Quick definition

SDR stands for Sales Development Representative and BDR stands for Business Development Representative. Both are entry-level sales roles that qualify potential customers before handing them to a closer. SDRs typically work inbound leads who've already shown interest, while BDRs typically prospect cold, outbound audiences. Many companies use the titles interchangeably.

How it varies across Australia

How Australian companies split the SDR and BDR function varies by company size and stage. Early-stage teams usually collapse both into one hybrid role, while scaled B2B teams tend to separate inbound qualification from outbound prospecting once pipeline volume justifies it.

The two roles side by side

Sales Development Representative(SDR)

Qualifies inbound leads who already engaged, like a demo request or content download.

Works warm demand

Business Development Representative(BDR)

Prospects outbound into a target account list that hasn't engaged yet.

What it actually means

Picture a restaurant with two front-of-house jobs. One person greets guests who already booked a table. The other stands on the street handing out flyers to people who've never heard of the place. Both jobs involve talking to strangers and both feed the same kitchen, but the skill and the mindset are different. That's roughly the split between SDR and BDR.

SDRs typically qualify inbound leads, which is to say people who filled out a form, requested a demo or downloaded something. Their job is triage. Is this person a real fit for our ideal customer profile (ICP), and are they ready for a conversation with a closer? A qualified inbound lead usually gets labelled an marketing-qualified lead (MQL) before it reaches the SDR, and a sales-qualified lead (SQL) once the SDR confirms it's worth pursuing.

BDRs typically work outbound, which means cold calling, cold emailing and building pipeline from accounts that haven't shown any interest yet. Their job is generation, not triage. They're creating the top of the pipeline rather than filtering what's already flowing in.

In practice, the titles blur constantly. Plenty of companies call every prospecting role SDR regardless of the source of the lead, and plenty call every qualifying role BDR. Ask about the lead source and the comp plan before you trust the title.

The job title tells you almost nothing. The comp plan and the source of the leads tell you everything.

How it shows up

The distinction shows up in the comp plan first. SDRs are usually measured on meetings booked and MQL-to-SQL conversion rate. BDRs are usually measured on outbound activity volume and cold pipeline generated. It also shows up in how the CRM routes leads. Inbound form fills route to SDRs, purchased or scraped account lists route to BDRs. If both roles pull from the same queue with the same targets, the title split is decorative rather than functional.

The Australian context

Australia's smaller B2B talent pool means many companies can't justify hiring separate SDR and BDR functions the way a larger US SaaS business would. It's common to see a single junior sales hire doing both jobs under one title, often SDR by default, until pipeline volume grows enough to warrant splitting the function. Job ads borrowed straight from US templates sometimes create a mismatch between the title and the actual day-to-day work expected of the hire.

Where people get this wrong

Hiring for the title instead of the actual workload.A candidate who's excellent at qualifying warm inbound leads may struggle badly at cold outbound prospecting, and vice versa. The skills don't transfer as cleanly as the job titles suggest.

Measuring both roles against the same targets.Outbound activity takes longer to convert and has a lower response rate than inbound follow-up. Applying identical quotas to both roles sets one of them up to fail regardless of effort.

Assuming the split scales linearly with headcount.Splitting SDR and BDR too early creates two half-loaded roles instead of one fully-loaded one. Wait until pipeline volume genuinely can't be handled by a single hybrid rep.

Common questions

Is SDR or BDR the more senior role?

Neither is inherently senior. Both are typically entry-level sales roles that sit before an account executive or closer in the pipeline. Seniority depends on the company's structure, not the title itself.

Can one person do both SDR and BDR work?

Yes, and many smaller companies structure it this way. A hybrid role handling both inbound qualification and outbound prospecting is common until lead volume justifies splitting the function into two dedicated roles.

Which role should a startup hire first?

Most early-stage companies hire a hybrid rep who can do both, then split into dedicated SDR and BDR functions once inbound lead volume and outbound target account lists both grow large enough to need full-time attention on each.

Do SDR and BDR always report to the same manager?

Usually yes, both typically sit under sales development or sales operations leadership. Some larger organisations separate them under different managers if outbound and inbound strategy are run as distinct functions with different targets.
