Backup / Data Export Center
Export and re-import your complete Business Center profile as an encrypted .itss file — no cloud required, never in plain text.
Export
Creates an encrypted .itss file with your company data, logo, customers, items, documents, cash-book and payroll entries. Encryption is mandatory — without the chosen password, the file cannot be read.
Without this password the file is unrecoverable — it is stored nowhere.
Import
Choose a previously exported .itss file and enter its password.
To edit: import the file → make changes in Stammdaten-Center → export again as .itss here.
