what is sdr in sales
An SDR in sales is a Sales Development Representative: the person who creates pipeline by finding, contacting, and qualifying potential customers, then handing good opportunities to closers like Account Executives (AEs).
What is an SDR in sales?
An SDR focuses on the early stages of the sales cycle: researching prospects, starting conversations, and deciding if a lead is worth a salesperson’s time. They bridge the gap between marketing-generated interest (leads from ads, content, events) and sales-ready opportunities that AEs can work and close.
Core responsibilities of an SDR
Typical day-to-day work includes:
- Researching target accounts and contacts.
- Doing cold outreach (email, calls, LinkedIn, sometimes video).
- Responding quickly to inbound leads (demo requests, webinar signups, form fills).
- Asking discovery questions to qualify fit, need, budget, and timing.
- Booking meetings for AEs or sales reps.
- Updating the CRM and tracking all activities.
Their success is usually measured in meetings booked and sales-qualified leads (SQLs) created, not deals closed.
Inbound vs outbound SDRs
Many teams split SDR work into two flavors:
- Inbound SDR
Handles leads that come to you (forms, trials, webinars, email signups), qualifies them, and follows up fast while interest is high.
- Outbound SDR
Proactively builds lists and reaches out to cold prospects via email, phone, and social to generate new interest.
Some companies use “SDR” mainly for inbound and “BDR” (Business Development Rep) for outbound, but the titles often overlap in practice.
Why the SDR role exists
Specializing prospecting into a dedicated role makes the whole sales team more efficient: SDRs focus on opening doors while AEs focus on running demos, managing opportunities, and closing revenue. Studies cited in industry content suggest companies with dedicated sales development functions see meaningfully higher conversion from lead to opportunity than those that don’t specialize this way.
Tools SDRs typically use
Modern SDRs are heavily supported by tech:
- CRM platforms (Salesforce, HubSpot) to track leads and activities.
- Email sequencing tools (Outreach, Salesloft) for automated but personalized follow-ups.
- Dialers to increase call volume and log calls.
- LinkedIn Sales Navigator and similar tools for targeting and research.
- AI assistants to help write tailored messages at scale.
With the right stack, one SDR can work far more leads with better consistency and data.
Career and role level
The SDR job is usually an entry-level sales position, especially common in B2B tech and SaaS, and is often a stepping stone into AE or other senior sales roles. Because it teaches prospecting, qualification, and communication fundamentals under pressure, it’s a common “first job” for people starting a sales career.
TL;DR: SDR = Sales Development Representative, the person responsible for generating and qualifying leads so closers can focus on selling and closing deals.
