BDR vs SDR vs AE - What Is The Difference And Which One Should You Target

The Sales Hierarchy In A Typical SaaS Company

Before diving into specific roles it helps to understand how a sales organization is typically structured at a SaaS company.

At the foundation you have Business Development Representatives and Sales Development Representatives. These are entry to mid level roles responsible for generating pipeline. Above them sit Account Executives who are responsible for closing new business. Senior Account Executives handle larger deals or more complex accounts. Above the AE level you have Sales Managers, Directors of Sales and VP of Sales. At the top sits the Chief Revenue Officer.

The most common entry point into this hierarchy for someone new to tech sales is the BDR or SDR role. The most common next step after 12 to 18 months of strong performance as a BDR is a promotion to Account Executive.

BDR vs SDR - Is There Actually A Difference

Technically yes. In practice at most companies not really.

The original distinction was this. A Business Development Representative focused on outbound prospecting. They researched target accounts, identified decision makers and initiated contact through cold calls, cold emails and LinkedIn outreach with the goal of booking meetings for Account Executives.

A Sales Development Representative, in the original definition, focused on inbound lead qualification. They followed up on leads generated by marketing, qualified them against specific criteria and passed the qualified ones to Account Executives.

In practice the vast majority of companies today use BDR and SDR interchangeably to describe a role that does some combination of both. When you see a BDR or SDR posting you should assume it involves outbound prospecting, some inbound follow up and meeting booking for AEs unless the description specifically clarifies otherwise.

When you are applying for these roles the title itself matters less than understanding what the specific company means by it. Read the responsibilities section carefully and look for language around outbound versus inbound, cold outreach versus lead follow up.

What A BDR Actually Does Day To Day

A typical day for a BDR at a SaaS company looks something like this.

The morning usually starts with reviewing a sequence of target accounts and personalizing outreach for the ones at the top of the priority list. This involves researching the company, identifying recent news or triggers that make the outreach relevant and writing or adjusting email templates to reflect that context.

From there the day involves a combination of cold calls, email follow ups and LinkedIn messages. Most BDRs work within a structured sequence tool like Outreach, Salesloft or HubSpot Sequences that automates the timing and tracking of outreach steps while leaving the content personalization to the rep.

Meetings booked is the primary metric most BDRs are measured against. The number of qualified discovery calls they schedule for Account Executives per week or per month determines whether they are hitting their targets. Supporting metrics typically include daily call volume, email open rates, reply rates and show rates on booked meetings.

The BDR role is demanding. The rejection rate is high. The daily activity requirements are non trivial. And the learning curve in the first 90 days is steep. It is also one of the most accelerated development environments available in any profession. A BDR who performs well for 12 to 18 months comes out the other side with skills in prospecting, objection handling, pipeline management and commercial communication that take years to develop in most other roles.

What An AE Actually Does Day To Day

An Account Executive is responsible for taking opportunities from qualified discovery call through to closed deal. Where the BDR generates pipeline the AE converts it.

A typical AE day involves a combination of discovery calls with new prospects, product demonstrations, proposal writing, negotiation conversations, internal deal reviews and pipeline management in the CRM. At the AE level you are managing multiple deals at different stages simultaneously and the skill of knowing where to spend your time is as important as any individual selling skill.

AEs are measured primarily on revenue closed and quota attainment. A typical SaaS AE quota ranges from $500,000 to over $2,000,000 in annual recurring revenue depending on the company's deal size, market and sales motion.

The AE role requires a deeper set of skills than the BDR role. Discovery, demonstration, proposal, negotiation, closing and account management all come into play. Most strong AEs spent time as BDRs first and carry the prospecting instincts from that experience into their closing role.

SMB vs Mid Market vs Enterprise - Which Should You Target

Most SaaS companies segment their sales organization by deal size and company type. SMB refers to small and medium businesses. Mid Market refers to companies in the middle of the size spectrum typically defined by employee count or revenue. Enterprise refers to the largest companies, often those with more than 1,000 employees or significant revenue.

For someone breaking into tech sales the SMB or Mid Market BDR role is almost always the right starting point regardless of ambition. Here is why.

SMB and Mid Market roles have faster sales cycles, more manageable deal complexity and more activity volume. This means you develop your skills faster. You make more calls, send more emails, book more meetings and handle more objections in a shorter period of time than you would in an Enterprise role where a single deal might take 6 to 12 months to close.

Enterprise sales is where the biggest compensation packages live. An Enterprise AE at a major SaaS company can earn $300,000 or more in total compensation. But getting there requires a foundation built at the SMB and Mid Market level first. The candidates who try to skip that foundation and go straight to Enterprise without the relevant experience almost always struggle.

Which Role Should You Target Based On Your Background

The right entry point depends on where you are coming from.

Recent graduate with no professional sales experience: The SMB or Mid Market BDR role is your target. It is the most accessible entry point and the one most frequently open to candidates without direct sales background. Focus your search here, build your foundation and move from there.

Professional transitioning from another field: The answer depends on how much of your previous experience maps to sales competencies. Someone coming from account management, customer success, recruitment or any role that involved building relationships, handling objections and driving outcomes has more transferable experience than they often realize. These candidates can often position themselves for Mid Market BDR roles or occasionally for SMB AE roles at smaller companies depending on their background.

Experienced sales professional from outside tech: You have the selling skills. What you often lack is the specific vocabulary, metrics awareness and tech industry context that SaaS hiring managers look for. Bridging that gap through targeted preparation is usually the differentiating factor between getting the interviews and converting them.

The Titles That Are Worth Knowing

Beyond BDR, SDR and AE there are a handful of other titles you will encounter in your tech sales job search that are worth understanding.

Account Manager typically refers to a post sale role responsible for managing existing customer relationships, driving renewals and identifying expansion opportunities within current accounts. It is sometimes used interchangeably with AE at smaller companies but at larger organizations it is a distinct role focused on customer retention rather than new business acquisition.

Inside Sales Representative is a title more commonly used at companies that have not yet fully adopted the BDR and AE model. It typically describes a full cycle sales role where the rep handles both prospecting and closing. These roles can be excellent opportunities for someone who wants to develop a complete sales skill set quickly.

Sales Engineer or Solutions Engineer is a technical role that works alongside AEs during the demonstration and proposal stages of more complex deals. This is not a good entry point for someone without a technical background but it is worth knowing it exists as a future path if you develop deep product expertise over time.

The Bottom Line

The title on a job posting is less important than understanding what the role actually involves, what you will be measured on and whether your background gives you a credible story for that specific company and team. The most important decision is not BDR versus SDR. It is choosing the right company, the right market segment and the right preparation for the specific role you are targeting.

The candidates who do that work before they apply consistently outperform those who spray applications broadly and hope something sticks.
