SDR vs. BDR: Roles, Metrics, and Marketing Handoffs

Marketing and inside sales alignment means more than passing contact records. Agree on the target customer, the meaning of an inquiry, ownership, next actions and return conditions. The customer should be able to continue evaluating without repeatedly explaining the same situation.

SDR and BDR titles vary across organizations. One common arrangement assigns inbound response to SDRs and selected-account development to BDRs. Neither title inherently determines customer size or the employee’s seniority.

Define responsibilities before titles

Example role	Starting point	Main work	Useful evidence
Marketing	Customer problems and acquisition	Audience, message, education and collection	Suitable contacts and subsequent progress
SDR	Incoming interest	Confirm purpose, fit and next conversation	Handling quality and accepted cases
BDR	Selected accounts	Research, relevant outreach and discovery	Fit and a real evaluation opportunity
Closing sales	An agreed commercial discussion	Evaluation, proposal and terms	Progress, wins and economics

A small team can assign several roles to one person, while still separating the responsibilities. The MQL and SQL guide provides a companion lifecycle example.

Respect the difference between a request and a download

An explicit request to evaluate a product is not equivalent to downloading introductory material. Treating every download as a sales-meeting request creates mismatched expectations. Review what the person was told, their communication preferences and their current problem before proposing a meeting.

For account development, prepare evidence for the account hypothesis and a question that can confirm it. A problem inferred from public information remains a hypothesis until verified with the organization.

Specify handoff and return rules

Item	Agreement needed
Scope	Which customer and operational problem are supported?
Minimum context	Stated request, source, contact conditions and unknowns
Acceptance	Who decides, within how many business days?
Routing	Absence, duplication and existing-customer cases
Return	Reason and condition for reconsideration
Stop	Refusal, suppression or out-of-scope closure

For a fictional workflow, an explicit evaluation request receives an assigned owner by the next business day. Before arranging a meeting, the owner confirms its purpose and participants. Set targets according to staffing and operating hours, with cover when someone is unavailable. An acknowledgment email is distinct from substantive review.

Example qualification brief

Case A-101: a prospect requested a reporting guide and then asked for advice. Their stated problem is monthly consolidation handled by one employee. They want to understand what could change in the existing workflow. Unknowns include contributors, devices and budget. The SDR will confirm the purpose and, if useful, arrange a discussion with implementation support by the next business day.

This is fictional. Do not fill the same fields from open counts or anonymous behavior alone. Record unknowns honestly and avoid interrogating a prospect for every possible field before providing value.

Review quality and capacity alongside volume

Metric	Definition	Diagnostic purpose
Initial response time	Receipt to substantive first response	Account for business hours and automatic replies
Acceptance rate	Accepted cases ÷ handed-off cases	Check fit agreement
Meeting completion	Held ÷ agreed meetings	Review cancellations and postponements
Opportunity rate	Opportunities ÷ held meetings	Assess problem and account suitability
Handling effort	Recorded staff time	Check operating sustainability

Compare the same cohort over equivalent follow-up periods. Meeting count alone may reward unnecessary meetings. Capture acceptance and rejection reasons as well as rates.

A fictional 30-minute weekly agenda allocates five minutes to unhandled cases, ten to returns, ten to customer learning and five to next actions. End with the exact form, asset, message or definition to change, plus an owner and deadline. That makes alignment observable in the workflow rather than a recurring request for better cooperation.
