Anyone knows how to handle custom billing schedules in NetSuite? I know I can create a billing schedule to any terms I want, example, monthly for 4 months or a year, etc. But how about when I get sales order that don't follow the predefine billing schedules, do I just create a new one each time? Anyway to automate this with a script? I don't want to create a billing schedule each time. It seems like fix interval billing can solve this but its link to a project date
