Dual-Mode Billing Architecture

Unite-Hub uses a dual-mode billing system to separate staff testing from real customer payments.

Mode Determination Logic

// From src/lib/billing/stripe-router.ts

// TEST Mode triggers:
// 1. Staff roles: founder, staff_admin, internal_team, super_admin
// 2. Registered sandbox emails (SANDBOX_STAFF_REGISTRY)
// 3. Internal domains: unite-group.in, disasterrecoveryqld.au, carsi.com.au

// LIVE Mode:
// All other users (real customers)

Environment Variables Required

# TEST Mode (for staff/internal)
STRIPE_TEST_SECRET_KEY=sk_test_...
STRIPE_TEST_WEBHOOK_SECRET=whsec_test_...
STRIPE_TEST_PRICE_STARTER=price_...
STRIPE_TEST_PRICE_PRO=price_...
STRIPE_TEST_PRICE_ELITE=price_...
NEXT_PUBLIC_STRIPE_TEST_PUBLISHABLE_KEY=pk_test_...

# LIVE Mode (for customers)
STRIPE_LIVE_SECRET_KEY=sk_live_...
STRIPE_LIVE_WEBHOOK_SECRET=whsec_live_...
STRIPE_LIVE_PRICE_STARTER=price_...
STRIPE_LIVE_PRICE_PRO=price_...
STRIPE_LIVE_PRICE_ELITE=price_...
NEXT_PUBLIC_STRIPE_LIVE_PUBLISHABLE_KEY=pk_live_...
