计费模块
我正在推出一项小型服务,并计划按月收费(例如,广告上的收费为每月 10 美元)。 我现在正在开发计费模块,但想知道一点:
我计划在客户第一次注册时向他们计费,然后定期向他们计费。 回答我的问题——有些月份的天数少于 30 天。 按月计费是否意味着 30 天的间隔,还是 28-30 天之间的任何时间间隔都被视为每月间隔?
我原本计划收取 30 次,因为这似乎是客户所期望的,但我也很好奇是否有些公司以 30 天以外的固定间隔收费。
I'm launching a small service and plan to charge monthly (eg- will be advertised as $10 monthly). I'm working on the billing module right now but was wondering about a small bit:
I plan to bill customers when they first register and then at regular intervals thereafter. Getting to my question- Some months have less than 30 days. Does monthly billing imply exactly a 30 day interval or would anything between 28-30 days be considered a monthly interval?
I was planning on doing 30 because it seems that's what customers would expect, but I'm also curious if some companies charge at a fixed interval other than 30 days.

假定每月每年计费 12 次,而不是每 30 天计费一次。
最好是在该月的原始计费日期的周年纪念日进行计费。 如果当月的天数少于原始计费 DOM 的天数,则在当月的最后一天计费,但在下个月的周年纪念日再次计费。
Billing monthly is assumed to be 12 times per year, not once every thirty days.
Preferably, billing should be on the anniversary of the original billing date of the month. If the current month has fewer days than the original billing DOM, bill on the last day of the current month, but on the next month, bill again on the anniversary day.
