Sales development
SDR vs BDR, and what a seat actually costs
The intended difference is direction of contact: SDRs qualify inbound, BDRs prospect outbound. Most companies use the titles interchangeably, so this page gives a decision rule based on the motion instead, then publishes the real economics on quota, ramp, attrition and cost per meeting from the one serious dataset on sales development.
What is the difference between an SDR and a BDR?
The intended difference is direction of contact: an SDR qualifies inbound leads that already raised a hand, and a BDR generates new conversations through cold outbound. In practice most companies use the titles interchangeably, so the title tells you very little and the job description tells you everything.
Both roles sit at the front of a sales organisation and hand qualified meetings to an account executive who closes. The distinction is about which direction the first contact travelled.
| Title | Usually works | Job | Reality |
|---|---|---|---|
| SDR, sales development representative | Inbound and marketing sourced leads | Qualify demand that already raised its hand, book the meeting, hand to an account executive | The more common title overall, and the one used for both motions when a company only has one team |
| BDR, business development representative | Outbound and cold prospecting | Generate demand that does not exist yet by researching accounts and starting conversations | In a minority of companies this title means partnerships or channel development instead, which is a third meaning entirely |
| In practice, most companies | Both, under one title | Whatever the pipeline needs that quarter | Roughly speaking, if a company has one team it is usually called SDR, and if it has two the outbound one is usually called BDR |
Most SDR vs BDR comparisons stop at the row above and present it as settled. If you are reading this because two job postings used different titles for what looked like the same role, that is not your misunderstanding. The industry genuinely does not agree, and the rest of this page is written on that basis.
What is an SDR in sales?
A sales development representative is an early career sales specialist whose entire job is producing qualified meetings for closers, not closing deals. SDRs own the first conversation, confirm the prospect is worth an account executive's time, book the meeting, and hand it over.
The role exists because of a division of labour argument. Finding and qualifying prospects and negotiating complex contracts require different skills and different temperaments, and separating them lets each person get better at one thing. The specialisation is real and so is its cost, which is a handoff where things get lost.
What an SDR is measured on, in descending order of how common it is: held meetings, meetings that convert to a first sales stage, pipeline value created, and activity volume. The last is the one most often used and the least informative, which the activity data further down this page makes fairly clear.
What an SDR is usually not responsible for: pricing, contracts, demos beyond a basic overview, closing, or account management after handoff. Where an SDR does run demos, the role is functionally a junior account executive with a different title.
What is a BDR?
A business development representative is a prospecting specialist who starts conversations with accounts that have shown no prior interest. The work is account research, finding the right person, and earning a first conversation through cold calls, email and social outreach.
A BDR's job is harder than an SDR's in one specific way: there is no existing interest to work with. An inbound lead has already decided it has a problem. A cold account has not, so the first conversation has to establish both that the problem exists and that it is worth solving now.
One confusion worth clearing up, because it catches people reading job postings. In a minority of companies, usually larger ones, business development means partnerships, channel and alliances rather than cold outbound. A BDR title in that context is a different job with a different skill set. Read the responsibilities rather than the title, and if the posting mentions quota carrying outbound activity it is the prospecting role.
Why do companies define these titles differently?
The titles spread faster than any standard for them. Sales development grew from a handful of companies in the early 2010s to a default function, and each organisation named the roles after whichever motion it built first, so the labels now encode company history rather than job content.
In other words, an SDR vs BDR argument inside a company is usually an argument about company history rather than about the work. Three patterns explain most of the variation we see. Companies that grew on inbound first called the whole function SDR and kept the name when they added outbound. Companies that grew on outbound first called it BDR and did the same. Companies that built both at once used the split as intended, which is the minority.
So the practical rule, and the short answer to SDR vs BDR as a question: when you are hiring, define the motion in the job description and stop worrying about the title. When you are being hired, ask what percentage of the pipeline is inbound, because that single number tells you more about the daily work than the title on the offer letter does.
What does an SDR actually do all day?
A median sales development rep completes about 112 activities a day across phone, email and LinkedIn, and converts those into roughly 4.1 quality conversations. Phone remains the largest single channel at 44 calls a day, slightly ahead of 41 emails.
The figures below come from the 10th edition of The Bridge Group's sales development research, published in February 2025 and based on 351 B2B companies, 83 percent of them B2B SaaS, with a median revenue of 47 million dollars.
| Daily activity | Median | Note |
|---|---|---|
| Total daily activities | 112 | The headline activity number, and the one most often quoted out of context |
| Phone calls | 44 | Still the largest single block despite a decade of predictions otherwise |
| Emails | 41 | Close behind calls, and the channel where deliverability has deteriorated most |
| LinkedIn touches | 19 | Now a standard part of the sequence rather than an experiment |
| Text and other | 8 | Small, and growing |
| Quality conversations per day | 4.1 | The number that actually predicts results. Phone centric teams reach 4.6 on 56 dials, email centric teams 3.4 on 28 dials |
The last row is the one worth sitting with. A hundred and twelve activities produce about four real conversations, which is a conversion rate of under four percent from touch to talk. Any plan that treats activity volume as the lever has to accept that the lever is this inefficient, and that pushing it harder is what trained the market to ignore outreach in the first place.
Note also the channel comparison in that row. Phone centric teams make roughly twice the dials of email centric teams and get 4.6 quality conversations against 3.4. More calls do produce more conversations, and the return is distinctly sublinear.
What is a realistic SDR quota?
The median quota is 10 held meetings a month, which is down roughly 40 percent since 2018. Quotas vary by how much qualification is required: 16 a month where the bar is an introductory conversation, about 9 where budget and authority must be confirmed first.
| Meeting definition | Median monthly quota | What it means |
|---|---|---|
| Introductory meetings | 16.0 per month | Lowest bar: the prospect agreed to a conversation. Highest quota because qualification happens later |
| Semi qualified meetings | 10.4 per month | Some criteria confirmed before the handoff. The most common arrangement |
| Fully qualified meetings | 9.0 per month | Budget, authority and need established first. Lowest quota, highest value per meeting |
| Global median, held meetings | 10 per month | Down roughly 40 percent since 2018 |
| Converted to a first sales stage | 6 per month | Down about 43 percent since 2018. Four in ten held meetings do not survive the handoff |
Two things to take from this table when you are setting a number. First, the definition moves the quota by nearly double, so a quota is meaningless without one. Teams that argue about whether 12 is reasonable are usually arguing about what counts as a meeting.
Second, look at the gap between the last two rows. Ten held meetings become six that convert into a first sales stage. Four in ten meetings an SDR works for do not survive the handoff, and that loss is a property of the model rather than a sign of a weak rep. If you compensate on held meetings only, you are paying for the ten and the business gets the six.
How many SDRs actually hit quota?
About 60 percent of sales development reps reached quota in the most recent research, the lowest figure in the study's history. Two thirds of companies report that between 50 and 89 percent of their reps are at quota, so a team where four in ten miss is normal rather than broken.
That number is worth holding onto, because plans are frequently built as though full attainment were the expected case. It also reframes the SDR vs BDR choice: at 60 percent attainment, which motion you pick matters less than whether the motion you pick is funded well enough to work. If you are modelling pipeline from a team of six SDRs at quota, the data says to model closer to four.
It also changes how you read an individual's performance. In a market where 40 percent of a large, mostly well managed sample is missing, missing is weak evidence about a particular rep in a particular quarter. The useful comparison is against the rest of your team and against the same rep's trend, not against the number on the plan.
Why is SDR quota attainment at an all time low?
Attainment fell because the channels got harder at the same time as the buying process got slower. Tighter bulk email rules, larger buying committees, and a market trained by a decade of volume outreach to ignore unknown senders all reduce conversations produced per unit of effort.
Email deliverability got harder
Bulk sender requirements tightened at the major mailbox providers, and the cold email tactics that worked in 2018 now land in spam or damage the sending domain. The same volume produces fewer conversations.
Buying committees grew and slowed
More stakeholders per decision means more meetings that stall for reasons no individual rep controls. The handoff conversion figure, six converted from ten held, is the visible edge of this.
Contract values rose, so quotas should have fallen more
Median selling price went from $27,000 to $44,000 between 2022 and 2024. Pipeline per rep rose to $3.78M mostly on price rather than activity, while meeting quotas fell 40 percent since 2018. Where quotas did not fall in step, attainment did.
Prospects stopped answering unknown numbers and unknown senders
Not a tactic problem. A decade of volume outreach trained an entire market to ignore it, and every team now pays that cost.
Some teams were overbuilt and are now being cut
Involuntary attrition at 13 percent against voluntary at 11 percent is unusual, and promotions fell from 34 percent of departures in 2020 to 16 percent. The career path narrowed at the same time the job got harder.
There is a mechanical point hiding in the third item that is easy to miss. Pipeline per rep rose sharply, from 2.83 million dollars in 2022 to 3.78 million, and the research attributes that mostly to higher contract values rather than more meetings. So the function is producing more pipeline value per head on fewer meetings. A business reading only the pipeline number would conclude sales development is getting more productive. A rep living the meeting quota would disagree. Both are looking at real numbers.
How long does an SDR take to ramp, and how long do they stay?
Average ramp is 3.0 months, the shortest the research has recorded since 2010. Average tenure is 1.9 years, with most companies reporting 12 to 23 months, and annual attrition sits at a median of 40 percent.
Put those three numbers next to each other and the economics of the role become clear. You invest three months before a rep is productive, you keep them for under two years on average, and you replace four in ten every year. A meaningful share of every SDR team is always ramping.
The composition of that attrition has shifted in a way worth noticing. Involuntary departures run at 13 percent, voluntary at 11 percent, and promotions at 16 percent, down from 34 percent in 2020. The traditional arrangement, where the job was hard but led to an account executive seat within two years, has weakened considerably. That matters for hiring: the promise that made the role attractive is harder to make honestly, and candidates have noticed.
The one encouraging number is ramp time falling to three months, the lowest in fifteen years of the study. Better onboarding and better tooling probably deserve some credit. So does a less forgiving market, where reps who are not working by month three may be exiting rather than ramping, which would shorten the average without improving anything.
What does an SDR seat actually cost?
A fully loaded SDR seat costs roughly 138,000 dollars a year once employer costs, tooling, a share of management and expected replacement are added to the 80,000 dollar median on target earnings. Against a median quota of 10 held meetings a month, that is about 1,150 dollars per meeting.
The build up, with the sources separated so you can disagree with the parts that are ours.
| Component | Annual | Basis |
|---|---|---|
| SDR on target earnings | $80,000 | Median, split 68:32 between a $55,000 base and $25,000 variable. Effectively flat since 2022 |
| Employer taxes and benefits | about $17,600 | Estimated at 22 percent of OTE. Varies widely by country and benefits package |
| Tooling per seat | about $4,000 | Contact data, dialler, sales engagement platform, CRM licence. Our estimate, not from the survey |
| Share of management cost | about $28,000 | A first line leader at $146,000 OTE loaded, divided across 6.4 reps |
| Expected replacement cost | about $8,000 | 40 percent annual attrition against a recruiting and lost ramp cost of roughly $20,000 per departure |
| Fully loaded, per year | about $138,000 | Our arithmetic on their medians. Treat it as an order of magnitude, not a quote |
This is the number that settles most SDR vs BDR debates in practice, because it applies to both. To be explicit about what is what: the on target earnings, the management pay, the ratio of reps per leader and the attrition rate are from the research. The tax and benefits percentage, the tooling figure, the cost per departure and therefore the total are our estimates. Your numbers will differ, and the shape will not.
Now the comparison that makes the seat defensible. Median raw pipeline per SDR is 3.78 million dollars a year, with half of companies between 1.9 and 6.4 million. Against a 138,000 dollar cost, even the bottom of that range looks strong until you remember that raw pipeline is not revenue. Apply a realistic win rate and the picture is sober but still positive at a healthy contract value, and stops working at a low one. That is the arithmetic to run before the first hire, and the reason the next section exists.
How should an SDR be compensated?
The median package is 80,000 dollars on target, split 68 to 32 between a 55,000 dollar base and 25,000 dollars of variable pay. The harder decision is what the variable pays on, and paying only on held meetings puts the rep and the business on different sides of the handoff.
Recall the gap from the quota table: ten held meetings become six that convert to a first sales stage. If variable pay is earned the moment a meeting is held, the rep is fully paid for an outcome the business only got 60 percent of. That is not a motivation problem, it is a measurement choice, and reps respond to it rationally by booking meetings that are easier to hold than to qualify.
What tends to work better is splitting the variable across both events. Part on the held meeting, because the rep controls that, and part on conversion into a first sales stage, because that is what the business is buying. The rep still carries risk on something partly outside their control, which is why the split should favour the part they own.
Two further notes from the compensation data. Median on target earnings have been effectively flat since 2022, with nominal growth of about 0.56 percent a year over the past decade, which in real terms is a significant decline. And the leadership ladder above the role has compressed: manager packages rose to 146,000 dollars from 127,000 in 2018, while director and vice president packages both edged down. Combined with promotions falling from 34 percent of departures in 2020 to 16 percent, the financial case for taking the job has weakened at both ends.
That matters for how you hire. If the historical pitch was low pay now in exchange for an account executive seat in two years, the data no longer supports making that promise casually. Teams that are honest about it and compensate accordingly do better on retention than teams repeating a career path that has narrowed.
How do you structure a team that runs both motions?
Split the team only when both motions are large enough to keep a specialist busy. Below roughly four reps, one pooled team handling inbound and outbound is more resilient. Above it, the SDR vs BDR split starts earning its keep because the two jobs reward genuinely different skills.
The argument for splitting is that qualifying a warm inbound lead and starting a cold conversation are different work. Inbound rewards speed, consistency and a good qualification conversation. Outbound rewards research, persistence and writing. A rep asked to do both tends to default to the inbound queue, because it is easier and the queue is visible, which quietly starves the outbound motion.
The argument against splitting early is capacity. With two or three reps, a split means one person per motion, and a single person is a sample size of one against a 40 percent attrition rate. One departure removes an entire motion.
So the practical sequence we recommend: start pooled with a protected block of outbound time that cannot be eaten by the inbound queue, measure which motion is actually producing, and split when the winning motion needs more than two people. At that point the SDR vs BDR naming resolves itself, because you will have two teams doing visibly different jobs and the titles will be describing reality rather than aspiration.
One structural detail worth copying from the data: 82 percent of companies now align reps to specific account executive territories, up from 56 percent in 2018. Pair rather than pool on the handoff side even while you pool on the sourcing side, because a rep who always hands to the same two closers learns what those two actually accept.
Should SDRs report to sales or to marketing?
Sales, in 60 percent of companies. Marketing owns the function in 26 percent and a C level executive in 10 percent. Reporting into sales aligns the team with the pipeline it feeds, and reporting into marketing usually reflects a function built to qualify inbound.
The argument for sales is handoff quality. The reps who receive the meetings and the reps who book them share a leader, which makes disputes about qualification a management problem rather than an interdepartmental one. Given that four in ten held meetings do not convert, having one person accountable for both sides of that number matters.
The argument for marketing is speed to lead and message consistency, and it is strongest when most of the pipeline is inbound. If the team's job is responding to demand that marketing created, putting it under marketing shortens the loop.
The arrangement that tends to cause trouble is a team under marketing with a quota set by sales and a definition of qualified that neither side wrote down. If that describes your setup, the reporting line is not the problem to fix first.
How many SDRs per account executive?
The overall ratio is 1 SDR to 2.4 account executives, and it has been steady since 2018. The single most common model is 1 to 2, used by 31 percent of companies. First line leaders carry 6.4 reps each, fewer at small companies and more at large ones.
Also worth knowing: 82 percent of companies now align SDRs to specific account executive territories, up from 56 percent in 2018. The drift toward pairing rather than pooling is one of the clearer trends in the data, and it makes sense given the handoff loss. A rep who always hands to the same two closers learns what those two actually want.
On management ratios, the spread by company size is large: 3.6 reps per leader below five million dollars in revenue, 8.1 at five hundred million and above. The small company figure is often read as inefficiency. It is usually the opposite, because at that stage the leader is also building the playbook, and thin management of a new function is how teams end up with a 40 percent attrition rate and no idea why.
When should you hire an SDR or BDR, and when should you not?
Hire when inbound exceeds what your closers can qualify within a day, or when you can name the specific accounts that should buy and say something particular to each. Do not hire before product market fit, below a contract value that can carry the seat, or to compensate for bad data.
Hire an SDR when inbound exceeds what AEs can qualify
If marketing produces more enquiries than closers can respond to within a day, the first SDR pays for itself in speed to lead alone. This is the clearest case and the least often the real one.
Hire a BDR when the category is known and the list is finite
Outbound works when you can name the few hundred accounts that should buy and say something specific to each. It fails when the list is a filtered export and the message is the same for everyone.
Do not hire either before product market fit
A prospecting team cannot find a repeatable message that does not exist yet. Founders should run outbound themselves until the conversation works, because the learning is the point.
Do not hire at a contract value that cannot carry the seat
At roughly $138,000 fully loaded and 120 held meetings a year, each meeting costs about $1,150. If your average contract is a few thousand dollars, the arithmetic needs a very high win rate to close.
Do not hire one SDR alone
A single rep gives you a sample size of one against a 40 percent attrition rate and no way to tell a bad hire from a bad market. Two is the realistic minimum experiment, which doubles the commitment you are actually making.
Do not hire to compensate for a weak list
Bad data defeats good reps. If the CRM cannot tell you which accounts are genuinely new, fix that before adding people whose job depends on it.
The last item is the one we are called about most often, and it is worth being blunt. No SDR vs BDR structure survives a contact base nobody trusts. Adding a prospecting team to a contact base that cannot distinguish a genuinely new account from a duplicate guarantees the team spends a meaningful share of its time on accounts that were already worked. The diagnosis and the fix are on our CRM data quality page, and the list building side without paying per record is on free B2B data enrichment.
What are the alternatives to building an SDR team?
The realistic alternatives are account executives prospecting their own smaller lists, far fewer accounts worked far more thoroughly, inbound built on commercial search intent, and signal based outbound triggered by something that actually changed at an account. Each suits a different contract value and sales cycle.
Account executives doing their own prospecting
Works at higher contract values where a seller can carry a small account list personally. Removes the handoff loss entirely, and costs you the specialisation that made the SDR model attractive.
Fewer, better researched accounts
A rep working 50 accounts properly beats one working 500 badly, and the data is not close. This is the single change we recommend most often, and it requires the account list to be real.
Fixing the data before adding people
Most teams we see are adding capacity on top of a contact base that cannot tell a new account from a duplicate. The CRM work is less interesting and usually produces more pipeline per dollar.
Inbound built on commercial search intent
Slower to start and cheaper per opportunity once it works, and it produces conversations where the prospect initiated. Not a replacement for outbound in every market, and a better first investment in some.
Signal based outbound rather than volume based
Reaching 40 accounts this week because something changed at each beats reaching 400 because they matched a filter. Needs the signals to be real and the research to be done, which is engineering work more than sales work.
Our bias, stated openly because it reflects what we sell: we think most teams at this stage get more pipeline per dollar from fixing the data and the research than from adding headcount, and that the inbound route is underweighted because it is slower to start. That is a genuine opinion formed from the work and it is not a neutral one. The figures on this page come from independent research, and you should weigh the recommendation knowing what we do for a living.
If the constraint is actually the go to market motion rather than the team, the B2B SaaS marketing and fractional CMO pages cover how that work is structured, and the marketing audit publishes the diagnostic we run before recommending anything.
FAQ
Common questions
What is the difference between an SDR and a BDR?
The intended distinction is direction of contact: SDRs qualify inbound leads that already showed interest, BDRs generate new conversations through cold outbound. Most companies use the titles interchangeably, so read the responsibilities rather than the title. Where a company has only one team it is usually called SDR, and where it has two the outbound team is usually called BDR.
What is an SDR in sales?
A sales development representative is an early career sales specialist who produces qualified meetings for account executives rather than closing deals. They own the first conversation, confirm the prospect is worth a closer's time, book the meeting and hand it over. They do not usually own pricing, contracts, closing or account management.
What is a BDR?
A business development representative prospects accounts that have shown no prior interest, through cold calls, email and social outreach. In a minority of companies, usually larger ones, the same title means partnerships and channel development instead, which is an entirely different job. Check whether the role carries an outbound activity quota.
Which title should we use when hiring?
Define the motion in the job description and do not worry about the title, because candidates cannot infer the work from it either. If you want one number that tells a candidate what the job is really like, tell them what percentage of pipeline is inbound.
Does the SDR vs BDR distinction actually matter?
The SDR vs BDR distinction matters as a description of two different jobs and not as a job title, because companies apply the labels inconsistently. Split the team when both motions are big enough to keep a specialist busy, which is usually above about four reps. Below that, one pooled team with protected outbound time is more resilient to a single departure.
How should an SDR be paid?
The median package is 80,000 dollars on target, split 68 to 32 between a 55,000 dollar base and 25,000 dollars variable. Pay part of the variable on held meetings, which the rep controls, and part on conversion into a first sales stage, which is what the business is actually buying. Paying only on held meetings pays fully for an outcome the business gets 60 percent of.
What is a realistic SDR quota?
The median is 10 held meetings a month, down roughly 40 percent since 2018. It varies with the qualification bar: about 16 a month where an introductory conversation counts, 10.4 where some criteria are confirmed, and 9.0 where budget and authority must be established first. A quota without a definition of meeting is not a quota.
What percentage of SDRs hit quota?
About 60 percent, the lowest in the history of The Bridge Group's research, with two thirds of companies reporting 50 to 89 percent of reps at quota. Model pipeline on roughly that rate rather than on full attainment, and treat an individual miss as weak evidence about that rep.
How long does it take to ramp an SDR?
Average ramp is 3.0 months, the shortest recorded since 2010. Average tenure is 1.9 years and annual attrition runs at a 40 percent median, so a meaningful share of any team is always ramping. Promotions have fallen from 34 percent of departures in 2020 to 16 percent.
How much does an SDR cost?
Median on target earnings are 80,000 dollars, split 68:32 between base and variable. Fully loaded with employer costs, tooling, a share of management and expected replacement, a seat runs roughly 138,000 dollars a year by our arithmetic, which is about 1,150 dollars per held meeting at the median quota of 10 a month.
Should SDRs report to sales or marketing?
Sales in 60 percent of companies, marketing in 26 percent and a C level executive in 10 percent. Sales aligns the people booking meetings with the people receiving them, which matters because four in ten held meetings do not convert to a first sales stage. Marketing suits teams whose pipeline is mostly inbound.
How many SDRs do you need per account executive?
The overall ratio is 1 SDR to 2.4 account executives and has been stable since 2018, with 1 to 2 the single most common model at 31 percent of companies. First line leaders carry 6.4 reps on average, 3.6 at companies under five million dollars in revenue and 8.1 at five hundred million and above.
When should you not hire an SDR?
Before product market fit, when the contract value cannot carry roughly 1,150 dollars per meeting, when you would only hire one, or when the CRM cannot tell a genuinely new account from a duplicate. In the last case the team will spend a real share of its time working accounts somebody already worked.
