Annual billing option?

Is there an annual subscription option for any of the billing plans?

unfortunately they seem not to support annual … but might plan to - a bit ambiguous …

billing per se should be improved IMHO …
like being able to load credits for the future / allow with a separate login to only download invoices etc.

I do not know how the feature requests and implementation status is handled … there is one link i came across though it talks about apps … billing though is a central not an app feature IMHO

to my above question / comment about billing invoices …
it seems, the current prefered option from Cloudflare to get billing invoices, without exposing the whole DNS to manipulation from the financial team is to use the Cloudflare API and limit what the api-user is allowed to do
