This depends on when you make the payment and the cut-off time. The cut-off time is the time when the bank stops sending out transactions requested during the day.
If you make a transfer in EUR before the cut-off time, it will arrive in the recipient's account on the same day.
If you make a transfer in EUR after the cut-off time, it will arrive the next day. Transfers made in other currencies take a little longer, but they should arrive within 2 business days. We process all transfers according to Belgian time.
