when doing 3 months 01/04/26 to 30/06/26 on custom billing cycle has only 30 days for may ?

Hi, I’m not quite sure what you mean by “only 30 days for May.” Could you please send us a screenshot showing the issue?

Please note that custom billing periods are calculated by time: the start time is included, but the end time is excluded. To include all of April, May, and June, please set the period from 2026-04-01 00:00 to 2026-07-01 00:00.
