LedgerMatch

Bank Reconciliation Software for Bookkeepers in Chicago, IL

Chicago's 150,000-plus small businesses — spanning manufacturing, food service, professional services, and tech — generate the transaction volume that makes manual bank reconciliation one of the biggest time drains for Midwest bookkeepers. Chase is the dominant commercial bank in Chicago, but BMO and Wintrust each have strong local market share, and their CSV formats differ significantly. LedgerMatch handles all three automatically, matching every transaction and flagging splits, duplicates, and timing differences in a single pass.
