Frequently asked questions

What to know before importing.

Are my files uploaded to the Internet?

No. Price list contents are read and compared in your browser. TarifDelta does not upload them to a server.

Which formats are supported?

XLSX, XLS and CSV, within the limits shown in the import area.

Does TarifDelta replace my ERP?

No. It compares two versions of a price list and exports the changes so you can continue your existing workflow.

What happens with duplicates or ambiguous units?

The row is flagged as “Needs review” rather than inventing a potentially incorrect price variation.
