Overdraft / NSF Fee Recomputation

Independently recomputes overdraft (OD) and non-sufficient-funds (NSF) fee events from a pasted posted-transaction ledger, your declared opening balance, posting-order policy, and fee schedule, then diffs the recomputed totals against what the core actually charged, if you supply that. Posting order and every fee-schedule term are yours to declare; this tool never chooses or infers them.

⚠ This is an independent recompute and receipt, not a core alternative, not a vendor audit, and not an endorsement claim by any core vendor or platform (Fiserv, Jack Henry, FIS, Finastra, Episys, SilverLake, DNA, Premier or otherwise). A divergence is an arithmetic finding about the figures you supply, never a determination that a fee was charged incorrectly or impermissibly. Batch, pasted-export only: no real-time or in-line posting integration of any kind.
