Case study · Overnight batch drift
A mid-size wallet team in Incheon joined Desk Review Path after day-two balances disagreed with scheme reports for three consecutive Fridays. Together we mapped cut-off assumptions against the acquirer calendar, then rebuilt the sample that finance had been rejecting as “too anecdotal.”
Within one cycle they logged a repeatable 47-minute file delay that had been absorbed into “normal variance.” The finding cited Module 3 techniques from Fintech Settlement Audit Mastery and used Scaleupnow’s evidence-pack outline. Residual risk remained for weekends with public holidays—documented rather than ignored.
