NeiboCheck: Nebenkosten-Check

¿Qué es NeiboCheck: Nebenkosten-Check?

NeiboCheck helps renters in Germany do a first-pass review of a `Nebenkostenabrechnung` before reacting. Instead of acting like legal advice, it flags suspicious or manual-review items, keeps deadlines visible, and shows what to question next. It is built for the moment when a high `Nachzahlung` lands and the renter is not sure what deserves a second look first.
