PC CADDIE stays. We build around it.
Club administration runs in PC CADDIE, as at most clubs. We don’t replace it, we read it: member records mirrored every night, competition calendar and results live, tee times and handicap via the interface, recipients for club announcements straight from the records. Entry for competitions and lessons with your own PC CADDIE account, on the club website. We write nothing into PC CADDIE; that stays with the club office. No second set of member records, no double maintenance.
Replacing PC CADDIE means selling a project. Connecting to it means delivering a system.
