A Sales Development Representative finds potential customers for B2B companies and determines whether those prospects are worth a sales team's time. SDRs solve a specific business problem: sales teams can't afford to chase every lead that walks through the door, so someone needs to separate serious buyers from tire-kickers before expensive resources get involved. SDRs work between marketing teams that generate interest and account executives who close deals, acting as the first human touchpoint in the sales process. Beginners often confuse this role with customer service or assume it's just cold calling all day, but the reality involves strategic research, multi-channel outreach, and qualification conversations that require genuine business understanding. If you’re exploring this field, structured programs like the CourseCareers Technology Sales Course can help you understand how tech sales actually works before committing to a career path, but this guide explains what SDRs actually do, the skills that matter, and how the role fits into a company's revenue engine.

What a Sales Development Representative Does Day to Day

SDRs start most days reviewing their pipeline of prospects to decide who needs follow-up and who's ready to pass to an account executive. You'll spend time researching companies to understand their business challenges, then reaching out through cold calls, emails, and LinkedIn messages with tailored messages that explain why your company's product might solve their specific problems. When prospects respond, you'll conduct discovery calls to ask questions about their current situation, budget, timeline, and decision-making process. The goal isn't to sell anything yourself but to gather enough information to determine if this prospect matches your company's ideal customer profile. You'll log every interaction in your CRM, update lead statuses, and coordinate handoffs to account executives when you've qualified someone as sales-ready. The rhythm alternates between outbound prospecting, inbound lead follow-up, and internal coordination with sales and marketing teams.

Key Responsibilities of a Sales Development Representative

SDRs generate qualified pipeline by identifying potential customers through research and outbound outreach. This means combing through databases like ZoomInfo or Apollo to find companies that fit your target profile, then crafting personalized messages that get responses instead of deletions. You'll qualify leads by conducting discovery conversations using frameworks like BANT or SPIN to understand budget, authority, need, and timeline. For example, if someone downloads a whitepaper, you'll call them to ask what problem they're trying to solve and whether they have budget allocated to fix it this quarter. You'll manage a consistent volume of daily activities, typically 50-80 calls, 50-100 emails, and 20-30 LinkedIn touchpoints depending on your company's strategy. You'll also maintain accurate records in Salesforce or HubSpot so account executives can pick up conversations without missing context.

Variations of the Role Across Different Work Environments

In early-stage startups, SDRs often wear multiple hats, handling some account executive responsibilities and helping refine messaging as the company figures out product-market fit. You might work closely with founders and have more autonomy to experiment with outreach strategies. At mid-sized tech companies, the role becomes more specialized with clear handoff points between SDRs and account executives, dedicated teams for inbound versus outbound leads, and established playbooks for every scenario. Enterprise organizations often segment SDR teams by industry vertical or company size, so you'd focus exclusively on healthcare companies or enterprise accounts with 5,000+ employees. The tools and sophistication increase with company size, but the core function stays consistent: find people who might buy, figure out if they're serious, and pass them to closers.

Common Misconceptions About This Role

Many beginners think SDRs are glorified telemarketers reading scripts to annoyed strangers, but effective SDRs research prospects thoroughly and start conversations based on genuine business relevance. Another misconception is that the job is purely about volume, when in reality, quality matters more than activity metrics once you understand the fundamentals. Companies track meetings booked and pipeline generated, not just dials made. People also assume SDRs need deep technical knowledge about the product they're selling, but your job is to identify problems and qualify interest, not to deliver product demos or handle technical objections. Finally, beginners often believe they'll be stuck in this role forever, when SDR positions are explicitly designed as stepping stones to account executive, sales engineering, or management roles within 12-24 months.

Skills That Make Someone Successful in This Role

Resilience and persistence matter more than natural charisma because rejection is constant and you'll probably hear "no" at least 20 times before you hear "yes." Strong written communication separates effective SDRs from struggling ones since email remains the primary outreach channel and prospects judge your professionalism based on grammar and clarity. Familiarity with your target market's region, dialect, and business culture helps you connect authentically, whether you're selling to Texas oilfield services companies or New York financial firms. Active listening during discovery calls lets you ask relevant follow-up questions instead of powering through a script while prospects mentally check out. You'll also need basic organizational discipline to manage 100+ active conversations simultaneously without dropping balls or losing track of promised follow-ups.

Tools and Systems Used by Sales Development Representatives

SDRs use Salesforce or HubSpot as their central workspace to log every call, email, and meeting while tracking prospect status through the qualification pipeline, creating a shared record that account executives can reference when they take over conversations. Sales engagement platforms like SalesLoft or Outreach automate email sequences and call workflows so you can maintain consistent touchpoints without manually tracking every follow-up, while also providing analytics on which messages generate the highest response rates. Prospecting databases like ZoomInfo and Apollo provide contact information and company details to build targeted lists, often including technographic data that shows which software companies currently use. LinkedIn Sales Navigator helps you research prospects, find warm introduction paths through mutual connections, and send personalized connection requests that don't feel spammy by highlighting shared interests or groups. Video messaging tools like Vidyard let you record personalized videos that break through crowded inboxes by adding a human face to your outreach, making it harder for prospects to ignore you. You'll also use calendar scheduling tools like Calendly to eliminate back-and-forth email chains when booking meetings, automatically syncing with your availability and sending reminders to reduce no-shows.

The Core Problems a Sales Development Representative Solves

SDRs solve the economic problem of sales team efficiency by ensuring account executives only spend time with qualified prospects who have real buying intent and budget, protecting the company's most expensive sales resources from low-probability opportunities. Without SDRs, account executives waste hours chasing leads that were never going to buy, driving up customer acquisition costs and slowing revenue growth while burning out your best closers on unproductive activities. SDRs also solve the market coverage problem by systematically reaching out to potential customers who haven't yet discovered your company through marketing channels, identifying ideal customer profiles that match your solution but aren't actively searching for it. This proactive outreach expands your addressable market beyond inbound interest and helps you reach buyers before they enter formal procurement processes where competitors already have relationships. Finally, SDRs solve the lead response time problem by immediately engaging prospects when they show interest, before competitors can establish relationships or before the prospect's urgency fades and the project gets deprioritized.

Where the Sales Development Representative Fits in a Team or Company

SDRs report to a Sales Development Manager or Director of Sales Development who sets activity targets and provides coaching on messaging and qualification techniques. You'll rely on marketing teams to generate inbound leads and create content you can use in outreach, while marketing depends on your feedback about which messages resonate and which prospects are low-quality. Your primary handoff relationship is with account executives, who need you to deliver thoroughly qualified prospects with clear next steps documented in the CRM. You'll also collaborate with sales operations teams who manage your tech stack and provide list-building support. Information flows through you in both directions: you surface market intelligence about competitor moves and buyer objections back to product and marketing teams, while they provide you with updated messaging and qualification criteria.

Common Career Paths for a Sales Development Representative

SDRs start at around $68,000 per year in base salary plus commission, with total compensation typically reaching $75,000-85,000 when you're hitting quota consistently. Within one to two years, strong performers move into Account Executive roles earning $100,000-210,000 per year, where you'll close deals instead of qualifying them. From there, the path splits between individual contributor and management tracks. Top-performing account executives can advance to Senior Account Executive positions earning $140,000-280,000 per year, then potentially to Enterprise Account Executive roles earning $190,000-580,000+ per year by managing large, complex sales cycles. The management track leads from SDR Manager earning $110,000-190,000 per year to Director of Sales or Director of Sales Engineering earning $150,000-250,000+ per year. This progression reflects consistent performance, relationship-building skills, and deep knowledge of your company's sales process.

Who's a Good Fit for This Career?

You'll succeed as an SDR if you can handle rejection without taking it personally and maintain consistent effort even when your pipeline feels empty. Strong written communication matters since you'll send dozens of emails daily that need to sound professional and personalized simultaneously. Understanding your target market's business culture helps you connect authentically, whether that means adjusting your approach for Southern hospitality or East Coast directness. You should be comfortable with structure and metrics since you'll track activity numbers and conversion rates constantly. People who need immediate gratification struggle here because building pipeline takes weeks or months before results show up. If you enjoy solving puzzles, researching companies, and figuring out what messages resonate with different audiences, the investigative aspect of this role will keep you engaged.

How Beginners Usually Learn What a Sales Development Representative Does

Most people discover SDR roles through LinkedIn searches for entry-level sales positions or by stumbling across job postings that don't require prior experience. They'll watch YouTube videos from sales influencers explaining prospecting techniques or read blog posts about cold email templates. Some join online communities like r/sales to ask questions and read war stories from working SDRs. The problem with this approach isn't that the information is wrong, but that it's scattered across hundreds of sources with no clear sequence or context about which skills matter most for getting hired. You'll spend weeks piecing together a fragmented understanding of the role without knowing which techniques hiring managers actually care about or which tools you need to learn first.
