What Is SDR Sales? A Complete Guide to the Role

SDR stands for Sales Development Representative: the person on a B2B sales team who finds, researches and qualifies potential buyers, then books the ones worth a conversation into an Account Executive's calendar. An SDR starts conversations. They do not close deals.

It is the most common entry point into a B2B sales career and the least understood job on the revenue team, partly because the title changes meaning between companies and partly because the work is judged on a metric, meetings booked, that hides most of what the day actually contains.

This guide covers what the role is, what an SDR does hour by hour, how it differs from a BDR and an Account Executive, the skills that separate the top of the team from the bottom, how to get the job, the channels the work runs on, where it sits in the org chart, what it pays, and the tooling that decides whether the week is spent researching or selling. The benchmark numbers come from The Bridge Group's 2025 study of 351 B2B companies, cited where they appear.

What is an SDR in sales?

An SDR owns the top of the pipeline and nothing below it. They identify accounts worth approaching, research the people inside them, run the first outreach, hold the qualifying conversation, and hand over the ones that meet the bar. Contracts, pricing and negotiation belong to someone else.

That is the difference from a full-cycle rep, who does all of it: prospects in the morning, demos at noon, negotiates in the afternoon. Full-cycle works at low volume and high deal size, or in a company too small to split the work. Everywhere else it fails for a simple reason: prospecting is a volume habit and closing is a scheduled craft, and the same person given both will always sacrifice the first for the second, because the deal in front of them is worth more today than the pipeline they would have built for next quarter.

Splitting the two is what the SDR role exists to do. It also concentrates the practice: an SDR runs hundreds of first conversations a quarter, which is how a market gets learned quickly. In the 2025 Bridge Group data, teams staffed roughly one SDR for every 2.4 Account Executives, a ratio that has held since 2018.

Key responsibilities of an SDR

The job description usually lists six things. The order below is roughly how a week is actually spent, which is not the order most job ads imply.

• Building the target list. Working out which accounts fit the ICP, who inside them owns the problem, and which of those people show any sign of being in market. This is research, and it is the single largest consumer of an SDR's week.
• Outbound outreach. Email sequences, calls, LinkedIn messages and voicemails, run as a cadence rather than as one-off attempts. A defined number of touches over a defined window, stopping the moment someone replies.
• Inbound qualification. Responding to demo requests, content downloads and chat conversations, usually against a service level measured in minutes. Speed here is the cheapest conversion lever a company has, and the volume of that queue depends entirely on how well marketing's own content marketing for lead generation is working upstream.
• The qualifying conversation. Fifteen minutes to establish whether there is a real problem, whether this person can do anything about it, and whether now is the time. Frameworks such as BANT or MEDDIC give it structure; the skill is asking one more question instead of pitching.
• Booking and handing over. Getting the meeting into an AE's calendar with enough written context that the AE walks in knowing what was said. A booked meeting that no-shows or gets rejected by the AE does not count on most teams.
• Logging everything. Every call, email, reply and outcome in the CRM. Tedious, and the reason any of the numbers below can be trusted.

Those numbers are the second half of the job. SDRs are measured on activity and outcome together: touches per day, connect rate on calls, reply rate on email, meetings booked, meetings held, and opportunities the AE accepted. The outcome metric is the one that matters, and the median target is smaller than most people expect. The Bridge Group's 2025 study puts the monthly quota at 10 meetings held, down 40% since 2018, with 60% of SDRs hitting quota, the lowest share in the study's history. Targets fell and attainment still fell with them, which says something about how much harder the top of the funnel has become.

What this means for a B2B sales team: ten a month is roughly one every other working day. Before you raise a target, work backwards through your own reply and meeting rates to see what activity it actually implies, because the number that fell here was the target and attainment still fell with it.

Those two halves pull against each other, which is the tension the job is really about. Activity metrics are easy to hit and easy to game; outcome metrics are the only ones that produce pipeline. A manager who watches touches alone gets volume with no meetings, and one who watches meetings alone gets an SDR booking anyone who will say yes. The teams that work measure both and pay on the outcome.

The reason sits in the first bullet. Salesforce's February 2026 State of Sales research, a survey of more than 4,000 sales professionals, found the average seller spends 40% of their time actually selling, and 48% said they lack the bandwidth to do adequate cold outreach at all. Research, list building and admin eat the rest.

What this means for a B2B sales team: half your team is telling you the constraint is time, not skill. Coaching the pitch will not move that. Take the list building and the research off them first, then coach what is left.

SDR vs BDR vs Account Executive

These three titles cause more confusion than any others in sales, because companies use them inconsistently and candidates reasonably assume the words mean something fixed. They do not. What is consistent is the work.

SDR against BDR. The clean split is direction of travel. The SDR works interest that already exists and qualifies it. The BDR goes into accounts that have shown nothing and manufactures the first conversation. Outbound is harder, slower and converts worse per touch, which is why the two are often paid and targeted differently even when the day looks similar. Many companies collapse both into one title, and a good number use "BDR" for what this guide calls an SDR. Read the responsibilities section of the job ad and ignore the acronym.

SDR against Account Executive. The handoff is the boundary. An SDR's job ends when a qualified meeting is accepted; the AE's begins there and ends at signature. The AE owns discovery in depth, demos, pricing, procurement and the close. Compensation follows the same line: an SDR is paid on meetings and opportunities created, an AE on revenue closed. The interesting failure mode is a badly defined handoff, where SDRs book anything that agrees to a call and AEs reject half of it. Every healthy team defines, in writing, what makes a meeting acceptable, and pays the SDR on the accepted ones only.

Where segment comes in. Larger companies split the top of the funnel by market rather than by direction: an inbound team working demo requests, an outbound team working named enterprise accounts. The titles then attach to segments instead of to motions, which is a third convention on top of the two above. It is another reason to ask, in the interview, what the person in this seat actually did last week.

Essential skills every SDR needs

• Listening, more than talking. The qualifying call is won by the person asking the second and third question, not by the one delivering the pitch fastest. Most weak calls fail because the rep was waiting for their turn to speak rather than hearing the constraint the buyer just described.
• Writing. More outreach is read than heard. Short sentences, one idea, a specific reason for contacting this person, no throat-clearing. The ability to write four useful lines is the highest-leverage skill in the role and the rarest.
• Product and market knowledge. Not feature recall. Knowing which problem your product genuinely solves, which it does not, and what the alternatives are, so a prospect who is wrong for you can be disqualified in two minutes instead of twenty.
• Objection handling. "We already use someone", "no budget", "send me an email". These are the standard opening moves. The skill is a calm, non-defensive response that asks one question rather than argues.
• Time management. The day contains research, calls, email, replies, CRM work and meetings. Without blocked time the calls quietly disappear, because calling is the least comfortable activity on the list and always loses to the others.
• Resilience, understood correctly. Not the ability to absorb rejection, which is mostly a myth about thick skin. It is the ability to run the same process on Thursday afternoon as on Monday morning after four days of silence. Consistency under low feedback is the actual trait.

Nearly half of sales reps in the 2026 Salesforce study named cold calling the worst part of the job. The reps who do well are rarely the ones who enjoy it; they are the ones who scheduled it and stopped negotiating with themselves about it.

None of these are talents you either have or lack. They are built the same way in every team that builds them: listening back to your own recorded calls weekly, which is uncomfortable and worth more than any course; sitting in on the AE's discovery calls after a handoff, so you learn what a qualified meeting sounds like from the other side; and having one person read your outreach before it goes out during the first month. A new SDR who does those three things is usually ahead of a talented one who does not by the end of ramp.

How to become an SDR

The role is one of the few well-paid entry points into technology that does not require a specific degree or a portfolio. Five steps, in order.

• 1. Education, and what it is actually worth. Most postings ask for a bachelor's degree in business, marketing or communications, and most hiring managers will drop that requirement for a candidate who is obviously good on the phone. The degree opens the door at large companies. It decides nothing after the first interview.
• 2. Get any experience with strangers and targets. Retail, hospitality, recruitment, fundraising, support. All of it counts, because all of it is talking to people who did not ask to talk to you, against a number. Say so explicitly in the application rather than hoping the reader infers it.
• 3. Learn the tools before you are asked to. A free CRM tier, a sequencing tool's trial, LinkedIn's own sales certifications. Being able to say you have built a list, written a five-step cadence and logged the results puts you ahead of most first-time applicants, and it costs a weekend.
• 4. Apply like an SDR. This is the whole interview. A generic application from someone whose job is personalised outreach answers the question before you are asked it. Research the company, find the sales leader, write four specific lines about their market, and send them. Hiring managers hire the demonstration, not the CV.
• 5. Expect the interview to be a call. Most processes include a mock cold call or a written outreach exercise. Prepare an opener you can say out loud without reading, and prepare to be interrupted. What is being tested is whether you stay conversational when the script breaks.

The first 90 days are more structured than most new SDRs expect. Weeks one and two are product, market and tooling. Weeks three to six are supervised: calls reviewed, emails read before sending, a reduced target. From week seven the full cadence starts and the number becomes real. Ask about that structure in the interview, because a company that cannot describe its ramp usually does not have one, and a new SDR left to work it out alone is the most common reason a first sales job ends badly.

After that the path is well worn. Ramp to full productivity averages 3.0 months in the 2025 Bridge Group data, and average tenure in the seat is 1.9 years. The usual next step is an Account Executive seat, and the usual alternatives are team lead, sales operations, customer success or product marketing, all of which value the same thing: having spoken to hundreds of buyers in one market.

Outreach channels and the prospecting process

No channel works alone, and the mix matters more than any single one. A cadence is a defined sequence of touches across several channels over a fixed window, typically two to three weeks and eight to fourteen touches, with an explicit stop condition.

• Cold calling. Still the fastest way to a real conversation and still the least popular task on the team. Connect rates are low by design; the value is that one connect gives more information than twenty emails.
• Email sequences. The volume channel. Deliverability is a real constraint rather than a technicality: warmed domains, verified addresses, sensible sending limits and a hard stop on reply.
• Social selling and InMail. Commenting, connecting and messaging where the buyer already spends their day. LinkedIn is where the org chart is maintained by the people in it, which makes it the best research surface available and a reasonable message channel when the message is not a pitch.
• Events and webinars. The warmest list a company produces on its own. Attendance is an intent signal with a short shelf life, so the follow-up window is days rather than weeks.
• Referrals and existing customers. The highest conversion rate of anything on this list, and the most systematically neglected, because nobody's dashboard counts it.

The mechanics are worth stating plainly, because they are where most cadences fail. Touches should be spaced, not stacked: two or three a week, alternating channel, so the same person is not emailed twice on the same morning. Every sequence needs a stop condition that fires on any reply, including a negative one. Inbound is a different clock entirely, measured in minutes rather than days, and a demo request answered an hour later is a materially worse lead than the same request answered in five. And everyone who says no gets a date rather than a delete: circumstances change, and a "not now" from March is a better February list than anything you can buy.

The process that ties them together runs in one direction: build a list, pick the accounts with a reason to hear from you now, research enough to write one specific line, run the cadence, qualify whoever replies, book the ones that clear the bar, and recycle the rest with a date rather than deleting them. The part worth optimising is the second step. A cadence is a multiplier, and a multiplier on a list of people with no reason to care produces more noise, faster, which is the failure mode covered in our guide to automated sales. How many touches that cadence should carry, and how far apart to space them, is in our guide to sales cadence.

Where SDRs sit in the org chart

An SDR reports to a Sales Development Manager, who reports to a VP of Sales or a Chief Revenue Officer. In some companies the function reports into marketing instead, which usually reflects where the leads come from rather than a philosophical position, and it changes the incentives: an SDR team under marketing tends to be measured on volume of qualified leads, one under sales on opportunities accepted.

The two working relationships that decide whether the role is pleasant are lateral, not vertical. With marketing, the argument is always about what counts as a qualified lead, and it is settled by writing the definition down and reviewing rejected leads together rather than by escalating. With Account Executives, the relationship is a supply chain: the SDR feeds the AE's calendar, the AE feeds back which meetings were worth having. Teams that skip that feedback loop get SDRs optimising for meetings held and AEs quietly ignoring half of them.

Structurally, small companies run one or two SDRs shared across the whole AE team. As the team grows it splits, usually by motion first (inbound versus outbound) and then by segment or territory. A manager typically carries six to eight reps, and the 2025 Bridge Group data puts staffing at roughly one SDR per 2.4 AEs, so the size of the sales development team is a function of how many closers there are to feed. For how the whole motion fits together either side of that handoff, see our guide to SaaS software sales.

SDR salary and career growth

In The Bridge Group's 2025 SDR Models and Metrics study of 351 B2B companies, median SDR on-target earnings were $80,000, split 68:32 between a $55,000 base and $25,000 of variable pay at full attainment. That OTE figure has been unchanged since 2022, which in real terms means the role has taken a pay cut.

Four things move an individual number away from that median:

• Segment. Enterprise SDRs earn more than SMB SDRs, because the accounts are harder and the cycles longer.
• Location. A US metro premium is real, and remote roles are increasingly priced against the market rather than the city.
• Motion. Pure outbound usually pays above pure inbound for the same seniority.
• Attainment. The variable third is not guaranteed. With 60% of SDRs at quota in 2025, a meaningful share of the market earns closer to base than to OTE.

The growth path is steep if you stay in sales. The same study puts median SDR manager OTE at $146,000, director at $189,000 and VP at $240,000. The common route is 18 to 24 months in the seat, then an AE promotion, where earnings become a function of deal size rather than meeting count. The alternative route, into management, comes faster in a growing team and is a genuinely different job: recruiting, coaching and forecasting rather than prospecting.

Tools and technology that make the job possible

Four categories, and an SDR touches all of them daily. The CRM is the record: accounts, contacts, activity and the pipeline the team is judged on. The sales engagement platform runs the cadences and the calls. Data and enrichment tools resolve a name into a contactable person with a verified address. Intent and signal tools decide who is worth contacting at all, by reading public behaviour rather than filtering a static database. Our comparison of B2B sales tools covers the specific vendors in each, and our intent provider comparison goes through that last category on its own, since the five kinds of product sold under the label answer very different questions.

The productivity case is not abstract. In the 2026 Salesforce study, 55% of sales professionals were already using AI for prospecting, and sellers expected fully implemented agents to cut prospect research time by 34%. Applied to a role where research is the largest block in the week, that is the difference between a calendar built on twenty conversations and one built on eight.

What this means for a B2B sales team: research is the largest block in an SDR's week, so a third off it is the single biggest lever you have on their calendar. Point the tooling there before you point it at writing the email.

"We want to kill the busywork so our teams can focus on what actually moves deals forward: building relationships and driving success."
