Email when charges go unpaid
When a charge is larger than what is left of your balance, the rest becomes unpaid charges and new work waits until
they are paid. Your billing contact and the organization’s Owners and Admins now get an email saying how much is
unpaid, at most once a day, along with an ArrearsPosted Event and a billing.arrears_posted webhook. Add credits
with nodus billing top-up to pay them and resume.
