What Is an SDR in Sales? A Practical Look at the Role

A CEO asked me last month whether he should hire an SDR. The headcount was already sitting in next quarter's budget, put there by his sales director, and his question was the plain one: what is an SDR in sales, and what does one actually produce? B2B uses the title loosely. The job behind it is narrower, harder, and shorter-lived than most people assume.

I'm Raphael Presberg, Founder and CEO of Moriah, a LinkedIn Certified Marketing Partner. We run personal branding, targeted outreach, and LinkedIn Ads together as one business engine for established B2B companies. My starting position is that almost any business objective has an answer in the right LinkedIn strategy, which means the work an in-house SDR does is work my team does every day on behalf of clients.

What follows is the role as a job rather than as a box on an org chart: what an SDR does hour to hour, how it differs from an account executive and from a BDR, how SDRs are measured and compensated, what a realistic ramp looks like, and when a company is genuinely ready to hire one.

What is an SDR in sales?

An SDR, or sales development representative, is a salesperson hired to start qualified conversations and not to close them. They research target accounts, reach out to people who have never heard of the company, qualify the ones who reply, and hand those on to an account executive who owns the deal from there.

The SDR meaning in sales is narrow on purpose. One person opens, another closes, and the split exists because the two jobs reward opposite behavior. Closing rewards patience and depth across a handful of accounts. Prospecting rewards volume, repetition, and a high tolerance for being ignored. Give both to one person and prospecting is what slips, because there is always a live deal to chase instead. So the SDR fills the top of the funnel, the account executive works what arrives, and the pipeline becomes predictable enough to forecast against.

What an SDR does hour to hour

An SDR day splits into three blocks: building the target list, running outreach, and working the replies. The first block decides most of the outcome.

The research block

The day usually opens with research. The SDR turns the ideal customer profile into a list of named people worth contacting: the right function, the right seniority, at a company with some plausible reason to care this quarter.

This is what separates a productive SDR from a busy one. A list built on job title alone treats a thousand different people as one prospect, and the messages written from it read like they were written for nobody. Build the list on a real trigger instead, a new hire in a relevant function, a new location, a new service line, and the messages get read. Our own sales prospecting techniques rest on the same assumption: targeting sets the ceiling for everything downstream.

The outreach block

Then comes the sending: LinkedIn messages, emails, calls, or some mix of the three sequenced across a couple of weeks. In our own targeted outreach pillar we run roughly 200 carefully chosen LinkedIn messages a week for a client. That is the shape of a serious outbound motion, high intent per message rather than maximum messages per hour.

We run that outreach on LinkedIn rather than by cold email because of the reply rate. Cold email typically returns about 1 to 3 percent replies. Well-targeted LinkedIn outreach lands closer to 10 to 15 percent. That gap decides how many conversations one person can generate in a week, which in turn decides whether one SDR is enough.

The reply block

Most replies are not "yes." They are questions, objections, polite deflections, and referrals to someone else in the building. The SDR has to qualify fast: can this person buy, is there a real problem, is the timing plausible, and is it worth an hour of an account executive's week.

Then the part nobody puts in the job ad. Notes in the CRM, meeting invitations, handoff briefs so the AE walks in informed, sequences updated, prospects moved to nurture. An SDR who skips this makes the AE's job worse and the forecast unreliable.

The role is repetitive by design. An SDR sends far more messages than they get replies to and hears "no" more than anyone else in the company. The people who last are organized and resilient rather than charismatic, a rarer profile than the salary band suggests and most of why these teams are hard to staff.

SDR vs AE: the difference that matters

The difference between an SDR and an account executive is who owns the outcome. SDRs own conversations. AEs own revenue.

It shows up everywhere in practice. The SDR is measured on meetings and qualified opportunities, the AE carries a revenue quota. The SDR is thinking about this week, the AE about this quarter. And the AE seat is the most common promotion out of the role.

The handoff between them is where most sales development programs quietly fall apart. Once AEs decide the meetings are unqualified they stop taking them seriously, and the SDR's numbers can look healthy while the pipeline goes nowhere. A written, shared definition of a qualified opportunity is what keeps the function honest.

SDR vs BDR: mostly a naming convention

The textbook version of SDR vs BDR: SDRs qualify inbound demand, BDRs create new demand outbound. In practice plenty of companies use the two titles interchangeably, and plenty of people with "SDR" on their badge spend the whole day on cold accounts.

What matters when you structure a team is not the acronym. It is one question: is this person reacting to demand that already exists, or creating demand where none exists? Hand both jobs to one person and the outbound half usually gets neglected, because inbound leads are warmer and easier to work.

How SDRs are measured

The metric that matters is qualified meetings that actually happen and get accepted by an account executive. Published benchmarks put a productive outbound SDR at roughly 10 to 15 booked meetings a month, with about four in five actually taking place, and strong performers above 20.

Underneath that sits a ladder of numbers:

• Meetings booked and meetings held. The held number is the real one.
• Qualified opportunities accepted by AEs. The only metric the rest of the business feels.
• Reply and positive reply rate. The earliest signal that targeting or messaging is off.
• Activity volume. Useful for diagnosing a slump, dangerous as a goal in itself.

That last one is where sales development goes wrong most often. Tell someone their job is 400 messages a week and you will get 400 messages a week, most of them aimed at people who were never going to buy. The attainment data reflects it: published benchmarks put the share of SDRs hitting their number at around half, and lower than that in software.

One factor in those numbers sits outside the SDR's control, and it is the thing I would most want a CEO to understand before signing off on the hire. A decision-maker who gets an unexpected message looks at who sent it before deciding whether to answer. If the profile they find is empty, no content and no visible point of view, the message is dead however well it was written. Coaching does not fix that.

How SDRs are compensated

SDR pay is a base salary plus a variable component tied to meetings or qualified opportunities, usually split around 70 percent base and 30 percent variable. Published US benchmarks for 2026 put base salaries commonly between about $50,000 and $65,000, with on-target earnings frequently in the $75,000 to $95,000 range. Expensive metros and enterprise software companies push the SDR salary higher.

On-target earnings are a target, not a payslip. Since only about half of SDRs hit quota, a large share take home less than the figure in the offer letter, and that matters for retention as much as for budgeting.

The number the business should care about is the fully loaded one. Add benefits, tools, the manager's time, and the output you do not get during ramp, and an in-house SDR is commonly costed between about $110,000 and $150,000 a year. That is what the hire has to pay back. Not the base salary.

What a realistic ramp looks like

Plan for about three months before a new SDR produces at a normal rate, and closer to five before the seat reliably carries a full quota. Published averages sit across that band. A typical ramp runs like this:

1. Month one: learning. The product, the market, the objections, the CRM, the sequences. Output is low and should be.
2. Month two: volume without precision. Real outreach going out, real replies coming back, and the SDR still learning which conversations deserve an AE's time.
3. Month three: a partial quota. Meetings start landing consistently. Most companies set a reduced target here rather than the full number.
4. Month four or five: full quota. Assuming the targeting, the messaging, and the manager were all in place.

Set that against tenure. Median SDR tenure sits around 14 to 18 months, and annual attrition in in-house sales development teams is commonly reported between 30 and 39 percent. So a meaningful share of an SDR's time with you goes on ramping, and the seat often turns over not long after it becomes fully productive. That is an argument for building the function with replacement in mind, not for avoiding it: documented targeting, written sequences, and a manager who can onboard the next person quickly.

When a company is actually ready to hire an SDR

You are ready for an SDR when the people who can close have capacity they cannot fill with conversations. Not before.

Four conditions in practice:

• Someone can reliably close. If nobody converts meetings into revenue at a known rate, you are adding volume to a broken process.
• The ideal customer is known, not theoretical. An SDR executes against a defined target. A vague one produces a vague list.
• A manager owns the function. An SDR reporting to a founder who reviews the work every other Friday will not survive ramp.
• The deal economics support it. That fully loaded cost has to be paid back by the pipeline the seat generates.

Do the arithmetic before the hire. Say an SDR holds 12 meetings a month, a fifth turn into real opportunities, and you close a quarter of those at an average annual contract value of $30,000. Roughly seven closed deals a year, about $210,000 in new annual contract value, against a fully loaded cost near $130,000. The hire works. It is not the runaway win people expect, and it only works if those conversion rates are real rather than hoped for.

Signs you are not ready: your closers already have empty calendars, your offer changes every month, nobody has written down what qualified means, or you are hoping an SDR will tell you who your customer is.

Build in-house or outsource: the honest version

Both models work. Each fails in its own particular way.

The case for building in-house

An in-house SDR learns your product properly, sits in your sales meetings, absorbs the objections, and can be promoted into an AE seat. If sales development is going to be a permanent function you will want it in-house eventually, because a career path is not something you can outsource. The costs are recruiting, ramp, management attention, and a real probability of repeating the whole exercise within two years.

The case for outsourcing

Outsourcing buys speed and hands over the turnover risk, since the provider absorbs hiring and replacement and the program usually runs within weeks rather than months. Retainers get quoted anywhere from about $3,000 to $12,000 a month depending on the model and where the team sits, which puts the serious onshore options in roughly the same range as employing someone.

The failure mode is well known. A provider paid per meeting will book meetings, and if the qualification bar is loose your AEs end up on calls with people who were never going to buy. If you outsource, keep the definition of qualified in your own hands and measure the program on opportunities your AEs accept rather than on calendar invitations. The same trade-offs turn up when you weigh building in-house versus hiring an agency or look at B2B appointment setting services.

What neither option fixes

Employed or outsourced, an SDR is a delivery mechanism for messages, and neither model changes whether those messages land. That is decided before the message is sent. A decision-maker who receives outreach checks the sender, and what they find is the difference between a 2 percent reply rate and a 12 percent one.

Outreach performs when there is credibility behind it: an executive publishing a visible point of view, a company whose name the prospect has met before, and paid reach putting the right message in front of the right accounts at a moment when it is relevant. That is why we run personal branding, targeted outreach, and LinkedIn Ads together against one business objective instead of selling them separately. We have watched both halves of the failure pattern up close. A client who publishes good content but activates nothing around it gets attention and no business. A client running outreach from a profile with nothing behind it gets ignored. It is also why we lead with the executive's personal profile, since content from a personal profile performs roughly 5 to 10 times better than the same content from a company page.

Our own engagement is a monthly retainer, $4,000 a month in the United States, covering all three pillars run in-house by our team, with no commitment and no minimum term. That is a different purchase from an SDR seat. A seat buys activity capacity. What established B2B companies usually need first is the credibility that makes the activity work, which is why LinkedIn outreach and executive content belong in one motion rather than two separate projects.

Bringing it together

An SDR opens conversations so somebody else can close them. The role is narrow on purpose, measured on qualified meetings rather than revenue, paid as a base plus variable in roughly a 70/30 split, and it takes three to five months to become fully productive in a seat that often turns over inside two years.

Hire one when your closers have capacity, your customer is defined, and the arithmetic holds. Outsource when you want speed without the turnover risk, and keep the qualification bar in your own hands. Either way, decide what your buyers will find when they look you up, because that is what determines whether the outreach gets answered at all.

Frequently Asked Questions

What is an SDR in sales? An SDR, or sales development representative, is a salesperson whose job is to start and qualify conversations rather than close deals. They research target accounts, run outreach, qualify the people who reply, and hand qualified prospects to an account executive.

What does SDR stand for? SDR stands for sales development representative. The name describes the function: developing early-stage conversations to the point where a closer can take over.

What is the difference between an SDR and a BDR? In theory, SDRs qualify inbound demand and BDRs create new demand outbound. In practice many companies use the titles interchangeably, so ask what the person is responsible for instead of relying on the acronym.

What is the difference between an SDR and an AE? The SDR owns conversations and is measured on qualified meetings. The account executive owns revenue and carries a closing quota. One opens, the other closes, which makes the handoff the most important process in the team.

How much does an SDR earn? Published US benchmarks for 2026 put SDR base salaries commonly between about $50,000 and $65,000, with on-target earnings frequently in the $75,000 to $95,000 range. The split is usually around 70 percent base and 30 percent variable, so actual earnings depend on quota attainment.

How long does it take an SDR to ramp? Plan for about three months to a normal rate of production and closer to five before the seat reliably carries a full quota. Written sequences, defined targeting, and a graduated quota shorten it noticeably.

How many meetings should an SDR book per month? Roughly 10 to 15 booked meetings a month is a common benchmark for an outbound SDR, with about four in five actually taking place. Strong performers exceed 20, though the more useful measure is how many your account executives accept as real opportunities.

Is an SDR an entry-level role? Usually yes. Sales development is the most common entry point into B2B sales and the standard path leads to an account executive seat, though senior and enterprise-focused sales development roles do exist.

Should we hire an SDR or outsource sales development? Hire in-house if sales development will be a permanent function and you want the product knowledge and the career path to stay with you. Outsource if you want it running in weeks and prefer the provider to absorb hiring and turnover risk. Either way, hold the definition of a qualified opportunity yourself.

Do SDRs still cold call in 2026? Some do, and calling still works in particular markets, but most B2B sales development has shifted toward LinkedIn and email. Cold email typically returns about 1 to 3 percent replies while well-targeted LinkedIn outreach is closer to 10 to 15 percent, which is why the outreach we run for clients happens on LinkedIn.
