40-Point SDR Outsourcing Evaluation Checklist
Score SDR vendors on data quality, rep ratios, qualification rigor, and cost transparency. Surface the data and integration fees that quietly inflate every quoted base price.
Scoring Framework
Rate each answer 1 to 5 based on specificity and depth. Vendors that consistently score below the midpoint tend to deliver on the marketing pitch but disappoint on actual pipeline, usually because the gaps in data quality, qualification rigor, or cost transparency compound across the contract year.
