Tositeisiin

Tositeisiin is a Finnish term used in bookkeeping to refer collectively to receipts, vouchers, and other documents that prove business transactions. The set typically includes cash register receipts, supplier invoices, travel tickets, and bank statements showing payments.

Purpose and function: Tositteisiin provide audit evidence for entries in accounting records and tax reporting. They verify the occurrence and amounts of expenses and revenues, support deductions for VAT, and enable reconciliation of accounts. In practice, they are stored in physical folders or as digital scans and linked to the corresponding accounting entries.

Regulatory context: In Finland, businesses are generally required to retain tositteet for a defined period after the financial year ends, commonly six years, to satisfy tax- and accounting-related requirements. Digital copies are accepted if legible and authentic; regulations require reliable storage, traceability, and the ability to reproduce documents if authorities request them.

Management and archiving: Organizations index and categorize tositteisiin by date, supplier, and expense type; apply consistent naming; maintain backups and secure access controls; ensure long-term readability through digital formats and file integrity checks.

Modern developments: Electronic invoicing and digital receipts are increasingly common; many companies integrate tositteisiin with accounting software for automatic matching of payments and entries. Regulation continues to evolve to promote digitization while ensuring auditability.
