Cultural Tip
In German‑speaking countries payment deadlines are usually expressed with ‘fällig bis’ or ‘bis zum …’. In formal business communication you would replace the impersonal ‘man’ with ‘Sie’ (e.g., ‘Bis wann müssen Sie bezahlen?’) to show respect. Late payments often incur a ‘Mahngebühr’ (reminder fee), so it’s good to ask the exact date.
