Payment on Account
for osCommerce Online Merchant v2.2
This module allows customers to be given credit accounts from the admin screen. Once set, the customer will be able to choose paying on account as a payment option. For customers without accounts, this option will not be shown, thereby ensuring only pre-authorised customers have this option.
Working on my site now, if you want to test it out:
