Sales Development Representative (SDR) and Business Development Representatives (BDR) are two pivotal roles in sales. Both of them are responsible for bringing business or converting people into customers. However, their focus, targets, strategies, outreach approach, and goals greatly differ.
For a business, it’s crucial to understand the difference between them to strengthen the sales cycle and bring more conversions. But the issue is that these roles are so similar that people often consider them the same.
Here we’ll dive deep into the responsibilities, focus, goals, and every detail related to these representatives. We’ll discuss SDR vs BDR and compare them to help understand the difference and the nitty-gritty.
Part 1: What is SDR (Sales Development Representative)?
A Sales Development Representative (SDR) is a role in the sales cycle that focuses on inbound leads. This means when a potential customer reaches out to the businesses through various channels, such as a website, social media, or email showing his interest in the business, the SDR takes over and engages with the lead.
The primary goal is to find the leads that can convert into customers and hand them off to the Account Executives (AEs). They build a strong relationship with the customers and convince them to buy the product, service, etc. They schedule a meeting with the AEs for the closure of the deal. It makes the time of AEs more productive and reduces their workload.
Part 2: What is BDR (Business Development Representative)?
A Business Development Representative (BDR) is a similar role, but it focuses on bringing in new business or clients by targeting outbound leads. They help businesses find new opportunities and connect with potential customers who have never interacted with the company before.
They target new customers, reach out to them, understand their pain points, and propose solutions. They tell customers about the product or service and convince them to buy the product. They also schedule an introductory meeting with the AEs or senior representatives.
Part 3: SDR vs. BDR: Key Differences
SDR and BDR might sound similar to beginners, but there are some key differences that help distinguish both roles.
| SDR | BDR | |
|---|---|---|
| Primary Focus | Qualifying inbound leads generated through marketing | Generating outbound leads and finding new opportunities |
| Lead Source | Warms leads through contact forms, social media, etc. | Cold leads generated by cold reaching out to new contacts |
| Lead Volume | High lead volume | Low lead volume but high-value leads |
| Outreach | Responding outreach after an inquiry is received | Proactive outreach to find new customers through cold calls, cold emails, etc. |
| Relationship | Initial contact and qualification | Building deep relationships |
1Primary Focus
The focus of both the SDRs and BDRs is completely different.
SDRs are responsible for inbound leads—those that have reached the business because of marketing efforts. There are multiple sources, but the customers initiate the conversation or show their interest.
Once they get a message, email, or inquiry from a customer, SDRs reach out to understand their pain points or needs. They figure out whether the lead is beneficial or not and assess the likelihood of conversion. If the lead is interested in the business or service, they transfer the conversation or schedule a meeting with the AEs.
On the other hand, the focus of BDRs is to look for people who might be interested in the business. They try different channels and methods to find people likely to convert.
They reach out to customers first, pitch the product or service, explain the benefits, and try to generate interest. Their main focus is outbound leads—people who have never interacted with the business before.
BDRs find new opportunities for the business. They engage with these prospects and, once they see a likelihood of conversion, schedule a meeting with the AEs or seniors. They are also responsible for identifying new markets, businesses, industries, and customer segments, making them the backbone of scaling or expansion.
2Lead Source
The lead sources of SDRs and BDRs are also different.
SDRs work with inbound leads. The customer reaches out through paid advertisements, search engines, social media posts, word of mouth, etc.
The common sources are websites, forms, eBooks, case studies, webinars, event signups, referrals, chatbots, etc. In all these cases, the customer reaches out on its own. That said, the customer is already curious or interested in the product or service. This kind of lead is called inbound lead.
In contrast, BDRs work on outbound leads. They need to find leads on their own. For that, they do cold calls, cold emails, etc. They look for the customer who could be interested in the product. They research the market, target audience, businesses, etc.
They get their leads from emails, calls, LinkedIn, social media, etc. Other than that, networking and referrals are also excellent sources.
3Outreach
SDRs get leads through marketing, but their responsibility is to engage with them and determine whether they are a good fit for the business. They filter out leads so the sales team can focus on those that matter most. Often, they assess leads based on specific criteria and score their interest or likelihood of conversion.
When a customer shows interest or curiosity, the representative reaches out through the provided email, phone number, social ID, etc. They must follow up in a timely manner and gather the necessary information before handing the lead off to the AEs.
BDRs are responsible for generating new opportunities by reaching out to people who haven't interacted with the business before. They look for ways to connect—finding phone numbers, emails, social media accounts, networks, and other channels to make contact. Their goal is to make potential customers aware of the product or service and spark interest.
Representatives need to conduct thorough research and put in significant effort to bring new customers on board. As a result, their outreach methods and channels differ from those of SDRs.
4Lead Volume
When talking about SDRs, the lead volume is massive due to ongoing marketing campaigns. The more effort and money spent on marketing, the more leads they receive.
People reach out through various methods, including contact forms, chatbots, social media, email, and calls. Therefore, the volume is very high. However, not all of these leads are convertible—most do not proceed to the next stage of the sales process.
SDRs need to spend a lot of time managing and filtering leads to identify those more likely to convert.
On the other hand, BDRs handle fewer leads, but the quality is typically higher. The leads they gather have greater potential and value.
They focus on finding the right people for the product or service, targeting prospects with similar interests, backgrounds, or pain points. Each lead requires more time and effort, as BDRs must understand individual needs and effectively introduce the product or service.
5Relationship Building
When people show interest in a product or service, SDRs lead the initial conversation. They are responsible for handling leads, identifying qualified ones for the AEs, providing initial information, and building basic trust. Once the lead is ready, they pass it to the AEs, who then focus on deepening the relationship and closing the deal.
BDRs, on the other hand, focus their efforts on building strong relationships from the beginning. After reaching out, they work to understand the lead's needs and tailor their approach accordingly, aiming to offer personalized solutions and real value.
Through frequent follow-ups and meaningful conversations, BDRs gradually build trust and turn cold outreach into warm, engaged prospects. Before handing off to AEs, they ensure a strong foundation is in place, which is why BDR-generated leads often show a higher conversion rate.
SDR vs BDR
In short, while SDRs focus on qualifying inbound leads driven by marketing, BDRs proactively reach out to outbound leads, building relationships from scratch to create new business opportunities. This clear division helps streamline the sales process and improve overall efficiency.
Part 4: Building a Sales Team That Fits Your Growth Strategy
