Post a customer receipt to the value that you want to transfer in that customer account.  You can use your normal bank account for this but make a note of the date and value that you use and put the word CONTRA in the reference (purely for identification, the reference itself does nothing special).  Then post a supplier payment for the same value and date, same bank account, again with the ref CONTRA.

When you next reconcile your bank account, match off the two contra transactions, so it has no imipact on the overall bank balance.
