What Is an SDR in Sales? Role, KPIs and When to Hire One

SDR means sales development representative. An SDR finds potential buyers, starts the first conversation, checks whether they fit, and books qualified meetings for the person who closes the deal. In short, the SDR fills your sales calendar so your closers can focus on selling.
If you run a growing business, you have probably felt the gap an SDR fills. Your best seller spends mornings building lists, chasing replies and updating the CRM. Meanwhile, deals that need attention wait. This guide explains what an SDR does, how to measure one, what the role costs and, most importantly, how to know when it is time to hire.
Key Takeaways
- An SDR works the top of the sales funnel: research, outreach, qualification and meeting booking.
- SDRs do not usually close deals. They pass qualified opportunities to an account executive (AE) or founder.
- Track SDRs on meetings held and pipeline created, not on activity alone.
- You likely need an SDR when closers spend more time prospecting than selling.
- Companies can hire SDRs in-house, use an agency, or add a dedicated virtual SDR.
What Does SDR Mean in Sales?
An SDR, or sales development representative, owns the first stage of the sales process. The role exists because finding and qualifying buyers takes a different skill set than closing them. Therefore, many companies split the work: SDRs create opportunities, and AEs convert them into revenue.
Some teams use the title BDR (business development representative) for a similar job. In many companies, SDRs focus on inbound leads while BDRs focus on outbound prospecting. However, the split varies by company.

What Does an SDR Do Day to Day?
A typical SDR day mixes research, outreach and admin. Here is what that looks like in practice:
- Builds prospect lists: finds companies and contacts that match your ideal customer profile (ICP).
- Runs outreach sequences: sends emails, makes calls and connects on LinkedIn in planned steps.
- Responds to inbound leads: follows up quickly with people who filled out a form or booked a demo.
- Qualifies prospects: asks about budget, need, timing and decision makers.
- Books meetings: schedules qualified calls on the closer's calendar.
- Keeps the CRM clean: logs every touch so leaders can trust pipeline data.
In addition, a good SDR feeds market insight back to the team. For example, they notice which job titles reply, which objections repeat and which messages fall flat.
SDR vs Account Executive: Who Does What?
The clearest way to understand the SDR role is to compare it with the role that comes next.
As a result of this split, each person spends their day on the work they do best. Without it, your closers end up doing both jobs, and neither gets full attention.
SDR KPIs: How to Measure Performance
Activity counts are easy to track, yet they rarely tell the whole story. Instead, measure SDRs on outcomes first and activity second.
Set targets after the ramp period, not before. Meanwhile, review the numbers weekly with your SDR so small problems do not become big ones.
Skills a Strong SDR Brings
Great SDRs share a few traits. When you interview or evaluate candidates, look for:
- Clear writing: short, personal emails that sound human.
- Phone confidence: comfort with cold calls and quick objection handling.
- Curiosity: real interest in the prospect's business and problems.
- Resilience: steady effort through a lot of "no" and silence.
- Organization: disciplined CRM habits and follow-up.
- Coachability: willingness to test, learn and adjust scripts.
Tool familiarity helps too. Most SDRs work in a CRM such as HubSpot or Salesforce plus an outreach tool. Ask about relevant tools during matching rather than assuming every rep knows every platform.

When Should a Business Hire an SDR?
Many owners hire too late. They wait until revenue stalls, even though the warning signs showed up months earlier. Consider hiring an SDR when you see three or more of these signs:
- Your closers or founder spend more than a third of their week on prospecting.
- Inbound leads wait hours or days for a first reply.
- Your pipeline swings up and down from month to month.
- You know your ideal customer, but nobody reaches out to them consistently.
- Your CRM is full of stale leads that no one follows up on.
- You plan to add another closer and need meetings to keep them busy.
On the other hand, an SDR will struggle if you have no clear offer, no defined buyer, or no one to take the meetings. Fix those first, then add sales development capacity.
In-House, Agency or Virtual SDR: Which Model Fits?
Once you decide to add SDR capacity, you have three common options. Each one trades cost against control.
For many small and mid-sized companies, a dedicated virtual SDR sits in the middle. You get one person who works only on your accounts, follows your playbook and joins your team rituals..
What Does an SDR Cost?
Cost depends on location, experience and pay structure. In the U.S., SDR pay usually combines a base salary with commission or bonus tied to meetings or pipeline. On top of pay, employers cover payroll taxes and benefits. According to the U.S. Bureau of Labor Statistics, benefits make up roughly 30% of total compensation for private-industry workers.
Next, add recruiting time, onboarding, tools and management. Together, these costs explain why many SMBs test a virtual SDR before they build a full in-house team. You can review current role rates on our pricing page.
How to Set Up a New SDR for Success
Hiring is only half the job. To help a new SDR ramp quickly, prepare these items before day one:
- An ICP document: industries, company size, titles and pain points.
- A starter playbook: email templates, call talk tracks and common objections.
- Qualification rules: what counts as a sales-ready meeting.
- Tool access: CRM, outreach tool, calendar links and a data source.
- A weekly review: 30 minutes to go over numbers, calls and next tests.
Above all, agree on the handoff. The SDR should know exactly when and how to pass a meeting to the closer.
