If you pay by ACH bank transfer your transaction will take between four and five banking days to complete. This may be faster for returning customers, but it is not guaranteed.
If you pay by domestic wire transfer your transaction will take between one to two banking days to complete.
Note, payments can only occur during banking hours in the US and deposits only occur during banking hours in Mexico.
Also note, US domestic wires tend to have a daily cut-off time in the middle of the day, so please send them in the morning for faster processing.
