Numbers

  • ~$2,000 saved per study
  • Submission-to-validated-data: days → minutes
  • Same-week reporting on purchase behavior now feasible

Problem

Longitudinal purchase research requires validating that respondents actually bought what they say they bought. The traditional workflow involved a hybrid of human review and brittle OCR pipelines across receipts, online order confirmations, and product-screenshot submissions — slow, expensive, and inconsistent across receipt formats and retailers.

Approach

Replaced the hybrid review with a full AI-driven extraction pipeline. Multimodal models handle the visual variability across receipt types; a structured-output layer normalizes the extraction into the schema the analytics layer expects; an exception queue routes only true edge cases to human review.

Outcome

Roughly $2,000 saved per study. More importantly, the time from submission to validated data dropped from days to minutes, which changes what’s possible methodologically — same-week reporting on purchase behavior rather than weeks-out.
