Anchor on total payment volume growth, authorization success by issuer and network, blended take rate, and loss rates from fraud and chargebacks. Track instant payout adoption, dispute rate per thousand transactions, and operational cost per dispute. Healthy programs sustain domestic authorization above ninety percent, chargebacks well under one percent, and fraud losses inside risk appetite while monitoring decline reasons, 3DS routing impacts, soft declines versus hard, issuer bin-level behavior, and settlement timing that affects cash availability.
Tie acquisition and underwriting quality to approval rate, cost of funds, first payment default, and loss vintage curves. Watch non-performing balances, recovery effectiveness, repeat borrowing, and CAC payback on attributable, risk-adjusted contribution. Early cohorts often show volatility; disciplined programs stabilize with robust identity verification, explainable credit models, post-origination engagement, and collections workflows that respect regulation while protecting unit economics. Benchmarks demand segmentation by product, ticket size, channel, geography, and merchant category.
