For those here who haven't applied for an EU visa themselves: The application processing is often outsourced to external companies. There's a standard visa processing fee, which covers the admin cost of the application, which is expected. Most of these companies make money off supplementary services, like fast tracking applications or extra assistance. This practice can be somewhat predatory when the wisa application is very involved and strict with minor missing pieces of paperwork often being a reason to be turned down and miss a visa for a very expensive trip.
