How to Hire an SDR: The Complete Guide for B2B Companies

Hiring an SDR is one of the most important and most frequently botched decisions in B2B sales. A great SDR generates pipeline, accelerates revenue, and pays for themselves within 60 days. A bad hire costs you 3-6 months of lost productivity, $30K-$60K in fully loaded costs, and the opportunity cost of pipeline you never built.

At Alchemail, we work alongside in-house SDR teams and often replace the SDR function entirely for companies that are not ready to hire. After generating $55M+ in pipeline and watching dozens of companies navigate SDR hiring, we know what separates successful hires from expensive mistakes. This guide covers every step.

When to Hire an SDR (and When Not To)

Hire an SDR When:

• You have a proven outbound process (defined ICP, tested messaging, working infrastructure)
• You know your cost per meeting and cost per opportunity from existing campaigns
• You have a sales leader or AE who can manage and coach the SDR
• You have budget for $60K-$100K in fully loaded annual cost (salary + benefits + tools + management time)
• Your outbound motion is generating results and you need to scale volume

Do Not Hire an SDR When:

• You have not yet proven that cold outreach works for your business
• You do not have a playbook for the SDR to follow
• Nobody on your team has managed an SDR before
• You are hoping the SDR will "figure out outbound" for you
• You need results in 30 days (SDRs take 2-4 months to ramp)

If you are in the "do not hire" column, an agency is the better path. We run the entire outbound motion, deliver meetings, and build the playbook. Once you know what works, hiring an SDR to take it over is a much lower-risk decision. See our comparison of cold email agency vs. in-house.

SDR Compensation: What to Expect

Base Salary

Experience Level	Base Salary (US)	Total OTE
Entry-level (0-1 years)	$40,000-$55,000	$55,000-$75,000
Mid-level (1-3 years)	$50,000-$65,000	$70,000-$90,000
Senior (3+ years)	$60,000-$80,000	$85,000-$110,000

Variable Compensation

SDR variable pay is typically structured around meetings booked or opportunities created:

• Per meeting booked: $50-$150 per qualified meeting
• Per opportunity created: $200-$500 per qualified opportunity
• Quarterly bonus: $1,000-$5,000 for hitting or exceeding quota

Best practice: Tie at least 50% of variable compensation to opportunity creation, not just meetings booked. This incentivizes quality over quantity.

Fully Loaded Cost

Do not forget the hidden costs:

• Base salary: $50,000
• Variable compensation: $15,000
• Benefits (health, PTO): $8,000-$12,000
• Tools and software: $3,000-$6,000/year
• Management time: $5,000-$10,000 (portion of manager's salary)
• Training and onboarding: $2,000-$5,000
• Total fully loaded: $83,000-$98,000/year

Compare this to an agency retainer of $3,000-$7,000/month ($36,000-$84,000/year) that includes infrastructure, data, tools, and execution with no ramp time.

Writing the SDR Job Description

A good job description attracts the right candidates and filters out the wrong ones. Here are the essential components:

Role Summary

Keep it specific. "You will be responsible for generating qualified meetings through cold email and LinkedIn outreach for our B2B SaaS platform. You will own the top-of-funnel pipeline and work closely with our AE team to deliver 15-20 qualified meetings per month."

Key Responsibilities

• Build targeted prospect lists using Apollo, Sales Navigator, and Clay
• Write and test personalized email sequences
• Manage multi-channel outreach (email, LinkedIn, phone)
• Respond to positive replies and book qualified meetings
• Maintain CRM hygiene and accurate pipeline data
• Hit monthly meeting and opportunity quotas
• Collaborate with marketing on content-led outreach

Required Qualifications

• 1+ years in B2B sales development or a related sales role
• Experience with cold email tools (SmartLead, Instantly, or similar)
• Familiarity with prospecting databases (Apollo, LinkedIn Sales Navigator)
• Strong written communication skills (cold email is primarily a writing job)
• Organized and disciplined with daily workflow management
• Comfortable with rejection and persistent follow-up

Nice-to-Have

• Experience in your specific industry
• Familiarity with data enrichment tools (Clay, LeadMagic)
• Background in your target buyer's domain (selling to sales leaders? Former SDR experience is valuable)
• CRM proficiency (HubSpot, Salesforce)

Interview Process: How to Evaluate SDR Candidates

Stage 1: Resume Screen (5 minutes)

Look for:

• Previous SDR or BDR experience (ideal) or adjacent roles (customer success, recruiting, real estate)
• Evidence of hitting targets or quotas
• Strong writing ability (check their LinkedIn profile and any written materials)
• Tenure at previous roles (under 6 months is a red flag unless they can explain it)

Stage 2: Phone Screen (20 minutes)

Questions to ask:

1. "Walk me through your current outbound process from list building to booked meeting."
2. "What was your monthly meeting quota and how consistently did you hit it?"
3. "What tools have you used for prospecting and email sending?"
4. "How do you handle a prospect who says 'not interested'?"
5. "Why are you looking to leave your current role?"

What you are evaluating: Process knowledge, specific results, tool familiarity, and resilience.

Stage 3: Writing Exercise (30-60 minutes, take-home)

Give candidates a real scenario: "Here is our ICP: [description]. Here is a target company: [name]. Here is the contact: [name, title]. Write a 3-email sequence that you would use to book a meeting."

What you are evaluating: Research ability, writing quality, personalization, value proposition clarity, and CTA strength. This is the single most predictive exercise for SDR hiring.

Stage 4: Live Interview (45 minutes)

Deep-dive questions:

1. "Walk me through how you would research [specific company in your ICP] before writing an email."
2. "Your open rates are 55% but reply rates are 0.8%. What do you change?"
3. "You have been sending for 3 weeks with no meetings. What is your diagnosis process?"
4. "How do you prioritize when you have 500 prospects to contact this week?"
5. "Describe a campaign that did not work and what you learned from it."

What you are evaluating: Analytical thinking, problem-solving, and ability to diagnose and fix outbound problems. You want someone who thinks in systems, not just executes tasks.

Stage 5: Reference Checks

Always check references. Ask previous managers:

• "Was [candidate] coachable?"
• "How did they perform relative to peers?"
• "What was their biggest weakness?"
• "Would you hire them again?"

Onboarding an SDR: The First 90 Days

Week 1: Product and ICP Training

• Company overview, product demo, competitive landscape
• ICP deep dive: who you sell to, why, and what problems you solve
• Review 10+ recorded discovery calls and demo calls
• Shadow 3-5 meetings with AEs
• Study existing email sequences and learn what has worked

Week 2-3: Tool Training and First Emails

• Hands-on training with your tech stack (sending platform, CRM, data tools)
• Build their first prospect list (reviewed by manager before sending)
• Write their first email sequences (reviewed and edited by manager)
• Start sending at low volume (25-50 emails/day)

Week 4-6: Ramp and Coaching

• Increase sending volume to 100-150 emails/day
• Daily check-ins on replies, objections, and questions
• Weekly 1:1 with manager reviewing metrics and messaging
• First meetings booked (target: 5-10 in month 2)
• Begin A/B testing subject lines and messaging

Week 7-12: Full Ramp

• Sending at full volume (150-300 emails/day)
• Managing reply workflow independently
• Hitting 50-75% of monthly quota
• By end of month 3: hitting full quota (15-20 meetings/month)

Reality check: Most SDRs take 2-4 months to reach full productivity. Budget for this ramp period. If you need meetings immediately, an agency is faster. At Alchemail, we start delivering meetings within 2-4 weeks.

SDR Quotas and Performance Management

Setting Quotas

Metric	Entry-Level Quota	Experienced SDR Quota
Emails sent/day	100-150	150-300
Meetings booked/month	10-15	15-25
Opportunities created/month	3-5	5-10
Pipeline generated/month	$50K-$150K	$150K-$300K

Managing Underperformance

If an SDR is below 70% of quota for two consecutive months:

1. Diagnose: Is it an activity problem (not sending enough) or a quality problem (sending but not converting)?
2. Coach: Provide specific, actionable feedback on the area that needs improvement.
3. Set a performance improvement plan: 30-day plan with weekly milestones.
4. Decide: If performance does not improve within 30 days, make the change.

Frequently Asked Questions

How long does it take to hire an SDR?

Expect 4-8 weeks from job posting to start date. Add 2-4 months for ramp. Total time from "we need an SDR" to "SDR is producing pipeline" is 3-6 months. This is why many companies use an agency to bridge the gap.

Should I hire a remote or in-office SDR?

Remote SDRs have access to a larger talent pool and often cost less. In-office SDRs benefit from easier coaching and team energy. The best approach depends on your management style. If your manager can do effective remote coaching (daily standups, screen shares, call reviews), remote works. If not, in-office is safer.

What is the average SDR tenure?

The average SDR stays in the role for 14-18 months. This means you will be re-hiring regularly. Factor turnover into your planning. Some companies mitigate this by promoting top SDRs to AE roles, which extends tenure and motivates performance.

Should I hire one SDR or two?

If this is your first SDR hire, start with one. Prove the process works with one person before scaling. Two SDRs without a proven playbook means two people struggling instead of one. Hire the second SDR once the first is hitting quota consistently.

When should I use an agency instead of hiring an SDR?

Use an agency when you need results fast (under 60 days), do not have a proven outbound playbook, or do not have management capacity for an SDR. An agency like Alchemail brings infrastructure, data, and expertise from day one with no long-term commitment.
