I would hesitate to use the billing system again after difficulties
My experience with the billing and payments system was disappointing enough that I would be reluctant to use it again without major improvements. Early on, I encountered errors with invoice generation that required multiple calls to support. Each time something went wrong, the process of getting a correction was slow and required repeating information, which was frustrating and time-consuming. The sign-up and onboarding for payments seemed fine initially, but the real trouble started when exceptions occurred. On the one positive side, at least the automatic updates seldom caused further billing errors, so that was a relief. If the system were more transparent and responsive to issues, I'd consider giving it another try. But as it stands, the effort needed to resolve payment errors does not feel worth it for me at this time.
