The idea, at a glance

Compare accepted outcomes, not activity

  1. PreparationAI drafts; a seller verifies
  2. ConversationA human interprets buyer intent
  3. EvaluationCost per accepted opportunity
Include software, data, supervision and salaries in the comparison.

Use AI for research, enrichment, routing and draft generation; use humans for qualification, context, trust and conversations. The team is considering AI SDR tools as a substitute for traditional prospecting capacity. It can take over parts of the workflow. Whether a role can change depends on the remaining conversation work, review effort and customer outcomes. A vendor demonstration is not a staffing business case.

What the public evidence shows

Microsoft describes KPN connecting Salesforce, Outlook and Teams to support meeting preparation, proposal drafting and CRM updates.

Practical takeaway: Assisted administration is evidence for task redesign, not evidence that an entire sales role can be removed.

Evidence limit: Assisted seller workflows in one organization. This does not demonstrate headcount replacement or guaranteed sales uplift.

Separate preparation from buyer conversations

Use AI for research, enrichment, routing and draft generation; use humans for qualification, context, trust and conversations.

Use the capacity-versus-conversation decision below as a working method. Adapt its criteria to your own sales cycle and data; it is not a validated industry benchmark.

Compare fully loaded costs per accepted opportunity

Illustrative comparison: an agent creates twice as many drafts, but each needs correction and the AE rejects most meetings. That is not twice the sales capacity. Compare accepted opportunities and downstream progression, including the person supervising the agent.

Keep a human path for ambiguity

Cost per accepted opportunity = software, data, implementation, supervision and allocated salary cost divided by AE-accepted opportunities. Hold ICP and qualification rules constant.

Can an AI SDR replace an SDR role?

It can take over parts of the workflow. Whether a role can change depends on the remaining conversation work, review effort and customer outcomes. A vendor demonstration is not a staffing business case.

How should you measure ai sdr vs human sdr?

Cost per accepted opportunity = software, data, implementation, supervision and allocated salary cost divided by AE-accepted opportunities. Hold ICP and qualification rules constant.
