TÜV Rheinland (Germany)

Although overall costs are somewhat reasonable (as compared with some other figures in this list), some billing positions are quite ridiculous, such as a 120 Euro travel expense reimbursement for an actual travel within range of a 2,80 Euro public transport ticket

55.000€

Fixed times are not complied with

QMS audit and certification worked well. Technical Documentation is still pending for several months without any clear communication or time commitment from the auditor.

for MDR + 13485, approx 35.000€

if you are a long term customer and have a good relationship with the notified body, the cooperation can be uncomplicated. for new companies it is much more difficult i've heard and read.
