1) The problem →
I'd like to sell add-ons on top of Memberstack. Eg: A $99 subscription plan, with the option to add single-products to it.
2) Why is this important →
I'd like to upsell services to my members.
3) What's your plan B →
Send a Stripe invoice manually and have the customers accept it. Build a hacky way to let users select a product and then bill them separately. Build my own Stripe integration.
4) Possible solutions we could build for you → Allow add-ons on top of subscription plans.
