SDR and BDR are the two most common titles for the role that opens pipeline at the top of the funnel. At many B2B SaaS companies the two titles are used as synonyms. At others, they map to a real split between inbound and outbound work. The confusion is old enough that hiring managers, recruiters, and reps themselves often disagree on what each title means.
The shortest answer is that the title split is mostly historical, but the work split inside teams is real. This guide walks through where the labels diverge, where they overlap, and how to decide which one fits your pipeline motion.
The Sales Development Representative title popularized at Salesforce in the mid-2000s referred to inbound qualification: triaging marketing-sourced leads, running first-call discovery, and routing qualified opportunities to account executives. The Business Development Representative title, used earlier at companies like Oracle and IBM, referred to outbound prospecting: cold outreach into named accounts to source new logos.
Bridge Group SDR surveys from the past decade show the split has blurred. Roughly two-thirds of teams use one of the titles for both functions, with the choice driven by founder preference rather than scope. The remaining third still uses SDR for inbound and BDR for outbound, with separate teams and separate managers.
Inbound development reps own the response to marketing-sourced leads, content downloads, demo requests, and product signups. The work is paced by the volume of inbound the marketing team produces. A typical inbound rep handles 40 to 80 leads per week, runs a short first-call discovery, and books qualified meetings for an account executive.
The metrics that matter are speed to lead, qualified meeting rate, and downstream pipeline conversion. The best inbound reps live in the inbound queue, are measured on response time in minutes, and rarely run multi-touch sequences. The work overlaps with the B2B sellers directory and the practitioner content at The Seller Report.
Outbound development reps own cold prospecting into named accounts. The work is paced by the size of the territory and the depth of the named account list. A typical outbound rep runs sequences against 80 to 200 accounts at any time, builds out contacts across each account, and books first meetings with new logos.
The metrics that matter are accounts touched, meetings sourced, and pipeline created. Modern outbound teams also track quality signals like account fit, multi-thread depth, and reply rates. The role increasingly overlaps with GTM engineers on the tooling side and with AI SDR systems on the automation side, with platform data tracked at GTME Pulse.
Bridge Group and RepVue data converge on similar comp bands for both titles when work is held constant. On-target earnings for a first-year SDR or BDR at a venture-backed B2B SaaS company typically sit between 60 and 85 thousand US dollars, with a 65 to 75 percent base and the rest tied to meetings or qualified opportunities. Senior reps approaching promotion to AE earn closer to the top of that band.
The pay band itself does not move much by title. Where comp diverges is by motion: enterprise outbound roles tend to pay 5 to 15 percent higher than inbound SMB roles at the same company, because the cycle is longer and the named account work is harder to learn. The breakdown is tracked in detail at The Seller Report.
Both titles most often report into a manager of sales development, who in turn reports to a VP Sales, head of sales development, or VP Marketing depending on the company. Reporting into marketing tends to correlate with an inbound-heavy motion. Reporting into sales tends to correlate with an outbound-heavy motion. Reporting into RevOps is rare and usually a transitional setup at companies that have just hired their first RevOps lead.
Bridge Group benchmarks place the SDR-to-AE ratio in B2B SaaS in a 1:2 to 1:3 band for most companies. Enterprise-led motions run closer to 1:1, with one or two named-account BDRs per enterprise AE. High-volume SMB motions run closer to 1:4, with a single inbound rep covering multiple closers.
The ratio matters more than the title. A team with three SDRs and one AE in a high-velocity SMB motion looks different from a team with one BDR and one AE in an enterprise motion, regardless of which label the team uses. The B2B SaaS GTM org chart guide walks through how the ratios shift by ARR stage.
The next step from either title is AE in roughly 70 percent of cases, based on a mix of Bridge Group and RepVue surveys. Other paths include moves into sales enablement, marketing operations, customer success, or RevOps. The sellers directory and sales enablement directory cover the resources for each of those moves.
Tenure to promotion is more predictive than title. The median time from SDR or BDR to AE sits around 18 to 24 months at well-managed teams, with the top quartile promoting at 12 to 15 months and the bottom quartile lingering past 30 months. The SDR to AE promotion guide covers the signals to use.
If the role you are hiring for is primarily inbound, calling it SDR aligns with industry convention and makes the JD easier to read for candidates. If the role is primarily outbound, BDR is the more conventional label, especially for enterprise named-account work. If the role does both, pick the title that matches the dominant motion and document the scope in the job description so candidates know what they are signing up for.
The mistake to avoid is using the title split as a signaling tool to imply seniority. Some teams use BDR to mean a more senior SDR, which only works inside the company and confuses external candidates. If you need a senior tier, create a Senior SDR or Senior BDR title with its own scorecard, comp band, and promotion criteria.
Three patterns recur in the hiring reviews published by Pavilion and Bridge Group. The first is splitting inbound and outbound across two titles without splitting the management, which produces a manager who only knows one half of the job well. The second is pairing one SDR or BDR with multiple AEs across very different segments, which spreads the rep too thin to specialize. The third is over-investing in outbound headcount before the inbound funnel is converting, which masks weak marketing with raw activity.
The fix to all three is to write the scope before the title. The label can be SDR, BDR, or something else. What matters is whether the rep, the manager, and the AE all describe the role the same way on day 60.
Neither is senior in industry convention. Some companies use BDR to imply seniority over SDR, but the practice is inconsistent and confuses external candidates. If you need a senior tier, create a Senior SDR or Senior BDR with its own scorecard rather than relying on the title split.
BDR is the more common label for outbound named-account prospecting, especially at enterprise B2B companies. SDR is more common for inbound qualification work, though about two-thirds of teams use a single title for both motions.
At the same company and same motion, comp bands are similar. Where pay diverges is by segment: enterprise outbound roles tend to pay 5 to 15 percent more than inbound SMB roles because the cycle is longer and the prospecting work is harder to learn.
Bridge Group benchmarks put the ratio in a 1:2 to 1:3 band at most B2B SaaS companies. Enterprise motions run closer to 1:1 and high-volume SMB motions run closer to 1:4. The ratio is more about the motion than the title.
Both patterns are common. Reporting into marketing correlates with inbound-heavy motions. Reporting into sales correlates with outbound-heavy motions. The function lives well in either place as long as the manager owns the metrics that match the team's actual work.
