What does an authorised representative cost per year in total for a small electronics seller?

The pure Stiftung EAR fees for a single-product seller are around €140–160 per year (four quarters at €32.80 = €131.20, plus initial registration of around €9.50 and warranty check around €3.80). However, you also pay the authorised representative service provider's own fees, which typically run €50–300 per year depending on scope and service. Larger product ranges become proportionally more expensive — a product line with ten device categories can quickly cost three to four times as much. It is worth calculating total costs before you register.
