# Create a limit tier

> When a customer's lifetime paid amount (succeeded payments less succeeded refunds) in currency reaches level_minor, its customer limits per interval rise to amounts.

<api-operation method="POST" path="/v1/businesses/{biz}/spend_limit_tiers">
<template v-slot:docs="">

When a customer's lifetime paid amount (succeeded payments less succeeded refunds) in `currency` reaches `level_minor`, its customer limits per interval rise to `amounts`. A customer never drops to a lower tier after a refund or a chargeback. Up to 10 per currency.
