With the new release, each subscription on Project X gets a dashboard showing per-quota usage for each billing period.
Before, it’s already been possible to use soft quotas. It enabled API vendors to offer overages in their subscription plans. The API user would see the remaining quota (and potential overuse) in HTTP response headers but that wasn’t particularly useful to API vendors, as they were lacking visibility on quota usage above the soft limit.
While with hard quotas it’s not of a big concern since subscription plans with only hard limits imply flat fee which can be invoiced at either the beginning or the end of a billing period, in case there are soft quotas, the monthly/yearly/etc. fee is dependent on the actually used quota units.
From now on, API vendors can see actual usage numbers and use those to invoice customers at the end of the billing period.
