Not that it helps, but I think this is only a problem if you’re paying by credit card.
If your company is on an enterprise plan, at least for us all of the limits are pre-negotiated and prepaid, and you aren’t billed for overages (although if you consistently overage, sales will start badgering you to negotiate a limit increase, but my experience is you can simply ignore their demands and they eventually go away)
It does drive me crazy that their enterprise tier “caps” bandwidth. Our company overaged on one of our domains, so we moved the domain out of our enterprise license onto a self-serve plan, and like magic, back to unlimited bandwidth.
My Cloudflare enterprise order form has costs for overages for Workers and the following language about everything else:
> If Customer exceeds any of the Total Quantity for the Services below, Cloudflare will invoice Customer in arrears at a rate that corresponds to the rate set forth in the table after this one labeled “Excess Usage Pricing.” If no such Excess Usage Pricing table has been added by the Parties to this order form or if such table does not include the Service(s) for which Customer has exceeded the Total Quantity, then the Parties will negotiate in good faith an increase in the Fees for such Service(s). Should the Parties fail to reach an agreement on an increase within thirty (30) days of Customer’s receipt of notice from Cloudflare that Customer has exceeded its usage cap for the Service(s), Cloudflare will have the right to immediately terminate such Service for its convenience, and without liability to Customer or any third party.
