[🔗](https://github.com/jeffhuen/tiger_stripe/blob/main/lib/stripe/params/price_create_params.ex#L192)

Nested parameters.

# `t`

```elixir
@type t() :: %Stripe.Params.PriceCreateParams.Tiers{
  flat_amount: integer() | nil,
  flat_amount_decimal: String.t() | nil,
  unit_amount: integer() | nil,
  unit_amount_decimal: String.t() | nil,
  up_to: map() | nil
}
```

* `flat_amount` - The flat billing amount for an entire tier, regardless of the number of units in the tier.
* `flat_amount_decimal` - Same as `flat_amount`, but accepts a decimal value representing an integer in the minor units of the currency. Only one of `flat_amount` and `flat_amount_decimal` can be set. Format: decimal string.
* `unit_amount` - The per unit billing amount for each individual unit for which this tier applies.
* `unit_amount_decimal` - Same as `unit_amount`, but accepts a decimal value in cents (or local equivalent) with at most 12 decimal places. Only one of `unit_amount` and `unit_amount_decimal` can be set. Format: decimal string.
* `up_to` - Specifies the upper bound of this tier. The lower bound of a tier is the upper bound of the previous tier adding one. Use `inf` to define a fallback tier.
