SDR and BDR titles are not standardized. Some companies use sales development representative (SDR) for inbound qualification and business development representative (BDR) for outbound prospecting. Others use either title for a mix of both. For a SaaS hiring decision, define where demand comes from, what the rep owns, and who takes over next before choosing the title.
The title matters less than the work you need done. Before hiring an SDR or BDR, identify where your sales team needs support: qualifying inbound enquiries, opening conversations with target accounts, or progressing qualified opportunities. That tells you whether to hire for sales development or add closing capacity.
This guide explains the difference between SDR and BDR roles, compares their responsibilities, and shows how inbound and outbound sales development fit different sales models. It also helps you decide which role to hire first, when an account executive is the better choice, and how to set clear expectations before recruiting.
SDR vs BDR: what is the difference?
Both roles support the early sales cycle: identifying potential customers, assessing fit, building conversations, and passing qualified opportunities to an account executive (AE) or another designated closer. The exact responsibilities depend on the employer.
GitLab’s sales-development handbook describes an inbound-focused SDR team and an outbound-focused BDR team. In contrast, Salesforce’s sales careers page describes SDRs and BDRs together as working with inbound and outbound leads. These are company-specific examples, not universal job definitions.
Write “inbound qualification,” “outbound prospecting,” or the agreed mix alongside the title in your hiring brief. Here, BDR means business development representative, not business development manager; do not assume the two jobs have the same scope.
Compare SDR and BDR responsibilities by sales motion
Use this framework to define the work. Either title may be used for either motion.
| Hiring decision | Inbound qualification | Outbound prospecting |
|---|---|---|
| Starting point | A prospect has engaged through a defined source | The team selects an account and initiates contact |
| Core responsibilities | Prioritize enquiries, clarify needs and assess fit | Research accounts, establish relevance and develop interest |
| Evidence to assess | Queue prioritization, listening and accurate qualification | Account selection, relevant messaging and thoughtful follow-up |
| Handoff | Buyer context, fit evidence and an agreed next step | Engagement history, fit evidence and an agreed next step |
| Quality measures | Accepted handoffs, rejection reasons and progression | Accepted opportunities, account relevance and progression |
| Closing ownership | AE or designated closer unless explicitly included | AE or designated closer unless explicitly included |
Inbound does not mean every enquiry is sales-ready. A demo request, event attendee and content download may need different follow-up. Define what each source tells the rep and which enquiries deserve priority.
Outbound requires more than a contact list. Specify which accounts to approach, which buyer problem to explore and why the conversation could be relevant. Amplemarket’s account of its own BD team illustrates research, messaging and handoff work within an outbound role; it is not a benchmark for every team.
Both motions require judgment. An inbound rep needs to recognize poor fit despite apparent enthusiasm. An outbound rep needs to explain account relevance without presenting an assumed business problem as a fact.
Should your SaaS company hire an SDR or BDR first?
Hire for inbound qualification first when suitable demand needs handling; hire for outbound prospecting first when a defined market needs more account coverage. Some employers call these roles SDR and BDR respectively, but the assignment matters more than the label. If the sales approach is still unproven or closing capacity is the constraint, neither development role may be the right next hire.
Think of your company’s stage in terms of sales readiness, not a fixed Seed, Series A, Series B or annual recurring revenue (ARR) threshold. Check whether the proposed hire has enough suitable work, support and receiving-seller capacity to succeed. Budget for the approved employment package, tools and management time; use your own funnel evidence to judge the headcount case.
| Sales readiness or current bottleneck | Scope to consider first | Check before recruiting |
|---|---|---|
| Founder-led validation: you are still learning who buys and why | Continue founder-led learning or define an explicitly experimental sales role | What is proven, what remains uncertain and who will own the learning |
| Repeatable inbound demand: suitable enquiries are going unworked | Inbound qualification | Source quality, workload, coverage and AE handoff capacity |
| Defined outbound motion: a clear target market has too little account coverage | Outbound prospecting | Usable accounts, evidence of buyer interest, messaging and coaching |
| You need both inbound follow-up and outbound prospecting | An explicitly scoped mixed development role | Priority rules, protected prospecting time and realistic combined workload |
| Closing capacity: qualified opportunities are waiting or stall after handoff | AE capacity or sales-process improvement | Whether the constraint is capacity, discovery, product evaluation or commercial progression |
These conditions can overlap; they are not mandatory steps in a sequence. Diagnose the gap you need this hire to address.
During founder-led validation, define the sales approach first
If you cannot yet name the buyer, explain the offer or define the next step after qualification, document the missing decision and its owner. Neither job title resolves those gaps. Continue founder-led learning or explicitly recruit for a broader experimental assignment, with the support and capability that work requires.
With repeatable inbound demand, consider inbound qualification first
Review recent enquiries by source, customer fit and handling. Are suitable buyers waiting because nobody can respond, or are most enquiries outside your target market?
Consider an inbound hire when qualification is a genuine workload with a clear next owner. Resolve broken routing or disputed acceptance criteria before treating them as a new employee’s performance problem.
Illustrative scenario: A fictional SaaS team has suitable demo requests waiting while AEs manage existing opportunities. An inbound qualification role could address the gap, provided the AEs can accept the resulting handoffs.
With a defined outbound motion, consider outbound prospecting first
Check that someone can explain the target accounts, buyer problem, reason to engage, and likely next step. Review actual conversations as well as account-list size.
A development rep can execute and improve a defined approach. If the assignment also includes discovering the market and building the process, say so and assess that broader capability. Do not recruit for a narrow execution role and then judge the hire on an undefined market-development task.
Illustrative scenario: A fictional team has a clear buyer profile, a relevant account list and an AE who has converted outbound conversations. An outbound BDR could extend coverage with agreed coaching and handoff support.
Define priorities if one person will do both
A mixed role needs explicit rules for what happens when inbound follow-up competes with outbound work. Agree which enquiries take priority, when the rep prospects and how the manager will adjust expectations when the workload changes.
Assess candidates against both assignments. Avoid setting two full workloads and assuming one person can absorb them simply because both sit under sales development.
When closing capacity is the constraint, consider an AE or full-cycle seller
If qualified opportunities are waiting for discovery, demonstrations or commercial progression, review closing capacity before adding more development headcount. A full-cycle seller may fit an assignment spanning prospecting through closing, but that broader scope needs its own assessment, support and success measures.
Illustrative scenario: A fictional founder has more qualified discovery calls than they can handle but little unworked inbound demand. Another qualification hire would not address the immediate bottleneck. The guide to hiring your first AE explores that distinct hiring decision.
Name the manager or coach and, where the role hands opportunities over, the receiving seller. Use your workload, deal complexity and management capacity to set the scope.
Turn the decision into a clear hiring brief
Before sourcing candidates, agree these details with the hiring manager and the receiving seller:
- Customer and territory: Buyer roles, company segment, target market and exclusions.
- Sales motion: Inbound sources, outbound accounts or the expected mix, with priority rules.
- Ownership: Stages the rep owns, qualification evidence required and the person accepting each handoff.
- Support: Named coach, product training, usable data, systems and access to the receiving seller.
- Success measures: Outcomes, quality standards, review dates and dependencies outside the rep’s control.
- Approved package and work arrangement: Location, working hours, compensation structure and employment terms.
For US and Australian hiring, distinguish the employee’s location from the customer territory. Specify the time-zone overlap, eligible work locations and whether the rep serves one market or both. State package amounts in USD or AUD as appropriate, and clarify Australian superannuation treatment with the relevant HR owner. These details belong in the brief; neither “SDR” nor “BDR” answers them.
Use the same scope to brief internal recruiters or seek sales recruitment support. Compare candidates’ actual responsibilities and evidence, not just their previous job titles.
Set success measures before the hire starts
Pair output with quality. For example, review accepted handoffs alongside rejection reasons, and qualified opportunities alongside their subsequent progression. Agree what qualifies, who accepts it, and who follows up after a postponed or missed meeting.
Keep activity measures diagnostic. Call or email counts can explain execution, but they don’t show whether you contacted the right buyers or whether a credible opportunity exists. Track downstream outcomes without treating closed revenue as entirely controlled by a rep who does not own the close.
Set targets using your own lead supply, account coverage, conversion history and available support. If that evidence is limited, make the assumptions explicit and schedule a review rather than copying another company’s quota.
Use 30, 60 and 90 days as review points, not guaranteed ramp times:
- Day 30: Review buyer and product knowledge, a motion-specific work sample and readiness for supervised work.
- Day 60: Review live execution, handoff quality and progress against the agreed outcome targets.
- Day 90: Review consistency, independence and any changes needed to targets, support or scope.
For each review, record the manager responsible, the evidence, the next action and the next review date. Separate insufficient lead supply or usable accounts from the rep’s execution.
Assess candidates against the work you need done
Use a short, fictional exercise with consistent background information and clear assessment criteria. Offer an appropriate route to request adjustments.
For an inbound role, give candidates enquiries with different levels of intent and fit. Ask them to prioritize the queue, conduct a qualification role-play, and write a handoff note.
For an outbound role, provide a small fictional account set. Ask which account they would approach, why it is relevant, what they would say, and how they would handle an objection.
Score judgment, communication, qualification, and handoff clarity. Give brief feedback and allow a revision to see how the candidate applies it. Do not use the exercise as unpaid prospecting or request confidential information from a previous employer.

SDR vs BDR FAQs
Are SDR and BDR the same job?
They can overlap. Some companies distinguish inbound SDRs from outbound BDRs; others use the titles differently. Check the lead sources, responsibilities, qualification expectations, and handoff ownership in the job brief.
Is a BDR more senior than an SDR?
Not necessarily. A company may place the titles at different levels, but neither title establishes a universal seniority ranking. Assess the scope, complexity, independence, and relevant experience required for your role.
Should a startup hire an SDR or BDR first?
Base the choice on sales readiness rather than funding stage. Consider inbound qualification when suitable demand needs handling, or outbound prospecting when a defined market needs more coverage. Both need coaching and a capable receiving seller. If closing capacity or an unproven sales approach is the constraint, address that instead.
Can an SDR or BDR also close deals?
Yes, if closing is deliberately part of the assignment. Make that ownership explicit and assess the broader skills, workload and support required. Do not assume closing is included in a development title.
Can one person handle inbound and outbound sales development?
It can be a defined mixed role. Agree priorities, capacity and separate quality measures for each motion, then review whether the combined workload remains realistic.
