Short answer: An SDR (sales development representative) usually handles inbound leads or does the first outreach to qualify prospects, while a BDR (business development representative) usually focuses on outbound prospecting into target accounts. In practice, companies use the two titles differently, and many treat them as the same job. What matters is the work, not the title.
- SDR: often qualifies leads and books meetings, sometimes inbound.
- BDR: often hunts new accounts through outbound.
- Reality: titles vary by company, so read the job description.
What is the difference between an SDR and a BDR?
The most common split looks like this. An SDR works on leads that come from marketing or from lists, qualifies them, and sets meetings. A BDR goes after specific target accounts, often larger ones, through outbound work, and builds relationships with them over time.
Plenty of companies reverse that, or use only one title. Some use SDR for the junior role and BDR for the same role with more experience. Others use BDR to mean someone who looks for partnership and growth opportunities beyond direct sales. Ask any company what its own definition is.
How do the roles compare?
| Area | SDR (typical) | BDR (typical) |
|---|---|---|
| Main focus | Qualify leads and book meetings | Open new target accounts |
| Lead source | Marketing leads, lists, inbound and outbound | Mostly outbound to chosen accounts |
| Deal size | Often smaller or mid-sized deals | Often larger accounts |
| Cycle | Faster hand-off to a closer | Longer, relationship-driven |
| Skills | Speed, volume, clear qualifying | Research, patience, multi-contact outreach |
| Success measure | Meetings or qualified leads | Meetings or opportunities in named accounts |
Treat this table as a general pattern, not a rule. If you are hiring, define the job in your own terms. For the basic role, read about outsourced SDR teams.
Which one does your company need?
Ask what you need done, then pick a title that fits.
You need someone to work inbound leads
If marketing generates form fills and demo requests, you need quick follow-up and basic qualifying. That is SDR-style work. It relies on speed and a good process for B2B lead qualification.
You need someone to open specific accounts
If you sell to a defined list of larger companies, you need someone who researches each account, finds the right people, and reaches them in several ways. That is BDR-style work and overlaps with account-based marketing.
You need both
Larger teams hire for both and split the work by source or account size. A small company rarely needs both at the start. One outbound person, or an outsourced team, is usually enough to learn what works.
What about the sales team structure around them?
Neither role closes deals in most setups. They feed account executives, so you need closers who can take the meetings. A company with many meetings and no one to run them has wasted its money. Our post on B2B sales team structure shows how the roles fit together.
It also helps to define hand-off rules. What counts as qualified? Who takes the meeting? How fast must follow-up happen? Without answers, even a great SDR or BDR creates friction. Read sales and marketing alignment for related problems.
Is it better to hire, or to outsource?
Hiring gives you control and a person who learns your product. It also gives you recruiting, training, management and turnover to deal with. Outsourcing gives you a team and a process that already work, with less direct control. Which is better depends on your volume, budget and management time.
Our own service is cold email only. We build a list you approve, write and send the emails, and pass you the replies. Growth and Scale plans also book the meetings. We do not do cold calling or LinkedIn outreach, so if you need those channels, you will want a different provider or a hire. For the cost side, see our SDR cost calculator.
How do you write a job description that avoids confusion?
- Say what channels the person will use: email, phone, social.
- Say where leads come from.
- Say whether they work named accounts or open lists.
- State the meeting target and what qualifies.
- State who they report to and who takes their meetings.
Clear duties beat clever titles. Candidates and managers both benefit when the work is spelled out.
What do the two roles have in common?
More than the titles suggest. Both roles live on persistence, organization and the ability to write short, relevant messages. Both work from a target list, both log activity in a CRM, and both are judged on meetings that turn into real opportunities. Both also face a lot of rejection and need steady coaching to improve.
That is why the best predictor of success is usually not the title but the setup: a clear buyer, a good list, a sound offer and a manager who reviews the work. If those are in place, an SDR or a BDR can do well. If they are missing, neither will, and renaming the job will not help.
If you are weighing the two for a small team, start from the outcome you want, such as ten qualified meetings a month with mid-sized manufacturers, and work backwards to the person and process that could deliver it. Then pick the title that makes sense to candidates in your market.

Frequently asked questions
Is a BDR higher level than an SDR?
At some companies yes, at others no. Titles are not standard, so check the actual duties and pay.
Can an SDR become a BDR?
Yes, often. Many companies move SDRs into account-focused or senior roles, but paths differ.
Do I need both roles?
Probably not at first. Start with one outbound function, either a hire or an outsourced team, and add specialists as volume grows.
Which one costs more?
It varies by company and seniority. A role aimed at larger accounts often pays more, but that is not universal.
