The nature of our business is such that our repeat customers move on a regular basis and change their addresses every 12mths upwards. We have 2 options. 1 is to use the old card and update their details which means we lose the previous addresses competely. 2 is to set up a new card with the new address and keep the old card on the system which means we can have multiple cards for long term customers which just clogs up the system and is confusing. My suggestion is to add a link from the new card to the old card by way of a "more info "tab or link and so the card on the system is the current card but has access to past info. This would be an invaluable business tool for us.
