratio. I track sales cycle length to ensure deals close efficiently as the team grows.

Lead conversion rates across each funnel stage help identify bottlenecks. Pipeline velocity measures how quickly opportunities move through sales stages.

Rep productivity metrics include quota attainment percentage and average deal size. I monitor these monthly to spot performance trends early.

How can a Series B sales team effectively track their progress towards key performance indicators?

I use CRM dashboards that update in real-time to monitor essential sales performance metrics. Weekly pipeline reviews keep the team aligned on progress.

Monthly KPI scorecards track each rep's performance against targets. I create visual reports that highlight trends and identify areas needing attention.

Automated alerts notify me when metrics fall below thresholds. This allows for quick course corrections before problems compound.

I hold quarterly business reviews to analyze KPI trends and adjust targets based on market conditions. Regular forecasting sessions help predict future performance.

Which KPIs should a sales team prioritize to align with Series B growth objectives?

Revenue growth rate takes top priority since Series B investors expect 100-200% annual growth. I track this monthly and quarterly to ensure we stay on target.

Market expansion metrics like new customer acquisition and geographic penetration support scaling goals. Sales efficiency ratios help optimize resource allocation as we grow.

I prioritize KPIs that reflect team performance rather than just individual metrics. Team quota attainment and collective pipeline health matter most.

Product adoption rates within existing accounts drive expansion revenue. I measure feature usage and upgrade conversion rates to identify growth opportunities.

What are the best practices for setting realistic sales KPI targets post-Series B funding?

I base targets on historical performance data combined with growth projections. Adding 20-30% stretch goals motivates teams without creating unrealistic expectations.

Market research helps validate whether targets align with industry benchmarks. I adjust goals quarterly based on actual performance and market feedback.

Setting KPIs for sales representatives requires balancing individual and team objectives. I create tiered targets that reward both personal achievement and collective success.

I involve the sales team in target-setting discussions. This creates buy-in and ensures goals feel achievable while still driving growth.

Can you provide examples of sales KPIs that a Series B company should monitor for sustainable growth?

Net revenue retention rate should exceed 110% to demonstrate account expansion success. I track this metric monthly to ensure existing customers continue growing.

Sales team productivity measured by revenue per rep helps optimize hiring decisions. Average quotas of $1-2M annually work well for Series B SaaS companies.

Pipeline coverage ratio of 3-4x quota ensures adequate deal flow. I monitor this weekly to identify potential shortfalls early.

Win rate percentages above 20% indicate strong product-market fit. Customer churn rates below 5% monthly demonstrate sustainable business model health.

How does the scaling of a Series B company impact the selection and evaluation of sales KPIs?

Scaling requires shifting from individual to team-based metrics. I focus more on process efficiency and systematic performance rather than just outcomes.

Geographic expansion adds complexity to KPI tracking. I segment metrics by region and market to identify successful strategies for replication.

Team growth changes the evaluation timeline for KPIs. New hires need 3-6 months to reach full productivity, affecting short-term targets.

I introduce more leading indicators as the team grows. Activity metrics like calls per day and emails sent help predict future results before lagging indicators show trends.
