Payout bonuses
Both you and the referred business will receive payout tiered payouts based on referred business' spend in the first 90 days:
$10,000 cumulative card spend in 90 days - The referred business will earn $100
$25,000 cumulative card spend in 90 days - The referred business will earn $250
$50,000 cumulative card spend in 90 days - The referred business will earn $500
If two or more businesses have the same director or owner they would not be eligible for the referral bonus. Additionally, the referred company cannot have the same owner or admins.
