What Is an SDR? Role, Metrics, and When to Outsource

An SDR (sales development representative) is the person who prospects, contacts and qualifies potential customers, then books meetings for the sales team that closes the deal.

What an SDR does day to day

An SDR owns the top of the sales funnel. The job is to turn a target account list into booked conversations, so account executives can spend their time on live deals instead of prospecting.

01 Research target accounts and the right decision-makers inside them
02 Run outreach across email, LinkedIn and phone
03 Handle replies and objections, and qualify interest
04 Book meetings and hand them to the closer with context

SDR vs BDR

The titles are used differently from company to company. A common split is that SDRs work inbound leads and smaller accounts, while BDRs run outbound prospecting into larger target accounts. In many teams the two roles overlap, so check the job description rather than the title.

How SDR performance is measured

The metrics that matter are the ones tied to pipeline, not activity for its own sake.

- Qualified meetings booked per month
- Reply rate and positive reply rate
- Meeting show rate
- Pipeline created from the meetings booked

In-house vs outsourced SDRs

An in-house SDR knows your product deeply and sits inside your team, but you carry recruiting, training, management and the ramp time before they produce meetings. An outsourced SDR team arrives trained and managed, with the tooling already in place, but needs a clear brief on your offer and ideal customer.

When outsourcing makes sense

Outsourcing tends to fit when you want pipeline faster than a hire can ramp, when you are testing a new market before committing headcount, or when your founders and closers are still doing the prospecting themselves. If you want a dedicated rep without the hiring and management overhead, that is exactly what our outsourced SDR service covers.
