### Answer
I don't have information about when monthly fixed payments will be implemented based on the available sources. Retell currently uses post-usage billing, meaning you're charged at the end of each billing period based on actual usage rather than a fixed monthly fee [(1) ](
) . There's no recurring subscription to cancel on the pay-as-you-go plan—you're only charged for usage you actually incur .
If you need information about potential fixed payment plans or enterprise pricing options, I'd recommend checking out the [enterprise plan page](
) or reaching out to the Retell team directly for the latest updates on billing options.
