  "contentText": "Payment processing is the infrastructure that turns your membership site from a content platform into a revenue-generating business. Every subscription signup, tier upgrade, lifetime purchase, and affiliate commission payout flows through your payment setup. Get it wrong and members can't pay you; get it right and billing runs silently in the background while you focus on growth.\n\nThis guide covers payment processing setup for the custom membership site script at /membership-scripts/membership-site — Stripe and PayPal integration, subscription logic, webhook configuration, and common troubleshooting. Pair this with our membership levels and pricing tiers guide to ensure your payment amounts match your tier structure.\n\nStripe vs. PayPal for Membership Sites\n\nThe custom membership script supports both Stripe and PayPal. Most platform owners use Stripe as primary and PayPal as secondary — here's why:\n\nStripe (Recommended Primary)\n\nNative subscription billing with automatic recurring charges\nWebhook-driven membership status updates — instant tier activation on payment\nCredit card, Apple Pay, and Google Pay support\nDetailed transaction reporting and export for accounting\nLower dispute rates with strong fraud detection tools\n2.9% + $0.30 per successful transaction (standard US pricing)\n\nPayPal (Recommended Secondary)\n\nPreferred by a segment of internet marketing audience who don't use credit cards\nPayPal balance payments reduce friction for repeat buyers\nSubscription billing available through PayPal billing agreements\nUseful for affiliate commission payouts — most affiliates expect PayPal\nSlightly higher fees on some transaction types; acceptable as a secondary option\n\nOffer Both at Checkout\nDisplaying Stripe (credit card) and PayPal options at checkout typically increases conversion 10–15% compared to credit card only. Some members trust PayPal's buyer protection; others prefer direct card billing. Supporting both captures both preferences.\n\nStripe Setup for Your Membership Script\n\nFollow this sequence to connect Stripe to your custom membership platform:\n\nCreate a Stripe account at stripe.com — complete business verification before going live\nGenerate API keys — publishable key (frontend) and secret key (backend) from the Stripe dashboard\nEnter keys in script admin — Payment Settings section of your membership admin panel\nCreate Stripe Products and Prices — one product per membership tier with monthly and annual price variants\nMap Stripe Price IDs to script tiers — link each tier in the admin to its corresponding Stripe price\nConfigure webhooks — point Stripe webhooks to your script's webhook endpoint URL\nTest in sandbox mode — complete test signups, upgrades, and cancellations before switching to live keys\n\nEssential Stripe Webhook Events\n\ncheckout.session.completed — Activates membership on successful initial payment\ninvoice.payment_succeeded — Renews membership on recurring billing cycle\ninvoice.payment_failed — Triggers dunning (retry) and eventual membership suspension\ncustomer.subscription.deleted — Handles cancellation and tier downgrade\ncharge.refunded — Reverses membership access and affiliate commissions on refunds\n\nSubscription Billing Logic and Member Lifecycle\n\nUnderstanding how the script handles billing events prevents support headaches and revenue leaks:\n\nSignup — Member selects tier, completes checkout, webhook activates account immediately\nRenewal — Stripe charges automatically on billing date; webhook extends membership period\nFailed payment — Script retries per Stripe dunning settings; member notified to update payment method\nGrace period — Configure 3–7 day grace after failed payment before access suspension\nUpgrade — Member selects higher tier; prorated charge for remainder of billing cycle\nDowngrade — Takes effect at end of current billing period to avoid refund complexity\nCancellation — Member retains access until period end; no further charges\nLifetime purchase — One-time payment; no recurring billing; permanent tier assignment\n\nAnnual Plans Reduce Churn\nAnnual subscribers churn at roughly half the rate of monthly subscribers. Configure annual pricing at 8–10 months of monthly cost. The upfront cash flow and retention improvement make annual plans one of the highest-impact pricing decisions for membership sites.\n\nReady to Launch Your Own Custom Membership?\nCustomSitesPro.com builds and hosts a branded custom membership on your domain — AI branding, hosting, and setup included.\nView Custom Membership\n\nPayPal Setup and Affiliate Payouts\n\nPayPal serves two roles on your membership platform — member checkout option and affiliate commission payouts:\n\nPayPal Checkout Integration\n\nCreate PayPal Business account and complete verification\nGenerate REST API credentials (Client ID and Secret) from PayPal Developer dashboard\nEnter credentials in script admin Payment Settings\nConfigure PayPal billing plans matching your membership tiers\nTest sandbox transactions before enabling live mode\n\nAffiliate Commission Payouts via PayPal\n\nYour affiliate program — configured per our membership site affiliate program setup guide — pays commissions on successful referrals. PayPal Mass Pay or Payouts API batch-processes affiliate payments on your published schedule. Collect PayPal email addresses during affiliate registration.\n\nPayment Testing Checklist Before Launch\n\nNever go live without completing every test in sandbox mode. Use our membership site launch checklist as your master pre-launch timeline:\n\nNew member signup — each tier, monthly and annual, via Stripe and PayPal\nTier upgrade — verify proration charges correctly and access updates immediately\nTier downgrade — confirm it schedules for end of billing period\nSubscription renewal — simulate successful recurring charge and membership extension\nFailed payment — verify dunning emails send and grace period activates\nCancellation — confirm access continues until period end, then suspends\nRefund — verify membership deactivates and affiliate commission reverses\nLifetime purchase — one-time payment activates permanent access\nWebhook delivery — check Stripe/PayPal dashboards show successful webhook responses\n\nSwitch to Live Keys Only After Full Testing\nThe most common payment launch mistake is switching to live API keys before completing sandbox testing. A broken checkout on launch day costs signups you can't recover. Test every tier path, every payment method, and every webhook event in test mode first.\n\nCommon Payment Issues and Fixes\n\nMember paid but account not activated — Check webhook delivery in Stripe dashboard; verify webhook URL and signing secret\nDouble charges on upgrade — Ensure upgrade flow modifies existing subscription rather than creating a new one\nAffiliate commission not calculating — Confirm webhook processed payment before commission hold period elapsed\nPayPal checkout redirect fails — Verify return and cancel URLs match your domain exactly\nAnnual plan not renewing — Stripe handles annual renewals automatically; verify price is set as recurring annual, not one-time\nMember can't update payment method — Enable Stripe Customer Portal or provide in-account payment update link\n\nCompliance, Taxes, and Business Considerations\n\nPayment processing carries business obligations beyond technical setup:\n\nTerms of service and refund policy — Publish clear policies before accepting payments\nSales tax — Stripe Tax or manual configuration for jurisdictions requiring collection\nPCI compliance — Using Stripe/PayPal hosted checkout means you don't store card data; compliance is simplified\nChargeback response — Maintain transaction records and delivery proof for dispute resolution\nAccounting integration — Export Stripe/PayPal reports monthly for bookkeeping\n\nFor total platform cost context including payment processing fees, see our cost to build a custom membership site guide.\n\nPayment-Ready Membership Platform from CustomSitesPro\n\nCustomSitesPro configures Stripe and PayPal integration during done-for-you membership site setup — API keys connected, tiers mapped to payment products, webhooks configured, and sandbox testing completed before your launch date.\n\nExplore the custom membership site script at /membership-scripts/membership-site and launch a platform where payments work reliably from the first member signup.\n\nReady to Launch Your Own Custom Membership?\nCustomSitesPro.com builds and hosts a branded custom membership on your domain — AI branding, hosting, and setup included.\nView Custom Membership",
