Täsmäytys

Täsmäytys is a Finnish term that translates roughly to reconciliation or alignment. In everyday use it refers to the process of bringing two or more records, balances, or data sources into agreement. In professional contexts, täsmäytys is a standard control procedure used to detect and correct discrepancies between datasets, ledgers, or reports.

In accounting and finance, täsmäytys most commonly denotes bank reconciliation and inter-period reconciliations. The process typically involves collecting relevant records (for example, a general ledger, subsidiary ledgers, and a bank statement), performing a line-by-line comparison, and identifying mismatches caused by timing differences, data entry errors, or missing transactions. After investigating, adjustments are posted to bring the records into agreement. The outcome is a documented, reconciled balance and an audit trail.

In information technology and data management, täsmäytys describes data reconciliation tasks across sources such as ERP systems, customer records, or transactional logs. Methods may include matching on key identifiers, deduplication, and resolving conflicts between source systems. Effective täsmäytys supports data integrity, accurate reporting, and better decision making.

Etymology and usage: the verb täsmää means to agree, fit, or match; täsmäytys is the resulting process or state. The term is widely used in Finnish accounting, banking, and IT settings, and it can be specified further as pankkitäsmäytys (bank reconciliation) or varaston täsmäytys (inventory reconciliation) depending on context.
