👋 happy to help

#

this is highly advanced as a pricing model and I'm unsure whether there's an easy way to model this in Stripe

#

I would strongly suggest keeping track of this in your own system

#

and reporting it once per cycle to the subscription

#

by using the add_invoice_items https://stripe.com/docs/api/subscriptions/update#update_subscription-add_invoice_items

Hey @storm berry thanks for the quick reply.

Yeah I am maintaining billing metrics in the system, so I have a definitive "source of truth" at all points of a billing cycle to say e.g. "you used 3.6 users @ £5/user = £18".

#

Can I update the additional invoice item as I go along, or would I need to remove it and re-add it daily as the figure changes?

Ideally I would like the next invoice to always reflect the cost as we know so far in that billing cycle.
