Evaluate Account-Partner Onboarding with Success Metrics

##### Scenario Account-partner team acquires new merchants onto the marketplace, and leadership wants to quantify how well that program works. ##### Question a) Which core success metrics would you report to evaluate account-partner onboarding performance? b) Without randomized experiments, how would you estimate causal impact—e.g., using difference-in-differences? c) If account partners mainly sign seafood restaurants, how would you build a propensity-score or synthetic-control comparison group and which merchant attributes would you match on? d) How would you model the relationship between acquisition cost and incremental revenue, and why might a logistic rather than linear curve be appropriate? ##### Hints Think causal inference, merchant-level covariates (location, cuisine, size, tenure), parallel-trend checks, and diminishing-return economics.
