I’d like to propose adding support for monthly usage‑based charges on annual subscription plans. Currently, usage‑based charges are typically tied to monthly subscriptions, which means I can only offer monthly usage billing when the merchant is on a monthly subscription and not when they’re on an annual plan.
I’ve also seen other developers and merchants talking about similar functionality, so it’s clearly a recurring need in the ecosystem.
Please let me know if it’s already in your consideration and any expected timeline regarding this if present.

Hi @Tanmay_K - you’re right, this is a limitation of the Billing API. Annual subscriptions do not support usage-based charges, and combined time + usage plans are only available on the EVERY_30_DAYS interval. The complex pricing models and combine time and usage-based subscriptions docs both call this out.
This same request came up recently in this thread, where a workaround was discussed. The idea is to create a $0/month subscription with a high capped amount and then bill the annual fee as a usage charge. The tradeoff is that you lose Shopify’s built-in proration and plan change handling, so you’d need to manage that yourself.
I’ve added your feedback to an existing internal feature request for this. No timeline to share, but the more developers who surface this the better visibility it gets with the product team so thanks for raising it here!
