Dear @JJ061987,
Welcome back to the Wefugees Community and thank you for reaching out to us again.
I don't think it is a problem, as long as the reference in the bank transfer is clear (like "Aktenzeichen", "Vorgangsnummer" or something similar). May I ask why the person doesn't have any bank account?
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
Meike
