Grant (credit grant)
Free credits issued to a wallet, with an expiry — used for trials, make-goods or launch promos. Grants burn before paid credits.
A grant (or credit grant) is a block of free credits issued to a customer's wallet, typically with an expiry date, used for trials, promotional launches, or as a make-good after an issue — distinct from credits the customer actually paid for.
It matters because a grant and a paid credit need to behave differently even though they look identical as a single balance number to the customer: a grant is meant to be spent within a window and then disappear, while a paid credit represents money the customer handed over and should never simply vanish.
In practice, this means a wallet needs to track grants and paid credits as separate internal balances even while presenting one combined number, and burn grants before paid credits — so a promotional allowance gets used first, and a customer's actual money isn't quietly consumed by usage that was meant to be covered by the free grant.
The common pitfall is burning credits in the wrong order — paid credits before grants — which means a customer's real money disappears into a promotion that was going to expire anyway, and the resulting 'why did my paid balance drop' support ticket is difficult to explain away after the fact.
