SDR (Sales Development Representative): definition, responsibilities and guide

An SDR (Sales Development Representative) is a sales professional who specializes in top-of-funnel prospecting: their role is to identify prospects, qualify them and book meetings for Account Executives. They don’t sign contracts. They generate the opportunities that AEs will then work on.

The SDR is the first link in the B2B sales pipeline. Without SDRs structuring the top of the funnel, Account Executives spend a significant share of their time prospecting – time taken away from closing, which is where they truly create value.

In the highest-performing B2B sales organizations, the SDR is the entry point of a structured inside sales model: outbound prospecting, inbound qualification and handoff of qualified meetings to the AE in charge of closing.

Before hiring an SDR, a company needs to check three prerequisites: a clear target, a sufficiently tested value proposition and a qualification process shared with the Account Executives. When these elements are not yet stable, outsourced prospecting limits the risk of hiring too early.

What is an SDR? Definition and position in the sales team

The Sales Development Representative is a salesperson entirely dedicated to the top of the sales funnel. Their scope ends with the handoff of the qualified meeting: they are not responsible for closing, negotiation or the post-signature customer relationship. This specialization is what makes the SDR/AE model more effective than a generalist salesperson who handles both roles.

In France, the term is often translated as “développeur commercial” or “commercial sédentaire de prospection”, but the English terminology has become the standard in SaaS and scale-up ecosystems. SDRs work almost exclusively remotely or in the office, with no field travel.

SDR, BDR, AE, AM, Inside Sales: the complete glossary of B2B sales roles

These roles are often confused, even within well-structured teams. Here is the complete reference:

Role Main mission Scope Key output
BDR Pure outbound prospecting: identify and approach target accounts New markets, unknown strategic accounts Qualified outbound leads
SDR Outbound prospecting + inbound lead qualification: convert into qualified meetings The entire top-of-funnel pipeline Qualified meetings handed over to the AE
AE Run sales cycles, negotiate and sign contracts Middle and bottom of the funnel (advanced qualification, closing) Signed contracts, revenue generated
AM Manage and grow the existing customer portfolio Active customer base Retention, upsell, renewal
Inside Sales Full-cycle remote selling: prospecting + closing on short cycles Low- to mid-value deals, high volume Revenue generated independently

In practice, the SDR/BDR distinction is often theoretical in French B2B SMEs: the same person handles both missions. Specialization tends to take hold in scale-ups and in organizations with more than 20 salespeople.

Where the SDR fits in the sales funnel

The SDR works exclusively at the top of the funnel, between the suspect stage and the SQL handed over to the AE. Their work covers three stages:

  • Identification and targeting: build or enrich a prospecting list aligned with the ICP, combining firmographic data and buying signals
  • Prospecting and first contact: start the conversation via cold calls, cold emails or LinkedIn outreach, with the aim of triggering a first qualifying exchange
  • Qualification and meeting booking: validate the BANT criteria during the discovery call and book a slot with the AE only if the prospect is mature enough

The quality of this qualification work directly determines the AE’s close rate. A poorly qualified meeting handed over is an hour lost for the senior salesperson. That is why qualified appointment setting is the main output on which an SDR is evaluated.

An SDR’s daily responsibilities

Outbound prospecting: cold calls, cold emails, LinkedIn

Outbound prospecting is the core of the SDR’s job. A typical day in B2B SaaS includes 60 to 80 calls, 80 to 120 emails sent within structured sequences, and 20 to 30 LinkedIn connection requests or messages.

These volumes may seem high. They are explained by the conversion rates of the outbound channel: a 10% connect rate on cold calls means the SDR has to make 10 calls to speak with 1 prospect. Out of 10 conversations, 1 to 2 turn into a qualified meeting on average.

The effectiveness of outbound prospecting depends on the quality of the prospecting sequence: the right message, at the right time, on the right channel, with the right follow-up cadence. Building an effective prospecting sequence is one of the core skills of a high-performing SDR.

Qualifying inbound leads (inbound SDR)

In organizations where marketing generates inbound leads (forms, demo requests, content downloads), the SDR also qualifies these contacts. Their role is to separate genuinely mature MQLs from curious contacts with no short-term buying intent.

Inbound qualification is generally easier than outbound: the prospect has already shown a sign of interest. But it requires the same rigor on the BANT criteria – a completed form does not qualify a budget, decision-making authority or a decision timeline.

Booking meetings and handing off to the Account Executive

The SDR-to-AE handoff is a critical moment in the pipeline. A meeting handed over without qualification context is a meeting that gets off to a bad start. The best organizations formalize this handoff with a standard briefing document: stated need, budget mentioned, objections raised, stakeholders identified, timeline.

An AE who receives this briefing can open the first meeting on the prospect’s specific challenge rather than with a generic pitch. This preparation explains part of the gap in close rates between structured and informal teams.

CRM management and prospecting sequence follow-up

SDRs spend 20 to 30% of their time on CRM tasks: updating contact statuses, logging qualification notes, scheduling follow-ups, scoring prospects. This time is often underestimated during hiring, which leads to poorly documented pipelines and insufficient follow-up rates.

The most widely used tools: HubSpot or Salesforce for CRM, Lemlist, Outreach or Salesloft for automated prospecting sequences, Kaspr or Lusha for contact data enrichment.

KPIs of a high-performing SDR: 2025 benchmarks by sector

An SDR without quantified targets is an SDR without management. The benchmarks below come from Oliverlist campaign data for 2024-2025, cross-referenced with French B2B market standards.

KPI B2B SaaS B2B services Industry / key accounts
Calls made per day 60 to 80 40 to 60 20 to 40
Emails sent per day 80 to 120 50 to 80 30 to 50
LinkedIn connections per day 20 to 30 15 to 25 10 to 20
Cold call connect rate 8 to 12% 10 to 15% 12 to 18%
Qualified meetings / calls made 1 to 3% 2 to 4% 3 to 6%
Qualified meetings handed to the AE / month 15 to 25 10 to 18 5 to 12
No-show rate 10 to 20% 8 to 15% 5 to 10%
Meeting-to-opportunity conversion rate 30 to 45% 35 to 50% 40 to 60%

These benchmarks should be interpreted with caution: the sector, target size, market maturity and quality of the prospecting list all have a direct impact on conversion rates. An SDR prospecting large industrial accounts cannot be evaluated against the same volume targets as an SDR in low-touch SaaS.

How to manage an SDR’s performance day to day

An SDR’s performance is managed on two levels: activity (volume of calls, emails, connections) and conversion (qualified meeting rate, successful handoff rate to the AE). Managing volume alone leads to low-quality prospecting. Managing conversion alone without a minimum level of activity leaves too much room for inaction.

Three indicators to track every week, without exception:

  • Qualified meetings / meetings booked ratio: below 50%, the targeting or the qualification script needs rework
  • No-show rate: above 15%, the post-booking confirmation process is failing
  • Meeting-to-AE-opportunity conversion rate: an indicator of handoff quality – if the AE regularly reclassifies the meetings received, the problem lies in the SDR’s qualification threshold

How much does an SDR cost and what ROI can you expect?

SDR salary in France

An SDR’s salary in France varies with experience, sector and location:

  • Junior SDR (0 to 2 years): €28,000 to €38,000 gross base salary, with variable pay of €5,000 to €10,000 depending on targets. Mainly in the Paris region (Île-de-France) and in startup/SaaS ecosystems.
  • Experienced SDR (2 to 4 years): €35,000 to €48,000 base, variable pay of €8,000 to €15,000. A profile able to take charge of a full prospecting vertical with little supervision.
  • Senior SDR / SDR Team Lead (4+ years): €45,000 to €60,000 base, significant variable pay. A rare profile, often transitioning to an AE or sales manager role.

Reference sources for up-to-date salary ranges: Glassdoor, Welcome to the Jungle, Figures.hr (French SaaS benchmark).

Total cost of an in-house SDR: beyond salary

Gross salary is only part of the real cost of an in-house SDR. For a junior profile in the Paris region, the full annual cost breaks down as follows:

  • Gross salary: €32,000
  • Employer social contributions (~42%): €13,500
  • SDR tool stack (CRM, sequencer, enrichment, LinkedIn Sales Navigator): €4,000 to €8,000/year
  • Training and onboarding: €2,000 to €5,000 in the first year
  • Management and coordination (manager time): equivalent to €5,000 to €8,000

Estimated total annual cost: €56,000 to €66,000. On top of this comes the opportunity cost of the first 3 to 6 months, during which the SDR is ramping up and not yet generating meetings at the target pace.

How to calculate an SDR’s ROI

Calculating an SDR’s ROI requires three data points: the number of qualified meetings generated per month, the AE’s close rate on those meetings, and the average value of a signed contract.

Example for a B2B SaaS company with an average ACV (Annual Contract Value) of €15,000:

  • Junior SDR generating 15 qualified meetings / month
  • Meeting-to-opportunity conversion rate: 35%, i.e. 5.25 opportunities / month
  • AE close rate: 25%, i.e. 1.3 contracts signed / month
  • Revenue generated / month: 1.3 x €15,000 = €19,500, i.e. €234,000 / year
  • Annual SDR cost: €60,000 – gross ROI: 3.9x

This calculation is simplified: it does not account for the sales cycle (meetings from month 1 don’t close before month 3 or 4). Nor does it include the cost of turnover, which is the most underestimated factor in the build vs buy decision.

The average tenure of an SDR in France is 18 to 24 months. Over that period, 3 to 6 months are consumed by ramp-up. That leaves 12 to 21 months of full productivity before a new hiring cycle (€3,000 to €8,000 in fees) followed by another ramp-up. Adding these costs up over 5 years, the real cost of an in-house SDR significantly exceeds the stated gross annual cost. This is the calculation most executives fail to make when weighing in-house against outsourcing.

In-house SDR or outsourced prospecting: which should you choose?

This is the question most B2B executives and Heads of Sales reading this article are asking themselves. The answer depends on team size, growth stage, product complexity and how quickly you need results.

Criterion In-house SDR Outsourcing (agency)
Total annual cost €45,000 to €65,000 (salary + social contributions + tools + management) Cost per qualified meeting (€200 to €600) – zero fixed costs
Time to first meetings 3 to 6 months (hiring + onboarding + ramp-up) 2 to 4 weeks (process already well established)
Sector expertise To be built – depends on hiring and training Available immediately if the agency specializes in your sector
Scalability Limited by the SDR’s individual capacity Scales with the target meeting volume, with no HR constraints
Process control Full – pipeline, messaging and targeting managed in-house Shared – real-time reporting, but less granularity
Product knowledge Excellent if well onboarded – a major asset on complex deals Partial – transferred through briefs and training sessions
Turnover risk High – average SDR tenure: 18 to 24 months in France None – the agency absorbs its own team turnover
Recommended for Teams with > 5 AEs, long cycles, complex products B2B SMEs, hypergrowth startups, testing a new market

Decision grid: when should you outsource your SDR function?

Outsourcing makes sense in four situations:

  • Your team has fewer than 4 to 5 AEs: the ROI of an in-house SDR is hard to justify below this threshold, because the meeting volume needed to absorb the fixed cost is not reached
  • You need results fast: hiring an SDR takes 6 to 10 weeks, and onboarding another 4 to 8 weeks. A specialized agency can generate the first meetings within 2 to 4 weeks.
  • You want to test a new market or a new target without hiring risk: outsourcing lets you quickly validate the relevance of a segment before assigning permanent resources to it
  • You have just lost your SDR: high turnover in this role is a reality. Rather than restarting a 4- to 6-month hiring cycle, an agency keeps the flow of meetings going without interruption

Oliverlist is a B2B prospecting agency specializing in generating qualified meetings for sales teams. Campaigns are up and running in under 3 weeks, with weekly reporting and results-based billing.

OLIVERLIST IN NUMBERS

  • More than 50,000 qualified meetings generated since 2017 for B2B clients in France and across Europe
  • Average qualification rate: 58% of booked meetings meet the client’s BANT criteria
  • Average time to first meetings: 18 days after campaign launch
  • Sectors covered: SaaS, IT services, industry, logistics, finance, HR, marketing
  • Average tenure of Oliverlist SDRs: 3.2 years (vs 18-24 months French market average)

How to hire and onboard a good SDR

Key skills to assess when hiring

A good SDR is not necessarily an experienced salesperson. Above all, they are rigorous, resilient and able to learn fast. The skills most predictive of performance:

  • Resilience in the face of rejection: cold calling involves a failure rate of 90% or more. An SDR who loses motivation after 20 consecutive rejections won’t last 6 months.
  • Curiosity and listening skills: the best qualification questions don’t come from a script learned by heart, but from a genuine interest in the prospect’s problems.
  • Process discipline: CRM management, sequence follow-up, sticking to follow-up cadences. A disorganized SDR produces an unreadable pipeline.
  • Adaptable messaging: the ability to adjust the pitch in real time to the prospect’s profile, sector and the signals picked up during the call.

In interviews, favor real-life role plays (cold call role play, qualification exercise) over theoretical questions. Prospecting performance is something you observe, not something candidates tell you about.

30-60-90 day onboarding plan: the milestones that make the difference

The average SDR ramp-up time is 3.1 months (source: Bridge Group). Unstructured onboarding lengthens this period and directly erodes the ROI of the hire. Here are the concrete milestones for each phase:

  • Day 1 to Day 30 – Immersion: mastering the product and the ICP, shadowing the existing team’s calls, setting up the CRM and tools, first role plays. Goal: make the first 100 calls and send the first email sequences by the end of the phase.
  • Day 31 to Day 60 – Ramp-up: first qualifying conversations on their own, fine-tuning the pitch and objection handling with the manager, first meetings booked even if below quota. Goal: reach 50 to 60% of volume targets and secure 5 to 8 qualified meetings.
  • Day 61 to Day 90 – Full pace: multichannel sequences at cruising speed, autonomous CRM management, structured handoff to AEs, participation in pipeline retrospectives. Goal: 80 to 100% of target KPIs, qualified meeting rate > 50%.

An SDR who hasn’t reached 60% of their targets by Day 90 is rarely a profile problem: it is almost always an onboarding problem. Insufficient feedback, an unfinished script, a poorly built prospecting list or an unavailable manager. Structuring these 90 days is as much an HR investment as a sales investment.

Essential SDR tools in 2025

An SDR’s outbound marketing strategy relies on a tool stack built around four building blocks: CRM (HubSpot, Salesforce, Pipedrive), email sequencer (Lemlist, Salesloft, Outreach), data enrichment (Kaspr, Lusha, Dropcontact) and contact sourcing (LinkedIn Sales Navigator, Pharow). These tools don’t replace human qualification work – they automate repetitive tasks so the SDR can focus their energy on high-value interactions.

AI and SDRs: what’s changing in 2026

Artificial intelligence has profoundly changed the SDR’s daily work. Up to 60% of the role’s traditional tasks can now be automated: prospect research, data enrichment, drafting first versions of emails, sequenced follow-ups, post-call CRM note-taking.

This shift in tasks doesn’t eliminate the role – it refocuses it on what a human does better than an algorithm: reading between the lines of a conversation, adapting the message in real time, detecting an unspoken buying signal, building a trusted relationship over time.

In practice, the best-performing SDRs in 2026 are those who use AI to multiply their targeting and personalization capacity, while preserving the quality of human interaction in qualifying conversations. It’s not an SDR replaced by a machine: it’s an SDR whose productivity is augmented by smart tools.

A word of caution: autonomous AI SDR tools (agents that send hundreds of emails without human intervention) damage domain deliverability and produce lower reply rates than personalized sequences supervised by a human. AI-assisted personalization consistently outperforms pure automation.

FAQ – SDR Sales Development Representative

What is the difference between an SDR and a BDR?

The BDR (Business Development Representative) is exclusively outbound-focused: they identify and approach accounts that don’t yet know your brand. The SDR has a broader scope: they handle outbound prospecting AND the qualification of incoming (inbound) leads. In B2B SMEs, both roles are often merged into a single position. The distinction takes hold in larger organizations where inbound volume justifies specialization.

Which KPIs should you track for an SDR?

The core KPIs of a B2B SDR are: the number of qualified meetings handed over to the AE per month (standard target: 15 to 25 in B2B SaaS), the share of qualified meetings among all meetings booked (target: > 50%), the no-show rate (target: < 15%), and the conversion rate of handed-over meetings into AE opportunities (target: > 30%). These KPIs should be tracked by meeting source (cold call, cold email, LinkedIn, inbound) to identify the most effective channels.

What is an SDR’s salary in France?

In 2025, a junior SDR in France earns between €28,000 and €38,000 in gross annual base salary, with variable pay of €5,000 to €10,000. An experienced profile (2 to 4 years) earns between €35,000 and €48,000 base, with variable pay of up to €15,000. These ranges vary by sector (SaaS vs industry), location (Paris vs the rest of France) and company size. The total employer cost for a junior in the Paris region generally exceeds €55,000 to €60,000 per year.

How do you measure an SDR’s performance?

An SDR’s performance is measured on two complementary dimensions: activity (volume of calls, emails, LinkedIn connections – indicators of consistent effort) and conversion (qualified meeting rate, successful handoff rate to the AE – indicators of work quality). A high-performing SDR hits their conversion targets with a normal activity volume, not by making up for poor conversion with excessive volume.

Can SDR work be outsourced?

Yes, and it is an option increasingly adopted by B2B SMEs and scale-ups. Outsourcing your SDR and appointment setting to a specialized agency such as Oliverlist lets you start generating meetings within 2 to 4 weeks, with no fixed hiring cost, no turnover risk and a proven qualification process. It is particularly relevant for teams with fewer than 5 AEs, for testing a new segment, or for keeping the flow of meetings going after an in-house SDR leaves.
