Can I code this? A Subscription Billing Management Tool
Stripe Subscriptions handles the actual recurring charge and card storage for you — the real work is your own dashboard for plans, upgrades, and what happens when a payment fails.

Why CanICodeThis says Borderline
Creating a Stripe Subscription when a customer signs up for a plan is a well-documented integration
A dashboard listing customers, their plan, and billing status is ordinary CRUD
Letting a customer upgrade or downgrade their plan is a bounded Stripe API call
The parts that'll cause problems
Failed-payment recovery (a card expires mid-subscription) needs Stripe's dunning tools wired in properly, not just retried silently
Prorating charges correctly when someone switches plans mid-cycle needs real care to get the math right
Usage-based billing (charging by consumption, not a flat plan) is a genuinely different, harder billing model

The build prompt
Build me a subscription billing dashboard: use Stripe Subscriptions for recurring plan billing, with a dashboard listing customers, their plan, and billing status, and letting a customer upgrade or downgrade. Lean on Stripe's built-in retry and dunning emails for failed payments rather than building your own. Skip usage-based billing for v1.
