I think it would be a cool idea to have "tab achievements". For example; every so many months (6 or 12 months), Koodo members earn a "tab achievement" on their account. This gives them $5 or $10 taken off of what they owe on their tab, or added to their positive balance to help them purchase a phone sooner. These achievements will show up in the Koodo members account under "Achievements". Each achievement will have a different badge associated with it. There can also been extra ways for Koodo members to earn badges. Example: Maybe there will be a badge for referring a friend to sign up for Koodo services.
