What is Sales Development Representative (SDR)?
An SDR (Sales Development Representative) is a B2B sales specialist who qualifies inbound and outbound prospects through targeted outreach, discovery, and data-driven validation, then books meetings for account executives. SDRs rely on enrichment, cadences, and measurable KPIs to convert contacts into qualified pipeline opportunities for the revenue engine.
How does sales development representative (sdr) work?
SDRs operate at the top of the funnel to turn contacts into qualified meetings. The typical workflow: sourcing prospects (lists, intent signals, account targets), enriching records to verify title and context, personalizing outreach sequences, and qualifying via brief discovery calls or demo-reads. Qualification uses pre-defined criteria—company size, budget range, use case fit, and timeline—and is recorded in the CRM.
When prospects meet criteria, SDRs schedule a calibrated handoff to an account executive and attach enrichment and conversation notes. Managers monitor activity (emails/calls), engagement (reply/open rates), and outcomes (meetings, pipeline created) to refine target lists and cadences. Integration with enrichment tools reduces time wasted on bad contacts and increases conversion efficiency.
Why does sales development representative (sdr) matter?
SDRs are the velocity engine of enterprise and mid-market GTM motions: they generate initial pipeline, validate fit early, and surface market signals that inform messaging and product prioritization. Efficient SDR teams lower cost-per-meeting, reduce downstream churn from poor-fit demos, and increase forecast accuracy by producing timely, standardized qualification data.
Operationally, well-instrumented SDRs improve sales productivity—allowing AEs to focus on closing—while aggregated enrichment and clearer SLAs increase conversion from meetings to opportunities. The net result is faster pipeline growth with more predictable conversion rates and a tighter, actionable funnel for revenue leaders.
Sales Development Representative (SDR) example
A mid-market analytics SaaS hires a three-person SDR team to accelerate growth into competitive accounts. An SDR uses a Chrome prospector to find VP-level engineering contacts, runs multi-vendor enrichment to confirm role and tech-stack signals, sequences personalized outreach, and qualifies fit against revenue-defined criteria. When the prospect meets qualification thresholds, the SDR books a discovery meeting and logs enriched contact data and qualification notes in the CRM for the AE handoff.
SDR core responsibilities
- Core workflow — Prospecting, enrichment, outreach, qualification, and AE handoff; each step should be instrumented in the CRM.
- Primary metrics — Meetings booked, conversion rates, and pipeline influenced are primary outcome metrics; activity metrics diagnose problems.
- Data dependency — Data enrichment and role verification sharply reduce wasted outreach and increase meeting quality.
- Handoff discipline — Clear qualification criteria and SLAs for handoffs prevent churn between SDRs and AEs and protect conversion velocity.
Frequently asked questions
What's the difference between an SDR and a BDR?
SDRs and BDRs overlap but differ by scope. An SDR typically handles both inbound and outbound prospect qualification and focuses on booking meetings for AEs. A BDR is often more outbound-centric, focused on creating new leads through prospecting campaigns. Titles and responsibilities vary by company; align role definitions to KPIs and handoff SLAs to avoid ambiguity.
Which KPIs should I use to measure SDR performance?
Primary SDR KPIs include meetings booked, contact-to-meeting conversion rate, qualified opportunities generated, outreach response rate, and pipeline influenced. Track time-to-handoff and lead quality scores. Combine activity metrics with outcome metrics to identify coaching opportunities and data gaps—e.g., high activity but low meetings often signals targeting or data enrichment issues.
What are best practices for running an SDR team?
Manage SDRs with a playbook, daily activity targets, and weekly quality reviews. Enforce CRM hygiene and enrichment routines, set clear qualification criteria and SLAs for AE handoffs, and provide regular role-playing and call coaching. Use data to prioritize accounts and iterate on messaging; continuous enrichment reduces wasted outreach and improves meeting quality.
Upcell's products map directly to SDR needs. Prospector accelerates on-page discovery and contact capture, while Multi-vendor Enrichment verifies titles, emails, and technographics before outreach. Combining prospecting and aggregated enrichment reduces false positives, shortens time-to-meeting, and increases the quality of handoffs to AEs. For operations teams, integrating upcell data into cadences and CRM fields improves segmentation, personalization, and measurable SDR productivity.
