Verify checkout works at each price point: compliance diagnostic, sponsorship, and accelerator tiers.
Why it matters: the test card (4242 4242 4242 4242) only exercises Stripe test mode. The live payment rail is not proven until a real charge passes through. A broken checkout or wrong currency on launch day means lost revenue and a bad first impression.
Pick one path and tell CC which you chose:
Option A (safest): CC runs each checkout flow with test card 4242 4242 4242 4242. Confirms code path works. Accept the live payment rail is unproven until first real customer.
Option B (proves live rail): You make one real, low-value live charge at each tier and keep it (treat as your own purchase, do not refund). Cleanest way to prove the live rail works without the prohibited real-card-plus-refund pattern.
Skipping is also valid: launch and let the first real prospect prove the rail.
Done when: you tell CC which option you picked. CC executes Option A automatically, or confirms one live charge per tier appears in the Stripe dashboard for Option B.
