Cash Payment Compliance Review

Read-only Tally review for cash payments above the configured limit, same-day party aggregation and possible split-payment patterns. The accounting planner below uses only actual source payment dates supplied by the user; it never invents or changes dates.

Cash Payment Entry Allocation — Actual Source Dates
