You're reading a job ad for a "Business Development Manager." Base $90K, OTE $130K, uncapped commission. The duties list: generate your own leads, run discovery calls, build proposals, negotiate contracts, close the deal, then manage the account afterwards. That's four jobs. Maybe five, if the account management drags on for years. It's advertised as one.
Nobody wrote that ad to deceive you. That's what makes it worse. It's just how this industry prices ambiguity, and almost nobody says so out loud.
The titles were never really about the job
Ask ten people the difference between an SDR, an AE and a BDM and you'll get ten different answers, and most of them will be confident. That confidence is the tell. If a title genuinely described a job, people wouldn't need to guess.
Here's the honest version. An SDR (sometimes BDR) finds and qualifies conversations. An AE runs a qualified conversation to a signed contract. A BDM, in Australia, is usually both — plus whatever else the business hasn't got around to hiring for. That's not a knock on BDMs. It's a description of what the title has been asked to absorb.
The confusion isn't an accident of language. It's structural. American SaaS built the SDR/AE split because it had the volume to justify it — enough leads flowing that specialising made two people more productive than one generalist. Most Australian B2B businesses never had that volume, so they never split the role. They kept one person doing everything and gave them a title that sounded senior enough to justify the workload: Manager. Never mind that most BDMs manage no one.
What each role actually does
Strip away the branding and the differences are simple enough to fit in a table. Here's what SalesHQ tracks against real Australian pay data, not job-board folklore.
Role | Core job | Where they sit in the funnel | Typical AU total pay | Owns the close?
SDR / BDR | Finds and qualifies new conversations, books meetings for someone else to run | Top of funnel only | ~$85,000 (avg base ~$65,000 + ~$20,000 variable, Glassdoor AU) | No
AE | Takes a qualified conversation and runs it to a signed contract | Middle to bottom of funnel | ~$146,000 (avg base ~$86,000 + ~$60,000 variable, Glassdoor AU) | Yes
BDM (the Australian default) | Finds, qualifies, presents, negotiates and closes — often manages the account afterwards | The entire funnel, one person | $105,000–$125,000 package on average (SEEK AU, disclosed on job ads) | Yes, plus everything an SDR does first
Sit with that table for a second, because the number that should bother you isn't in the job description. It's in the last two columns.
An AE, whose job starts after someone else has already done the prospecting, earns an average of $146,000 in this country. A BDM, who is frequently asked to do the prospecting and the closing and the account management, earns $105,000 to $125,000. Less money, more job. Say that back to yourself.
Where they sit in the funnel — and why that's the only distinction that matters
Forget the titles for a moment and draw your funnel on a whiteboard. At the top: strangers who've never heard of you. In the middle: people having a real conversation about whether you can solve their problem. At the bottom: a signature.
An SDR's entire job is moving people from the top of that funnel into the middle, then handing them off. An AE's entire job starts in the middle and ends at the bottom. Neither role, done properly, touches the other's territory much. That's the point of splitting them — each person gets good at one motion instead of average at two.
A BDM covers the whole whiteboard alone. That's not automatically a bad structure — for a lot of businesses, it's the right one, and we'll get to when. But it means the title tells you nothing about scope. "BDM" could mean a $70K glorified appointment-setter or a $140K full-cycle closer managing seven-figure accounts. The title is doing no descriptive work at all. It's a placeholder.
What not to confuse — and the test that cuts through it
Here's a test that takes two minutes with any job ad, live or one you're about to write. Go through the duties list and tag each line: is this a top-of-funnel task (finding, qualifying, booking) or a bottom-of-funnel task (presenting, negotiating, closing, managing)?
If every line falls on one side, the title is accurate. If the list spans both — and for most Australian "BDM" ads, it does — you're not looking at one role. You're looking at two or three roles that never got separately budgeted, wearing a single job title so the business only has to make one hire and pay one salary.
That's worth sitting with, because it reframes the whole conversation. The problem with these titles was never that people are bad at defining them. It's that a vague title is cheaper than an honest one. A specific, accurate title — "Full-Cycle Account Executive, prospecting and closing" — invites a candidate to price the whole job. "Business Development Manager" invites them to price a manager, and the closing-and-prospecting part rides along for free.
Picture a fifteen-person logistics software company in Melbourne. One "BDM" on the payroll. Their week: forty cold calls, two demos, one contract redline, and an existing client asking why their invoice went up. That's an SDR's week, an AE's week, and a chunk of a customer success manager's week, stitched into one job description and one salary. Run that person's actual hours against the three roles they're covering and the hourly rate looks nothing like the number on the offer letter. Nobody sat down and decided to underpay them. The business just never separated the maths.
The part nobody says out loud
There's a body of research on this exact pattern, and it isn't specific to sales. A recent MyPerfectResume survey found 92% of workers believe companies use inflated titles to create the illusion of career growth while withholding raises. 91% said employers use title changes specifically to avoid paying more. And 15% admitted they'd personally accepted a lower salary in exchange for a more senior-sounding title on the door. Separately, a 2023 Pearl Meyer survey of more than 400 organisations found 54% were deliberately using job titles to attract talent — up 35% since 2018, and the report links the shift directly to businesses limiting real pay increases.
None of that research was written about sales specifically. It didn't need to be. "Manager" is one of the cheapest words in the English language to hand someone instead of a pay rise, and sales is one of the few functions where a title can also imply commission upside that may or may not materialise.
This is the bit that's uncomfortable to write, given who's writing it: recruiters benefit from this ambiguity too. A broad, undefined title pulls a wider pool of applicants than a precisely scoped one. It's faster to fill. It's easier to write. Nobody in that transaction — the employer writing the ad, or the agency placing the candidate — has a strong incentive to narrow it down, right up until the person hired discovers in month two that the job is three jobs and the pay was one.
When to actually hire each — briefly, because this isn't the diagnosis piece
This article isn't where you work out which role to hire first — that decision depends on your pipeline, your deal size and your cycle length, and we've mapped that properly in our guide on what sales role to hire first. But as a rule: split the role once you have enough deal volume that a dedicated closer would otherwise sit idle waiting for a dedicated prospector to feed them, and enough budget to pay for two specialists properly instead of one generalist badly. Below that volume, a single full-cycle hire — call it BDM, call it founding AE, the label barely matters — is usually the right structure. Just price it like the job it actually is, not the title on the door.
The audit, in one sentence
Before you post your next ad, or answer the next one, do this: list every duty in plain English, tag each one top-of-funnel or bottom-of-funnel, and count how many separate jobs are on that list. If it's more than one, ask yourself honestly whether the salary reflects that — or whether the title is doing the job the pay cheque should be doing.
Roughly 300 to 700 people search "SDR vs AE vs BDM" every month in Australia. Most of them aren't confused about English. They're trying to work out whether the job in front of them is what it says it is. That's not a small question. It's the first negotiation you'll ever have with an employer, and it happens before you've even applied.
If you're not sure whether your own role — SDR, AE or BDM — is priced to match what it actually asks of you, SalesHQ's Sales Salary Guide benchmarks pay against real scope, role by role, across the Australian market.
