Set the number of points required to be upgraded to the next tier. The set-up with works with point thresholds:
Bronze 0 - 100 points
Silver - 100 - 500 points
Gold - 5000 - 1000 points
=> All earning rules can be linked to the tier allowing to give a points accelerator to higher tiers.
=> Pricing can be tailored for each tier.
Note - if a customer is manually assigned to a tier then no downgrade action will happen.
Tips: Tiers names should be related to your business
