Custom Billing Frequency or Manual Interface Date Override or allow mass updates to Bill schedule

Today, Client creates multi-year contracts with their customers, however, the bill schedule may/may not confirm to a standard frequency and customers may want full upfront billing not on contract start date but on a specific date in future within the contract term.

Example – 3 Year Contract with Client ABC for USD 12000 from Jan’24 to Dec’26 with Standard Yearly Frequency created on 10-Jan-2024
, The Bill schedule can either be for each year i.e. Jan’24 to Dec’24, Jan’25 to Dec’25 and Jan’26 to Dec’26. Or they can create a custom bill schedule depending on customer requirement - a. full upfront billing not on contract start date but on a specific date in future within the contract term or b. custom payment schedule.
