Bill8:Risk — fraud prevention

Fraud prevention as a gate, not a report: declarative rules and velocity checks screen charges before money moves, sanctions screening runs on the merchant and payer surfaces, and a review queue adjudicates the gray zone.

Use cases​

  • Pre-charge screening — every charge passes the rule set (velocity, geo, amount thresholds, custom rules) before the rail call; a blocked charge never moves money.
  • Sanctions screening — merchant onboarding and payer identity screen against sanctions lists with full audit.
  • Review queue — flagged transactions queue for manual adjudication; dispositions are auditable and terminal states never regress.
  • Rule authoring — rules are data; a merchant's fraud team tunes the rule set without a release.
