bank transfer with reference

Hi all, good day.

im just wondering if i can have a bank transfer that generates code for reference.

for example, when comes to payment method,customer will be given an option.

1. Bank transfer - option Bank A Option bank B
if they select bank A, reference code will be generate BankAXXXXX, or else Bank B, BankBxxxx

2. pay by account credit.

once check out, the order will be set as pending and subtract the stock. and the transaction will be recorded on transaction table with extra column "reference no" - once approve by admin it will be informed or recoreded on transaction

also, customer able to buy account credit on my account, when they click buy, open cart will generate code and recorded on transaction together with reference code that been auto generated. once the admin verified then approved then release the amount to their account.

has someone manage to have this kind of enviroment before?


thank you.
