How much does an EU Responsible Person service cost per year, and are hidden fees common?

Standard costs range from €150 to €500 per year, depending on your product portfolio's complexity and how often technical documentation needs updating. Some providers charge separately for edge cases such as incident reporting, complex recalls, or extraordinary documentation. That's legal, but frustrating if you don't know in advance. When seeking a quote, ask directly: are incident reports included? Do regulatory enquiries cost extra? How many declarations of conformity revisions per year are in the fee? This way you avoid nasty surprises at year-end.
